The Most Important Project in Bitcoin (You probably haven't heard of)

— Hashers vs. miners: A critical distinction where hashers operate mining machines but don't decide block contents, while real miners run full nodes, verify transactions, and build block templates themselves.

— Mining pool centralization risk: Only a handful of major pools control block construction and transaction selection; five pools could theoretically censor the network if coordinated by government pressure.

— Datum and Stratum v2 protocols: These solutions restore individual miner control of block templates within pools, allowing hashers to become miners again without leaving pooled operations.

— Censorship resistance mechanism: When miners build their own blocks, pools cannot censor without removing miners from the network, which instantly eliminates the pool's hash rate and power.

— Slipstream and policy debates: Mining pool centralization is the real reason Slipstream (out-of-band payments to pools) works; solving miner decentralization naturally resolves this concern.

— Node operation requirement: To safely build block templates, participants must run full nodes to verify transactions and UTXOs; otherwise they cannot know what is valid to include.

— Run your own full node and consider participating in pools implementing Datum or Stratum v2 to restore individual block-building authority rather than delegating transaction selection to pool operators.

— Support or migrate hash rate toward mining implementations (Ocean, DMND) that prioritize individual miner control; this is the primary defense against protocol-level censorship over the long term.
