Cosmos Testnets

This repo collects the genesis and configuration files for the various Cosmos testnets. It exists so the Cosmos-SDK repo does not get bogged down with large genesis files and status updates.

Getting Started

To get started with the latest testnet, see the docs.

May 31, 2018, 2:00 EST - Testnet Halt

• A validator equivocated last week and Evidence is being rampantly gossipped
• Peers that can't process the evidence (either too far behind or too far ahead) are disconnecting from the peers that sent it, causing high peer turn-over
• The high peer turn-over may be causing a memory-leak, resulting in some nodes crashing and the testnet halting
• We need to fix some issues in the EvidenceReactor to address this and also investigate the possible memory-leak

May 29, 2018 - New Release

• Released v0.17.3 with update for Tendermint v0.19.6
