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.

Mixin is a cross-chain payment network for digital assets. Mixin provides a cross-chain solution with built-in smart contracts that facilitates crypto-asset transfers. Developers can also build cross-chain DApps based on Mixin Network protocol.
Mixin also has a messenger that is built on top of their platform and allows users to access their crypto-assets with a phone number and a 6-digit PIN code. Mixin supports Bitcoin, Bitcoin Cash, Litecoin, Ethereum, Ethereum Classic, Ripple, Sia, and plans on adding more.
The network is powered by the XIN token.

MOAC is developing a multi-layer blockchain platform that aims to improve transaction speeds and scalability. MOAC's architecture is divided into a main chain and microchains, and uses sharding to improve network performance. This enables an asynchronous smart contract platform that increases the number of contracts that can be processed, as well as transaction speed.
MOAC's development platform allows DApp creators to choose from a variety of consensus algorithms. It also enables cross-chain exchanges of value between different blockchains.
