Road To Devcon - I

Reading Ethereum

In 2026, Ethereum turns 11. Eleven years since a genesis block turned an experiment into the base layer for a global builder economy. To mark it, we're running 11 weeks of Build Battles, one for every year of Ethereum's life, every weekend as part of Road to Devcon.

New dev challenge drops every weekend, welcome to the first chapter.

Throughout ancient Indian dynasties, royal decrees, tax records, and grand land grants were etched into Tamra-Patra (copper plates) or carved into temple rock faces using specialized Brahmi scripts.

Today, the Ethereum blockchain functions as our digital Tamra-Patra, an unyielding, immortal ledger recording every transfer of value and agreement.

This weekend, you would be building a focused mini block-explorer around one lens, e.g. gas-usage trends, failed transactions, or MEV-adjacent activity using only direct RPC calls, no third-party indexer. A raw-data decoder that turns calldata and event logs into human-readable transaction stories in real time, via RPC subscriptions/websockets rather than a pre-built API.

FAQ

Frequently asked questions

How does scoring work?

Submissions are scored by an AI judge against each problem's judging criteria. Your best problem score becomes your battle score, and ratings update once results are finalized.

Can I work in a team?

No, this is a solo build battle.

What do I need to submit?

A GitHub repository with your working project. You can keep updating your submission until the build window closes.
