Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Where can I spend bitcoins?

Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.

Merchant Resources

There are several benefits to accepting bitcoin as a payment option if you are a merchant;
If you are interested in accepting bitcoin as a payment method, there are several options available;

Can I mine bitcoin?

Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. If you would prefer to keep it simple there are several good options. You can view the global node distribution here.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
bitcoin BTC 1 bitcoin one bitcoin is equal to 100 million satoshis
millibitcoin mBTC 1,000 per bitcoin used as default unit in recent Electrum wallet releases
bit bit 1,000,000 per bitcoin colloquial "slang" term for microbitcoin (μBTC)
satoshi sat 100,000,000 per bitcoin smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

The Bitcoin Economic Model & The Bitcoin Network Model

Bitcoin's economic model is the foundation for a whole new internet architecture, the Bitcoin network model, but many people dislike the idea of replacing the current TCP model with a 'pay to view' or 'pay per click' model in which the entire internet is run on top of an economic model.
In the Bitcoin model, a mouse click costs 1/10000th of a penny, a google search might cost 1/100th of a penny, a webpage might cost 1/10th of a penny and a Netflix video might cost a penny per minute.
Why is this important? It opens up a whole new realm of possibilities in terms of how you get paid for creating content, and it opens up huge new opportunities for entrepreneurs to open businesses based on micropayments.
In simple terms, an internet based on Bitcoin allows users to set the price at which others can open a connection to them. In other words, if you want to call me, I can choose how much you have to pay to talk to me. If you're my best friend, I can charge you less than a penny per minute. If you're my ex-girlfriend, I can charge you $5 per minute. It's high enough that if you have to talk to me, you can call me, but you won't waste my time... and if you do, I can always raise the price again.
It sounds like a frivolous example, but take the model and apply it to advertisers. How many adverts do you get bombarded with every day that you don't want to see? In your youtube videos for example? Or on your facebook feed. Well, in the bitcoin model, where the internet itself is built on bitcoin, you can charge advertisers to open a connection to you. So that Grammarly advert you hate? You can charge them $100 to watch their advert. Or, you can set a low rate, like $1 and if they think you're worth it, they can set a budget as to how many advertising dollars they're willing to waste on trying to acquire your custom. But crucially, YOU GET THEIR CASH.
It's a much better model. If you don't want to see any Grammarly adverts you just set the rate at which Grammarly can connect to you to $10,000 per second and never hear from them again.
In Dimely, you can set the rate at which others connect to you. So let's say you're an English teacher, or an online Psychotherapist, or a Legal Consultant. You can charge customers for your time. You set your rate per minute, and they connect to you for as long as they can afford to. You can even negotiate the price in the call, and adjust your price for different clients and the blockchain acts as a permanent record of the exchange which is useful for contractual purposes.
Once you get your head round this fundamental idea, then you start to realize the possibilities. You can charge people to open a connection to you, and your content.
In an enterprise situation, you might be a Hollywood movie studio, publishing a movie to the blockchain. It might cost you $100,000 to upload a single movie at today's prices, but you could stream the movie direct to people's wallets, and they'd pay $1 a time (for example). If you have a million views, you've just made $900,000 revenue. That's a good peer-to-peer distribution model for Hollywood movies, but you can do the same for music, self produced or mass produced, as well as art and literature, blogs, websites, and any other kind of data you can think of.
That's Bitcoin.
Bitcoin is BSV.

