Deep Dive
1. v0.14.3 Mainnet Launch (22 June 2026)
Overview: This minor upgrade went live on schedule, focusing on core protocol efficiency. It introduces dynamic adjustments to the Layer 2 gas base fee, which is now priced in STRK and responds to network demand.
The update aims to increase block production speed while reducing the target L2 gas consumption per block. It also deprecates the older JSON-RPC v0.8, requiring developers and infrastructure providers to update their tooling for compatibility.
What this means: This is bullish for STRK because it deepens the token's utility by directly linking gas fees to network activity, potentially creating more consistent demand. Users benefit from more predictable fee mechanics, especially during periods of low congestion.

2. v0.14.2 Shinobi Upgrade (21 April 2026)
Overview: This major upgrade, known as Shinobi, brought native privacy infrastructure to the mainnet. It introduced SNIP-36, which allows the network's consensus layer to natively verify STARK proofs referenced in transactions.
This technical foundation enables the STRK20 token standard for private balances and the strkBTC wrapper for private Bitcoin DeFi. The upgrade also rebalanced storage costs versus base transaction fees via SNIP-37.
What this means: This is bullish for STRK because it establishes Starknet as a unique privacy-preserving rollup, opening new use cases in private finance and Bitcoin integration. For users, it means the ability to conduct shielded transactions seamlessly without relying on third-party applications.

3. v0.14.1 Prover Optimization (10 December 2025)
Overview: This upgrade optimized the prover by changing the hash function used for compiled class hashes from Poseidon to BLAKE. This change is the first step in migrating to the more efficient Stwo prover system.
It also implemented a working EIP-1559-style fee market for L2 gas, making fees more predictable and tied to congestion. During low activity, blocks can finalize in as little as two seconds.
What this means: This is bullish for STRK because it directly reduces the cost and time for developers to generate proofs, improving network scalability. End-users experience faster confirmations during quiet periods and a more stable fee structure.
