Decred Releases Proposal for Decentralized Exchange (“DEX”) with Eye toward Disrupting Billion-Dollar Exchange Market

junho 5, 2018

Privacy, security, fewer barriers to entry and absence of unnecessary fees among the benefits of next phase of blockchain evolution

[Chicago, IL June 5, 2018] Decred (DCR), an autonomous digital currency with built-in governance, today released a formal proposal for a new kind of decentralized exchange. Known by its temporary working name “DEX,” the proposal suggests replacing the billion-dollar centralized cryptocurrency exchange market with a trustless peer-to-peer model. The proposal comes at a time when the blockchain market seeks new levels of efficiency and questions the privacy, security, fees, and other barriers of the existing system.

“DEX is a topic that has been discussed for some time,” said Jake Yocom-Piatt, Decred Project Lead and one of the authors of the proposal. “Our goal is to structure the conversation so the developer community can step up with real-world solutions. We believe that this call-to-action is long overdue. Blockchain can only move forward by putting more power in the hands of the community. Decentralization has been our guiding principle at Decred and it is what motivated us to create this project, which can benefit the entire ecosystem.”

Key features of DEX

  • It is architected as a simple client and server, without a corresponding token or a blockchain.
  • Server operators never take custody of client funds.
  • It uses on-chain transactions for order fulfillment and rule enforcement.
  • Server operators collect no fee for matching orders.
  • Order matching occurs pseudo-randomly within epochs.
  • Orders placed on the exchange can be internally regulated via rules enforced by the clients and the server.
  • Malicious clients are managed using a reputation system based on Politeia, Decred’s proposal system.
  • Near-instant exchange for smaller orders can be achieved through a related off-chain LN-based network which uses atomic swaps.
  • Servers can connect via a mesh network to allow cross-server order matching.
  • External services, e.g. wallets, can access a simple client API on the server that provides a data feed, ability to place orders, and other services.

Decred’s proposal leverages on-chain atomic swaps, announced in September 2017, making it the first project to support direct exchanges between users of Decred, Bitcoin and Litecoin.