Summary of Tau-Chain Monthly Video Update - July 2020

Karim
Agoras Live: Five functionalities complete: 1. Registration 2. Login 3. User Profile Page 4. Calendar 5. Categories List 6. Wallet Screen Payments: Decided that implementing lightning would be too complex. Instead, we decided to implement our own micropayment mechanism using the native BTC multisig addresses. We are going to use the Omni wallet for payments. TML: Continued debugging, getting a TML demo and test cases ready. Hiring: More hiring efforts to increase team size. Timelines: Committing ourselves to a release of Agoras Live and a basic version of discussions in TML in 2020.
Umar: Been working on making improvements to the context free grammar parsing. We now are able to add constraints to productions in the grammar, allowing us to recognize grammars that are context sensitive. Developed test cases for that, too.
Tomas: Fixed issues in TML and ran several steps in a TML program. Now adding more tests to make sure everything is stable and won’t break. Also been working on a TML tutorial, a recorded script based on the intro to TML which was contained in the TML Playground. Also new features are going to be covered such as arithmetics.
Kilian: More outreach & follow-ups to potential partner universities. Positive response by a professor based in Toronto, presented to him our project. Also, response by KULeuven, Belgium, who unfortunately don’t see a good fit in our project. We’ve had one applicant for the IDNI Grant program and currently are evaluating his proposal. Also, we’ve had an applicant from Bangalore, India for the IDNI Ambassador program and we also have been discussing his proposal. Translation Bounties: We’ve had the blog post “The New Tau” translated to Chinese and have been reviewing the translation. We are going to publish the translation on our website and on the Bitcointalk Chinese forum section. Still to be claimed: German translation of “The New Tau”. Done more effort on reach out to potential tribe channels: Research groups, LinkedIn groups, Facebook groups. Most represented keywords: Complex Adaptive Systems, NLP, Computational Linguistics. Usual feedback: Likes but no further interaction. Created an FAQ answering all possible questions surrounding IDNI, Tau & Agoras Idea: Hosting a virtual panel to spread the word about our project among the scientific community, as well as to create some visual content for our community. Two professors are interested in participating, one from Argentina with a focus in semantic parsing, the other one from the University of Washington with a focus on human-computer interaction and social computing. First step: organizing a pre-panel discussion where in 1on1 calls with the professors we get an opinion of them about what we are doing.
Andrei: Agoras Live: Implemented mail system so users now get their mails (e.g. registration email). Improved UX together with Mo’az, e.g. user profiles. Token creation for accessing calls to identify and charge users. Customized Jitsi interface to suit our needs: E.g. display of how much time passed in a call and how much it costs. Next up: Further improve UX; make sure everything works as intended.
Mo’az: Almost finished the IDNI website. Added two more pages: Events & Bounties in collaboration with Fola & Kilian. Agoras Live: Finetuned all the website’s components in collaboration with Andrei.
Juan: Continued working on the payments system for Agoras Live. Had some delays due to the complexity of debugging such applications. Still, we made significant progress and got the funding transactions implemented over the Lightning network through the Omni layer. Spent time analyzing the minimum amount of BTC to pay for the fees associated to the Omni transactions. We aren’t using segregated witness native addresses and instead are using embedded segregated witness. So transaction sizes are enlarged and transaction fees are a bit higher. So there is a bit of finetuning analysis needed in order to enable the multisig address to pay for the closing & refund transactions. So to provide payment channels over the Omni layer, the main remaining technical detail we have to solve at this point is the closing transaction & the refund transaction.
Fola: Have been continuing to look for great talent in different areas. Continued working on website with Mo’az and Kilian. Been working on the branding for Tau & Agoras. Been getting external support to make sure the branding for Tau & Agoras will be as professional as it can be. Working on marketing efforts needed for the release of Agoras Live to get the media pack for marketing ready. Working together with external people to put a plan together for listing the Agoras token on more prominent exchanges as we get closer to release of Agoras Live.
Ohad: Continued working on restricted versions of second-order logic to understand how to implement them. There is a translation in the literature about how to convert second-order logic by Horn into Datalog. Also, I have been revisiting papers that deal with descriptive complexity of higher-order logic. They mention that they have a translation from second-order logic to QBF. I wasn’t able to find where they explain this translation but I wrote one of them and he said he will send me the paper. If so, that will be very good because we already have a QBF solver. Any binary decision diagram is already a QBF solver, so we can just translate arbitrary second-order logic formulas into QBF. This will be very helpful for us to implement second-order logic. Also, those papers mention several aspects that are relevant for self-interpretation, the laws of laws. Apparently, they suggest that certain fragments of higher-order logic may also support the laws of laws. But this is part of the papers that I didn’t have access to, so I have to wait to get further clarification. I also pushed the whitepaper significantly this month and hope we will be finishing it soon. Also, I was thinking about some optimizations for the parser and also was looking into the Lightning network. It was my mistake that I haven’t done so beforehand and if I had done it beforehand, I would have understood earlier, that Lightning is too much. It is too drastic of a change to how traditional payments work and there apparently is no reason to believe that it is secure. So I’m glad I discovered better now than later that it’s not something we’d like to rely on, although we can have it as an optional feature.
Q&A:
Q: With the project development taking longer than other projects such as Tezos, when can AGRS holders expect something to be released and, how can you reassure us that we made the right decision?
A: With regards to when we see some releases, it seems that we will see some releases in 2020. For comparing to Ethereum and Tezos: Let’s first talk about funding. Both projects had a lot of money. For Ethereum, the reason for is that it has probably done one of the most aggressive marketing campaigns in history. It was completely lacking any kind of honesty. It was simply aggressive. None of Ethereum’s visions and promises became true. It simply became an insecure platform for scams. None of their vision of creating a world computer, of creating a better society, a better currency, became true. Because of this aggressive marketing, they not only raised a lot of money, they also took the price to be so high in the market. If you remember the campaign of the flipping, they did a whole campaign on how they would overtake the marketcap of Bitcoin. For Tezos, they made maybe the largest ICO in history in terms of money, mainly because they came at the right time, at the top of the bubble in 2017, and also their promises for better coordination didn’t come true. Their solution is based on voting and based on Turing completeness and the only reason why they managed to gain such a market cap as of today, is not because they offer better currency, better society, better anything. It basically is a Ponzi-scheme because they offer very high interest rate by very high inflation (5,51%). The only reason why people buy Tezos is to get into this Ponzi-scheme. Because both Tezos and Ethereum lack any true economical or technological substance, their value will not sustain and this is true for almost all projects in the cryptocurrency world. In the software, high-tech market, if you come up with good tech and you do all the right things, you succeed big time. But if you don’t have it and you are purely relying on brainwashing people, it will not sustain. Of course, our solution is so disruptive and sustainable. We offer to do advancements for humanity and for economy.
Q: What three subjects would you first like to see discussed on Tau?
A: Of course, picking three subjects now is a bit speculative, but the first thing that comes to mind is the definitions of what good and bad means and what better and worse means. The second subject is the governance model over Tau. The third one is the specification of Tau itself and how to make it grow and evolve even more to suit wider audiences. The whole point of Tau is people collaborating in order to define Tau itself and to improve it over time, so it will improve up to infinity. This is the main thing, especially initially, that the Tau developers (or rather users) advance the platform more and more.
Q: What is stopping programmers using TML right now? If nothing, what is your opinion on why they aren’t?
A: There is nothing essentially missing in TML in order to let it release. And in fact, we are now working towards packaging it and bringing it towards a release level. For things like documentation, bug fixes, minor features, minor optimizations. We indeed actively work towards releasing TML 1.0 and then we can publish it in e.g. developers channels for them to use it.

READ: TERN - Massive upside potential - Ternio Cryptocurrency On BlockCard

TERN: Ternio’s own cryptocurrency that is based on the Stellar blockchain. It is a perfect value exchange for instant peer to peer micropayments and often confirms transactions in under 5 seconds for fractions of a penny. TERN can be exchanged peer to peer with any wallet that supports Stellar based assets, but is given even utility as the payment token used on all Ternio products including Lexicon and BlockCard.
Use Case: TERN is Ternio’s own digital currency and is the payment token used on all Ternio products. Every BlockCard uses TERN as the default spendable asset. All non-TERN deposits such as Bitcoin are converted to TERN when deposited in the BlockCard dashboard. The value of TERN is tied to usage of the BlockCard ecosystem. As users deposit on BlockCard, the value of TERN increases. As people spend, the value decreases. We have worked hard to build utility of TERN into the functionality of BlockCard. Live VISA Debit card with 6.38% crypto back on all spend.

