Definition ∞ Sequential proof-of-work is a variant of proof-of-work where the computational tasks required for mining blocks must be performed in a specific, ordered sequence. This design makes it difficult to parallelize the mining process, thereby reducing the advantage of specialized hardware like ASICs. It aims to promote decentralization by favoring general-purpose computing. This approach enhances equitable participation.
Context ∞ News discussing ASIC resistance and the decentralization of mining often features sequential proof-of-work algorithms. Reports on new cryptocurrency protocols or protocol upgrades highlight how this approach can help prevent the concentration of mining power. This method seeks to maintain a more equitable distribution of mining opportunities across the network, supporting long-term network health.
