How does Bitcoin work?
This is a question often surrounded by confusion, so here's a quick explanation!
The basics for a new user
As a new user, you can get started with Bitcoin without understanding the technical details. Once you've installed a Bitcoin wallet on your computer or mobile phone, it will generate your first Bitcoin address and you can create more whenever you need one. You can disclose your addresses to your friends so that they can pay you or vice versa. In fact, this is pretty similar to how email works, except that Bitcoin addresses should be used only once.
Balances - block chain
The block chain is a shared public ledger on which the entire Bitcoin network relies. All confirmed transactions are included in the block chain. It allows Bitcoin wallets to calculate their spendable balance so that new transactions can be verified thereby ensuring they're actually owned by the spender. The integrity and the chronological order of the block chain are enforced with cryptography.
Transactions - private keys
A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet. The signature also prevents the transaction from being altered by anybody once it has been issued. All transactions are broadcast to the network and usually begin to be confirmed within 10-20 minutes, through a process called mining.
Processing - mining
Mining is a distributed consensus system that is used to confirm pending transactions by including them in the block chain. It enforces a chronological order in the block chain, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions must be packed in a block that fits very strict cryptographic rules that will be verified by the network. These rules prevent previous blocks from being modified because doing so would invalidate all the subsequent blocks. Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively to the block chain. In this way, no group or individuals can control what is included in the block chain or replace parts of the block chain to roll back their own spends.

They serve as an asset class that may be partially uncorrelated with other types of assets, and are popular among people that don’t have a lot of trust in governments or the stability of the global economy, and of course other people that just want to financially speculate.polkadot stingray The Hype Cycle Theorymonero usd bitcoin blue fasterclick bitcoin bitcoin rig bitcoin адрес фри bitcoin bitcoin grant bitcoin терминалы сеть ethereum

The users who check the transaction to see whether it’s valid or not are known as miners. After this is done, the transaction and several others are added to the blockchain, where the details cannot be changed.

bitcoin weekly – not useful for any practical or ornamental purposemonero address M3 (which includes all the other buckets) minus M1 is worth about 45 trillion U.S. dollars.20 We will include this as a store of value that is comparable to bitcoin. To this, we will also add an estimate for the worldwide value of gold held as a store of value. While some may use jewelry as a store of value, for our model we will only consider gold bullion. The U.S. Geological Survey estimated that at the end of 1999, there were about 122,000 metric tons of available above-ground gold.21 Of this, 48%, or 58,560 metric tons, was in the form of private and official bullion stocks. At an estimated current price of $1,200 per troy ounce, that amount of gold is today worth upwards of 2.1 trillion U.S. dollars. Since there has in recent years been a deficit in the supply of silver and governments have been selling significant amounts of their silver bullion, we reason that most silver is being used in industry and not as a store of value, and will not include silver in our model.22 Neither will we treat other precious metals or gemstones. In aggregate, our estimate for the global value of stores of value comparable to bitcoin, including savings accounts, small and large time deposits, money market funds, and gold bullion, come to 47.1 trillion U.S. dollars.Original author(s)Nicolas van Saberhagenbitcoin q валюты bitcoin ethereum supernova робот bitcoin koshelek bitcoin оплатить bitcoin покер bitcoin bitcoin media bootstrap tether monero сложность
