Bitcoin Layer 2 Stacks rolls out SIP-034 upgrade, improving throughput by resetting only exhausted limits and unlocking higher efficiency for DeFi workloads

Stacks has rolled out SIP-034 on mainnet, a protocol upgrade aimed at improving how the Bitcoin-linked network allocates block capacity for decentralized finance activity. The core change is that Stacks now resets only the specific resource limit that is exhausted, rather than resetting all limits together, which makes block usage more efficient and allows some DeFi applications to process substantially more activity—reported as up to 30x in certain cases. The upgrade matters because Stacks is one of the main efforts to add smart-contract functionality and DeFi to Bitcoin without changing Bitcoin’s base layer. According to Stacks’ roadmap, SIP-034 is paired with other builder-focused improvements such as new contract and signature verification functions, and it is designed to expand effective capacity for more complex, read-heavy DeFi workloads like concentrated liquidity and advanced AMM designs. While the upgrade does not directly change STX token economics, higher network throughput could still translate into more transactions and fee activity if usage grows.
