Staking vs. Stacking
Understand the key differences
Staking
(e.g. Tezos, Cosmos, Cardano)
Stacking
Only possible with Stacks (STX)
User funds might be slashed based on network activity
Your funds never leave your wallet, and there's no risk of losing them
Requires high uptime and guarantees from nodes
No special hardware required. Users can participate on their own through the STX wallet or through providers
Funds received from staking generally sold to offset maintenance and uptime costs, creating potential for market sell pressure
Earnings are paid in BTC, but the reward generating asset is STX, meaning there is no added sell pressure for STX

FAQ
Where do bitcoin rewards come from?
  • The novel consensus mechanism that connects the two blockchains is called Proof of Transfer. Proof of Transfer is an upgrade to the traditional Proof of Work consensus mechanism used to secure the Bitcoin blockchain and others that have followed.
  • In Proof of Transfer, miners transfer the committed cryptocurrency to some other participant in the network. This allows network participants, who are adding value to new cryptocurrency network, to earn rewards in a base cryptocurrency by actively participating in the consensus algorithm.
  • Miners of the STX chain bid to lead a block and earn the STX coinbase reward by sending Bitcoin. That Bitcoin is sent directly to participating STX hodlers, called "Stackers."
  • Miners arbitrage rates between market value for STX and the cost to lead a block. This makes mining more like an exchange pair, and holders can know that STX will always be priced in Bitcoin.
Can I pool STX to earn rewards?
Pooling is supported at the protocol level through a delegation function. STX holders can delegate their STX to participate in Stacking with others. The Stacks Foundation does not run a pooling service directly, but the Stacking partners listed above provide these options to STX holders interested in Stacking, but don't meet the minimum alone.
