Péter Szilágyi 9326a118c7 beacon, core, eth, miner: integrate witnesses into production Geth (#30069) ... This PR integrates witness-enabled block production, witness-creating payload execution and stateless cross-validation into the `engine` API. The purpose of the PR is to enable the following use-cases (for API details, please see next section): - Cross validating locally created blocks: - Call `forkchoiceUpdatedWithWitness` instead of `forkchoiceUpdated` to trigger witness creation too. - Call `getPayload` as before to retrieve the new block and also the above created witness. - Call `executeStatelessPayload` against another client to cross-validate the block. - Cross validating locally processed blocks: - Call `newPayloadWithWitness` instead of `newPayload` to trigger witness creation too. - Call `executeStatelessPayload` against another client to cross-validate the block. - Block production for stateless clients (local or MEV builders): - Call `forkchoiceUpdatedWithWitness` instead of `forkchoiceUpdated` to trigger witness creation too. - Call `getPayload` as before to retrieve the new block and also the above created witness. - Propagate witnesses across the consensus libp2p network for stateless Ethereum. - Stateless validator validation: - Call `executeStatelessPayload` with the propagated witness to statelessly validate the block. *Note, the various `WithWitness` methods could also *just be* an additional boolean flag on the base methods, but this PR wanted to keep the methods separate until a final consensus is reached on how to integrate in production.* --- The following `engine` API types are introduced: ```go // StatelessPayloadStatusV1 is the result of a stateless payload execution. type StatelessPayloadStatusV1 struct { Status string `json:"status"` StateRoot common.Hash `json:"stateRoot"` ReceiptsRoot common.Hash `json:"receiptsRoot"` ValidationError *string `json:"validationError"` } ``` - Add `forkchoiceUpdatedWithWitnessV1,2,3` with same params and returns as `forkchoiceUpdatedV1,2,3`, but triggering a stateless witness building if block production is requested. - Extend `getPayloadV2,3` to return `executionPayloadEnvelope` with an additional `witness` field of type `bytes` iff created via `forkchoiceUpdatedWithWitnessV2,3`. - Add `newPayloadWithWitnessV1,2,3,4` with same params and returns as `newPayloadV1,2,3,4`, but triggering a stateless witness creation during payload execution to allow cross validating it. - Extend `payloadStatusV1` with a `witness` field of type `bytes` if returned by `newPayloadWithWitnessV1,2,3,4`. - Add `executeStatelessPayloadV1,2,3,4` with same base params as `newPayloadV1,2,3,4` and one more additional param (`witness`) of type `bytes`. The method returns `statelessPayloadStatusV1`, which mirrors `payloadStatusV1` but replaces `latestValidHash` with `stateRoot` and `receiptRoot`.		2 months ago