FLETA Collaborates With Other Projects

FLETA Collaborates With Other Projects
https://preview.redd.it/o1586ny7eo351.png?width=1400&format=png&auto=webp&s=e5afa3e84fe962b1ecabdd4600e824daca1c9651
Decentralized blockchain projects are gaining more and more popularity each day as the world realizes the potential of this blockchain technology. FLETA has decided to cooperate with other projects to drive the adoption of blockchain technology, facilitate technological innovations, and expand its network. In this article, we will introduce FLETA and other blockchain projects collaborating with us.

FLETA

FLETA is a blockchain platform for decentralized applications aimed at solving some of the blockchain’s biggest hurdles. They have made advances to solve the scalability issues, but still keeping the blockchain fast and decentralized through a unique consensus algorithm known as Proof-of-Formulation.
Formulators are the key to FLETA’s technology. They are the block generators who mine and create new blocks. The mining process is configured in such a fair way that every formulator will get a chance to generate a block. This prevents conflicts and abuse because every miner is equal.
Generated blocks are confirmed and signed in real-time by Observer Nodes. They are responsible for securing the network, preventing DDOS attacks, and making forks impossible. Forks cannot happen on FLETA because 3 out of 5 Observers are required to sign and confirm the block. The first block with 3 signatures is the only valid one.
Proof-of-Formulation has been tested and verified in real-life scenarios. It is capable of achieving 14,000 transactions but remains highly secure due to the exclusive connection between Formulators and node Observers.

Matic Network

The Matic Network hopes to improve the scalability of Ethereum, by using PoS side chains, but without losing the critical elements of decentralization.
Matic’s multiple side chains possibly scale to millions of transactions each second in the future. The transaction fees are inexpensive, and its Plasma framework results in new blocks being generated in less than 2 seconds. It makes Matic a well-suited platform for micropayments.
FLETA is using Matic’s Plasma framework solutions on its Mainnet. FLETA has an auto-swap feature between the FLETA ERC-20 token and its native FLETA coin. The two projects have cooperated to improve the Deposit & Withdrawal options on FLETA and making them more decentralized.

TomoChain

TomoChain is a blockchain platform that uses a Proof-of-Stake Voting Consensus to combat scalability. It is based on a network of 150 Masternodes. This technology allows a network throughput of 2,000 transactions per second and a 2 seconds blocktime.
TomoChain can be used by developers to build their own DApps. Also, by taking advantage of the TomoX Protocol, they can launch a decentralized exchange. The TomoP Protocol is a privacy feature allowing anonymous transactions. When enabled, it conceals information about the transacting parties, used addresses, and transaction amounts.
FLETA and TomoChain have signed a technical agreement that foresees the use of the TomoZ Protocol that allows fees to be paid with different tokens. FLETA will be creating a FLETA Token that can provide broader use cases within the TomoChain ecosystem.

Neo

Neo is an open-source blockchain platform that uses smart contracts to digitize assets. The ownership of physical items from the real world can be registered, traded, and transferred via the Neo blockchain. Neo is a strong development platform that supports multiple coding languages and has an experienced development community.
FLETA and Neo have signed a strategic partnership, which entails the use of NeoVM on FLETA’s Mainnet. NeoVM is a lightweight and scalable virtual machine for smart-contract development. With its cross-platform compatibility, FLETA will significantly benefit from it.
Once deployed, FLETA and Neo will cooperate on several projects. The first planned one is a blockchain-based Real World Data-based Clinical Research Data Registry Platform for the medical industry. The project aims to activate medical data research and help researchers efficiently use the data.

Wanchain

Wanchain is a cross-chain compatible infrastructure that seeks to connect the world of decentralized finance into one interoperable ecosystem. Different blockchain systems are incompatible with each other, and they operate on their own. The answer to this is creating wrapped tokens of the original assets and incorporating them on the Wanchain platform.
It allows the coins to be used in ways that weren’t possible before. For example, a wrapped Bitcoin token can be used in an Ethereum smart contract to take advantage of the Ethereum blockchain. The token can be easily exchanged back to real Bitcoin by using Wanchain technology.
Wanchain is based on the codebase of Ethereum, but it uses a PoS consensus algorithm. The project has established a partnership with FLETA. With this understanding, both companies expect further to improve interoperability and the performance of their systems.

WINk

WINk is a gaming platform offering Live Casino Games, virtual sports, Slots, and E-gaming. WINk was previously known as TronBet, and it is located on the TRON Mainnet.
The platform supports several different tokens: TRX, Dice, USDT, BTT, and of course, WIN token. Besides being a gaming community, WINk also features a staking option. By staking WIN tokens, users get the chance to earn daily staking rewards from the platform’s profits.
WINk plans to integrate with Wallet Street, the social data platform of FLETA. Wallet Street allows stakeholders to communicate and create online communities. The two platforms will start a joint marketing campaign. Wallet Street allows its users to build their own buildings based on the number of coins they own. These structures become visible on a virtual map on Wallet Street. A WINk building will be constructed on Wallet Street’s map to advertise WINk project and its token.

Conclusion

Cooperation is essential for the crypto industry as it opens new possibilities. The sharing of information and knowledge is beneficial to success. Entering new markets allows companies to expand their user base. A broader reach increases use cases for blockchain technology and achieve the ultimate goal: massive adoption. FLETA has realized the importance of strong partnerships, and during 2020, their services will be taken to a whole new stage.

An Insight Into Bitcoin Improvement Proposal (BIP)

While Bitcoin is the most famous and valuable cryptocurrency, its blockchain faces some challenges. In order to ensure the constant dominance of the currency in the market, the Bitcoin Improvement Proposal (BIP) was introduced. While most BIPs have different levels of potential for positive impact on Bitcoin blockchain, some of them turned out to be much more successful than others.

What is BIP?

