DEx.top now supports Bitcoin Cash (BCH), with plans to add support for more cross-chain trading pairs such as BTC and EOS in the future.
Jointly developed by DEx.top and iBitcome, the Open Federated Gateway Protocol (OFGP) is a fully open source protocol that enables cross-chain transactions.
Open refers to the protocol being open-source: any individual can develop their own gateway.
Federated refers to the nature of the Braft consensus algorithm used in OFGP. In a network with 3f+1 nodes, specified addresses that manage token escrow and sidechain issuance are multisig addresses that require the approval (i.e.: signature) of >2/3 of the nodes before undertaking certain actions.
Gateway refers to the protocol enabling assets to be transferred across blockchains.
A fuller technical explanation of OFGP may be found in the whitepaper.
The lack of cross-chain trading pairs on decentralized exchanges is one of their most critical disadvantages when compared to centralized exchanges. OFGP tackles this weak link by enabling fully transparent escrows, allowing DEx.top to theoretically support any asset from any blockchain. Each gateway developed using OFGP is maintained by three roles: signers, watchers and key store services.
The transaction below illustrates the responsibilities of each role:
As with any escrow mechanism, security measures are often a user’s top concern. OFGP employs multiple layers of security to ensure the safety of users’ assets: firstly, all escrow addresses and contracts require signatures from multiple nodes to move their funds, preventing any single node from stealing any assets held in escrow. Key store services also provide an additional layer of security.
Furthermore, OFGP is an open source protocol that anybody can use to create their own gateway. Users are free to “vote with their feet” and use their preferred gateway for cross-chain transactions, incentivizing honest behavior and faster, lower-cost services.
DEx.top will be using an implementation of OFGP named Mallow, which is supported by several notable partners including leading mining pools BTC.COM and Antpool. Named for a protagonist from Isaac Asimov’s Foundation series, Mallow is also the first gateway to be developed using the Open Federated Gateway Protocol.
With Mallow, DEx.top is the first decentralized exchange to successfully support cross-chain liquidity. BCH will be the first asset supported in the form of WBCH (“wrapped” BCH), an ERC20 token that enables seamless value transfer between Bitcoin Cash and the Ethereum network. Mallow is also fully extensible to other blockchain protocols such as EOS and BTC.
Already, several EOS sidechain developers are building DApps using OFGP that will also be accessible to BTC and BCH users.
Interoperability is a major focus area for blockchain research today. To unlock the next wave of blockchain’s potential applications, or perhaps even the next killer DApp, cracking the cross-chain puzzle is an absolute necessity.
DEx.top is establishing itself as a technical leader by pioneering initiatives such as OFGP, partnering with wallets and DApp browsers such as iBitcome and Trust Wallet and more, in the pursuit of a robust and interconnected decentralized ecosystem.
DEx.top is a leading Ethereum-based decentralized exchange that utilizes the ROC (Replayed On Chain) trading mechanism, supporting off-chain orderbooks and on-chain settlement to ensure asset security and enable instant trading. DEx.top is committed to provide the most secure, efficient, and low-cost decentralized trading environment to customers of all levels.
