Open Consensus for 10B People.

Project stage

Only a whitepaper

Detailed description

Harmony builds an open marketplace at Google-scale for the decentralized economy. This project aims to provide a consensus protocol over the open Internet at 10 million transactions per second with 100-millisecond latency and at most 0.1% fee. Harmony’s goal is to be 1,000+ times faster and cheaper than Bitcoin and Ethereum. We are rebuilding the decentralized economy with 10x innovations in all components: transport network (Google’s UDP, Bloom tables, 5G mobile), consensus protocol (Byzantine committees, acyclic graphs, monopolist fees), and system tooling (unikernels, multi-core in Rust, zero-copy streaming).

Harmony plans to integrate the following aspects of a consensus protocol

  • Scripts and contracts: Covenants, Ethereum
  • Fairness and efficiency: anti-pooling , proof of useful work , proof of stake
  • Security and privacy: multi-signatures , attack models , verification
  • Off-chain and edge clients: Lightning , IoT


Most protocols share similar techniques but different terminologies for scaling. It is critical to specify the metrics and the complexity of different implementations.


Computers automate tasks, Internet delivers information, smartphones bring mobility at almost no cost. Harmony will bring the next revolution of the decentralized economy to the masses, in which enforcing transactions and contracts is essentially free.

  • Token details

    • Token symbol ? Token symbol — a shorten token name. It is used during an ICO and after the coin listing at the cryptocurrency exchanges. : HARMONY
    • Fundrasing target ? Fundraising target — the maximum amount of funds to be raised during an ICO. When it is reached, the developers stop selling the tokens because they do not need to raise more money for the project development. : NA
    • Token type ? Token type — a platform for a startup launch that influences the stability of blockchain operation, the speed of transactions and the fees. :Own blockchain ()
    • Soft cap ? Soft cap — the minimum amount of funds to be raised for the project development. Sometimes when the soft cap has not been reached, the money is returned to the participants. : NA
    • Role of token ? Role of Token — type of token depending on the opportunities it offers to its owner. Utility tokens give their owners a right to use the project services, security tokens are aimed at bringing profit, and currency tokens are a money substitute. :Utility token
    • Total supply ? Total supply — a total amount of tokens that will be released by the developers. :21,000,000,000 HARMONY
    • Escrow agent ? Escrow agent — a qualified agent who has the right of signature in a multisig wallet. An escrow agent participates in an ICO, monitors the financial operations of the developers and confirms their fairness. :No
    • Tokens for sale ? Tokens for sale — the number of tokens offered to the participants of an ICO. :4,200,000,000 HARMONY
    • Whitelist ? Whitelist — a list of participants, who get an opportunity to buy tokens. To be whitelisted, you need to register on time because the number of participants and the registration period are usually limited. :Whitelist Soon(Start TBA)
    • Additional emission ? Additional emission — an additional release of tokens. It can be done once after the crowd sale or on an ongoing basis. In the projects with a limited emission there is no additional emission. :No
    • Exchange listing ? Exchange listing — an assumed date when the token will be listed at a cryptocurrency exchange. The developers usually indicate it in a roadmap and a white paper. :NA
    • Accepting currencies ? Accepting currencies — cryptocurrencies and fiat currencies that can be used for buying the project tokens. :NA
    • Can't participate ? Can't participate — the countries where it is prohibited to buy tokens. These can be countries where ICOs are prohibited altogether, or countries that have the requirements that a particular project does not meet. :No
    • Know Your Customer (KYC) ? Know Your Customer — a verification procedure for ICO participants, during which the developers can ask for personal data, a photo and a scanned copy of a passport of a potential investor. :No
