Most Blockchains cannot talk to each other.

They have to use a bridge....

Even EVM chains...

XCM...

Also known as, 

Cross-Consensus Message Format, 

Makes it possible for Blockchains created on @Polkadot to talk to each other. 

By talking to each other, I mean, send messages/tokens/transactions between themselves without using bridges.

On your left, you can see Polkadot, also known as the relaychain

By your right, you can see Polkadot-based blockchains. 

You can see that the relay chain is in direct communication with other blockchains. 

That means I can send $PEAQ from the @peaq blockchain to the relaychain without using a bridge.

The same way I can send $DOT from the relaychain to Bifrost.

Here's what is happening in the image below:
