Abstract

Blockchain is a system where connected nodes work together to perform various activities within the system, and all of them maintain their own copy of a system ledger that stores transactions. With the emergence of new blockchain networks and the massive growth of users on the network the need for inter blockchain communication is now at an all-time high. At first glance the two existing bridging protocols, the Poly Network and the Inter Blockchain Communication (IBC) protocol, seem to be completely different, but a closer inspection reveals a connection between them that will most likely be seen in future blockchain bridges as well. This paper discusses their similarities and differences and ends by making a prediction about future blockchain bridges.

Keywords: Blockchain, Blockchain network, Bridges, Poly Network, Inter Blockchain Communication
