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, and 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 grow linearly and boundlessly with transaction demands. Our nodes, states, transactions are each cleanly divided into shards 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); 2. games (DeFi Kingdom, DeFira, Mercury Forge); 3. NFT (Bored Apes, Animoca, Atari, MAD, .country domains), 4. DAOs (Gnosis, Snapspot, Aragon); 5. middleware (Chainlink, Graph, Covalent, DappRader, Pocket Networks, Chainsafe, Hummingbot); 6. bridges (LayerZero, Datachain, Celer, Trustless BTC); 7. gateways (Wyre, Transak, MoonPay, Simplex); 8. exchanges (Binance, Huobi, Kucoin, Crypto.com, OKX); and, 9. wallets (Metamask, Ledger, Trust, 1Wallet).
In 2023, besides protocol development mentioned above, Harmony is driving adoption via games (desktop-mobile wallet sync, tournament escrows, 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).
(*We are actively writing this document and welcoming feedback. To be completed by 2023 Jan, with existing essays on leader rotation, state pruning, light clients).

Our base assumption is that demand for block space, similar to demand for computation, is elastic; the cheaper the block space, the more different kinds of computation are able to move on-chain. This means that no matter how fast a monolithic chain is, demand for blockspace is likely to outstrip supply, with costs rising over time.
For most other dApps, we would argue asynchronous composability is fine as long as there’s strong cross-chain tooling to port assets over and make the UX of interacting with different dApps seamless.
