What is Bitcoin’s Lightning Network?
The Lightning Network is a “layer-two” network that sits on top of the Bitcoin blockchain. It allows transactions to be processed off-chain quickly and economically, thus enabling Bitcoin scalability.

Why is it needed?
Bitcoin is the world’s largest cryptocurrency, with a current market cap of over USD 600 Billion. It works as a form of decentralized digital ledger, with its transactions grouped together to form blocks. These transactions are verified by “miners” who run a network of powerful computers that compete to solve cryptographic puzzles and add the next block to the chain.
Scalability
The increasing popularity of Bitcoin led to problems dealing with the large number of transactions on the network. Due to its design, a limited number of transactions are allowed in each Bitcoin block and transactions not processed remain in a queue to be added to the next block. While traditional payments infrastructure can process thousands of transactions persecond, Bitcoin can only process 2-7 transactions/second, with a new block added every ten minutes. This leads to virtual “traffic jams” – at peak times with delays of up to a day.
Cost
Bitcoin’s proof-of-work system is also energy intensive as many miners are competing with each other simultaneously. This leads to extensive costs, which the miners offset mainly through the block reward they receive and also by collecting transaction fees. Historically, in times of peak network congestion, fees have spiked to in excess of $50.
The Lightning Network addresses these problems.
How Does Lightning Network Work?
The Lightning Network consists of channels that allows almost instantaneous transactions between participants within the system. The idea behind Lightning is that every single transaction doesn’t need to be recorded on the blockchain. Instead, only the transaction that creates the channel and the exit transaction are recorded on chain – all others are recorded in the Lightning Network.
For example, if two users want to regularly send funds to each other quickly and easily they can set up a channel by creating a multi-signature (multisig) wallet and adding funds. From then on they can carry out an unlimited amount of transactions backed by these funds. Essentially, these are off-chain transactions recorded using a type of digital ledger protected by a time clock. Both parties digitally sign and update their version after each transaction – commonly done by scanning a QR code. The actual redistribution of the original funds in the wallet only happens on the blockchain itself when the channel is closed, based on the final balance sheet.
If there is any dispute, both parties can use the most recently signed balance sheet to recover their funds, and both users have the option to unilaterally close the channel, ending their relationship. When the payment channel is closed, the updated balance is verified on the blockchain and the user can use their remaining Bitcoin again on the standard network.
This channel between the two users also forms part of a web of interconnected channels. Funds can be transferred to anyone else with a Lightning wallet, with the most economical distance between the sender and recipient decided behind the scenes by algorithms.
Pros
The instant payment, scalability and low cost gives Bitcoin more real-world uses. For example, while in the past it was impractical to use Bitcoin to buy a coffee due to high fees and delayed verification time, funds in a Lightning channel can be used as quickly as paying with a credit card.
While Bitcoin transactions currently cost around $13, transactions using the Lightning network cost around one Satoshi, equivalent to a fraction of one cent.
Lighting can be used for smaller payments – the minimum is 0.00000001 BTC, or one Satoshi.
Cons
The platform launched in 2018, so the technology and adoption is at the early stages.
Opening and closing a channel involves Bitcoin transaction fees. On a sidenote: Users looking to enter the Lightning Network may try to spot opportunistic times when Bitcoin transaction fees are low (e.g. on weekends).
Transactions can only be made when all parties involved are online.
…The MIT guy did not see any code that handled this case and asked the New Jersey guy how the problem was handled. The New Jersey guy said that the Unix folks were aware of the problem, but the solution was for the system routine to always finish, but sometimes an error code would be returned that signaled that the system routine had failed to complete its action. A correct user program, then, had to check the error code to determine whether to simply try the system routine again. The MIT guy did not like this solution because it was not the right thing… It is better to get half of the right thing available so that it spreads like a virus. Once people are hooked on it, take the time to improve it to 90% of the right thing.майнинга bitcoin bitcoin bloomberg bitcoin скачать tp tether adbc bitcoin

вывод monero a static block reward of 5 ether for the 'winning’' block (soon to be changed to 3 ether)Super secureIf Bitcoin reaches a six figure price level with 19 million coins in total, that would put its market cap at just under $2 trillion or more, above the largest mega-cap companies in the world today. It would, however, still be a small fraction of 1% of global net worth, and about a fifth of gold’s estimated market capitalization (roughly $10 trillion, back-of-the-envelope), so it’s not unfathomable for Bitcoin to eventually reach that height if there is enough sustained demand for it. During the late-2017 cryptocurrency mania, the total market capitalization of the cryptocurrency space reached over $800 billion, although as previously mentioned, Bitcoin’s share of that briefly fell to under 40% of the asset class, so it peaked at just over $300 billion.If the mining pool is successful and receives a reward, that reward is divided among participants in the pool.lamborghini bitcoin bitcoin скачать

Unfortunately, wishful thinking won’t change the properties as fundamental as the network effect or decentralization. Thousands of coins over seven years have not successfully replicated these properties and these properties are why Bitcoin is the real revolution.Bitcoin is Changing CommunicationContentsAt its most basic, a blockchain is a list of transactions that anyone can view and verify. The Bitcoin blockchain, for example, is a record of every time someone sends or receives bitcoin. This list of transactions is fundamental for most cryptocurrencies because it enables secure payments to be made between people who don’t know each other without having to go through a third-party verifier like a bank.бот bitcoin bitcoin игры bitcoin зарегистрироваться monero address elysium bitcoin спекуляция bitcoin кран bitcoin bitcoin серфинг multiply bitcoin mineable cryptocurrency

In 2013 Judge Amos L. Mazzant III of the United States District Court for the Eastern District of Texas stated that 'Bitcoin is a currency or form of money'. In July 2016, Judge Teresa Mary Pooler of Eleventh Judicial Circuit Court of Florida cleared Michell Espinoza in State of Florida v. Espinoza in money-laundering charges he faced involving his use of bitcoin. Judge Pooler stated 'Bitcoin may have some attributes in common with what we commonly refer to as money, but differ in many important aspects, they are certainly not tangible wealth and cannot be hidden under a mattress like cash and gold bars.' In September 2016, a ruling by Judge Alison J. Nathan of United States District Court for the Southern District of New York contradicted the Florida Espinoza ruling stating 'Bitcoins are funds within the plain meaning of that term.— Bitcoins can be accepted as a payment for goods and services or bought directly from an exchange with a bank account. They therefore function as pecuniary resources and are used as a medium of exchange and a means of payment.' The U.S. Treasury categorizes bitcoin as a decentralized virtual currency. The Commodity Futures Trading Commission classifies bitcoin as a commodity, and the Internal Revenue Service classifies it as an asset.ethereum сайт go bitcoin games bitcoin ico bitcoin bitcoin calc bitcoin спекуляция bitcoin goldman secp256k1 ethereum bitcoin machines monero стоимость txid ethereum bubble bitcoin bitcoin bit
