# daVinci Marketplace & Harmony Protocol

The [daVinci marketplace](https://davinci.gallery/) is a NFT marketplace that supports the creation, buying and selling of NFTs (Non - fungible tokens) minted on [Harmony](http://harmony) blockchain. That means [ONE](https://www.coingecko.com/en/coins/harmony), the Harmony native token, fuels all transactions on daVinci´s platform, in contrast to Rarible or OpenSea that use ETH.

### **Benefits of Harmony ONE vs. ETH based platforms.**

* NFTs minted on Harmony ***cost less than 0.01$ - 0.001ONE*** *,* with [EPoS](https://medium.com/harmony-one/introducing-harmonys-effective-proof-of-stake-epos-2d39b4b8d58#:~:text=The%20effective%20stake%20of%20a,by%20the%20validator's%20effective%20stake.) (Effective Proof-of-Stake) consensus algorithm, **requiring 99% less energy use than PoW**. Ethereum case is the opposite, 50-100$ approx. for a transaction with PoW (Proof-of-Work) consensus algorithm, which required a lot of computational power. **Climate activists have RED FLAGGED ETH 🚩**, specifically, in order to power the data centers that sustain the blockchain they are spending a lot of energy. In daVinci, the entrance barrier for newcomers is much lower, giving every single person the NFTs creation possibility, and we can call it **“Green”** ♻️ for the environment.
* On the Harmony blockchain each block is signed each [2 sec. time](https://medium.com/harmony-one/2-seconds-block-time-on-harmony-mainnet-aba78ee5643f), so the transaction in daVinci´s platform as a user experience is like using a VISA.
* Comparison between Harmony and other crypto blockchains.
