Obscuro. Unlocking a whole new world of use-cases with privacy on Ethereum

Obscuro is a layer 2 solution for Ethereum that brings privacy and scale. It ensures the inputs, contract state and execution are always encrypted. No changes to dApps, just migrate and gain privacy.

Scaling Ethereum
Obscuro, as a Layer 2, massively scales Ethereum with faster, cheaper transactions, while inheriting all its security and ecosystem.
Privacy
Transact with full privacy on any Ethereum smart contracts. Obscuro provides the entire EVM - every Ethereum application can become a private Obscuro application with no changes.
Developer experience
Obscuro has solved the privacy developer experience. Application developers do not require any specialist knowledge, you can simply port over your Ethereum application. You can continue to use all the great existing Ethereum tooling like Remix, Ganache and Ethers.js.
User experience
There is no change to the end user experience. No need to generate complex ZKPs or change the way you interact with Ethereum applications today. The Ethereum to Obscuro user experience is seamless.
Maximal Extractable Value
Blockchains rely on miners seeing transactions in order to be able to validate them and secure the network. This creates a front-running issue, known as Maximal Extractable Value (MEV) that acts a tax on transactions. On Obscuro, there can be no MEV.
POBI
With the novel Proof of Block Inclusion (POBI) protocol, assets can be withdrawn back into Ethereum much faster than competing Layer 2s. In addition, the Obscuro network is decentralized from day one. Run by its users, Obscuro is unstoppable, uncensorable and will never go down.

developers


existing

The design of Obscuro allows developers building with the EVM to port over existing Dapps without any changes. By deploying your existing EVM-based solution to Obscuro, straight out of the box, you get:

  • complete transactional privacy
  • privacy over all the computation and data
  • private events
  • an encrypted version of your Dapp
  • The only public element will be your getters which can be made private with one line of code.

    new

    Build new game-changing Dapps that leverage privacy as a new primative. With full programmable privacy, you can create fairer DeFi contracts, games with hidden maps, unlock real world assets, all while leveraging Solidity and other EVM supported languages and tooling.

    testnet

    The Obscuro testnet is now live. If you're a developer you can get started immediately using all the existing EVM tooling. If you're a user you can start testing Dapps. You'll need to request test OBX from the Discord Faucet.

    use cases

    Gaming
    Computational privacy enables developers to bring more game mechanics on-chain, such as player positions and hidden maps to unlock “fog of war” type games and prevent players from front-running.
    Private DeFi
    Programmable privacy enables developers to pick and choose the parts of a DeFi Dapp to make private. It might make sense to keep liquidation levels private on lending protocols to prevent "liquidation hunting"
    dark pool trading
    A dark pool is a privately organized exchange for trading securities where exposure can be hidden until after execution and reporting. This allows investors to trade without publicly revealing their intentions during the search for a buyer or seller.
    Sealed auctions
    In a sealed bid auction, bidders privately submit their one best offer in a sealed envelope. The bids are opened privately by the auctioneer and seller.
    Private agreements
    Agreements, such as a Service Level Agreement (SLA) between a supplier and buyer, are incredibly sensitive. They reveal commercial relationships and impact reputation where an SLA has failed. Agreements deployed to Obscuro can be entirely private, such that aside from the participants, nobody even knows the contract exists.
    Identity
    Solving KYC on blockchain is one of the biggest challenges. Obscuro allows you to build KYC solutions with complete privacy enabling users to only reveal the bits they choose to disclose on demand.

    Encrypted by default
    On the left is Obscuro. All transaction details are fully encrypted by default. No state leaves the enclave in an unencrypted state unless the developer has programmed the Dapp to do so. On the right is a standard block explorer with everything out in the open

    whitepaper

    Obscuro is a decentralized Layer 2 privacy solution built on top of Ethereum. Obscuro is designed to enable any Ethereum contract to operate at a larger scale, lower gas, without risk of MEV and crucially, with full privacy. It leverages a technology called Trusted Execution Environments, it's the technology that secures most of your devices. TEEs provide complete privacy, even from the operators of the host machines.
