During this reporting period, I focused on making the statement-store production-ready, supporting the Ethereum-compatible smart contract launch, and improving parachains block confidence.
The statement-store is a substrate component that can be used by web3 applications to exchange signed statements across the network. Although it's been around for a while, it hasn't been used in production yet.
To evaluate the performance of statement-store, I implemented the full scenario benchmarks and isolated tests. Initial results showed that nodes could not handle more than 300 clients before hitting bottlenecks.
I found and fixed a deadlock in statement gossiping, and optimized the propagation protocol to reduce network overhead. After these changes, nodes can now handle statement exchange among 50K clients within one minute.
The work is ongoing. We're making the statement-store a convenient tool for web3 developers by updating the RPC interface and improving scalability.
As part of launching Solidity smart contracts on AssetHub, I worked on embedding EVM in foundry-polkadot and optimizing the Trie database.
In pallet-revive, I added testing helpers that let developers set up specific scenarios like pre-funding accounts or modifying contract storage. For foundry-polkadot, I worked on translating state changes between REVM and PVM to keep execution consistent, and implemented the CREATE opcode.
I also finished the Trie Cache benchmarks that measure smart contract throughput on Asset Hub.
To improve Polkadot chains reliability, we started a block confidence initiative. During the reporting period, I improved the collation metrics to separate expected fork-based drops from actual problems.
I kept maintaining polkadot-introspector, our monitoring tool that tracks on-chain data about parachain performance and network health.
In the next period, I'll keep working on network scalability and performance, focusing on statement-store production readiness and parachain throughput.
