01 / PURPOSE
An independent ledger for RUB.
Ruble Core is an independent public blockchain with RUB as its native asset. It uses SHA-256d proof of work and supports both native mining and Bitcoin merged mining.
RUB transactions form their own ledger. Full nodes validate that ledger under Ruble’s consensus rules. RUB is an independent digital asset with no peg to a national currency.
02 / PROOF OF WORK
Shared mining work. Separate block results.
Native miners search directly for work that meets Ruble’s target. With AuxPoW, parent-chain work and its proof can be submitted for Ruble validation as well.
The key distinction is the target each network applies. RUB can accept a valid AuxPoW result even when that work does not find a Bitcoin block. If a Bitcoin block is also found and accepted, its reward is an additional result on the Bitcoin chain.
Ruble continues to validate its own blocks and transactions. Bitcoin merged mining provides another source of work for the RUB chain.
03 / TRANSACTIONS & VALIDATION
Rules are checked by full nodes.
Transactions spend existing outputs and create new outputs. Nodes check the inputs, signatures and applicable consensus conditions. A receiving address identifies where an output can be sent; it is not a private key.
RUB uses eight decimal places. The network’s target interval is three minutes, with per-block ASERT adjustment and a two-hour half-life. Newly mined RUB outputs have a 100-block maturity requirement.
Network parameters and address formats →04 / POOLS & VERIFICATION
From work records to on-chain evidence.
A pool accepts shares, records work and allocates earned rewards according to its mining profile. Those account records describe the pool’s operations. A payout transaction can be verified on the relevant blockchain.
Explorer data makes chain activity easier to inspect. Bitcoin block claims require separate Bitcoin-chain evidence; a Ruble AuxPoW block alone does not prove that a Bitcoin block was found.
