Ethereum: Is trimming the history of transaction implemented at the Bitcoin Satoshi client?
The original bitcoin paper by Nakamoto suggests a method of rejecting old transactions by calculating the Merle tree of the entire transaction history and storing only part of the tree. This approach is based on the idea that if we have enough data, the attacker would be a misfire to the attacker of the opposite engineer in a given transaction block.
However, this implementation was later modified and expanded by the Ethereum project, which used a different approach known as pruning. In fact, one of the clients of Bitcoin Satoshi Nakamoto, BCNF (Bitcoin neurone firmware) is based on this cutting mechanism.
Pruning includes the identification of the transaction history subset, which can be safely rejected without exposing security or revealing too much information. The idea is to create a “fingerprint” of transactions that are not necessary to understand the structure and dynamics of blockchain.
So does Ethereum implement this cutting mechanism? Unfortunately, the answer is “no”. Although it is likely that Satoshi Nakamoto has never intended to use his Bitcoin client in a public network, such as Ethereum, which uses a different consensus algorithm (Proof-of-Stake) and the transaction verification process.
The story of Blockchain Ethereum, known as “Blocklog”, contains all transactions that have ever been extracted in the Ethereum network. Although this block of flats can provide valuable information about the activity and evolution of the network over time, it does not contain any pruning the history of the transaction.
However, there are some indirect benefits of pruning. By analyzing a large number of blocks, you can identify patterns and correlations between various transactions that may indicate future events or security threats. In addition, pruning can help reduce blockchain storage requirements, because it only stores the necessary information for blockchain reconstruction.
To sum up, while the Ethereum trimming mechanism was inspired by the original Bitcoin Satoshi Nakamoto client, he was not implemented on the platform due to the differences in consensus algorithms and transaction verification processes. Nevertheless, this approach offers insight into the potential consequences of security in the history of pruning transaction.