Bitcoin is considered the first cryptocurrency and still remains the most successful crypto-project, but it also has its drawbacks. And in order to surpass it, as well as to occupy its niche in the digital world, innovators have created many new currencies, each of which has its own blockchain, designed to provide functions that are not available in Bitcoin. Eventually, one of these new currencies could potentially knock Bitcoin out of the first place.
That’s why the work on the Bitcoin Improvement Proposal began. BIP is a document where developers can submit a recommendation to fix a network problem. For example, after the introduction and implementation of BIP 141, also known as Segregated Witness (SegWit), the transaction rate on the Bitcoin network has increased, and commission fees have significantly decreased.
There are three varieties of BIP:

Bitcoin Lightning Network

The Lightning Network is a BIP proposal introduced in 2015 by Joseph Poon and Thaddeus Dryja. It aims to make Bitcoin scalable with the help of instant payments that are performed outside the network. These external channels form real Bitcoin transactions with the use of standard scripts that allow transferring funds without risk.
The Lightning network came into force thanks to the introduction of wallets with many signatures, where the parties can conduct an infinite number of transactions without having to store all the details on the blockchain. The only information recorded on the blockchain is the number of Bitcoins contained in the wallet and the percentage of contributions of the parties involved.
In addition to enabling instant transactions, the update also provides other benefits for the Bitcoin chain. For example, registration for micropayments, as well as cross-chain payments. Moreover, the update also promotes the implementation of the functionality of smart contracts on top of the blockchain.

MAST technology

MAST stands for Merkelized Abstract Syntax Tree, a technology that uses the ideas of the Merkle tree and the abstract syntax tree. This is a cryptographic tool that allows you to add large volumes of the hash to the data associated with transactions in the Bitcoin chain, due to their layout.
Three BIPs aim to introduce MAST into the Bitcoin network. The first is BIP 114, created by Johnson Lau, the developer of the Bitcoin core. The proposal shows how to increase network efficiency by introducing a new scenario, which he calls a merkelized scenario. The scenario reduces the need for large amounts of transaction data while maintaining greater privacy.
BIP 116 and BIP 117 were proposed by Bitcoin Core developer Mark Friedenbach and are intended to support MAST in a joint implementation. In BIP 116, he outlines the operation code, which allowed validation of the data without revealing the entire set. BIP 117 is called the Tail Call semantics, and in combination with the first, it led to a generalized form of MAST. The difference between the offers of Friedenbach and Lau is that the first supports all the scenarios that are currently used on the Bitcoin network, and the second supports only native SegWit.
The introduction of MAST has led to increased privacy, increased transaction speed, and the ability to include complex data sets, such as smart contracts. Besides, MAST allowed the Bitcoin network to process a much larger volume of transactions and, thereby, increased its scalability.

How many BIPs are there?

Since absolutely any developer can submit the idea of improving the network to the community, more than 300 of these ideas have already been accumulated, and not all of them have been and will be implemented in Bitcoin.

An Insight Into Bitcoin Improvement Proposal (BIP)

While Bitcoin is the most famous and valuable cryptocurrency, its blockchain faces some challenges. In order to ensure the constant dominance of the currency in the market, the Bitcoin Improvement Proposal (BIP) was introduced. While most BIPs have different levels of potential for positive impact on Bitcoin blockchain, some of them turned out to be much more successful than others.

What is BIP?

Bitcoin is considered the first cryptocurrency and still remains the most successful crypto-project, but it also has its drawbacks. And in order to surpass it, as well as to occupy its niche in the digital world, innovators have created many new currencies, each of which has its own blockchain, designed to provide functions that are not available in Bitcoin. Eventually, one of these new currencies could potentially knock Bitcoin out of the first place.
That’s why the work on the Bitcoin Improvement Proposal began. BIP is a document where developers can submit a recommendation to fix a network problem. For example, after the introduction and implementation of BIP 141, also known as Segregated Witness (SegWit), the transaction rate on the Bitcoin network has increased, and commission fees have significantly decreased.
There are three varieties of BIP:

Bitcoin Lightning Network

The Lightning Network is a BIP proposal introduced in 2015 by Joseph Poon and Thaddeus Dryja. It aims to make Bitcoin scalable with the help of instant payments that are performed outside the network. These external channels form real Bitcoin transactions with the use of standard scripts that allow transferring funds without risk.
The Lightning network came into force thanks to the introduction of wallets with many signatures, where the parties can conduct an infinite number of transactions without having to store all the details on the blockchain. The only information recorded on the blockchain is the number of Bitcoins contained in the wallet and the percentage of contributions of the parties involved.
In addition to enabling instant transactions, the update also provides other benefits for the Bitcoin chain. For example, registration for micropayments, as well as cross-chain payments. Moreover, the update also promotes the implementation of the functionality of smart contracts on top of the blockchain.

MAST technology

MAST stands for Merkelized Abstract Syntax Tree, a technology that uses the ideas of the Merkle tree and the abstract syntax tree. This is a cryptographic tool that allows you to add large volumes of the hash to the data associated with transactions in the Bitcoin chain, due to their layout.
Three BIPs aim to introduce MAST into the Bitcoin network. The first is BIP 114, created by Johnson Lau, the developer of the Bitcoin core. The proposal shows how to increase network efficiency by introducing a new scenario, which he calls a merkelized scenario. The scenario reduces the need for large amounts of transaction data while maintaining greater privacy.
BIP 116 and BIP 117 were proposed by Bitcoin Core developer Mark Friedenbach and are intended to support MAST in a joint implementation. In BIP 116, he outlines the operation code, which allowed validation of the data without revealing the entire set. BIP 117 is called the Tail Call semantics, and in combination with the first, it led to a generalized form of MAST. The difference between the offers of Friedenbach and Lau is that the first supports all the scenarios that are currently used on the Bitcoin network, and the second supports only native SegWit.
The introduction of MAST has led to increased privacy, increased transaction speed, and the ability to include complex data sets, such as smart contracts. Besides, MAST allowed the Bitcoin network to process a much larger volume of transactions and, thereby, increased its scalability.

How many BIPs are there?

Since absolutely any developer can submit the idea of improving the network to the community, more than 300 of these ideas have already been accumulated, and not all of them have been and will be implemented in Bitcoin.

Today I was banned from r / Bitcoin for showing that BCH can be more secure than BTC for micropayment transactions.

