GreenChair Makes Digital Collectibles Fun

GreenChair's digital collectibles (NFTs) are made using the Polygon blockchain, a carbon neutral layer 2 blockchain.

A polygon Transaction uses a fraction of the energy used by an LED lightbulb. Below are the Watt Hours that a Polygon transaction and an LED lightbulb consumes.

Polygon Relies on Ethereum for it's security layer.

While Polygon transactions use a very small amount of electricity, it does rely on Ethereum for it's security layer. Now that Ethereum is a Proof of Stake blockchain, it uses 99% less energy than it did when it was a Proof of Work blockchain.

Unfortunately, the exact energy usage of a Polygon transaction, including it's interaction with Ethereum is not currently available. The unknown element is just how many Polygon transactions are bundled into a single Ethereum TransactionWith that said, the energy usage of a single Ethereum transaction is known to be 40Wh.^3. A single Polygon transaction would use a fraction of that energy. The exact amount of energy is unknown to the GreenChair research team at the time of writing.
