Starknet

• API changes:
  • Block hash calculation has changed and is now implemented in Rust
  • Starknet block:
    • receipt_commitment, state_diff_commitment, and state_diff_length are added to the block (only for new blocks)
    • execution_resources in transaction receipt now contains the total gas consumed
  • Block signature: sign the block hash instead of the block hash and the state diff commitment
  • get_block_traces and get_transaction_trace are deprecated from version 0.13.2
• New syscall: sha256
• New builtins: add_mod, mul_mod, range_check96
• Applicative-recursion: Until now, we have had a state update on L1 for every L2 block. Applicative recursion enables breaking this coupling by aggregating block proofs offchain and sending onchain a single state update proof per many blocks
• Performance:
  • Compute block commitment in Rust
  • Execute transactions concurrently (implement a variant of block-STM)
• Bug fixes:
  • StateUpdate: exclude empty storage diff lists

Starknet

• Use EIP 4844 for cheaper data availability

• Time-related syscalls when called from account contract's __validate__:

  • timestamp will return the hour, rounded down
  • block_number will return the block number rounded down to the nearest multiple of 100

• Optimization: Load only the used functions in a contract into memory when generating the proof

• Add starknet-compiled-class-hash command

• API changes:

  • Starknet block:
    • New field l1_da_mode, which indicates whether EIP 4844 was used in the block
    • eth_l1_gas_price and strk_l1_gas_price were replaced, and the information now contains the data gas price (EIP 4844) in addition to the regular gas price
    • execution_resources in transaction receipt now contains:
      • data availability resources
      • syscall resources (which contribute to the transaction fee but were not included in the receipt until this version)
    • transaction_commitment and event_commitment are added to the block (zero is returned for old blocks)

• Infrastructure updates:

  • Support multiple L1 providers

• CairoZero:

  • Remove 128-bit limitation from search_sorted_lower

Starknet

• Add transaction v3:
  • Fee payment in STRK
  • Reserved fields for future features, such as volition and payment master
• get_block API: Rename the gas_price field to eth_l1_gas_price and add a new field strk_l1_gas_price (this applies to old blocks as well)
• Update Sierra version used in Starknet to 1.4.0 (introduced in crate version v2.4.0 of the cairo package)
• Improved performance of secp256k1_mul and secp256r1_mul syscalls

Starknet

• Performance optimizations in the gateway, the computation of the Patricia storage root and block hash
• Support secp256r1 syscalls in the Starknet OS. Thanks to Braavos for adapting the secp256k1 code to secp256r1!
• Restriction for __validate__ and the constructor of DeployAccount transactions:
  • Restrict access to sequencer_address in the get_execution_info syscall - return zero values
  • Restrict access to some syscalls:
    • Cairo contracts: get_block_hash
    • CairoZero contracts: get_sequencer_address

CairoZero

• Move structs that are common to secp256k1 and secp256r1 to a separate file
