Определения технологии блокчейн

Блокчейн — это технология надежного распределенного хранения записей обо всех когда-либо совершенных биткойн-транзакциях.


Блокчейн - Распределенный реестр, в котором нет контролирующего органа. Однажды занесенную в него информацию изменить практически невозможно.


Blockchain – A decentralized, digital ledger that records transaction information about a cryptocurrency in the chronological order.



Blockchain – (In Ethereum) a sequence of blocks validated by the proof-of-work system, each linking to its predecessor all the way to the genesis block. This varies from the Bitcoin protocol in that it does not have a block size limit; it instead uses varying gas limits.



Blockchain is a shared, immutable ledger for recording transactions, tracking assets and building trust. 



Blockchain – 1) a decentralized, publicly-owned ledger, 2)  immutable, unable to be edited, permanent, 3) maintained by remote miners all over the world.
