Blocknet is a cross-chain protocol for inter-chain transactions and a decentralized exchange. It is primarily focused on connecting blockchain networks, but is also developing a decentralized exchange to enable trade digital assets across separate blockchains. It is meant to connect the growing number of blockchain projects and make them inter-operable. Blocknet uses a Proof-of-Stake (PoS) consensus mechanism that has three different types of nodes to verify transactions. The network is powered by the BLOCK coin.

OAX is developing a decentralized exchange that will address some of the privacy and security risks of centralized exchanges. Their platform will have a shared and decentralized order book, and will include the following features: a mechanism for credit risk assessment, structured dispute resolution, and a collateralized deposit system. OAX will apply the 0x protocol to improve liquidity for assets on the platform. Orders will be broadcasted publicly, and will be viewed by all potential takers. ddecentralized exchange model

The DODO exchange allows users to trade Crypto through a liquidity protocol that is powered by their Proactive Market Maker (PMM) algorithm. It is an oracle-aided algorithm with an advanced pricing formula that provides contract-fillable liquidity, designed to maximize efficiency and reduced price slippage compared to decentralized exchanges that use an automated market maker (AMM) model. Another relative advantage of the DODO exchange is that it give liquidity providers greater flexibility.
