Liking this one… very detailed

The discussion whether PoW is better than PoS or vice versa, with all their relative advantages and disadvantages needs to be discussed with a larger audience. For afterall Blockchain is all about consensus, then why not a consensus within a larger community.
If PoW requires huge computing power as a consequence high consumption of electricity, then people must be encouraged to use alternate renewable energy sources. This cannot be a reason to sacrifice the security it provides Visavis less consumption of power associated with PoS.
Entry barriers with PoW are high so not anyone can just join the network to validate the transactions which can be the case with PoS.
The very idea of Blockchain is decentralized trustless transactions without the involvement of third parties, so then what purpose Casper and such serve ?

can someone anwser my questions

what did you mean by bets ?

is the forgers create blocs like in the POW ? and how they create it technically?

is the forgers have to stake and in the same time instale a node in his computer ?

is that node a piece of code that validate & confirm txs automaticaly ?

is the forgers has the ability to on/off that node ? and what happens if they do that ?

how this node can know if this tx are valide/legal or not ?

is this node use some computer ressources ? CPU … ?

how the other supply of coins in POS protocol minted or released ? (in total supply)

how the validator can create an invalide bloc ?


It looks like Vitalik and Ethereum team have a plethora of interwoven and conflicting interests to solve. I will start with the biggest agency problem everyone is ignoring: 1) How to give the VC’s bankrolling Ethereum a clean exit with expected returns of >20x on exit. They will be pushing hard for POS as it will create scarcity of ETH and push up their token holdings vastly for an exit. We should not ignore that the VC’s interests and ETH community interests might be wholly orthogonal to each other. 2) How to keep the little guy vested and reward his/her loyalty to maintaining the integrity of the blockchain? Is this not the whole point of blockchain? Decentralized and distributed custodians of trust? Heads up! That ideal is long dead with mining pools creating hidden centralized power structures whose interests might not always be best aligned to the future of ETH nor the little minnows contributing to their pools. So, while moving this hidden centralized (concentration of control) to POS will certainly free up restrictions for the Ethereum developers to make changes, it will not democratize anything. 3) Who is being rewarded for what economic value? This is a fundamental question that needs to be clarified. Simply having ‘staking pools’ as trust agents is going to create other imbalances. Who is going to pay for the processing of trust (transaction verification)? What is the infrastructure going to look like? Or is that also going to get centralized as we already have in banks and effectively shafting all the minnows? If someone ‘stakes’ a very large amount of ETH, but has no supporting hardware to process transactions, what is his/her economic value? When you buy bonds/equity and get a yield, you are lending money to another entity that will invest that money… Read more »
