Harmony

Key Technical Advantages:

Fully Scalable Sharding: Unlike other blockchain networks, Harmony implements sharding at multiple levels. Not only does it shard network communication and transaction validation, it also shards the blockchain state. This makes Harmony a fully scalable blockchain that can support a larger number of transactions and more complex decentralized applications. Secure Sharding: The sharding process in Harmony is secure due to the distributed randomness generation (DRG) process. This process is unpredictable, unbiaseable, verifiable, and scalable. Harmony also reshards the network in a non-interruptive manner, which provides protection against slowly adaptive byzantine adversaries. Efficient and Fast Consensus: Harmony uses a Proof-of-Stake (PoS) consensus mechanism which is more energy-efficient compared to Proof-of-Work (PoW) mechanisms. Its consensus is reached with a linearly scalable Byzantine Fault Tolerance (BFT) algorithm thatÕs 100 times faster than Practical Byzantine Fault Tolerance (PBFT). Adaptive-Thresholded PoS: The threshold of stakes required for a node to join the network is adjusted based on the total amount of staking. This prevents malicious actors from concentrating their power in a single shard. Additionally, the threshold is low enough to allow small stakers to participate in the network and earn rewards. Scalable Networking Infrastructure and Consistent Cross-Shard Transactions: Harmony uses RaptorQ fountain code and Adaptive Information Dispersal Algorithm to quickly propagate blocks within shards or across the network. It also uses Kademlia routing to achieve scalable cross-shard transactions. Harmony supports cross-shard transactions with shards directly communicating with each other. An atomic locking mechanism is used to ensure the consistency of cross-shard transactions. Content summarized by AI chatbot
