Tendermint Core Architecture Decision Records (ADR)
Here we record all high-level architecture decisions in the Tendermint Core project. All implemented ADRs in this list naturally affect CometBFT, since CometBFT is a fork of Tendermint Core as of December 2022.
This list is currently frozen and kept for reference purposes. To add new ADRs, please do so for CometBFT here.
