yesterday i wrote about zk proofs which separate execution from validation and verification. so what are blockchains moving towards beyond L2s?

another 🧵👇

after we solve zk rollups, development is far from done. there's one looming problem: data availability. when everything in the world is run on a blockchain, where/how do you store the transaction info while remaining decentralized?

there are a few projects tackling this, like @ethswarm and @CelestiaOrg, but research is even more bleeding-edge than ZKs are- i expect the narrative to shift to DA a few years from now.

ethereum is currently working on state expiry and statelessness, which means that the average node wouldn't have to retain a copy of the entire blockchain, but it's still several years away.

under the hood, the blockchains that will survive will look more like a network of moving parts (rollups, settlement, validiums, volitions, consensus) operating interdependently instead of the current model. it's the only way to achieve worldwide-level scaling

as it stands now, ethereum will be the "spine" of this new blockchain architecture, with rollups, volitions, DA layers, etc running alongside and inheriting the security of the base layer

it will be a multichain future, but not in the way that people currently think of one. we already see that the EVM has become the standard for smart contracts and Solidity has become the default programming language for them

it will be hard to disrupt 5+ years of developer tooling, onboarding, documentation, and community. eth is the current blockchain standard

does this mean solana, avax, and the others cannot coexist? no, i believe they will end up as rollups eventually, or fade into obscurity-

as a L1 chain, why would you pay a lot of money to secure your chain (mining rewards, staking, etc) when buying ETH and checkpointing to it will be far cheaper and more secure?
