Evidence

In the current reporting period, my main contributions have been related to Omni-Node and parity-scale-codec.

Omni-Node

I worked on separating the generic logic from polkadot-parachain-bin in a library (polkadot-parachain-lib): https://github.com/paritytech/polkadot-sdk/pull/5288 . This enables the parachain teams to build their own slightly customized node, without duplicating the code in polkadot-parachain-bin.

I have added support for starting nodes with u64 block number in polkadot-parachain-lib: https://github.com/paritytech/polkadot-sdk/pull/5269 . This was needed in order to support a parachain use case: https://github.com/paritytech/polkadot-sdk/issues/4787 .

I have added support for starting a node with manual seal to polkadot-parachain-lib: https://github.com/paritytech/polkadot-sdk/pull/5586 . This is aimed at improving parachain development/debugging speed.

parity-scale-codec

I worked on adding support for tracking and limiting the heap memory usage while decoding: https://github.com/paritytech/parity-scale-codec/pull/616 .

Other

I added benchmarks for the BEEFY forking equivocation logic: https://github.com/paritytech/polkadot-sdk/pull/5188 .
