Pool [20].The miners use a newly implemented software that performs needed calculations for the proposed consensus protocol. 5.1.1. Modified Ethereum PlatformGeth is the current up-to-date implementation of the Ethereum protocol written in the Go programming language. One of the principles of Ethereum is modularity, so Geth already has a certain predefined interface that consists of the following modules:The Author module returns the Ethereum address of the account that has mined the block with the given header. If the implemented consensus protocol is based on signatures (such as Etherium’s Clique protocol), this address can be differently compared to the address of the coinbase account, which represents the base account of every Ethereum node.The VerifyHeader module checks whether the header of the new mined block follows the rules of the consensus algorithm that is implemented. This module may check the validity of the crypto seal if the value of its parameter, seal, is set to true, which can also be done explicitly using the VerifySeal module. The module uses argument chain to read the content of the blockchain.The VerifyHeaders module is similar to that of VerifyHeader. The difference is that this module verifies a series of block headers using the chain reader as the VerifyHeader module does. The module returns two go channels as return values: the quit channel that serves to abort the operations of the module and the result channel that is used to asynchronously transfer the results of the verification, following the order of the blocks in the module’s argument list.The VerifyUncles module checks the validity of the uncles of the given block. Uncle blocks are blocks that were mined at the same time when the parent of the given block was mined, but have not made it into the blockchain. Those blocks must be valid, as Ethereum protocol stores them and gives some reward to the nodes that mined them. Uncle verification is done in the same way as the verification of other blocks that are part of the blockchain.The VerifySeal module verifies that the crypto seal of the given block is valid according to the rules of the implemented consensus protocol.The Prepare module is used to initialize the consensus fields of the block header according to the rules of the implemented consensus protocol.The Finalize module adds the final values to the block, for example, a reward for finding the block, after the crypto seal value has been added to the block. The result of this module is the block that will be added to the blockchain if the majority of nodes accept it.The Seal module generates a new block for a given input block with the local miner’s crypto seal, which depends on the block itself, placed on top of it. This is the main module of the consensus algorithm, as its core is the process of mining.The CalcDifficulty module returns the difficulty of the next block. This adjustment ensures that the time that passes until the new block is added to the blockchain stays always the
