Eth1.0 Merge to Eth2.0

March 17, 2022

5-Minute Read

Review

In December of 2020, ETH went online with the 2.0-0 stage beacon chain, the underlying application of ETH 2.0 Proof of Stacking (pos), which is not like the ETH 1.0 main chain that is running now, there is no smart contract nor account management on Beacon Chain, its main function is the 2.0 consensus mechanism, users protect the security of the whole 2.0 main network by pledging. In stage 0, users can only pledge ETH tokens and cannot run contracts or transfer money.

Merge

In March 2022 ETH developers launched the kiln ETH2.0 merge test network, the current 1.0 main network will be merged into the 2.0 Beacon Chain, this is done to end the 1.0 above the pow consensus mechanism, and a full transition to Pos, using ethereum.org official expression means like a spaceship docking, 1.0 is no longer capable of long-distance interstellar voyages, so the developers designed a new engine for 2.0, where 1.0 will dock and merge with 2.0 ships and sail deeper into the universe. When the merger is complete, the ETH 1.0 mainnet will merge with Beacon Chain to become the ETH main chain, and will move to Pos (Proofs of Stacking) instead of Pow (proofs of work). The main-net brings smart contracts into the Proof-of-stacking system and imports all historical data and current status from ETH 1.0, ensuring a smooth transition from 1.0 to 2.0 for ETH holders and users. when the merge occurs, the validator node will take over the mainnet and the miner will no longer be needed.

Operation Guidelines

I chose the lighthouse beacon chain as my own validator node, the following is the specific yaml file for the operation in kubernetes, you can also refer to the relevant website for deploying the node.
