Ark is a decentralized company developing a next level blockchain, with the main scope to create the possibility to have different blockchains communicating between them. The technology is called 'SmartBridge"​. Also, right now, the focus is on "Vendor Field"​ a 64 bytes custom available space on Ark blockchain for each transaction. This Vendor Field feature can be used for just checking the data scenarios, instead of querying the blockchain.
