A year ago today was the world’s first decentralized launch of a proof-of-stake network, the Cosmos Hub. The memorable “go-live date” started on March 13th, 2019 at 23:00 UTC with validators and community members participating from all over the world. The Cosmos Hub mainnet launch was two years in the making and the first phase of a three-phase rollout of the Cosmos Network, aka the “Internet of Blockchains”.
The next two phases of the Cosmos Network were (2) enabling ATOM transfers — completed in April 2019 — and (3) a production-ready Inter-blockchain Communication (IBC) protocol. IBC is the remaining element that we’re still working on. The IBC spec was determined in June 2019 by members of Agoric, All in Bits (dba Tendermint), and the Interchain Foundation teams. A demo and public IBC testnet will be coming soon — stay tuned.
The Cosmos Hub has had an incredibly busy year that includes:
- Three successful mainnet launches, culminating in Cosmos Hub-3
- Multiple millions of blocks validated over three mainnets
- A decentralized community of 125 mainnet validators
- An average of ~7s per validated block
- 15 on-chain governance proposals created and voted on
- 300,000+ ATOMs added a community pool
A grateful thank you to every Cosmonaut who played a part in building, promoting and launching the Cosmos Hub. The community’s dedication and continued support over the past year is unique to the Cosmos project. Let’s spread some cheer by remembering all the hard work and excitement leading up to launch and the celebrations we shared in the weeks following it.
Wishing Cosmos and everyone a happy anniversary, tweet your favorite memory of Cosmos and make a wish — #Cosmosturns1
Here’s a short walk down memory lane with some of the team’s memorable moments from mainnet launch.
In the weeks and days leading up to the Cosmos mainnet launch, the community was preparing and building momentum.
After -months- of preparation, and many a sleepless night we are so excited for the opportunity to be a genesis validator on the @cosmos Network. Get ready cosmonauts, because this rocketship is about to blast off! The FUTURE is at STAKE! #cosmoslaunch #Cosmos #Firmamint
Remember all the testnets? The numerous Gaia testnets helped prepare the community for mainnet launch.
Goodbye gaia-13001, hello cosmoshub-01! #cosmoslaunch

Finally, the moment of launch was near. The team wanted to share the moment and celebrate with the community.
Ready and comfortable for @cosmos #cosmoslaunch! God Speed #COSMOS team, may the $ATOM be created.
Our live event was hosted by Chjango Armstrong and Jack the Gentlemen with many validators joining in the celebration. The ‘excitement was palpable’ when Cosmos Hub validators were validating blocks just five minutes after genesis.
In the words of Sunny Aggarwal “we have a public blockchain, this is insane.”

Many Cosmonauts will remember the suspenseful “Block 17.” Minutes after going live, the Cosmos Hub was stuck on block 17 when a validator went offline, halting the network because less than 66.67% of staked ATOM were left online. The uncertainty was over when, moments later, the community rallied to bring online some more voting power. However, “Block 17” lived on as the winning costume at the Berlin Cosmos Launch Party.
Consider delegating @cosmos ATOMs to Karoly, absolute winner in #cosmoslaunch costume party at @fullnode_berlin for accurately representing “Block#17”, feat. @Jack_Zampolin Help dencentralise the @cosmos Hub & let’s pass a governance proposal so @interchain_io delegates to him!
Finally, there was a full crew on the call and even family members were joining in on the celebration. The live event concluded with a discussion on what people hoped to see happen in the Cosmos ecosystem.
O n March 14th, the Twittersphere was abuzz with excitement about the Cosmos launch.
Very grateful to have been a part of this journey. Hope I can continue contributing to this amazing ecosystem as it grows beyond the Hub. One small step on a long exciting path #cosmoslaunch
I just wanted to shout out a big Thank You to our team at @tendermint_team and @interchain_io and the @cosmos community and supporters, for pushing forward and making it all possible and meaningful. To the Cosmos!
Today marks the day when @cosmos launch took over Twitter.Seeing the entire community come together and congratulate @tendermint_team for their extraordinary work gives all of us who have been cheering from the sidelines, such a great sense of accomplishment. It just became real!
Then it was time for the global Cosmos community to party! We even had a throw your own party kit (TYOPK) to join in on the Cosmos launch experience.
Launch is over but the party’s just started 🍾🎊 Celebrate w/ Cosmonauts anywhere you are in the 🌏. Launch parties are coming to major blockchain hubs like SF, Berlin, NYC, Shanghai, Seoul, and you can even #TYOP. Share your experience 🚀#cosmoslaunch https://t.co/iIAV9EJmIf
Straight out of the #CosmosLaunchParty in Berlin! With @JamesMcDowallCX and team representing us, @Sentinel_co looks forward to participating in launch parties of various Hubs and celebrate many more milestones of @tendermint_team & the @Cosmos Network #CosmosLaunch #blockchain
Jin Kwon was sent on a world tour across many time zones to celebrate at all the Cosmos launch parties happening around the globe.
Thanks for all the memories and for sharing this journey with us! We could not have done it without you! Let’s make the Cosmos ecosystem even better in 2020!

To the Cosmos and beyond!
