The deposit contract for ethereum 2.0 is hopefully to launch this spring in one of the many ethereum related events.

“Formal verification of the contract was just released,” Danny Ryan, the ethereum 2.0 coordinator said, adding:

“This work needs to be out for public review and comment for at least 6 weeks before we launch the deposit contract.

Barring no major issues uncovered, I think we should do it at one of the major events coming up this Spring.”

Six weeks from now puts us around mothers’ day in March, so a number of events do not qualify. The events previously listed by Ryan are:

ETHDenver – Denver, USA – Feb 14 to Feb 16 – with eth2 specific bounties!

Stanford Blockchain Conference – Stanford, USA – Feb 19 to Feb 21

Eth 222 – Stanford, USA – Feb 22

ETHLondonUK – London, UK – Feb 28 to March 1

ETHCC – Paris, France – March 3 to March 5

EDCON – Vienna, Austria – April 3 to April 7

Ethereal Summit – New York, USA – May 8 to May 9

ETHNewYork – New York, USA – Dates TBD

The February ones are out, so London won’t get the privilege. Paris maybe, but Vienna would be quite a place for the launch, otherwise the artsy ethereal summit in New York.

They want multi-client testnets out first so presumably that means they’d be out by April or May with Justin Drake, an ethereum researcher, estimating another 2 months will be needed for the multi-testnet, placing us in April.

He however estimates three months for the deposit contract launch, placing us in May.

So Vienna might be honored with the testnet genesis block launch, a country very friendly to this space with Edcon one of the better conferences.

While New York gets the deposit contract, both key milestones with the above timeline suggesting July 30th is the aimed mainnet launch.

That’s tentative however, we won’t know until closer to the time, but Ryan says he is “aiming for [launching the deposit contract] at one of the major events this spring.”

In related news, there seems to be consensus on phase 1.5 with Ryan stating: “Pretty much everyone I’ve spoken with — client teams (eth1 and eth2), protocol researchers (eth1 and eth2), community members, users, etc — wants to see this a reality.”

While Drake says phase 0 is 99% finished. “Phase 1 is close to done, like 90% done,” he says.

So it’s happening, with phase 1.5 being a key milestone after the Proof of Stake (PoS) blockchain launches hopefully this summer.

“Once we have Phase 1 client implementations prototyping a phase 1.5 will be a major priority,” Ryan said.

Phase 1.5 as you might know merges the current Proof of Work (PoW) blockchain into the new Beacon PoS chain with that being a huge event as it will reduce new supply to basically zero and will be the beginning of the end of the transition period with that phase 0 shard then giving way to another 63 shards and eventually an aimed 1024 shards for massive capacity in a scalable and decentralized way.
