Accelerate Your Moonbeam Development with Particle SDK: Build Scalable and Efficient dApps in a Seamless Web3 Environment


Harmony is a high-throughput, low-latency, and low-fee consensus platform designed to power decentralized economies of the future. It leverages sharding technology to enable seamless scalability and secure transaction processing. Harmony aims to create a highly performant and energy-efficient platform for building and deploying decentralized applications (dApps) and facilitates the creation of cross-chain and cross-platform solutions.

Key Features and Benefits

  • High Throughput: Harmony's sharding technology enables high throughput and fast transaction speeds, which is beneficial for developers building responsive and efficient dApps.

  • Scalability: Harmony's sharding and staking mechanisms allow for seamless scalability, ensuring that the platform can grow alongside the number of applications and users.

  • Cross-Chain Compatibility: Harmony's bridge infrastructure connects with other major blockchains, such as Ethereum and Binance Smart Chain, promoting cross-chain collaboration and asset transfers.

  • Eco-friendly Consensus: Harmony's Effective Proof-of-Stake (EPoS) consensus mechanism reduces energy consumption compared to traditional Proof-of-Work (PoW) systems, making it an environmentally friendly platform.
