When a player purchases an in-game item using Bitcoin Lightning, a QR code of the payment request will be generated in accordance with BOLT-11. BOLT-11 is the account protocol for the Lightning Network (request for payment). Further, this invoice, account and elements of the monitoring system, similar to the monitoring of events in the EVM (Ethereum Virtual Machine), which listens to the Blockade Games node, to obtain the status of the invoice.

* There are other ways to control this, for example, through BTC Relay.

After the player scans the QR code with their Lightning-compatible wallet, the Blockade Games node will use the payment details (if successful) to mark the invoice as paid. Once this invoice has been paid, the Blockade Games monitoring system listening on the node for this invoice will be able to process the payment accordingly.

This information can also be used for a smart contract on the Ethereum Mainnet - however, if there is busy traffic and high gas prices on the network at the time, it can be a slow and costly process. To get around this, Blockade Games studio has the opportunity to mint digital assets directly into the user's game wallet, avoiding the main network. Game contracts are hosted simultaneously in the Ethereum core network, as well as in the high-performance side chain of Blockade Games of the second level. Depending on the preferences of the buyer, their purchase can instantly make changes to the elements of the game chain directly for the user, providing instant in-game access to the user's game assets.
