6. NFT and blockchain

Blockchain used in capture.x

Capture.x currently uses Polygon as the blockchain for storing NFTs.

In recent years, Bitcoin, Ethereum and other major crypto assets (virtual currencies) have been considered environmentally harmful because they are based on mining, known as Proof of Work (PoW). The main reason for this is that mining is a computational race, where the miner who wins the calculation gets the coins issued each time. The biggest problem is the content of the calculations. In virtual currencies like bitcoin and ethereum (before the hard fork to the Merge), the calculations that miners do are completely meaningless. Just for the sake of competition, they impose an irreversible formula with a high load on computers (CPUs, GPUs). Due to the high load, the power consumption is very high, resulting in a high environmental impact.

Since capture.x is an application to accelerate the realization of carbon neutrality, the primary selection of the blockchain to store NFTs is whether it is good from an environmental perspective. The technical specifications will be chosen based on the second evaluation. As a result, the blockchain currently adopted is Polygon. It is one of the most efficient blockchains in terms of power consumption to maintain mining, and is likely to maintain the most reasonable level of gas costs (transmission fees) in sending and receiving NFTs between digital owners.

As for the blockchain, we plan to use the most appropriate one from both an environmental and technical perspective from time to time worldwide, and it may be multi-chain compliant (using multiple blockchains). We are also working on the development of our own capture.x chain and are looking to adopt our own chain.
