Datum Protocol
Datum Protocol lets Bitcoin miners build their own block templates while mining through a pool.
Definition
Datum Protocol is a Bitcoin mining protocol that lets miners create their own block templates instead of accepting every block layout from a pool. DATUM stands for Decentralized Alternative Templates for Universal Mining. Its goal is to give miners more control while keeping the lower payout variance of pool mining.
How It Works
In a typical pool setup, a miner connects through a protocol such as Stratum Protocol. The pool builds the candidate block, chooses the transactions, sends work to the miner, and submits any valid block.
Datum changes that split. A miner runs a DATUM gateway alongside a Bitcoin full node. The node watches the network, validates transactions, and helps assemble a local block template. A block template is the draft version of a block: it includes the previous block reference, selected transactions, the reward transaction, and data needed for proof of work.
The mining hardware still does the same job. It repeatedly hashes candidate block headers, changes nonce values, and submits shares that prove contributed hash rate. If the miner finds a hash that meets the network target, the block can be broadcast from the miner’s node.
The pool still tracks valid shares, coordinates payouts, and reduces the income swings that make pure solo mining impractical. The difference is that the miner is no longer only renting hash power to a pool-controlled template.
Why It Matters
Datum matters because block construction is a source of power. Whoever builds the template can influence which transactions are included and how blocks are relayed.
For miners, DATUM can mean more sovereignty without giving up pooled payouts. A miner can use their own node, verify their view of Bitcoin, and participate more directly in block creation. That reduces reliance on centralized pool infrastructure and can make mining more resistant to censorship or outages.
It also raises the technical bar. Running DATUM is more involved than entering a pool URL into an ASIC dashboard. Miners need reliable node infrastructure, correct gateway configuration, and enough discipline to keep stale work and downtime low.
