BlockMetadata

sf.firehose.v2.BlockMetadata

uint64num = 1

Num is the block number of this response's block.

stringid = 2

ID is the block ID of this response's block. The ID actual representation is chain specific.

Antelope & Ethereum uses hex.
NEAR & Solana uses base58.

Refer to the chain documentation for more details.

uint64parent_num = 3

ParentNum is the block number of the parent of this response's block

stringparent_id = 4

ParentID is the block ID of the parent of this response's block. If this response is the genesis block, this field is empty.

The ID actual representation is chain specific.

Antelope & Ethereum uses hex.
NEAR & Solana uses base58.

Refer to the chain documentation for more details.

uint64lib_num = 5

LibNum is the block number of the last irreversible block (a.k.a last finalized block) at the time of this response' block. It determines the finality of the block.

Timestamptime = 6

Time is the time at which the block was produced.

InfoRequest

sf.firehose.v2.InfoRequest

No fields.

InfoResponse

sf.firehose.v2.InfoResponse

string[]chain_name_aliases = 2

stringfirst_streamable_block_id = 4

InfoResponse.BlockIdEncodingblock_id_encoding = 5

This informs the client on how to decode the block_id field inside the "Clock" message as well as the first_streamable_block_id above.

string[]block_features = 10

features describes the blocks. Popular values for EVM chains include base, extended or hybrid.

Request

sf.firehose.v2.Request

int64start_block_num = 1

Controls where the stream of blocks will start.

The stream will start inclusively at the requested block num.

When not provided, starts at first streamable block of the chain. Not all chain starts at the same block number, so you might get an higher block than requested when using default value of 0.

Can be negative, will be resolved relative to the chain head block, assuming a chain at head block #100, then using -50 as the value will start at block #50. If it resolves before first streamable block of chain, we assume start of chain.

If start_cursor is given, this value is ignored and the stream instead starts immediately after the Block pointed by the opaque start_cursor value.

stringcursor = 2

Controls where the stream of blocks will start which will be immediately after the Block pointed by this opaque cursor.

Obtain this value from a previously received Response.cursor.

This value takes precedence over start_block_num.

uint64stop_block_num = 3

When non-zero, controls where the stream of blocks will stop.

The stream will close after that block has passed so the boundary is inclusive.
