Zero-Knowledge Proofs (ZKPs)
- What are ZKPs: Cryptographic proofs that verify a statement is true without revealing the underlying data. 'I can prove I'm over 18 without showing my birthdate'
- zk-SNARKs: Succinct Non-interactive Arguments of Knowledge — small proof size, fast verification, but require trusted setup. Used by Zcash, zkSync
- zk-STARKs: Scalable Transparent Arguments of Knowledge — no trusted setup, quantum-resistant, but larger proofs. Used by StarkNet
- ZK Rollups: Use ZKPs to scale Ethereum — batch thousands of transactions off-chain and post a validity proof on-chain. zkSync, StarkNet, Polygon zkEVM
- Privacy Applications: ZKPs enable private transactions (Zcash), private identity verification (Polygon ID), and private voting (MACI)
- ZK Machine Learning: Prove that a specific ML model produced a specific output without revealing the model or input data. Emerging research frontier
Next-Generation Technologies
- Account Abstraction (ERC-4337): Smart contract wallets that replace EOAs — gas sponsorship, social recovery, batched transactions, session keys. Makes crypto usable for normal people
- Modular Blockchains: Separate execution, data availability, consensus, and settlement into specialized layers. Celestia (DA), Ethereum (settlement), Rollups (execution)
- Intent-Based Architecture: Users specify WHAT they want (swap 1 ETH for max USDC) not HOW — solvers compete to find the best execution path. UniswapX, CoW Protocol
- Restaking (EigenLayer): Reuse staked ETH security for other protocols — validate oracle networks, bridges, and new chains with existing ETH stake
- Data Availability Sampling: Verify data is available without downloading it all — enables massive scalability. Danksharding, Celestia, EIP-4844 (blobs)
- Fully Homomorphic Encryption (FHE): Compute on encrypted data without decrypting — enables private smart contracts. Zama, Fhenix, Sunscreen
