Devcon 2024 in Bangkok has come to a close, and we at Amber Group are proud to have participated in such an important event for the Ethereum community. This year, our team shared cutting-edge developments in key areas of the Ethereum ecosystem, from transaction querying and node optimization to security research.

For those who couldn’t attend, here’s a recap of the key highlights:

JSON-RPC Enhancement in Geth: Optimizing Transaction and Trace Querying 

Our presence at DevCon kicked off with a session focused on improving how developers interact with Ethereum’s execution clients. We shared updates that make it easier to track and analyze Ethereum transactions with more precision.

In this session, we introduced major improvements to Ethereum’s execution clients (Geth) by extending the JSON-RPC API to include a new `trace_*` namespace and the method `eth_getTransactionBySenderAndNonce`. These updates are designed to enhance transaction and trace querying capabilities, providing developers with a much-needed tool to analyze Ethereum transactions with greater precision.

We leveraged Geth’s live tracer capability and its built-in tracers to support real-time indexing of transaction traces. This enhancement allows for querying with O(1) time complexity, significantly reducing the CPU and memory usage compared to the legacy debug RPC methods. These enhancements allow for deeper insights into the behavior of transactions, which is invaluable for debugging, monitoring, and building complex decentralized applications (dApps). These features significantly improve the ability to trace, validate, and audit transactions, giving developers the data they need to better understand the state of the Ethereum network and their applications.
