Schemas

StreamingFast Firehose schemas

Chain-specific schemas
Firehose currently has Layer 1 Protocol Buffer schemas for several different blockchains. Follow the links below to find the schemas relevant to the blockchain being targeted.
​Ethereum Protobuf Definitions​
​NEAR Protobuf Definitions​
Solana Protobuf Definitions:
​Version 1, original Solana data model
​Version 2, StreamingFast enriched data model
​Cosmos Protobuf Definitions​
​Arweave Protobuf Definitions​
​Aptos Protobuf Definitions​
The bstream Block
The bstream Block is the main blockchain-agnostic object flowing throughout Firehose.
Note: The stream Block is the envelope used to pass blockchain-specific Block objects, for Ethereum, as an example.
Versioning
Coming Soon
Discussion on general multi-chain considerations of versioning in the Firehose suite to answer questions such as:
when do we change the namespace,
when do we bump the version field in the block.
