This entire implementation allows Harmony to run a highly concurrent protocol. They also adopt Kademlia routing which is able to achieve these cross-shard transactions which can scale logarithmically with the number of shards in the network. Not only does Harmony shard its network nodes, it also shards blockchain states, which allows for linear scaling in all three aspects of storage, transactions, and machines.
#ONE COIN HARMONY CODE#
As stated in their whitepaper, Harmony uses RaptorQ fountain code which allows the network to propagate blocks quickly or within shards. Harmony is implementing networking techniques that can improve the speed of message propagation and achieve consensus faster. This means that there is no single bottleneck to the confirmations for all of the transactions.Įssentially, with the Harmony approach, connection latency is greatly reduced and the transaction throughput can scale as the network grows. This allows the network to process numerous different transactions in parallel. The Harmony consensus protocol, which they call Effective Proof of Stake, uses the latest design principles such as sharding and pipelining. Network Communication in a round of Consensus. However, PoS has its own unique challenges. Indeed the Ethereum protocol is trying to move to their Casper PoS consensus to address their scalability issues. Other protocols such as Proof-of-Stake use different incentive mechanisms that overcome some of these challenges. Currently, blockchains such as Bitcoin's, use Proof-of-Work consensus protocols which have become inherently expensive and slow. Consensus Protocolīlockchains are goverened by consensus and the type of protocol used can drastically impact on the speed with which decentralised consensus is achieved. These include dApps such as decentralised exchanges, high-throughput payment systems and Internet-of-Things transactions.
They have built in a number of important innovations into their Consensus Protocol, internal systems and network engineering.īy implementing these innovations, Harmony will provide a platform for Decentralised Applications (dApps) which were not feasible on other blockchains. In order to achieve the goals of scalability the Harmony built the entire technology stack from the ground up with a focus on optimisation.
It’s been a busy year at Harmony, so let’s dig in and explore some of the details of the progress being made. The project has also been able to migrate from the ERC-20 and BEP-2 tokens originally issued to its own native tokens.įinally, the project has implemented a staking system based on Effective Proof of Stake (EPoS). This incentivizes users and could be used for credit ratings, ad exchanges, and other data sharing that’s traditionally seen centralized platforms profiting and users being left with nothing.Īfter launching its mainnet in June 2019 Harmony has seen excellent growth, and as of June 2020 there are more than 1,000 nodes helping to decentralize the network. Harmony also uses its zero-knowledge proofs to enable data sharing with consumer privacy. In practice, Harmony helps businesses to build marketplaces for fungible token usage (such as loyalty points or energy credits) and non-fungible assets (such as in-game digital assets). Harmony also implements optimal cross-shard routing and fast block propagation. The technical focus of the project is on resharding and secure staking with decentralized randomness. They plan to address the issues faced in other blockchain ecosystems through the use of the best research and engineering practices in an optimally tuned system. Harmony provides a high-throughput, low-latency and low-fee consensus platform designed to power the decentralized economy of the future. I will also analyse the long term adoption potential of their ONE token. I will dig into their technology, team and development. In this Harmony review I will give you everything you need to know to make that decision. This after completing a large private seed sale back in May of 2018. They are also the latest project to be raising funds on the Binance Launchpad. Using a "full-stack" approach, Harmony is developing a sharding based blockchain that is not only scalable but provably secure, and energy efficient. They have built their platform from the ground up with optimisation in mind. Harmony (ONE) is one of the latest projects that is trying to tackle the issue of blockchain scalability.