Yesterday I posted a video on r / Bitcoin, where I perform a double spend attack using a BTC wallet with RBF. In order to educate people not to conduct transactions with zero confirmation. In the same video I demonstrate that the attack does not work with BCH, so I just suggested that for micropayment transactions, which in general cannot be expected for the first acknowledgment to occur, they should give preference to BCH. For micropayments BTC offers a great risk to the merchant. Only that… Everyone knows that the BTC is not for micropayments something that was commented on by a Bitcoin member. And that risk would represent a tiny slice of the market. While we actually know the importance of micropayments for the sustainability of cryptocurrencies, the greatest proof of this is the effort made by the BTC community to develop LN. I in one of the comments explained that putting all the chips in LN is very risky, when there are already coins that make micropayments safely. It is just my humble opinion. Well, I think they can't stand criticism. I consider that all my criticisms were important to the BTC. For we are talking about a real possibility of attack that can be made by anyone. I repeat! Anyone can do! Quite simply by using, for example, a cell phone, if one cannot wait for a confirmation at least. What really makes BTC bad for micropayments! The comments I wanted would be; Let's look at this, or unfortunately we'll wait for LN, because we don't think micropayments are important right now, or we'll make users aware of this risk, but no, they banned me! In a free economy and society, competition and criticism are of the utmost importance for the evolution of systems; it is important to be tolerant, to live with divergent thoughts. They banned a critical idea from their group, hardly knowing that they lost more than they gained. My ban: https://imgur.com/gallery/P13iVpz

Best Bitcoin Faucets

Best Bitcoin Faucets
Bitcoin faucets are websites or applications that offer you a small amount of bitcoin as a reward for making easy tasks. Depending on the selected faucet, users can earn coins for completing various tasks, such as viewing certain websites, watching ads, entering a captcha, or playing a game.
by StealthEX
At the beginning of the cryptocurrency’s existence, when the stakes were not so high, the creators of faucets gave 5 bitcoins for each claim — back then it was their way to promote digital money among newcomers. Now faucets operate with much smaller amounts and give out some part of the Bitcoin, which is measured in Satoshi(named after the creator of Bitcoin). Satoshi is the smallest possible fractional number of Bitcoin — one BTC is equal to 100 million Satoshi.
If you have ever left a water tap not completely closed, you probably noticed that water was dripping into it, and if you put a bowl under it, sooner or later it will be filled. Even though one-time payments on faucets are scanty, many advise not to neglect the opportunity to earn on them, because, with the right approach, faucets can bring a tangible profit with a minimum of effort.
There are plenty of sites offering free bitcoins. Unfortunately, most of them are not trustworthy, do not live long, or are simply overflowed with annoying flashing ads. However, there are some that work for many years, used by thousands of users and considered reliable.
Here is the list of them:

Freebitcoin

This faucet is probably the most well-known one. It was created in 2013 on the territory of the British Virgin Islands. Payouts are not fixed and vary for each claim. You can get cryptocurrency every hour, and for each claim you get from 0.00000030 to 0.03 BTC. In addition to the faucet, Freebitcoin allows you to earn in other ways — save interest on your deposit, play the lottery, invite new users via referral links.
It supports several withdrawal methods: you can set up automatic withdrawal every Sunday, slow withdrawal every 6–24 hours, or use the fastest instant withdrawal that takes 15 minutes. The last one, of course, has the highest fee.

Moon Bitcoin

Founded in 2015, the Moon Bitcoin has a certain user base and is considered by many to be one of the best faucets in existence.
There are many appealing bonus offers. For example, the site gives you a reward for consistency — if you enter a captcha at least once every day, you will accumulate a bonus +1% to earnings daily. Like most other faucets, Moon Bitcoin offers a bonus for bringing new users.
Earned funds are instantly transferred to the linked Coinpot wallet. The minimum withdrawal amount is 10,000 Satoshi if you agree to pay the fee. Or wait until it’s going to be over 50,000 Satoshi on your account and withdrawal money for free. It is worth saying that Coinpot has its own bonus program. For example, for one captcha entry, you get 3 Coinpot tokens that can also be converted to cryptocurrency.
There are also Moon faucets for Litecoin, Dash, Bitcoin Cash and DogeCoin. All payments are concentrated in one Coinpot account.

Bonus Bitcoin

Bonus Bitcoin is one of the oldest services and is considered one of the best bitcoin faucets. You can request a new portion of free coins every 15 minutes, getting an average of 10 Satoshi per claim. You can also gain more coins completing tasks in the offers and surveys section.
Users who regularly stay active for a number of days receive an additional 5% of their daily rewards. The site also gives 50% of all fees of users you invited using referral links.
Bonus Bitcoin accounts are also connected to Coinpot, a micro-earnings wallet that accumulates your payouts. The site also provides the opportunity to earn Litecoin and Dogecoin.

Bitfun

This is one more faucet associated with Coinpot wallet. Bitfun started its work in January 2017. In addition to the faucet itself, which allows you to request free Satoshi every 3 minutes, the site has a large number of browser games of various genres. Progress in these games gives you additional earnings. You can also earn coins by completing offers.
As with Bonus Bitcoin, the user receives 50% of the fees of their referrals.

Cointiply

The service was launched in 2018 and has become known as one of the best free bitcoin generators. There are several ways to claim Satoshi. In addition to the faucet, you can also earn bitcoins by watching videos, clicking on ads, and playing browser games.
Here you can make claims once every 12 hours and get a certain number of Coins to your account. Coins are the inner currency of this service, 10000 Coins worth 1$. It converted to Satoshi at the time of withdrawal.
Rewards can be collected at FaucetHub, another web wallet for micropayments, in this case, the withdrawal limit is 35,000 Coins. For amounts over 100,000 Coins, withdrawals can be made directly to your bitcoin wallet. Or you can keep Coins at the site and earn 5% interest.
Users can earn a loyalty bonus, by claiming rewards every day. Bringing another user via referral link gives you 25% of their claims and 10% of their offer earnings.

