7/ Watch ALEX | ZK’s full keynote from ETHDenver 👇🏽

ℤ𝕂 𝕚𝕤 𝕥𝕙𝕖 𝔼𝕟𝕕𝕘𝕒𝕞𝕖 We’ve memed it into existence, but what does it actually mean? @gluk64’s ETHDenver talk breaks it down 🧵

2/ The internet doesn’t run on a single server. It's a global system with infrastructure owned and operated by people you've never heard of. Encryption helps secure the internet from most malicious actors despite many opportunities for interference. Similarly, Web3 won’t run on a single chain. Right now, blockchains are evolving into a more complex network — L2s, hyperchains, DA, bridges, etc. Each new component creates an opportunity to censor. ZK Proofs preserve trustlessness as Web3 goes mainstream.

3/ With Web2, communication protocols like TLS & SSL authenticate messages to prove communication wasn’t altered. HTTP → HTTPS But blockchains aren’t just communicating. They’re also transacting. Blockchains take an input state, perform some computation, and produce an output state. When the multichain future goes parabolic, we need to prove this computation wasn’t altered at any point. Similar to how TLS/SSL gave us the integrity of communication, ZK Proofs give us the integrity of computation. HTTP → HTTPZ

4/ ZK lets us prove and verify computation across chains because of recursion. Transaction proofs are combined over and over again until you have an entire proof of a block. That block can then be recursively proved with blocks from other chains, all laddering up to a single proof. This single proof, which is fast and cheap, can verify the computational integrity of every single transaction that settles on Ethereum. This provable trust across chains is how we verifiably scale Ethereum beyond just a base layer and a couple of slightly interoperable L2s.

5/ ZK is the Endgame to verifiably scale Ethereum

6/ TL;DR → Web2 doesn’t run on a single server. Web3 won’t run on a single chain. → A complex system introduces compounding trust assumptions 🤮 → Web2 uses TLS/SSL protocols as its cryptographic backbone to verify communication → Web3 will use ZK as its cryptographic backbone to verify computation → Recursive ZK Proofs can verify computation across multiple chains letting users transact on any chain with no new trust assumptions → ZK Proofs on @zkSync are how Ethereum will verifiably scale without sacrificing trustlessness.
