# Workshares

> Self-verifying proofs of parent-chain work, indexed against canonical blocks and paid.

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.

<Warning>
  `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.
</Warning>

## 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`](/rpc/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`](/rpc/krnx/getWorkshares). See
[Explorer integration](/guides/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`](/rpc/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](/learn/rewards).
