eth-components

Implementing the basic parts of a blockchain (Ethereum/Blockchain-based)

Usage

For each component, there is a respective branch to learn more about it

Inside each branch, there will be a Makefile

• make or make all is used to setup everything and run the program
• make clean is used to remove everything created for make and reset to just the code

Components

merkle_root

One of the core items in maintaining the verification property in the blockchain. Merkle-root implementation is implemented such that a Merkle root can be extracted from an array of data (populated by sample files). This is not how a typical Merkle tree or a Merkle-Patricia tree (MPT) would be implemented, as a MPT should allow for sibling verification and proofs of membership/non-membership

block

More similar to a Bitcoin block, where it is based on proof of work (Solving for a nonce). This holds a collection of data, which hashes to a merkle_root, and are the singular elements of a blockchain

validation

A core process in preserving the immutable nature of previous blocks is to only add blocks to valid blockchains. This function essentially "checks" the "chain links" between blocks and ensure that they are valid (merkle root of one correctly corresponds with the hash of the one that precedes it)