Pentafaucet

PentaFaucet is one of the oldest and most stable bitcoin faucets today. The main difference from similar websites is that the site uses double protection: captcha and anti-bot. You can collect from 5 to 25 Satoshi every 5 minutes. A reasonable amount of advertising and a simple interface make working with the faucet comfortable.
The faucet does not allow you to earn money from games, surveys, and other sponsorship services. In addition to the main method, it offers only a referral program, giving 10% from earnings of each new user.
Earned Satoshi are instantly transferred to the FaucetHub wallet. You can withdraw your funds from FaucetHub to your bitcoin wallet once a week on Sundays.

FireFaucet

FireFaucet is a multi-currency automatic faucet, perhaps the best of its kind. This resource allows you to earn 9 cryptocurrencies at the same time, as well as instantly withdraw the accumulated funds to the Faucet Hub.
The Auto Claim function allows for collecting currency automatically. You can change the number of currencies to get and the time between collections.
FireFaucet affords many different ways to earn money: in addition to the faucet itself, there are also offers, a referral system that gives 20% from newcomer’s income, and browser mining. FireFaucet also has its own unique level system: getting XP for various actions on the site and raising their level, users receive a reward in Satoshi.
As a pleasant addition, FireFaucet has a nice-looking design and does not use pop-up ads.

DailyFreeBits

This bitcoin faucet does not require registration. All you need is the public address of your BTC wallet. Users can claim Satoshi every hour, getting from 5 to 1200 each time.
At the moment DailyFreeBits is using the FaucetHub wallet we are already familiar with. The resource offers a referral reward. By inviting new users to the website, you can regularly receive 10% of their earnings.
These are probably the best bitcoin faucets at this point. Do not expect that you will earn loads of money just using faucets, but it is with no doubt an interesting and easy way to get a certain portion of free Satoshi and learn how the cryptocurrency and various wallets work.
Always be careful and study every site that is claimed to be a Bitcoin faucet with some scepticism. Always be critical of your choice and read reviews.

How long with the Stellar consolidation last? A forecast from the XLMwallet

How long with the Stellar consolidation last? A forecast from the XLMwallet
It’s been three weeks since the Bitcoin halving, but the rally so many were waiting for didn’t happen, at least for now. Stellar is consolidating and seems to be going up. When can you expect significant gains? As always XLMwallet analytics offer a forecast.
Stellar is still trying to recover from the big hit it took on May 10, together with Bitcoin and the rest. It went from $0.072 to $0.064 — a 12% fall. It scrapped a lot of the gains made in the previous month.

https://xlmwallet.co/
What happened? Why did XLM fall so much? Don’t panic — and definitely don’t sell. If you hold lumens in your XLMwallet, continue to do so. (We hope you do, because XLMwallet is awesome.)
What happened was a banal Bitcoin liquidation. Just before the halving, there was lots of volatility in the market, with people getting excited. The price started rising and even tried to go beyond $10,000. For Bitcoin, it’s been a very strong level or resistance since last summer.
When the price couldn’t cross the $10k mark, it became clear that the ceiling is reached for now. And people started to sell. The price began to fall. Then, a massive liquidation of short positions followed. Those are the futures positions on exchanges like BitMex: a lot of people were shorting BTC. Once some of the positions automatically closed, the price fell a bit further, more positions were liquidated, the price fell again, and so on. It was a chain reaction. Nothing happened to Bitcoin, nothing happened to Stellar. It was all just a technical process.
Stellar, Ethereum and the others simply followed. That’s the unfortunate reality of crypto: all the altcoins follow BTC, like sheep follow a dog. Bitcoin has been struggling to grow back ever since, and so is Stellar. In addition, there are a lot of Bitcoin miners selling the BTC they accumulated in the past few months, creating additional downward pressure.
What should you do? As we’ve said, definitely not sell. It will take Bitcoin a couple of months to get out of its consolidation stage, and then it can start growing properly, tagging the rest of the coins along. We expect very good gains for Stellar starting from July — definitely higher than where it was in early May.
Moreover, the Stellar Foundation has just made another investment. It gave $550,000 to a startup called SatoshiPay. It’s a micropayments product that is now eyeing an expansion into the B2B territory, mostly to let creators of online content get paid across borders.
As we all know, Stellar is the perfect cryptocurrency for cross-border payments: it’s extremely fast and cheap. As we always say, if you can HODL your lumens in the XLMwallet, do so. But if you have to pay with crypto somewhere, do it with Stellar rather than in BTC. Especially now, after the halving, when the BTC transaction fee has risen above $3 — many thousands of times more than with XLM!
In a few words: our advice for XLM owners is hold. A rally is coming, though we’ll have to wait a couple of months for it. We’re pretty sure that the worst for Stellar is over this year, and the only way to go is up.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.
  • Bitcoin (BTC) is a peer-to-peer cryptocurrency that aims to function as a means of exchange that is independent of any central authority. BTC can be transferred electronically in a secure, verifiable, and immutable way.
  • Launched in 2009, BTC is the first virtual currency to solve the double-spending issue by timestamping transactions before broadcasting them to all of the nodes in the Bitcoin network. The Bitcoin Protocol offered a solution to the Byzantine Generals’ Problem with a blockchain network structure, a notion first created by Stuart Haber and W. Scott Stornetta in 1991.
  • Bitcoin’s whitepaper was published pseudonymously in 2008 by an individual, or a group, with the pseudonym “Satoshi Nakamoto”, whose underlying identity has still not been verified.
  • The Bitcoin protocol uses an SHA-256d-based Proof-of-Work (PoW) algorithm to reach network consensus. Its network has a target block time of 10 minutes and a maximum supply of 21 million tokens, with a decaying token emission rate. To prevent fluctuation of the block time, the network’s block difficulty is re-adjusted through an algorithm based on the past 2016 block times.
  • With a block size limit capped at 1 megabyte, the Bitcoin Protocol has supported both the Lightning Network, a second-layer infrastructure for payment channels, and Segregated Witness, a soft-fork to increase the number of transactions on a block, as solutions to network scalability.

