Potion seller is a game that is located on a blockchain chain that belongs to the BINANCE network. And just like various games in the current industry like Cryptocars metaverse and Cryptoplane, Potion seller also uses BigChainBD technology.&#x20;

BigchainDB combines the properties of a blockchain and a database. It uses Tendermint for all networks and consensus. Each node has its own local MongoDB database, and all communication between nodes is done using Tendermint protocols. These characteristics allow the implementation of large-scale applications in various types of industries, with NFT games being the pioneers.&#x20;

Reasons to use Bigchain DB:

* Our players save money. All player transactions are done without blockchain transaction fees (Gas fee).
* High performance. Save time for players as all transactions can be made immediately without unnecessary waiting.
* Transparent and safe. Transactions made in the game are transparent, ensuring the confidentiality of player data.
