Like the Lightning Network, it functions as a layer on top of Bitcoin. STX aims to protect user privacy, maintain internet security, and lessen data breaches. The STX token, the native coin of the Stacks blockchain, is used for transaction processing and smart contract execution.
Stacks uses the Clarity programming language, which improves smart contract security and transparency. The protocol uses micro blocks for independent validation. Also, it ensures security using the Bitcoin blockchain. Through token-locking mechanisms, STX tokenomics are intimately associated with Bitcoin. These mechanisms facilitate network consensus and security and reward participants with Bitcoin
Since its inception, significant advancements have been made to Stacks. For instance, the Nakamoto release aims to strengthen the network’s connection with Bitcoin. This connection will allow Stacks users to write directly to the blockchain.
