What is Staking?
-
Can it help me earn passive income with my cryptocurrency?
-
It is risky?
-
And what do I need to know before I get started?
-
Well stick around:
-
here on Crypto Whiteboard Tuesday, we'll answer these questions and more.
-
Hi, I'm Nate Martin from 99Bitcoins.com
-
and welcome to Crypto Whiteboard Tuesday

-
and translate them into plain English.

Today's topic is staking and how it's done on Ethereum.
-
But before we dive into staking
-
let's take a moment to understand the problem that staking tries to solve.
-
Also, if you're new to cryptocurrencies
-
let me suggest that you start with our
-
“what is Bitcoin” and “what is Bitcoin mining” videos
-
before watching this one
-
to gain a solid foundation for what we'll be covering here.
-
Bitcoin and other decentralized cryptocurrencies
-
hold the promise of sending money digitally without any central authority.
-
Initially, the solution to managing a blockchain,
-
which is a fancy term for a ledger of balances that isn't controlled by any one entity,
-
was done through mining.
-
Mining is sort of a competition
-
where powerful computers try to guess the solution to a mathematical question.
-
Whoever finds the solution first,
-
earns the right to write the next page of transactions,
-
also known as a block, into the ledger.
-
With mining, the more powerful computer you use,
-
the more guesses it can make in a second,
-
increasing your chances of winning this contest.
-
Thanks to the laws of math and probability,
-
it is highly unlikely that any single person or group
-
will gain a monopoly over updating the ledger,
-
and that's how decentralization is maintained.
-
Mining's technical term is “proof of work” -
-
because by displaying the right solution,
-
miners prove that they've put in a lot of work,
-
as there is no other way to get to the solution
-
aside from using computing power
-
to constantly work at trying to guess it.
-
Proof of work is what is known as a consensus mechanism
-
since its design is to create an agreement
-
as to who gets to update the ledger amongst a group of people
-
who don't really know each other
-
or have any other basis for working together.
-
While the proof of work consensus mechanism
-
may be a reliable and secure solution for managing a decentralized ledger,
-
it's also very resource intensive.
-
Running all of these supercomputers just for the sake of guessing a number
-
takes up a lot of electricity, among other disadvantages.
-
Because of these disadvantages,
-
other alternative consensus mechanisms have been suggested throughout the years.
-
One very popular alternative is proof of stake.
-
This means that instead of committing electricity to run computers
-
and try to win a contest, people will stake actual coins.
-
But how does this all work?
-
Well, you basically lock a certain amount of funds
-
on an everyday computer that is connected to the network.
-
Your computer is called a node in technical terms
-
and your locked funds are your stake.
-
Once your stake is in place
-
you take part in the contest of which node will get to forge the next block.
-
You see stakers forge blocks, they don't mine them.
-
The winner of this contest is chosen by taking into consideration several factors
-
such as how much money is being staked, how long the coins have been staked for
-
and randomization
-
so that no single entity will gain a monopoly over forging.
-
Generally speaking,
-
whoever wins the contest gets to forge the next block of transactions
-
and is rewarded in coins for his contribution to the network.
-
It is important to note
-
that there are many coins that use proof of stake
-
such as Tezos, Cosmos and Cardano,
-
and each coin has different rules as to how it calculates and distributes rewards.
-
In this video we will focus mainly on how Ethereum's proof of stake model works.
-
Up until 2020,
-
Ethereum's blockchain was based purely on proof of work;
-
but in December of 2020 a new blockchain named “Beacon chain” was set up
-
that uses proof of stake:
-
this is also known as Ethereum 2.0
-
and it runs alongside the original Ethereum blockchain, Ethereum 1.0.
-
In order to join as a validator for Ethereum 2.0
-
you will need to lock up 32 Ether as collateral,
-
which in turn will earn you staking rewards.
-
There's no way to lock up more than 32 Ether on a single node,
-
so if you want to increase your reward
-
you can just set up multiple nodes with 32 Ether each.
-
In a few years,
-
Ethereum 2.0 will deploy in full and will merge with Ethereum 1.0.
-
This event, known as “the docking”, will happen somewhere around 2022,
-
after which Ethereum will become purely a proof of stake network.
-
Only after the docking occurs
-
will you be able to withdraw your staked Ether and rewards,
-
which means that staking is mainly beneficial for long term Ethereum holders.
-
Now you're probably asking how much Ether is rewarded?
-
In Ethereum 2.0 each validator that participates
-
in the forging of a block
-
gets a percentage of the newly minted Ether when it's created.
-
The more validators the network has,
-
the smaller the proportion of the reward will be.
-
For example if 1 million ETH is staked,
-
the max annual reward for each staker could reach 18.10%,
-
however if 3 million Ether are staked,
-
that annual reward rate would drop to 10.45%.
-
You can think of the total amount of new Ether awarded
-
as a pie with a fixed size,
-
and the more validators you have that want a piece of that pie -
-
well, the smaller each slice will be.
-
To simplify things
-
there are dedicated staking calculators you can use
-
that will try and estimate how much Ether you'll make
-
when staking a certain amount of ETH in any certain way.
-
So where do I sign up?
-
Well, signing up is not that easy,
-
as there are certain limitations you should be aware of.
-
Each day, only 900 new validators are allowed on board,
-
so as you can imagine there's a pretty long waiting list.
-
At the time of posting this video
-
there are almost 20,000 pending validators waiting to join.
-
Additionally,
-
setting up your own validator requires technical knowledge,
-
a dedicated computer and 32 Ether -
-
all of which provide barriers
-
that may keep a lot of people from being able to take part.
-
To make matters even more complicated,
-
if you don't set up your validator correctly,
-
or if it goes offline or it is harmful to the network in any way,
-
you may be subject to penalties.
-
These penalties may even include 'slashing' -
-
a term referring to the destruction of portions of your stake
-
and even removal from the network.
-
All of the risks I've just mentioned
-
are why some additional staking solutions were created.
-
These alternatives allow for the everyday person to stake ETH
-
and earn staking rewards -
-
without the considerable effort or risk of running your own node.
-
The easiest way to stake for a non tech savvy person
-
would be to use staking services supplied by exchanges.
-
Certain exchanges allow you to stake your coins
-
through their validators
-
even if you only have a small amount for a fee.
-
This completely eliminates the hassle of running your own validator
-
but requires you to forfeit control over your coins to the exchange.
-
Some exchanges will also allow you to claim your staking rewards immediately
-
and not wait until Ethereum 2.0 reaches the docking phase.
-
Another option is to join a staking pool.
-
Just like mining pools,
-
staking pools are groups of people joined together
-
in order to get a better chance at forging the next block.
-
Staking pools also allow you to deposit less than the minimum staking amount
-
since all of the funds are pooled together.
-
If you decide to go with a staking pool
-
it's important to research certain aspects of the pool;
-
such as reliability of its validators, pool fees, customer support,
-
the size of the pool, user reviews
-
and whether or not you are required to give up your private keys to the pool.
-
Finally, there is the validator as a service option.
-
These are companies that will allow you to run your own validator on their computers
-
without the need to set it up or maintain it.
-
Since this is your own personal validator,
-
you'll still be required to deposit 32 ETH and pay a certain fee for this service.
-
The great thing about this option is that it's relatively easy to set up
-
and you don't need to give control over your coins to another company.
-
That's it for today's episode of Crypto Whiteboard Tuesday.
-
Hopefully by now you understand what staking is -
-
a way of participating in the process of updating a ledger of transactions
-
by putting your funds at stake and earning rewards for your contribution.
-
You may still have some questions.
