Ropsten’s proof-of-work chain was successfully merged with Ethereum proof-of-stake beacon chain.

An important milestone in Ethereum’s journey toward a new proof of stake (PoS) consensus mechanism has finally arrived with the Merge. Proof-of-work (PoW) is Ethereum’s 1.0 current method of generating new ether.

The process of adding new blocks to the blockchain will be taken over by validators who have staked the required 32 ETH once Ethereum switches from PoW to PoS.

The Beacon Chain is currently running alongside the PoW chain. It is the PoS coordination chain that already has validators creating and approving new blocks in tandem with the PoW execution chain. The two chains will merge and Ethereum will continue as a PoS blockchain once the PoS chain has been adequately tested and secured.

Ethereum’s code is so complex that it needs to be tested on multiple test networks. In preparation for the Mainnet Merge, developers will use the results of this first test to guide their work in the future.

What Is Ethereum 2.0?

It’s been a long time coming, but Ethereum 2.0 is finally coming to fruition in 2022.

The Ethereum community has long discussed the possibility of a version 2.0 of Ethereum. The implementation of a Proof of Stake consensus mechanism, which moves the network away from its existing Proof of Work architecture, makes Ethereum 2.0 a particularly significant upgrade when compared to previous upgrades.

Block rewards, which are distributed to miners who successfully mine a block, serve as a measure of the time and money that miners must spend running hardware and using electricity on PoW chains. In order to compromise a well-established PoW blockchain like Bitcoin or Ethereum, an individual would need an enormous amount of computational power that may not even exist.

Proof of Stake will reform the crypto-economic incentive structure for validating the blockchain.

What is Ethereum Merge Testing, and why is it important?

Prior to the Mainnet Merge, Ethereum’s developers are using a testing infrastructure to evaluate the network’s mechanics and the readiness of its clients.

In order for the network to progress, it is essential that developers find bugs in the code that would otherwise go unnoticed by the devnets.

It was on May 5th that the latest shadow fork took place, which included new tests on Merge syncing, which revealed a few minor but fixable issues.

Merge testing, like many aspects of the Ethereum network, is a collaborative and critical effort.
