CryptoBridge is a decentralized exchange (DEX) powered by the BridgeCoin (BOC). BOC holders receive 50% of the profits that CryptoBridge collects from trading fees and become innvestors in the BridgeCoin exchange. In order to receive their share of the profits, users must stake part of their BOC holdings for a period of 1, 3, 6 or 12 months. The longer you stake your coins, the higher the staking bonus will be.
CryptoBridge is built on the Bitshares blockchain, which has relatively fast confirmation times.

Trading Fee: 0.2 %

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.

Ren, previously known as the Republic Protocol, is a decentralized dark pool exchange protocol; designed to support large volume trades, without effecting the prices of the assets being traded. The blockchain-based, dark pool protocol has built in privacy mechanisms and is provably fair. It uses secure multi-party computation (sMPC), and a network of Darknodes, to match orders without exposing their volume or price. Their private order book will also enable cross-chain trades of tokenized assets. The Singapore based company is also developing RenX, a decentralized dark pool exchange, built with the Republic Protocol. REN is the network's utility token. It provides security to the network, and is staked to enable the operation of a Darknode in the network.
