May 2026 highlights Nethermind delivery focused on robust receipt handling, improved peer-to-peer sync stability, and CI reliability. The work tightened Ethereum receipt logic to only respond when a block has zero transactions, clearly differentiate blocks with unknown receipts from legitimately empty receipts, and aligned tests and mocks with the Eth69/Eth70 protocol expectations. This reduces misbehavior, disconnect storms, and bootstrapping fragility in small networks, while increasing test coverage and regression safety. In addition, CI/test stability improvements were implemented by reverting flaky Flat DB workflow changes to restore reliable test runs across the suite.
