This is an open source blockchain, with its blockchain released, fast confirmations theoretically in a second at best. All contracts and layers that are released in Etherium are compatible with this chain.
What I like most about this cryptocurrency is that it is easy to manage a wallet, only using Metamask their respective configurations will already have one available. In fact writing this review I used the blockchain of this asset and I used its faucet and it was really interesting and really fast.
In general this is another chain with participation protocol for the verification of blocks and the use is very similar to eth.
