Ethereum Classic (ETC) stands out for its commitment to immutability and preserving the original principles of blockchain technology. Its uniqueness lies in maintaining the unaltered history of transactions, adhering to the concept of "code is law." Unlike Ethereum (ETH), which underwent a hard fork to rectify the consequences of a hack, ETC remained true to the immutability principle, refusing to make changes to the blockchain, even in the face of security incidents.
