The Nervos Network is an open-source public blockchain ecosystem that is designed to secure multiple assets. Unlike other smart contract platforms that require users to pay transaction fees to help secure the underlying networks, the Nervos Network hopes to create an incentive system that will enable multiple assets to be secured regardless of their price volatility. It does this by capturing the total network value through its native coin the Nervos CKByte, which entitles holders to storage rights on the Nervos blockchain. The network uses a PoW consensus mechanism.

The Kava token fuels the Kava.io cross-chain collateralized debt platform. Kava’s multi collateral CDP system allows users to collateralize a variety of assets so that they can increase their exposure to favorable trading conditions in volatile markets. The Kava platform is secured by over 100 validators and uses the Tendermint consensus algorithm.

AION calls itself a 3rd generation blockchain network, and is primarily focused on connecting blockchain networks. AOIN aims to solve the interoperability issues facing the various blockchains, and be the connecting bridge between them. AION's cross-chain platform has different consensus mechanisms for interchain and on-chain transactions. The on-chain consensus mechanism combines BFT (Byzantine Fault Tolerance), dPoS (Delegated Proof-of-Stake) and a new neural network inspired verification algorithm known as Proof-of-Intelligence.
Interchain transactions are managed by bridges. The bridges has a consensus mechanism that is different from the main AION chain, and each bridge is secured by an individual consensus. The bridge validators will be rewarded by interchain transaction fees.
