• Node: v0.2.4

Changelog

This is an important version as it supports the next coming version Upgrade ForkID5 and also known as Dragon_Fruit. This version offers

• Protect grpc input from invalid values
• Added several generalizations to the prover code:
  -- When calling getCommittedPols, the number of committed pols is sent by getting that info from starkInfo.
  -- CompressorCommitPolsStarks is now agnostic to the number of committed polynomials, which is specified by parameter.
  -- ConstantPolsStarks is now agnostic to the number of constant polynomials.
  -- ExecFile is now agnostic to the number of committed polynomials.
  -- Proof2zkinStark, which is used to generate the zkin of the recursive2, is now generalized so the number of steps isn't fixed but sent by parameter
• Supporting Goldilocks avx512
• Created LICENSE file
• Fixed README file
• Added new rapidSnark and ffiasm files for FFlonk optimizations
• Renamed StateDB to HashDB
• Only last state is now written to Database, deleting unrequired hashes/nodes before inserting them to Database.
• Created SMT::hashSaveZero() and SMT::hashSaveOne()
• Created Database::saveStateRoot() and call it from SMT
• Removed update from Database and HashDB
• Fixed: add multiWrite.Lock() to Database:dbSenderThread()
• Fixed program insertion in Database::sendData() query
• Call ctx.pHashDB->semiFlush() from FullTracer::onFinishTx(), in all forks
• Cache last EC points addition result
• New executor.proto: external request ID, effective gas price
• Fixed STOP missing opcode
• When exitProces() notify the rest of threads, not to start new activities
• Report evaluation counter in main SM executor logError method
• Upgrading number of threads for calcwitness
• Removed batches when calculating linear hashes since there is no intention of moving to GPU in a short period of time.
• Integrate E2E test into Github Actions (GHA) for continuous integration
• Created ForkID5 with new ROM
• Fixed Aggregator service test code to get final proof
• Read all rom.json constants
• Encoded FullTracer trace to save space (from release)
• Fixed OOC errors when no_counters=1 has been requested (from release)
• Deleted ctx.outLogs, which were unused
• Fixed DatabaseCache memory leak
• Implemented Unit Testing (UT)
• Replaced Tonelli-Shanks square root implementation by a power, given the prime mod 4 characteristics.
• Fixed depth in FullTracer ForkID5 (from release)
• Fixed FullTracer DELEGATECALL format not to include leading zeros
• Completed Optimizations on ECRecover: New implementation using Jacobian coordinates has been integrated in the different versions of Executors available. For the ROM-based executor, as intermediate results are needed, those are stored into an intermediate buffer and once the calculation is finished are converted from projective to affine coordinates in parallel.
• Added LOG_SMT_KEY_DETAILS to Main Executor
• Fixed FullTracer logs index to be sequential
• Updated testvectors/performance with new files including effective gas price byte
• Checked that pEntry→ifa_addr is not null in getIPAddress()
• Changed default value of config.dbReadRetryCounter to 10
• Logging executor input in a trace
• Fixed database connection management in exception catch
• Call multiWrite.acceptIntray() from Database::senderThread() to rescue the hashes from nodesIntray/programIntray
• Disabled Input.bUpdateMerkleTree by default, so that Prover.genBatchProof() does not write data in Database
• Integrated HashDBTest into UnitTest
• Fixed Database to search not only in cache, but also in multiWrite data
• Fixed DatabaseCache to clear dataSize when reset
• Updated state root instead of inserting; create it during initialization if database is empty
• New invalid RLP ROM error support
• Fixed ECRecover for case posUsed=-1 in native main executor code

Prover v2.0.1-hotfix.1 config changes
