Ethereum 2.0 will merge in early 2022 | Vitalik Buterin and Lex Fridman

TL;DR

The process of merging the Ethereum 1.0 chain (proof of work) and the beacon chain (proof of stake) involves launching the proof of stake chain first, allowing it to mature and gain ecosystem support, and then transitioning the activity from the proof of work chain to the proof of stake chain.

okay let's talk about this uh wonderful process of merging okay so there's the main net which is the ethereum 1.0 chain or the ch what should we say the chain that uses proof of work as a consensus mechanism and then there is uh what is it called the the beacon chain that uses the uh the the proof-of-stake mechanism and i believe the beacon has bee...

Key Insights

• ⛓️ The merge involves launching and maturing the proof of stake chain before transitioning the activity from the proof of work chain.
• ⛓️ The merge will result in a seamless upgrade for users, as the old chain will be embedded inside the new chain.
• 🥹 The new chain will not hold information from the past transactions of the old chain, but separate protocols can be used to retrieve historical information.
• 😀 The merge has faced delays due to the underestimated technical complexity, but the community is strongly in favor of the proof of stake switch.
• 🚨 A realistic timeline for the merge is early 2022, but an optimistic case suggests it could happen this year.
• 🏣 The recent online hackathon, Rayonism, focused on testing the post-merge Ethereum chain, while the current focus is on testing and auditing the transition process.

Questions & Answers

Q: When will the proof of work and proof of stake chains merge?

The merge will happen in the future, but an exact timeline is uncertain. Early 2022 seems realistic, but it may extend beyond that.

Q: What is the process of the merge?

The merge involves embedding the old proof of work chain inside the new proof of stake chain, creating a chain within a chain. This allows for a seamless upgrade for users, as they don't need to switch chains.

Q: Will the new chain contain all the information from past transactions?

No, the new chain will not hold information from the Ethereum chain before the merge. Users and applications can retrieve historical information through separate protocols like the graph or customized search protocols.

Q: Why has the merge taken longer than expected?

The technical complexity of creating a successful proof of stake chain and figuring out the transition process has been underestimated. However, there hasn't been much social complexity or drama surrounding the merge.

Summary & Key Takeaways

• Ethereum has two chains: the main net (proof of work) and the beacon chain (proof of stake).

• The proof of stake chain was launched in December 2020 and has been running independently for six months to ensure its maturity and ecosystem support.

• The merge will happen in the future, where the activity from the proof of work chain will be moved to the proof of stake chain, eliminating the proof of work side completely.
