The Stacks blockchain allows for increased transaction throughput using a mechanism called microblocks. Bitcoin and Stacks progress in lockstep, and their blocks are confirmed simultaneously. On Stacks, this is referred to as an ‘anchor block’. An entire block of Stacks transactions corresponds to a single Bitcoin transaction. This significantly improves cost/byte ratio for processing Stacks transactions. Because of simultaneous block production, Bitcoin acts as a rate-limiter for creating Stacks blocks, thereby preventing denial-of-service attacks on its peer network.
However, in between Stacks anchor blocks settling on the Bitcoin blockchain, there are also a varying number of microblocks that enable drastically more transactions to be processed. This allows Stacks transaction throughput to scale independently of Bitcoin, while still periodically establishing finality with the Bitcoin chain. The Stacks blockchain adopts a block streaming model whereby each leader can adaptively select and package transactions into their block as they arrive in the mempool. Therefore when an anchor block is confirmed, all of the transactions in the parent microblock stream are packaged and processed. This is an unprecedented method for achieving scalability without creating a totally separate protocol from Bitcoin.
