Harmony

Harmony aims to offer a high-throughput, low-latency, and low-fee consensus platform designed to power decentralized economies of the future.

Harmony is a fast and secure blockchain for decentralized applications. Our production mainnet supports 4 shards of 1000 nodes, producing blocks in 8 seconds with finality.

Our Effective Proof-of-Stake (EPoS) reduces centralization while supporting stake delegation, reward compounding and double-sign slashing.

Harmony has transcended the blockchain trilemma by bringing the best research to production. Sharding is proven to scale blockchains without compromising security and decentralization.

We divide not only our network nodes but also the blockchain states into shards, scaling linearly in all three aspects of machines, transactions and storage.

To prevent single shard attacks, we must have a sufficiently large number of nodes per shard and cryptographic randomness to re-shard regularly. Each shard has 250 nodes for strong security guarantee against Byzantine behaviors. We use Verifiable Random Function (VDF) for unbiasable and unpredictable shard membership.


We use Boneh–Lynn–Shacham (BLS) constant-sized signatures to commit blocks in a single round of consensus messages. We achieve 8-second block time with view changes in production against adversarial or unavailable leaders.

Harmony Mainnet was launched in June 2019. Our network has produced 10M+ blocks with 20k+ transactions in publicly traded, native ONE tokens.

Harmony has innovated on the battle-tested Practical Byzantine Fault Tolerance (PBFT) for fast consensus of block transactions. Our Fast BFT (FBFT) leads to low transaction fees and 1-block-time finality in Harmony Mainnet.

How do I buy cryptocurrency?

While some cryptocurrencies, including bitcoin, are available for purchase with U.S. dollars, others require that you pay with bitcoin or another cryptocurrency.

To buy cryptocurrencies, you’ll need a “wallet,” an online app that can hold your currency. Generally, you create an account on an exchange, and then you can transfer real money to buy cryptocurrencies such as bitcoin or ethereum.

Coinbase is one popular cryptocurrency trading exchange where you can create both a wallet and buy and sell bitcoin and other cryptocurrencies.
