Stephen Tse’s talk on 12/7 Wed in Palo Alto. First, uniform scaling on our Shard 1 – versus Layer 2 (Arbitrum), App chain (Cosmos), ZK Proofs (0xPARC). Second, economics games on our Web3 identity – about Internet domains (.country), crypto names (.1), radical markets (ONE).



Harmony 2023: Uniform Scaling on Shard 1 & Economics Games on

🚀 Uniform Scaling (Shard 1)

Harmony 2023: Uniform Scaling & Onchain Security

1. Layer 2 (Arbitrum)

  1. Single sequencers (Optimism) Our mainnet with 1000 nodes among 4 shards, live since 2019 June, grows linearly and boundlessly with transaction demands. (Harmony on sharding, Delphi Digital on rollup, Messari on rollup)
  2. Fraud proofs (Rainbow). Our consensus algorithm achieves 2-second finality & sub-second leader rotations – via view changes, 60% liveness slashing, constant-sized signatures. (Common Prefix’s audit, Bridge exploits, Ethereum’s design choices)
  3. Account abstractions (Near) Our network accrued $1.41B total value locked, $1.48B stakes, 120 active apps, 75 DAO governors, 371K monthly active users, 656K total wallets. (Harmony’s Q3, Messari’s annual thesis, Ethereum’s roadmap)

2. App chains (Cosmos)

  1. Data shards (Celestia) Our open staking, live since 2020 May, achieved 500 transactions per second (TPS) in production with state staking and beacon chain synchronization. (Celestia’s modular architecture, Data availability, ATOM 2.0)
  2. State prune (Ethereum) Our elastic endpoints served 800M requests per day – soon with 1-block composable cross-shard transactions & validator resharding with gradual state sync. (Delphi Digital’s analysis, Solana’s downtime, Near’s dynamic sharding)
  3. Stateless clients (Mina) Our validator delegation and reward compounding are fully onchain – supporting 162 pools and 25.3K delegators, scalable to hundreds of thousands. (Recursive proofs in OCaml, Lido’s liquid staking, Proof-of-Solvency)

3. ZK Proofs (0xPARC)

  1. Keyless wallets (Argent) Our ResearchDAO implements smart-contract wallets with SmartOTP (smart-contract wallet with One-Time-Password) via Google Authenticator. (Timeless’s social wallet, Zindros’s rate limiting, **Loopring’s social recovery)
  2. Trustless bridges (Succinct Labs) Our research paper on gas-efficient bridge with FlyClient & Merkle Mountain Range achieves logarithmic inclusion proofs – along with our Bitcoin bridge. (Horizon with Flyclient, Gnosis<>Ethereum bridge, Polygon’s Q3 on ZKP)
  3. Strategy games (Dark Forest) Our zkDAO explores nonbiasable randomness as Harmony’s virtual machine extensions – for game tournament escrows & verifiable fairness as Fog of War. (Harmony’s zkDAO, ZKU’s Blue Forest, 18xx game genre, Messari’s ZKP overview)
