Even if only a single piece of information relating to any transaction is subsequently changed, for example if the amount of a transaction is altered as a result of tampering or due to transmission errors, the algorithm applied to the block will no longer produce the correct hash. The hashes computed for  1 Aug 2017 10 A 'blockchain' distributed ledger works by storing data in distinct container data structures known as 'blocks'. Each block is linked Ethereum platform cited earlier is one such example because the manner in which the smart contract code works is via 'transactions' occurring on the Ethereum blockchain can be appended transiently to the last block of the chain—a transient branching process known as a fork. Once the fork is discovered, meaning that the participants learn about its branches, the “longest” (i.e., heaviest in Ethereum or deepest in Bitcoin) branch is adopted as the valid one. Blockchain systems usually assume  coinbase eth 24 Oct 2017 That is, full nodes would only store state roots, and it would be miners' responsibility to package Merkle branches (“witnesses”) along with the blocks, and full nodes would download and verify these expanded blocks. It's entirely possible for stateless full nodes and regular full nodes to exist alongside each  (i) a blockchain instance and (ii) a blockchain security model. A blockchain instance is a PoW blockchain instantiated with a given set of consensus and network parameters, such as network delays, block generation times, block sizes, information propagation mech- anisms, etc. For example, Bitcoin, Litecoin, and Ethereum
