We met at ETHDenver or one of the great side events. corpus.core builds Ethereum core technology. With the CORPUS CORE COLIBRI STATELESS client, we provide a Trustless Stateless Ultra Light Client. Never again trust data from any RPC provider. With colibri-stateless, every data can be validated by trustless proofs. No sync is needed, no state is stored. It is so small that it runs on any IoT hardware, mobile and web apps, etc. This is how blockchain access is meant to be. More information and a first prototype: https://github.com/corpus-core/c4
