Introduction This proposal outlines the planned upgrade to Starknet v0.14.0, as detailed in SNIP 30. The upgrade marks a foundational milestone in the Starknet decentralization roadmap by introducing decentralized sequencing through a multi-sequencer architecture, Tendermint-based consensus. v0.14.0 also brings pre-confirmations, a significant UX improvement offering subsecond feedback on transaction status. Together with Staking v2, this version lays down key technical infrastructure needed for trust-minimized, censorship-resistant block production.

Starknet v0.14.0 addresses three primary goals:

  • Decentralizing Sequencing Infra: Shift from a single centralized sequencer to multiple sequencers taking turns to propose blocks and reach consensus.
  • Improving Transaction Finality UX: Introduce pre-confirmations and candidate statuses to improve feedback latency and transparency.
  • Establishing an EIP-1559 Fee Market: Introduce a fair and adaptive gas fee mechanism with a minimum base fee, independent of Ethereum L1 gas volatility.

Vote Details A vote will be conducted to determine the approval or rejection of the following features proposed in Starknet v0.14.0:

  • Multi-Sequencer Architecture with Tendermint Consensus
  • Pre-Confirmations for Faster UX
  • Fee Market Introduction with Minimum Base Price Key Features
  1. Multi-Sequencer Architecture
  • Sequencer Rotation: Three sequencers will take turns proposing blocks.
  • Consensus Protocol: Tendermint-style consensus will finalize each block with a threshold of 2-of-3 agreement (sufficient given all sequencers are trusted and operated by StarkWare).
  • One-Block Finality: Blocks are finalized immediately, improving predictability and reducing reorg risks.
  1. Pre-Confirmations
  • New Transaction Statuses: Introduces CANDIDATE and PRE_CONFIRMED transaction states.
  • Latency Improvements: PRE_CONFIRMED status is expected in ~0.5 seconds under normal conditions.
  • User Experience: Drastically improved feedback loop for users submitting transactions, with high finality guarantees.
  1. Fee Market with Minimum Base Price
  • EIP-1559 Model: Each transaction must bid on L1 gas, L2 gas, and L1 data gas. Only bids above the current base fee will be accepted.
  • Tip Mechanism: Sequencers receive tips in addition to base fees for L2 gas.
  • Minimum L2 Gas Price: Set to 3 gFRI, approximately double the 7-day average at time of writing, ensuring sustainability while maintaining low costs.

Benefits Improved UX: Faster feedback on transaction status via pre-confirmations. Robust Economics: Adaptive and predictable fee market aligned with offchain infrastructure costs. Foundational Decentralization: Prepares infrastructure for future phases of validator-operated sequencing and proving. Timeline

  • Q3 2025: Testnet deployment and ecosystem testing
  • Q3 2025: Mainnet deployment (with ~15 min expected downtime during upgrade) Conclusion

Starknet v0.14.0 represents a major step toward achieving full decentralization by introducing decentralized block production and improving user experience through faster transaction feedback. This upgrade also introduces a sustainable fee model for future network scalability. We encourage all community members to participate in this vote. Please vote For, Against, or Abstain.
