From YouTube: Harmony 2023: Uniform Scaling & Onchain Security (Oct 10, 2022 All Hands)

Description

http://harmony.one/2023

Harmony is a scalable and secure blockchain. Our mainnet is live with state sharding since 2019 June and with open staking since 2020 May. Harmony achieves 2-second transaction finality with 4 shards, 250 nodes each, 25.3K onchain delegators, 60% liveness slashing, sub-second leader rotations.

Toward 2023, we are developing 1-block composable cross-shard transactions; validator resharding every 18-hour epoch with gradual state sync; and, account abstractions for smart wallets with social recovery but no central custodians or fee forwarders.

Firstly, Harmony supports uniform scaling, meaning that our shards grows linearly and boundlessly with transaction demands. Our nodes, states, transactions are each cleanly divided with secure synchronization with the beacon shard.

Secondly, Harmony supports onchain security, meaning that our delegators, bridges, wallets minimize trust assumptions besides malicious validators. Our end-to-end security relies only on the core protocol and smart contract execution – without risking censorship from colluded entities, suffering any single point of backend failure, sidestepping storage of authentication credentials, or leaking identifiable information.

At peak, Harmony’s protocol achieved 500 transactions per shard per second in production, our elastic endpoints served 800M requests per day – with our network accruing $1.41B total value locked, $1.48B stakes, 162 validator pools, 120 active apps, 75 DAO governors, 371K monthly active users, and 656K total wallets.

Harmony is Ethereum-compatible and supports 1. DeFi (Aave, Curve, Frax, Sushi, Tranquil, Stably, StakeDAO); games (DeFi Kingdom, DeFira, Mercury Forge); 2. NFT (Bored Apes, Animoca, Atari, MAD, .country domains), 3. DAOs (Gnosis, Snapspot, Aragon); 4. middlewares (Chainlink, Graph, Covalent, DappRader, Pocket Networks, Chainsafe, Hummingbot); 5. bridges (LayerZero, Datachain, Celer, Trustless BTC); 6. gateways (Wyre, Transak, MoonPay, Simplex); 7. exchanges (Binance, Huobi, Kucoin, Crypto.com, OKX); and, 8. wallets (Metamask, Ledger, Trust, 1Wallet).
In 2023, besides protocol development mentioned above, Harmony is driving adoption via games (wallet integrations, tournament ecrows, embedded marketplaces) – as well as impact via community (social curation, creator-fan economy, seasonal governance) and cross-chain via partners (chain-agnostic toolings, zero-knowledge-proof bridges, modular data availability).
