ETH 2.O

Ethereum’s Merge—the blockchain’s much-anticipated transition from its current proof-of-work (PoW) mechanism to a proof-of-stake (PoS) consensus algorithm—will be one step closer today if the planned trial upgrade on the Ropsten public testnet went as planned .

First rolled out in 2016, Ropsten is Ethereum’s oldest testnet that allows for blockchain development testing before deployment on the mainnet. Similar to other testnets, it is identical to the mainnet, with the key difference that no “real” funds are at risk if any technical issues occur.
