TLDR: Krypton Phase 3 was deployed on Thur Sep 24, 2020
What is Stacks 2.0?
Stacks 2.0 is a new layer-1 blockchain that uses Proof-of-Transfer (PoX) to connect to Bitcoin. Stacks 2.0 brings apps and predictable smart contracts to Bitcoin. Assets and contracts are secured by Bitcoin, and STX holders can earn BTC by participating in consensus. See an earnings calculator and a community intro video).
When is Stacks 2.0 mainnet launching?
It’s natural to want a date to look forward to and we’re always working to improve our ability to make accurate estimations, but we’re much more concerned with ensuring a successful launch.
With Phase 3 (Krypton) going live last week, 90% of the implementation outlined in the whitepapers has been implemented. We won’t rush something out just to hit a date, but rest assured everyone is working extremely hard to make it happen soon. The best engineering estimate is as follows:
a) Stacks 2.0 will certainly not launch before Oct 31st (Xenon will not finish by then).
b) Stacks 2.0 mainnet readiness will likely not go beyond Dec 15th 2020.
This gives an estimated range of 6 weeks (Nov 1st to Dec 15th). Mainnet readiness means that there is a release that can be deployed by miners and it passes all checks. Miners will decide the exact launch date.
We’ll do our best to give everyone a 2-4 week heads up before the launch is ready to be adopted by independent miners. The advance notice would give developers, exchanges, and others a chance to potentially integrate before the public launch and give the community time to plan an event around the launch.
What happens after Krypton?
We're in the home stretch. Xenon the Stacks 2.0 Phase 4 has started! STX miners and stackers will be able to mine and stack on the testnet at this point. Microblocks is one feature that will be implemented in Phase 4 in addition to testing. Here is a status visual from testnet.blockstack.org (as of Fri Sep 25th):
OK, so what is the status of Phase 4 (Xenon)?
Phase 4 (Xenon) is currently in the beginning stages of implementation.

Thank you again to all those contributing to Stacks 2.0 and for your patience as we diligently work together toward a quantum leap for the ecosystem.
