Harmony crypto is an open and fast blockchain with a mainnet (an independent blockchain running its own network with its own technology and protocol) that was launched in 2019, operating Ethereum applications with a 2-second transaction finality while having a lower fee in its hundreds.
Harmony crypto’s network has produced over 30 million blocks with over 450 thousand transactions in publicly-traded, native ONE tokens.
The crypto operates on an open blockchain network through a safe bridge that provides a cross-chain asset transfer with multiple chains. It also enables creators to connect with their immediate community.
These secure bridges can connect any Proof-of-Stake and Proof-of-Work chains, and the current bridges for Ethereum and Binance Smart Chain secure millions of cross-chain assets.
Harmony crypto acts as a Proof-of-Stake (PoS) mechanism – which drastically reduces transaction time and is said to resolve scalability issues that are associated with blockchain networks – by utilizing a concept called “sharding” which has been proven to scale blockchains without compromising decentralization and security.
Its Effective Proof-of-Stake (EPoS) mechanism also reduces centralization and fairly distributes rewards to thousands of validators.
The crypto’s model provides validators with a predictable transaction return while ensuring that transaction fees are sorted out to prevent any issue that may lead to an automatic zero inflation.
It uses the Boneh Lynn Shacham (BLS) signatures which are stable-sized, to keep blocks in a single round of consensus messages.
Harmony crypto’s staking mechanism enables the compounding of reward and delegation, while also supporting total uptime yet, fully open participation and at the same time, penalizing elected but unavailable nodes and removing validators who double-sign, all with the help of its EPoS mechanism.
For Harmony crypto to prevent single shard attacks, it has to possess an adequate number of nodes per shard and random code to re-shard regularly.
Each shard has 250 nodes in order to boost security against Byzantine behaviors. It uses Verifiable Delay Function (VDF) for unpredictable and uncompromised shard membership.
In order to enable the fast consensus of block transactions, Harmony crypto has innovated the battle-tested Practical Byzantine Fault Tolerance (PBFT) which will lead to 1-block-time finality in Harmony mainnet and low transaction fees.