1. What is Bitcoin (BTC)?

  • Bitcoin is a peer-to-peer cryptocurrency that aims to function as a means of exchange and is independent of any central authority. Bitcoins are transferred electronically in a secure, verifiable, and immutable way.
  • Network validators, whom are often referred to as miners, participate in the SHA-256d-based Proof-of-Work consensus mechanism to determine the next global state of the blockchain.
  • The Bitcoin protocol has a target block time of 10 minutes, and a maximum supply of 21 million tokens. The only way new bitcoins can be produced is when a block producer generates a new valid block.
  • The protocol has a token emission rate that halves every 210,000 blocks, or approximately every 4 years.
  • Unlike public blockchain infrastructures supporting the development of decentralized applications (Ethereum), the Bitcoin protocol is primarily used only for payments, and has only very limited support for smart contract-like functionalities (Bitcoin “Script” is mostly used to create certain conditions before bitcoins are used to be spent).

2. Bitcoin’s core features

For a more beginner’s introduction to Bitcoin, please visit Binance Academy’s guide to Bitcoin.

Unspent Transaction Output (UTXO) model

A UTXO transaction works like cash payment between two parties: Alice gives money to Bob and receives change (i.e., unspent amount). In comparison, blockchains like Ethereum rely on the account model.
https://preview.redd.it/t1j6anf8f3151.png?width=1601&format=png&auto=webp&s=33bd141d8f2136a6f32739c8cdc7aae2e04cbc47

Nakamoto consensus

In the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW).
The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer.
Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer CPUs.
As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit (“ASIC”).
Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so.
With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network’s hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic.
Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.

The blockchain

Block production

The Bitcoin protocol utilizes the Merkle tree data structure in order to organize hashes of numerous individual transactions into each block. This concept is named after Ralph Merkle, who patented it in 1979.
With the use of a Merkle tree, though each block might contain thousands of transactions, it will have the ability to combine all of their hashes and condense them into one, allowing efficient and secure verification of this group of transactions. This single hash called is a Merkle root, which is stored in the Block Header of a block. The Block Header also stores other meta information of a block, such as a hash of the previous Block Header, which enables blocks to be associated in a chain-like structure (hence the name “blockchain”).
An illustration of block production in the Bitcoin Protocol is demonstrated below.

https://preview.redd.it/m6texxicf3151.png?width=1591&format=png&auto=webp&s=f4253304912ed8370948b9c524e08fef28f1c78d

Block time and mining difficulty

Block time is the period required to create the next block in a network. As mentioned above, the node who solves the computationally intensive task will be allowed to produce the next block. Therefore, block time is directly correlated to the amount of time it takes for a node to find a solution to the task. The Bitcoin protocol sets a target block time of 10 minutes, and attempts to achieve this by introducing a variable named mining difficulty.
Mining difficulty refers to how difficult it is for the node to solve the computationally intensive task. If the network sets a high difficulty for the task, while miners have low computational power, which is often referred to as “hashrate”, it would statistically take longer for the nodes to get an answer for the task. If the difficulty is low, but miners have rather strong computational power, statistically, some nodes will be able to solve the task quickly.
Therefore, the 10 minute target block time is achieved by constantly and automatically adjusting the mining difficulty according to how much computational power there is amongst the nodes. The average block time of the network is evaluated after a certain number of blocks, and if it is greater than the expected block time, the difficulty level will decrease; if it is less than the expected block time, the difficulty level will increase.

What are orphan blocks?

In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producingorphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency.
It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency.
Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted.
The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network.
However, given a limited amount of transactions that can be stored in a block, making the block time too longwould decrease the number of transactions the network can process per second, negatively affecting network scalability.

3. Bitcoin’s additional features

Segregated Witness (SegWit)

Segregated Witness, often abbreviated as SegWit, is a protocol upgrade proposal that went live in August 2017.
SegWit separates witness signatures from transaction-related data. Witness signatures in legacy Bitcoin blocks often take more than 50% of the block size. By removing witness signatures from the transaction block, this protocol upgrade effectively increases the number of transactions that can be stored in a single block, enabling the network to handle more transactions per second. As a result, SegWit increases the scalability of Nakamoto consensus-based blockchain networks like Bitcoin and Litecoin.
SegWit also makes transactions cheaper. Since transaction fees are derived from how much data is being processed by the block producer, the more transactions that can be stored in a 1MB block, the cheaper individual transactions become.
https://preview.redd.it/depya70mf3151.png?width=1601&format=png&auto=webp&s=a6499aa2131fbf347f8ffd812930b2f7d66be48e
The legacy Bitcoin block has a block size limit of 1 megabyte, and any change on the block size would require a network hard-fork. On August 1st 2017, the first hard-fork occurred, leading to the creation of Bitcoin Cash (“BCH”), which introduced an 8 megabyte block size limit.
Conversely, Segregated Witness was a soft-fork: it never changed the transaction block size limit of the network. Instead, it added an extended block with an upper limit of 3 megabytes, which contains solely witness signatures, to the 1 megabyte block that contains only transaction data. This new block type can be processed even by nodes that have not completed the SegWit protocol upgrade.
Furthermore, the separation of witness signatures from transaction data solves the malleability issue with the original Bitcoin protocol. Without Segregated Witness, these signatures could be altered before the block is validated by miners. Indeed, alterations can be done in such a way that if the system does a mathematical check, the signature would still be valid. However, since the values in the signature are changed, the two signatures would create vastly different hash values.
For instance, if a witness signature states “6,” it has a mathematical value of 6, and would create a hash value of 12345. However, if the witness signature were changed to “06”, it would maintain a mathematical value of 6 while creating a (faulty) hash value of 67890.
Since the mathematical values are the same, the altered signature remains a valid signature. This would create a bookkeeping issue, as transactions in Nakamoto consensus-based blockchain networks are documented with these hash values, or transaction IDs. Effectively, one can alter a transaction ID to a new one, and the new ID can still be valid.
This can create many issues, as illustrated in the below example:
  1. Alice sends Bob 1 BTC, and Bob sends Merchant Carol this 1 BTC for some goods.
  2. Bob sends Carols this 1 BTC, while the transaction from Alice to Bob is not yet validated. Carol sees this incoming transaction of 1 BTC to him, and immediately ships goods to B.
  3. At the moment, the transaction from Alice to Bob is still not confirmed by the network, and Bob can change the witness signature, therefore changing this transaction ID from 12345 to 67890.
  4. Now Carol will not receive his 1 BTC, as the network looks for transaction 12345 to ensure that Bob’s wallet balance is valid.
  5. As this particular transaction ID changed from 12345 to 67890, the transaction from Bob to Carol will fail, and Bob will get his goods while still holding his BTC.
With the Segregated Witness upgrade, such instances can not happen again. This is because the witness signatures are moved outside of the transaction block into an extended block, and altering the witness signature won’t affect the transaction ID.
Since the transaction malleability issue is fixed, Segregated Witness also enables the proper functioning of second-layer scalability solutions on the Bitcoin protocol, such as the Lightning Network.

