Ethereum 2.0 Merge, what then?

[nikola-bozin]

So, lets say ethereum merge happend. What will happen to the solidity, to the web3js library, or ethers,will they change?
Will transaction parameters stay the same?
Lets say merge happend in block 1000000, would we be able to read transactions in blocks that are for example 55555 or any number below 1000000?
What will happen to the "back-end" side of solidity and blockchain programming? What will change from current way of programming in solidity and javascript/python?

I hope you understand what i would like to know...

Ethereum will shift from PoW to PoS. And no, I am pretty sure Solidity will exist - smart contracts is arguably the most important innovation Ethereum brought forth.

Vitalik has always advocated for soft-forks and simplicity unless deemed necessary as was the case in the DAO hack - so, you do not need to worry.

Well, i know it will shift to PoS, but that does not answer my question at all.

How will shifting to PoS affect making solidity smart contracts and writing web3js/ethersjs codes, and making raw transactions, and similar stuff?

Read again, it will not. Vitalik has always advocated for soft-forks and simplicity unless deemed necessary as was the case in the DAO hack - so, you do not need to worry.

It has everything you need to know https://ethereum.org/en/upgrades/merge/#:~:text=Dapp%20and%20smart%20contract%20developers
A little more details https://blog.ethereum.org/2021/11/29/how-the-merge-impacts-app-layer/

But in shorts:

1. DIFFICULTY OPCODE change
2. Exact 12 seconds block time
3. New block structure
4. New concept for confirmed transactions

Thanks! This clarified some things!
