Deep Dive
1. Prover Optimization & Blake Hash (10 December 2025)
Overview: This update changes how the network computes cryptographic hashes, making the process of generating proofs about 8x more efficient. For users, this means developers face lower costs for deploying and interacting with contracts over time.
The core technical change replaces the Poseidon hash function with Blake2s for computing compiled class hashes. This is a strategic step toward adopting the next-generation Stwo prover. Existing contract classes will gradually migrate to the new system as they are used in transactions.
What this means: This is bullish for STRK because it directly lowers the operational cost for developers building on Starknet, making the network more attractive for new projects. It also lays the groundwork for significantly faster and cheaper proofs in the future.

2. Faster Block Closure & Fee Predictability (10 December 2025)
Overview: The upgrade introduces a fully functional fee market similar to Ethereum's EIP-1559. During periods of low activity, blocks can finalize in as little as 2 seconds, speeding up user experience when the network isn't busy.
This change decouples Starknet's fee mechanics from Ethereum's gas prices, creating a more predictable and independent pricing model for L2 resources (l2_gas). The network now targets a specific gas price, with fees adjusting based on demand.
What this means: This is bullish for STRK because it leads to a smoother and faster experience for everyday users and more stable, predictable transaction costs, which is crucial for reliable DeFi and app usage.

3. Real-Time Cost Alignment Model (10 December 2025)
Overview: This adjustment ensures gas fees more accurately cover the real cost of transactions, creating a healthier economic foundation for the network's validators and infrastructure.
While base fees may see a slight increase to achieve this alignment, the team notes that simple transfers will remain under one cent. The change is designed to support long-term decentralization by ensuring network security is properly incentivized.
What this means: This is neutral to bullish for STRK. While it aims for sustainable network economics (a long-term positive), users might see marginally higher fees during congested periods. The overall goal is a more robust and decentralized network.

Conclusion
The latest codebase updates solidify Starknet's path toward a more efficient, user-friendly, and economically sustainable Layer 2, with a clear focus on proving efficiency and fee market maturity. How will these foundational improvements accelerate the adoption of Starknet's expanding BTCFi ecosystem?
