A Universal Blockchain Protocol Enabling Cross-ledger Access through Business Modularization. 

Project stage


Detailed description

OneLedger is a cross-ledger agnostic protocol that enables high-performance scaling using a sharded and modified practical Byzantine Fault Tolerant consensus scheme -- which allows for either a permissionless or permissioned setting. 

By coupling public key infrastructure (PKI) with identity management, nodes (and node operators) will have a defined trust hierarchy that allows them to participate in the consensus of the OneLedger chain or any sidechain. OneLedger sidechains can be synchronized with the current state of other networks (Ethereum, Bitcoin, etc.). 

Any cryptocurrency that supports hashed time lock contracts (HTLC) and payment channels could be deposited into an account or address with the amount credited onto the OneLedger sidechain. This allows for a scalable and transparent solution that is off the main network or chain and is now off-loaded to the OneLedger side-chain. An arbitrary number of transactions between users can occur on a OneLedger side-chain prior to the final user requesting a withdrawal of their balance from the hashed time lock address / account on the main chain to the address / account of their choice. 

Essentially, OneLedger provides a scalable `off-chain` solution from any main chain and offloads the consensus to the corresponding OneLedger side-chain which inherits all of the properties of the OneLedger protocol. 

By using role control with PKI, enterprises can also launch their own permissioned sidechains. Businesses will be able to define the precise role of node operators that participate on their sidechain. In addition, by utilizing OneLedger’s unified framework, companies can develop their distributed ledger technology application with a single codebase and simultaneously launch their product across multiple infrastructure networks of their choosing.


From small business owners to enterprises, OneLedger’s mission is to simplify businesses’ adoption of blockchain technology and its integration into their specific business applications and products. Through OneLedger, both businesses and individuals can leverage the platform to create both public and private blockchains with their own uniquely-identified network consensus. 

With the use of role control, enterprises can also separate read and write access on their permissioned network. Some industries, like healthcare, require people with the appropriate roles to view certain records. In addition, businesses will be able to create and manage their own community-owned digital wallet and credit system.

By leveraging the platform’s provided blockchain-based business tools, modern-day companies can efficiently and effectively adapt their business models to this blockchain technology.


  • Business Modularization: OneLedger forms a realizable and verifiable blockchain network which is modularized from real-world functionality, based on the sharing and immunity mechanisms provided by blockchain techniques. 
  • Protocol-based Blockchain Communication: All transaction data and real source records are written into distributed nodes by validation mechanism of data sharing through OneLedger protocol. OneLedger protocol enables communication and access across the blockchain, and allows for deployment and extendability across various Blockchain networks. 
  • High-performance Transaction: High-performance transactions enabled by a uniquely-engineered role and arbitration mechanism allowing for storage of data in a hierarchical structure.
  • Multi-chain Runtime Support: Focuses on providing a consistent runtime which is compatible with various blockchain protocols and application development stacks

    • Token symbol ? Token symbol — a shorten token name. It is used during an ICO and after the coin listing at the cryptocurrency exchanges. : OLT
    • 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. : 15,000,000 USD
    • Token type ? Token type — a platform for a startup launch that influences the stability of blockchain operation, the speed of transactions and the fees. :Ethereum (ERC20)
    • 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. :4,000,000 USD
    • 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

    • Accepting currencies ? Accepting currencies — cryptocurrencies and fiat currencies that can be used for buying the project tokens. :ETH,
    • 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. :Canada, China, Ethiopia, Iran, Iraq, North Korea, Serbia, South Korea, Syria, Trinidad and Tobago, Tunisia, USA, Vanuatu,
    • 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. :Yes
