Blockchains are the technology on which NFTs (non-fungible tokens) are minted. Their innate ability to store transaction and ownership information is the very thing that gives these digital collectibles life and enables the desire that we have to collect them. Sweet uses.
Among the blockchains that Sweet uses to mint NFTs is Polygon. Designed as a second layer to Ethereum, it allows more efficient minting of NFTs and is much less environmentally taxing.
Polygon is a blockchain technology running on the Ethereum network. It was created due to scalability issues on Ethereum. As a second-tier, layer on top of Ethereum it allows faster transactions at a lower cost than the main Ethereum blockchain, while maintaining the same high level of security as Ethereum.
While enjoying these benefits of faster transactions and high security, Polygon adds two more benefits--lower gas fees for minting and a greener carbon footprint. Polygon has the benefit of reducing the carbon impact of NFTs via its use of a Proof-of-Stake (PoS) network.
In comparison to other blockchains, Polygon consumes just 0.00079 terawatts (TWh) of electricity per year. To put that in perspective, one transaction on Polygon is the equivalent of watching a 30-60 second video on Youtube. The Polygon tokens standard is called ERC-721.
