Hello, my name is Claudiu, i represent 01node, we are a trusted validator on some POS networks like Cosmos, Near, Skale, Solana, Terra, etc.
We run only on bare metals servers colocated in a DC in Romania.
We have a 13.9% commision right now [for indexing and query] and hopefully it will stay this way for a long time.
