Topic: Proof of Stake Questions (Read 213 times)

It is because I heard that forgers were randomly chosen according to the time they are in the network and the amount of coins in staking. But I wanted to understand more about how this process occurs in a decentralized network.

You should put source on your statement especially if you 100% copy/paste your post on a certain website to avoid plagiarism. The content of your post is fitted on OP question but you should not own as if you are the one who constructed the whole thought.

Atleast tag the source which is here: https://antliablockchain.medium.com/exploring-the-consensus-algorithms-in-blockchain-54c737ac1b92

@OP, This might help you to learn the general overview of Pos, I don't know what's in your mind but you are just making things complicated, You are asking who choose the forger while it's obviously on random basis written on the code.

Widely regarded as the most viable alternative to Proof of Work. A PoS consensus algorithm steers clear of miners, hardware, and huge energy challenges. It aims to provide a more elegant solution to the shortcomings of PoW.
The validators in the system agree to place forward a part of their stake. Unlike PoW, no external resource is invested rather validators lay down the internal resource – cryptocurrency. The node which places the highest stake gets the chance to validate the block first. Nodes with smaller stakes validate the block afterward. However, instead of rewarding the node which quickly solves the puzzle first, all nodes are rewarded according to their respective stake in the system.

Antlia uses another variation of PoS known as a rollover Proof of Stake (rPoS). In this system a number of validators will be selected; the validators set will not be fixed but rollover. The rPoS engine will randomly search for the validators on the basis of a number of factors such as health, liveness and safety. After every 50 blocks “roughly every 02 minutes”, a new set of validators will be selected from the pool with a 10% rollover rate i.e. within the five blocks mining time duration, the validator pool undergoes following changes:
The validators will be sorted in the ascending fashion on the basis of health, liveness and safety. Validators having best health comes first and vice versa.
The last 10% of the validators will be swapped with the new ones on the basis of the algorithm.
This sorting and swapping will allow new validators to enter, making the system more decentralized and trustless.

For any distributed network to work, achieving consensus on the validation process is important. It is due to the mutual agreement that blockchains are thriving and undergoing rapid growth. From monetary transactions to data sharing, verifications of the blocks is critical.

You can easily find answers to your questions online using Google search and thanks to those who've already provide details or the definition of proof of stake, here is a advice for newbies, POS earnings is less risky compare to farming earnings from DeFi projects that smells like HYIP investments. Do your own research and have good knowledge before diving in.

First coins also can be generated with proof-of-work.


Block signer selection is defined by specific implementation of proof-of-stake.

Least hash value? Tell me more, please.

But who / what does this random selection?

There are various methods of selecting forgers in a PoS network but the commonest ones are randomized block selection and coin age based selection. In the random selection method which you asked of, the algorithm selects the user having the combination of the least hash value and amount of coin/token staked. All other things being equal, the higher the stake, the higher the chances of being selected

And I know that the older you are in the network and the richer you are, the more chance you have to be the forger of a block, but I don't know how exactly the forger is randomly selected in a decentralized network.

Sorry for the stupid question, I know it is decentralized, but I heard that a forger was randomly chosen to forge a block, and I know this is a simplicity, but ... I don't know how it happens in a decentralized network.

You keep asking the same question even though people have answered it and gave you links to read.


There's a group of chimps sitting in a big room and pressing buttons 24/7. Each user has a button assigned and if that button gets pressed by a monkey the reward goes to the user.

It's the same in PoW with the difference that each user has to buy a mining machine in order to get a button assigned.

3 - Who selects/chooses randomly block forgers?

I'm following ETH, but I didn't know that PoS-based economies couldn't be independent. Thank you very much for answering me.
But who chooses/selects block forgers?

Have you been following PoS project like Tron or EOS?
First, they all started out as ICOs issuing tokens created on Ethereum network and as we all know at the moment, PoS protocols are not possible on Ethereum, so they then migrated to their main nets and started carrying out swap processes where for example, for every EOS ERC20 token, an EOS coin that can operate on the EOS main net is minted, while the EOS ERC20 token is sent to a burn address. So the first coins are just minted. It's not a miracle.

How are the first coins generated?

The block validators are rewarded with minted coins, These are the coins that end up in circulation


The consensus algorithms used to select validators are random for a reason and the higher number of coins one has staked, the higher the chances of one validating the next block. So there is no possibility of two conflicting blockchains, it's one validator at a time.

All the answers to your questions can be googled.

Every PoS coin is a program written in a code and staking share distribution is based on that code. Like it can give you additional rewards for the age of your stake so the longer you stake the more you get.

By a conflicting blockchain you must mean a fork. In such case people who stake have to decide if they want to remain in the old chain or follow the fork just like in PoW.

Everyone does validate as long as you have a balance to stake with.

I cannot answer or understand this question. Perhaps the community can answer this.
Percentage of your holdings affected the rewards, example the block reward is 10, the 10 tokens will be distributed to all stakers. The reward everyone receives is different from another.

What is POS.

Three questions:

1 - How are the coins generated in a proof of stake economy?
2 - If there are two conflicting blockchains, how do I know which one is the real?
3 - Who selects the node to validate the next block (I know it's random, but who calculates the random)?

You can say that "the validators vote", but if they are conflicting since its origins?
