In fact he cites a company called Blockade Games, linked to the world of games on Blockchain, which uses the combined Bitcoin light network on the ethereum blockchain.
That is, there is an interaction of a contract in Ethereum, to then receive payment in Bitcoin using the Light Network.
This is because, according to the company, people in the future will increasingly be using the blockchain, and will want to hold bitcoins.
With this union there is the possibility of having more advantages, namely:
- Creation and use of a smart contract;
- Greater scalability;
- Value conversion between two blockchains.
The Blockade Games company uses a system where the user queries the Light Network channel by scanning a bar code, interacting with the network.
At this point another channel opens linking the Light Network channel, and the ethereum channel to exchange the contract.
Everything is started using the portal made available to the gaming company.
An interesting article on Medium explains exactly the function that this solution has.
Obviously this represents a beginning but one thinks for example, using a blockchain that connects to the chain of multiple blockchains simultaneously.
