The Lightning Address is an Internet Identifier that allows anyone to send you Bitcoin over the Lightning Network without the need to request invoices every time. The Lightning Address empowers everyone to send money like we send emails — instantly and abundantly. This is coupled with Lightning Networks ability to send bitcoin instantly and with minimal fees.

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.
