Represents a block body.

Used in: SignedBlock

• bytes block_body = 1

  Block body data encoded using [miden_serde_utils::Serializable] implementation for [miden_protocol::block::BlockBody].

Represents a block header.

Used in: SignedBlock, rpc.BlockHeaderByNumberResponse, rpc.SyncChainMmrResponse, rpc.SyncNotesResponse.NoteSyncBlock

• uint32 version = 1

  Specifies the version of the protocol.

• optional primitives.Digest prev_block_commitment = 2

  The commitment of the previous blocks header.

• fixed32 block_num = 3

  A unique sequential number of the current block.

• optional primitives.Digest chain_commitment = 4

  A commitment to an MMR of the entire chain where each block is a leaf.

• optional primitives.Digest account_root = 5

  A commitment to account database.

• optional primitives.Digest nullifier_root = 6

  A commitment to the nullifier database.

• optional primitives.Digest note_root = 7

  A commitment to all notes created in the current block.

• optional primitives.Digest tx_commitment = 8

  A commitment to a set of IDs of transactions which affected accounts in this block.

• optional ValidatorPublicKey validator_key = 9

  The validator's ECDSA public key.

• optional primitives.Digest tx_kernel_commitment = 10

  A commitment to all transaction kernels supported by this block.

• optional FeeParameters fee_parameters = 11

  Fee parameters for block processing.

• fixed32 timestamp = 12

  The time when the block was created.

Represents a block number.

Used as response type in: rpc.Api.SubmitProvenTx, rpc.Api.SubmitProvenTxBatch

Used as field type in: rpc.AccountRequest, rpc.AccountResponse

• fixed32 block_num = 1

  The block number of the target block.

Request for retrieving a block by its number, optionally including the block proof.

Used as request type in: rpc.Api.GetBlockByNumber

• fixed32 block_num = 1

  The block number of the target block.

• optional bool include_proof = 2

  Whether to include the block proof in the response.

Block ECDSA Signature.

Used in: SignBlockResponse, SignedBlock, rpc.SyncChainMmrResponse

• bytes signature = 1

  Signature encoded using [miden_serde_utils::Serializable] implementation for [crypto::dsa::ecdsa_k256_keccak::Signature].

Definition of the fee parameters.

Used in: BlockHeader

• optional account.AccountId native_asset_id = 1

  The faucet account ID which is used for native fee assets.

• fixed32 verification_base_fee = 2

  The base fee (in base units) capturing the cost for the verification of a transaction.

Response containing the block data and optionally its proof. Contains empty values for both blocks and proofs that are not found. Some blocks may not yet be proven so it is possible to retrieve a block without a proof even if the proof has been requested.

Used as response type in: rpc.Api.GetBlockByNumber

• optional bytes block = 1

  The requested block data encoded using [miden_serde_utils::Serializable] implementation for [miden_protocol::block::SignedBlock].

• optional bytes proof = 2

  The block proof encoded using [miden_serde_utils::Serializable] implementation for [miden_protocol::block::BlockProof], if requested and available.

Represents a block number or nothing.

• optional fixed32 block_num = 1

  The block number of the target block.

Represents a proposed block.

Used as request type in: validator.Api.SignBlock

• bytes proposed_block = 1

  Block data encoded using [miden_serde_utils::Serializable] implementation for [miden_protocol::block::ProposedBlock].

Response to a `SignBlock` request: the block signature together with the commitment of the block header that the validator actually signed, so the block producer can detect a block-hash mismatch.

Used as response type in: validator.Api.SignBlock

• optional BlockSignature signature = 1

  The validator's signature over the block.

• optional primitives.Digest block_commitment = 2

  Commitment of the block header that the validator signed.

Represents a signed block.

• optional BlockHeader header = 1

• optional BlockBody body = 2

• optional BlockSignature signature = 3

Validator ECDSA public key.

Used in: BlockHeader

• bytes validator_key = 1

  Signature encoded using [miden_serde_utils::Serializable] implementation for [crypto::dsa::ecdsa_k256_keccak::PublicKey].
