Gold is a rock. Bitcoin is not a f------ rock.

Bitcoin has proven itself as a store of value protocol. Stacks is on a mission to prove that Bitcoin can also be the bedrock of the user owned internet. Stacks brings scalable transactions and expressive smart contracts to Bitcoin, putting Bitcoin’s $1T capital to work.

.BTC domains are registered through a smart contract on Stacks, secured by Bitcoin. This smart contract implements a decentralized name registry written in Clarity lang. Ownership of every .BTC name is represented in a hash of the Bitcoin blockchain. Instead of spamming the bitcoin blockchain with name registrations, thousands of Stacks transactions settle in a single transaction on the bitcoin blockchain.
