The bitcoin blockchain is a public ledger that records bitcoin transactions.[80] It is implemented as a chain of blocks, each block containing a hash of the previous block up to the genesis block[d] of the chain. A network of communicating nodes running bitcoin software maintains the blockchain.[36]:215–219 Transactions of the form payer X sends Y bitcoins to payee Z are broadcast to this network using readily available software applications.

ICO является нерегулируемым средством, с помощью которого привлекаются средства для нового предприятия в форме криптовалюты. ICO используется стартапами для обхода строгих и регулируемых процессов привлечения капитала, необходимых венчурным предпринимателям или банкам.

Bitcoin is a digital asset designed to work in peer-to-peer transactions as a currency.[4][142] Bitcoins have three qualities useful in a currency, according to The Economist in January 2015: they are "hard to earn, limited in supply and easy to verify."[143] Per some researchers, as of 2015, bitcoin functions more as a payment system than as a currency.[36]
Чтобы вернуть украденные средства, было предложено сделать откат сети путем хардфорка. Это позволило бы сделать бэкап блокчейна в начальное состояние – еще до кражи с The DAO. Полного консенсуса в сети добиться не удалось, поэтому параллельно с Ethereum появился Ethereum Classic – версия «до отката». Несмотря на то, что хардфорк позволил вернуть украденные инвестиции, его подвергли критике, так как был нарушен один из главных принципов работы блокчейн – необратимость операций.
On 3 January 2009, the bitcoin network was created when Nakamoto mined the first block of the chain, known as the genesis block.[25][26] Embedded in the coinbase of this block was the text "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks".[16] This note references a headline published by The Times and has been interpreted as both a timestamp and a comment on the instability caused by fractional-reserve banking.[27]:18

Although there are some similarities between BTC and LTC, you can’t define Litecoin without pointing out some key differences, such as instant and near-zero cost transactions, increased speed of adding a new block into the Blockchain (2.5 minutes against 10 in the Bitcoin network) and a scrypt usage in its Proof-of-Work process to make it easier for regular PC users to mine new blocks against ASIC miners. It is also one of the first cryptocurrencies that adopted SegWit.

Bitcoin is pseudonymous, meaning that funds are not tied to real-world entities but rather bitcoin addresses. Owners of bitcoin addresses are not explicitly identified, but all transactions on the blockchain are public. In addition, transactions can be linked to individuals and companies through "idioms of use" (e.g., transactions that spend coins from multiple inputs indicate that the inputs may have a common owner) and corroborating public transaction data with known information on owners of certain addresses.[126] Additionally, bitcoin exchanges, where bitcoins are traded for traditional currencies, may be required by law to collect personal information.[127] To heighten financial privacy, a new bitcoin address can be generated for each transaction.[128]
