A workshare is a complete merge-mining proof carried by a Kronex block: the
parent-chain header, the coinbase transaction that commits to Kronex, and the
Merkle path binding one to the other.
Because the proof is self-contained, anyone can verify it from the data it
carries, and it cannot be forged more cheaply than the hashrate it claims.
Identity and difficulty
Every workshare has a canonical identity, its workshareId, and an achieved
difficulty derived from its hash.
shareDifficulty is the achieved proof-of-work difficulty of that share,
rendered as a fixed-12 decimal string. It is not the threshold the network was
asking for, and it is not a hex quantity.
Durable history
The workshare history an explorer indexes is served from immutable snapshots
with reorg-checked cursors, and it is bound to canonical blocks only. Its result
and error shapes are frozen by contract, so an indexer built against it does not
break under a version bump.
Start from krnx_getWorkshareCapabilities,
which reports whether the API is enabled, the canonical history anchors, the
frozen limits and the parent-chain mappings. Then page through
krnx_getWorkshares. See
Explorer integration for the paging rules.
Getting paid
Workshares in a block share the reward pool with the sealer and any uncles. To
confirm that a specific share was credited, call
krnx_getWorkshareReward with the workshareId
recorded at submit time, or with the pair powId and powHash.
The reward itself is computed from a curve that is configured per parent chain —
see Rewards.