Lightning Network

Lightning Network is a second-layer micropayment solution for scalability.
Specifically, Lightning Network aims to enable near-instant and low-cost payments between merchants and customers that wish to use bitcoins.
Lightning Network was conceptualized in a whitepaper by Joseph Poon and Thaddeus Dryja in 2015. Since then, it has been implemented by multiple companies. The most prominent of them include Blockstream, Lightning Labs, and ACINQ.
A list of curated resources relevant to Lightning Network can be found here.
In the Lightning Network, if a customer wishes to transact with a merchant, both of them need to open a payment channel, which operates off the Bitcoin blockchain (i.e., off-chain vs. on-chain). None of the transaction details from this payment channel are recorded on the blockchain, and only when the channel is closed will the end result of both party’s wallet balances be updated to the blockchain. The blockchain only serves as a settlement layer for Lightning transactions.
Since all transactions done via the payment channel are conducted independently of the Nakamoto consensus, both parties involved in transactions do not need to wait for network confirmation on transactions. Instead, transacting parties would pay transaction fees to Bitcoin miners only when they decide to close the channel.

One limitation to the Lightning Network is that it requires a person to be online to receive transactions attributing towards him. Another limitation in user experience could be that one needs to lock up some funds every time he wishes to open a payment channel, and is only able to use that fund within the channel.
However, this does not mean he needs to create new channels every time he wishes to transact with a different person on the Lightning Network. If Alice wants to send money to Carol, but they do not have a payment channel open, they can ask Bob, who has payment channels open to both Alice and Carol, to help make that transaction. Alice will be able to send funds to Bob, and Bob to Carol. Hence, the number of “payment hubs” (i.e., Bob in the previous example) correlates with both the convenience and the usability of the Lightning Network for real-world applications.

Schnorr Signature upgrade proposal

Elliptic Curve Digital Signature Algorithm (“ECDSA”) signatures are used to sign transactions on the Bitcoin blockchain.

However, many developers now advocate for replacing ECDSA with Schnorr Signature. Once Schnorr Signatures are implemented, multiple parties can collaborate in producing a signature that is valid for the sum of their public keys.
This would primarily be beneficial for network scalability. When multiple addresses were to conduct transactions to a single address, each transaction would require their own signature. With Schnorr Signature, all these signatures would be combined into one. As a result, the network would be able to store more transactions in a single block.

The reduced size in signatures implies a reduced cost on transaction fees. The group of senders can split the transaction fees for that one group signature, instead of paying for one personal signature individually.
Schnorr Signature also improves network privacy and token fungibility. A third-party observer will not be able to detect if a user is sending a multi-signature transaction, since the signature will be in the same format as a single-signature transaction.

4. Economics and supply distribution

The Bitcoin protocol utilizes the Nakamoto consensus, and nodes validate blocks via Proof-of-Work mining. The bitcoin token was not pre-mined, and has a maximum supply of 21 million. The initial reward for a block was 50 BTC per block. Block mining rewards halve every 210,000 blocks. Since the average time for block production on the blockchain is 10 minutes, it implies that the block reward halving events will approximately take place every 4 years.
As of May 12th 2020, the block mining rewards are 6.25 BTC per block. Transaction fees also represent a minor revenue stream for miners.

Nano vs. Dogecoin - a tale of two cryptocurrency for microtransactions (& more)

So, I wanted to write here, because I think Nano community is open-minded, and can think it through - I really like it, and tho I don't have it (only tested it a few times from faucets).

As I see both of those CCs are focusing mainly on low-cost payments and microtransaction/micropayments, and "fun to use".
Even tho Dogecoin can be though as "meme" and "silly", it's actually used and adopted in many places - far more then Nano (ofc, it's also older and have easier codebase to implement - sharing it with bitcoin), but as I will outline, I think that there are a few things that Nano/Nano community can learn from them.

Dogecoin:

Now Nano:

Liquidity comparison:
Nano: https://coinpaprika.com/coin/nano-nano/#!liquidity
Doge: https://coinpaprika.com/coin/doge-dogecoin/#!liquidity
The trend is evident, if you switch to 1y or max on market depth history - Dogecoin have almost +100% growth in this period (from June 2019) and Nano 50% decline.
Looking at the data from vcdepth it's even more apparent:
https://vcdepth.io/coins/doge-doge
https://vcdepth.io/coins/nano-nano

As I say, I think Nano can learn from Doge's some, especially regarding exchange's liquidity - that's preventing a lot from happening right now. Binance is the only source, and market maker for Nano, but there should be more - through the ecosystem.
What Nano team should do in my opinion is: take part of their funds from dev premine, and use it for liquidity purposes. Cryptocurrencies can't be "run" like startups, and Nano holding shouldn't be treated as equity or cash equivalent, dumping it straight on the books. Binance is making a lot to provide all of their coins with liquid markets (their MMs are one of the best on the market), but I think team can increase liquidity easily by a factor of 2-3x, just by hiring specialistic company, that will manage it. I know coins, that have done it - and it's the main thing that helped them stay relevant. Developing protocol is important, but without liquid market - it doesn't achieve anything (because it won't be used by more people). Especially I would try to improve USDT markets - they are basically USD pairs.

PS. I'm not a developer, but I research CCs on daily basis, because it's actually my work. I think my comparison is right, because Doge have achieve much more then being only "meme" currency, and Banano did not (it's only meme currency without liquidity, acceptance, or being really used anywhere).
