CSS on my blog reduced from 5875 lines to 233 lines. https://vitalik.eth.limo/css/main.css Today is a great day for simplification. All software (incl law) should do this more.

But also, I suspect that if we just made an option in HLLs for devs to use SSZ as ABI, quite a few would start taking up the offer just for byte-efficiency reasons alone. ABI has big downsides (the 32 bytes)

If I had to lose one of the three to converge it would probably be the ABI - at least it's not consensus code, and as I wrote SSZ and ABI are pretty similar

Caring about simplicity is, like decentralization, a short-term cost for the sake of benefits that do not appear immediately. But in the long term, it will be worth it. Let's make each part of the ethereum spec a place where things like this can happen: https://x.com/leonardoalt/status/1917583664755671408

We can also simplify the protocol by making sure that sub-protocols are shared as much as possible: there should ideally only be one way we do X, across the consensus, execution and other layers. Potential targets: erasure coding, serialization, trees.

A backwards-compatibility strategy: move the old EVM from consensus-critical client code, to a RISC-V implementation. Existing contracts would continue working as-is.

Now we get to the execution layer. This is one of my motivations for proposing the RISC-V (or other ZK-friendly) VM shift.

The effort to revamp Ethereum's consensus, historically called the beam chain, includes many opportunities to simplify consensus, while also increasing efficiency and security.

One of the best things about Bitcoin is how simple it is. This simplicity has lots of benefits. Let's bring those benefits to Ethereum.
