Cryptography Notes/Resources

Non-Technical

  • Aggregated Blockchains: A New Thesis → Polygon feb 24
  • Electronification, Trading, and Crypto → Uniswap → Decentralization.
  • A Cambrian Explosion of Crypto Proofs
    • Symmetric Encryption is Quantum proof?
    • Takeaway: asymmetric circuit-specific systems (Groth16) are shortest, shorter than all asymmetric universal ones, and all symmetric systems.
    • Post Quantum Commitment Scheme → Merkle Trees.
  • A Brief History of Money
    • A medium of exchange is the asset we use to directly settle transactions. This is the easiest hurdle to clear. You can use Starbucks rewards points to buy a latte, so Starbucks points function as a medium of exchange. But of course, Starbucks points aren't a great store of value—people know this instinctively and don't store their savings into Starbucks points. This is not just because it's impractical; people are aware that Starbucks might modify their rewards program to devalue these points, and there's not a stable market for selling saved up points. → The US dollar can also be devaluated by some “Starbucks”.
    • Money is just a bubble that never pops.
  • The Cypherpunks
  • Satoshi Nakamoto
  • SNARK proving ASIC

Technical

ZK-Proofs:

Ethereum’s ZK rollups:

  • Proof generation and verification: ZK-rollup operators must produce validity proofs for transaction batches, which is resource-intensive. Verifying zero-knowledge proofs on Mainnet also costs gas (~ 500,000 gas).
  • An advantage of zero-knowledge proofs is that proofs can verify other proofs. For example, a single ZK-SNARK can verify other ZK-SNARKs. Such "proof-of-proofs" are called recursive proofs and dramatically increase throughput on ZK-rollups.
  • ⚠️Producing validity proofs requires specialized hardware, which may encourage centralized control of the chain by a few parties.
