Q&A - EOS Stake: What Is The Stake & Unstake Mechanism?

June 20, 2018 / by Alexandre Bourget

Alexandre walks through the terms staked and unstaked EOS tokens that you may have heard. When the EOS mainnet was launched, all accounts began with tokens in three different states: 'free floating,' 'staked for CPU,' and 'staked for Bandwidth.'

What is it with all that stake? So let me explain what's the staking and unstaking mechanism, how it relates to the chain unlock, and how you can see your total balance.

So when we started the chain, everyone who bought into the crowd sale, transferred their EOS onto the new chain. But they were started staked for the most part. If you had more than 11 EOS then you were kept with only 10 EOS floating. Floating meaning you can transfer them today to someone else to pay for pizza. But all the rest was staked for CPU and bandwidth.

What does that mean? If you stake your coin, you're sort of paying an opportunity cost. you can't unstake them until three days after you did that operation, and it means you can't access them. That little cost there is what grants you access to the system. The fact that you can't spend them for the next three days. If you stake them for bandwidth, it means you can send transactions, and the size of transaction will consume your bandwidth. It's going to be tailored into your account, and the CPU staking is in terms of milliseconds. We're not Amazon here, so it's not like big servers, it's operations that are going to be done through the blockchain, and it's going to be computed in microseconds or milliseconds. If you don't consume much of your bandwidth, it'll accumulate so you can have a burst when you need to have a lot of transaction go through.

So for the most part, people will have plenty of space there if you just stake one EOS or two, if you don't use the chain that much. But this is how the resource limiting is applied on EOS. It's also your voting power. What you stake, you're paying that opportunity cost and this gives you weight to vote on your preferred block producers.
Now some might say "well I don't have my full amount there." But you need to make sure to check both staked as CPU and bandwidth. The sum of those things, plus what is free floating, and then you need to check that in your currency balance. Probably you have two EOS or ten EOS in there, the sum of all these things is what you own. So sometimes you can be confused. You'll have CPU and network. If they're the same value, it's not that you have half of it you have both of them. When you unstake them, you can get the full refund of those after three days after the last undelegate bandwidth or stake and unstake operation.

So just to be clear we talked about stake and unstake, but the operation on the blockchain is called `delegatebw` or `undelegatebw`. This is the same thing as stake/unstake.
