We need to correct the file type issue and re-run the script to search for the
verifyMultifunction usage in Solidity files.
The search results show multiple instances of the
verifyMultifunction being used. We need to ensure that these usages are consistent with the new function signature.Instances to check:

verifyMulti.

- The instances in

- The function
BinaryMerkleTree.verifyMultiinsrc/lib/tree/binary/test/BinaryMerkleTree.t.solmatches the new signature.- The other instances refer to different functions with similar names but different signatures.
Action:
- Verify that the function
BinaryMerkleTree.verifyMultiinsrc/lib/tree/binary/test/BinaryMerkleTree.t.solis correctly implemented according to the new signature.Final Response:
LGTM! Verify the function usage in the codebase.
The function
verifyMulticorrectly converts data into leaf nodes and callsverifyMultiHashesfor verification. The functionBinaryMerkleTree.verifyMultiinsrc/lib/tree/binary/test/BinaryMerkleTree.t.solmatches the new signature.

We need to correct the syntax error in the script and ensure that we provide actual values for the placeholders. Here's the updated script:
This script should now run without syntax errors, assuming valid API key and contract address are provided.
We will now search the codebase for the definitions and usages of the new functions and events (
initialize,submitDataRootTupleRoot,updateValidatorSet,verifyAttestation,DataRootTupleRootEvent,ValidatorSetUpdatedEvent) to ensure they are correctly integrated.
The new functions and events are correctly defined and integrated into the
Wrappersstruct.The new functions (
initialize,submitDataRootTupleRoot,updateValidatorSet,verifyAttestation) and events (DataRootTupleRootEvent,ValidatorSetUpdatedEvent) are present and correctly defined in the smart contract and the Go wrapper.
- The functions and events are found in
src/Blobstream.sol,wrappers/Blobstream.sol/wrapper.go, and related test files.- The Go wrapper file
wrappers/Blobstream.sol/wrapper.goincludes methods for these functions and events, confirming their integration.Scripts executed

Overview
As part of a Blobstream integration for a zkEVM rollup, we're validating merkle proofs of full blobs into data roots in the EVM. While it is possible to use a series of binary tree inclusion proofs, this amounts to a lot of unnecessary sha256 hashing, which imposes a high proving cost on the zkEVM.
This pull request will add mulitproofs to the binary tree library.
