      Fairground features

      Fast network, optimised for trading

      Vega’s purpose built blockchain has sub-second block times and is optimised for fully decentralised trading. It’s built on top of the mature Tendermint consensus library, and everything from the mempool to the fee model and proof-of-stake implementation are optimised to make Vega as safe, fair, and high performance as possible.

      Next generation liquidity mining

      Vega’s advanced incentivisation system directs liquidity to the markets that need it most. Trading fees are determined by competitive bidding for each market, ensuring the best price is achieved for both traders and liquidity providers. Early supporters of markets earn a larger share of the fees that are distributed through Vega’s unique liquidity provision share mechanism.

      Capital efficient permissionless derivatives

      Liquidations and risk management are atomic and margin calculations use sophisticated risk models that allow Vega to maintain safety with margin requirements and leverage that are competitive with centralised alternatives. The protocol is designed as a toolbox of optimised components that allow the community to permissionlessly propose and create markets for almost anything.

      Native cross-chain support, starting with Ethereum

      Vega is designed from the ground up to integrate with Ethereum and other emerging DeFi ecosystems, rather than compete with them. All assets traded on Vega originate on other chains, and the bridge protocol makes deposits and withdrawals as easy as for native dapps. Integration with more chains and richer composability will be added over the coming months.

      Rich, developer friendly APIs

      Vega is built on a set of advanced financial and trading primitives, with a technical architecture that allows for near infinite flexibility for building financial applications. Vega nodes expose rich data about governance, markets, orders, trades, prices, margins, positions, and much more. Data is accessible via easy to use and comprehensive gRPC, GraphQL, and REST APIs.
