• XCM works throughout chains, good contracts and non-fungible tokens (NFTs).
• It additionally helps communication between networks with totally different consensus mechanisms, like between Bitcoin and Polkadot.
• Polkadot founder Gavin Wooden introduced XCM v3 had lastly merged on Tuesday, 17 January 2023.

Polkadot, the scalable heterogeneous blockchain ecosystem, is at the moment one of many crypto trade’s most strong networks, and has a brand new characteristic besides.

In keeping with Polkadot founder Gavin Wooden, the interoperability blockchain’s “cross-consensus message” formar (XCM) model 3 is lastly deployed. Wooden, who additionally based Kusama, Ethereum and Parity Applied sciences, introduced on Tuesday that XCM v3 had been in improvement for fifteen months.

After precisely 15 months in improvement, @polkadot XCM model 3 is merged. This permits bridges, cross-chain locking, exchanges, NFTs, conditionals, context-tracking and extra. https://t.co/dqcLXOmDa9

How does XCM work?

XCM began with cross-chain communication between totally different chains at its core, earlier than the shift to cross-consensus message – the purpose of which is to avail a language by which totally different consensus methods can talk.

The XCM design gives directions on compose, ship, and interpret messages throughout chains. The vacation spot chain is the one which executes the directions, with help for programmable, trustless and wealthy knowledge.

Mainly, XCM is customary by which protocol builders can outline knowledge and origins that their explicit chains can ship to or obtain from. As an example, a developer can leverage XCM to permit for communication between Bitcoin (a proof-of-work community) and Polkadot (a proof-of-stake community).

However XCM v3 deployment does extra than simply to allow cross-consensus communication between chains. It could possibly work throughout good contracts, bridges, pallets, exchanges, and non-fungible tokens (NFTs).

An instance is the place message format permits interoperability between parachains, eradicating the necessity to use bridges.
