What is Stacking?
Support the network
Stacking is a critical part of the Stacks network. It helps Stacks reach consensus, stay secure, and process transactions. Stacking is part of the Proof of Transfer consensus mechanism.
Earn Bitcoin
When you stack, you can earn Bitcoin every cycle of 2,100 Bitcoin blocks. How much you’ll earn can vary from cycle to cycle. You can see how much stackers are earning on stacking.club.
Easy to get started
You don’t have to run a node or validate transactions to stack — all you need to do is lock your STX in your wallet temporarily. You can stack by yourself or in a pool with others if you don't meet the minimum.
Start Stacking
There are two ways to stack: by yourself or in a pool. To stack by yourself you’ll need to meet the dynamic minimum, which can change from cycle to cycle. If you don’t meet the minimum, you can still stack by pooling with others. Read the stacking guide to choose a strategy that's right for you.
Stack by yourself
You can interact with the smart contract directly if you meet the minimum amount of STX required for at least one full reward slot.
Stack in a pool
Even if you don't meet the minimum, you can still stack and earn Bitcoin by pooling with others. A service will pool STX together and distribute rewards back to the participants.

How Stacking works
Reward cycles
Bitcoin is paid out in cycles of 2,100 Bitcoin blocks. During a cycle, all eligible stackers are expected to receive Bitcoin from miners. A cycle typically lasts for about 15 days, but can be shorter or longer depending on the Bitcoin block time.
Prepare phase
Every reward cycle is preceded by a prepare phase of 100 Bitcoin blocks. This is when miners gather the Bitcoin addresses eligible for rewards in the coming cycle. To participate in a reward cycle, you’ll have to start stacking before the start of its prepare phase.
Reward slots
Every cycle 4,000 reward slots are available. The minimum amount required to get a reward slot depends on the total amoun of STX that's stacking and can change from cycle to cycle. If you don't meet the minimum, you can pool together with others.
Stacks Token, fuel for a better internet
STX is the native cryptocurrency of the Stacks network. It’s used as fuel for blockchain transactions and enables holders to earn Bitcoin with Stacking.
