Oasis Labs is rethinking blockchain for the real world.

Project stage


Detailed description

Ekiden enforces a strong set of security and availability properties. By maintaining on-chain state, it achieves consistency, meaning a single authoritative sequence of state transitions, and availability, meaning contracts can survive the failure of compute nodes. Ekiden is anchored in a formal security model expressed as an ideal functionality. We prove the security of the corresponding implemented protocol in the UC framework.

The implementation of Ekiden supports contract development in Rust and the Ethereum Virtual Machine (EVM). We present experiments for applications including machine learning models, poker, and cryptocurrency tokens. Ekiden is designed to support multiple underlying blockchains. We have built one end-to-end instantiation of our system, Ekiden-BT, with a blockchain extending from Tendermint. Ekiden-BT achieves example performance of 600x more throughput and 400x less latency at 1000x less cost than on the Ethereum mainnet. When used with Ethereum as the backing blockchain, Ekiden still costs less than on-chain execution and supports contract confidentiality.


Smart contracts are applications that execute on blockchains. Today they manage billions of dollars in value and motivate visionary plans for pervasive blockchain deployment. While smart contracts inherit the availability and other security assurances of blockchains, however, they are impeded by blockchains’ lack of confidentiality and poor performance.


Ekiden is a system that addresses these critical gaps by combining blockchains with Trusted Execution Environments (TEEs), such as Intel SGX. Capable of operating on any desired blockchain, Ekiden permits concurrent, off-chain execution of smart contracts within TEE-backed compute nodes, yielding high performance, low cost, and confidentiality for sensitive data.


Next-generation blockchain platform for scalable, privacy-preserving smart contracts:

  • High performance to support diverse applications, from games to machine learning
  • Security and privacy for data and computations
  • Flexible and easy to use, with built-in machine learning and data analytics

    • Token symbol ? Token symbol — a shorten token name. It is used during an ICO and after the coin listing at the cryptocurrency exchanges. : OASIS
    • 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. :NA
    • Total supply ? Total supply — a total amount of tokens that will be released by the developers. :NA
    • 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. :NA
    • 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 Open
    • 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. :BNB,
    • 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
