Start Stacking

A new way to earn Bitcoin

Stacking is locking your STX temporarily to support the network’s security and consensus. As a reward, you’ll earn the Bitcoin that miners transfer as part of Proof of Transfer.

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.

About Proof of Transfer

Earn rewards

When you stack, you can earn Bitcoin every cycle (a collection of Bitcoin blocks). How much you’ll earn can vary from cycle to cycle depending on how much BTC miners transfer and how much STX participates.

The reward model

Meet the requirements

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. To participate, you need to meet the minimum amount of STX for a full reward slot or pool together with others.

Start Stacking

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 using a service

Even if you don't meet the minimum, you can still stack and earn Bitcoin by delegating to a service that stacks on your behalf. The service will pool STX together and distribute rewards back to the participants.

How Stacking works

Reward cycles

Bitcoin is paid out in cycles. Every cycle each stacker has the chance to receive Bitcoin once for every reward slot they hold. A cycle typically lasts for 2,000 Bitcoin blocks, or approximately 16 days 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

Depending on how much you’re Stacking, you can hold one or more reward slots for a given cycle. The minimum required for a reward slot varies depending on how much STX is stacking. If you don’t meet the minimum, you can still earn rewards by delegating or pooling your STX.

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.
