Miden node RPC
The RPC is an externally-facing component through which clients can interact with the node. It receives client requests (e.g., to synchronize with the latest state of the chain, or to submit transactions), performs basic validation, and forwards the requests to the appropriate components. RPC is one of components of the Miden node.
Architecture
TODO
Usage
Installing the RPC
The RPC can be installed and run as part of Miden node.
API
The RPC serves connections using the gRPC protocol on a port, set in the previously mentioned configuration file. Here is a brief description of supported methods.
CheckNullifiers
Gets a list of proofs for given nullifier hashes, each proof as a sparse Merkle Trees
Parameters:
nullifiers
:[Digest]
– array of nullifier hashes.
Returns:
proofs
:[NullifierProof]
– array of nullifier proofs, positions correspond to the ones in request.
GetBlockHeaderByNumber
Retrieves block header by given block number, optionally alongside a Merkle path and the current chain length to validate its inclusion.
Parameters
block_num
:uint32
(optional) – the block number of the target block. If not provided, the latest known block will be returned.
Returns:
block_header
:BlockHeader
– block header.
GetBlockByNumber
Retrieves block data by given block number.
Parameters
block_num
:uint32
– the block number of the target block.
Returns:
block
:Block
– block data encoded in Miden native format.
GetNotesById
Returns a list of notes matching the provided note IDs.
Parameters
note_ids
:[NoteId]
- list of IDs of the notes we want to query.
Returns
notes
:[Note]
- List of notes matching the list of requested NoteIds.
GetAccountDetails
Returns the latest state of an account with the specified ID.
Parameters
account_id
:AccountId
– account ID.
Returns
account
:AccountInfo
– latest state of the account. For public accounts, this will include full details describing the current account state. For private accounts, only the hash of the latest state and the time of the last update is returned.
SyncState
Returns info which can be used by the client to sync up to the latest state of the chain for the objects (accounts, notes, nullifiers) the client is interested in.
This request returns the next block containing requested data. It also returns chain_tip
which is the latest block number in the chain.
Client is expected to repeat these requests in a loop until response.block_header.block_num == response.chain_tip
, at which point the client is fully synchronized with the chain.
Each request also returns info about new notes, nullifiers etc. created. It also returns Chain MMR delta that can be used to update the state of Chain MMR. This includes both chain MMR peaks and chain MMR nodes.
For preserving some degree of privacy, note tags and nullifiers filters contain only high part of hashes. Thus, returned data contains excessive notes and nullifiers, client can make additional filtering of that data on its side.
Parameters
block_num
:uint32
– send updates to the client starting at this block.account_ids
:[AccountId]
– accounts filter.note_tags
:[uint32]
– note tags filter. Corresponds to the high 16 bits of the real values.nullifiers
:[uint32]
– nullifiers filter. Corresponds to the high 16 bits of the real values.
Returns
chain_tip
:uint32
– number of the latest block in the chain.block_header
:BlockHeader
– block header of the block with the first note matching the specified criteria.mmr_delta
:MmrDelta
– data needed to update the partial MMR fromrequest.block_num + 1
toresponse.block_header.block_num
.accounts
:[AccountSummary]
– account summaries for accounts updated afterrequest.block_num + 1
but not afterresponse.block_header.block_num
.transactions
:[TransactionSummary]
– transaction summaries for transactions included afterrequest.block_num + 1
but not afterresponse.block_header.block_num
.- Each
TransactionSummary
consists of thetransaction_id
the transaction identifier,account_id
of the account that executed that transaction,block_num
the block number in which the transaction was included.
- Each
notes
:[NoteSyncRecord]
– a list of all notes together with the Merkle paths fromresponse.block_header.note_root
.nullifiers
:[NullifierUpdate]
– a list of nullifiers created betweenrequest.block_num + 1
andresponse.block_header.block_num
.- Each
NullifierUpdate
consists of thenullifier
andblock_num
the block number in which the note corresponding to that nullifier was consumed.
- Each
SubmitProvenTransaction
Submits proven transaction to the Miden network.
Parameters
transaction
:bytes
- transaction encoded using Miden's native format.
Returns
This method doesn't return any data.
