# Cosmos Testnets

This repo collects the genesis and configuration files for the various Cosmos
testnets. It exists so the [Cosmos-SDK](https://github.com/cosmos/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](https://cosmos.network/docs/getting-started/full-node.html).

## *June 10, 2018, 8:30 EST* - Gaia-6001 consensus failure

- Includes bug fix for declaring candidacy from the command line

## *June 8, 2018, 23:30 EST* - Gaia-6001 is making blocks

- +2/3 of the voting power is finally online for Gaia-6001 and it is making
  blocks!
- This is a momentous achievement - a successful asynchronous decentralized
  testnet launch
- Congrats everyone!

## *June 8, 2018, 12:00 EST* - New Testnet Gaia-6001

- After some confusion around testnet deployment and a contention testnet
  hardfork, a new genesis file and network was released for `gaia-6001`

## *June 7, 2018, 9:00 EST* - New Testnet Gaia-6000

- Released a new `genesis.json` file for `gaia-6000`
- Initial validators include those that were most active in
  the gaia-5001 testnet
- Join the network via gaia `v0.18.0-rc0`

## *June 5, 2018, 21:00 EST* - New Release

- Released gaia
  [v0.17.5](https://github.com/cosmos/cosmos-sdk/releases/tag/v0.17.5) 
  with update for Tendermint
  [v0.19.9](https://github.com/tendermint/tendermint/releases/tag/v0.19.9)
- Fixes many bugs!
    - evidence gossipping 
    - mempool deadlock
    - WAL panic
    - memory leak
- Please update to this to put a stop to the rampant invalid evidence gossiping
  :)

## *May 31, 2018, 14:00 EST* - New Release

- Released gaia
  [v0.17.4](https://github.com/cosmos/cosmos-sdk/releases/tag/v0.17.4) with update for Tendermint v0.19.7
- Fixes a WAL bug and some more
- Please update to this if you have trouble restarting a node

## *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
- Fixes fast-sync bug
- Please update to this to sync with the testnet
