As of yet, proof of stake hasn’t really been tested vs nation state level actors. (An assumption but I could be wrong). Does anyone have any good documentation on papers or arguments as to why PoS (and cardano’d implementation in particular) is resistant to meddling by highly competent adversaries.
As far as I know if a validator tries to do an illegal thing system punish them but what is the punishment amount is there a formula to calculate this ?
Hi, any Ethereum developer here or someone with knowledge about the roadmap of Casper PoS? I read that the last update for the chain was "Istanbul", right? I would like to know which are the still outstanding updates to come in this year 2020?
And which one of them will be a "hard fork" category?
And does "hard fork" update mean that there will be another coin "created" just like ETC? Or will this all be ideally work out without the result of another coin?
Thanks all
Everyone likes getting something with little to no effort, which is why the idea of getting a passive income with cryptocurrency attracts a lot of attention. There are a few different methods that enable crypto traders to earn crypto passively. Whatever the method, they can utilize the crypto they are holding and get something in return. Staking is one such way to achieve this. Not only can users earn rewards through PoS, but they can also feel good knowing that they are playing an integral role in securing promising blockchain developments.

Can someone explain how Cardano's Ouroboros proof of stake protocol is different/better than other previous and current proof of stake protocols? I know it's the first provably secure POS protocol, but does that mean the others are not secure, and have there been successful attacks against other POS protocols? I am just trying to better understand what "provably secure" means and how that differentiates Cardano's POS from other POS protocols.
What exactly makes Ouroboros provably secure and others not? I am thinking of other POS systems like NXT and Tezos, what is the difference between those examples and Cardano's POS?
I did a search on this reddit. This question was asked three years ago and needs a better answer so I ask again...
Can a MW based blockchain be secured via Proof-of-Stake vs. Proof-of-Work? Is there any altcoin working on development of this technology?
**ADDED 10/26/2019**
On further thought... I have been reading about the protocole and I fear the answer to my question is "no, MW and POS are not compatible". Please correct me on this point if I am wrong. My reasoning is that in MW, as I understand it, there is no balance information stored on the ledger. There are also no addresses. As such, I don't know that it could work with POS because there is no way to prove that you have stake.
I would really like someone to clarify this for me further as it seems that a MW based POS coin (assuming for a minute it could be fairly distributed which is a different problem) would be an amazing coin.
Hi,
After the Binance hack of it was discussed if it would be feasible to reorganize the blockchain, find a consortium of miners that would start mining again from the block number before the theft happened.
It was concluded that it's not possible or too complicated, the economics(mining costs too high) would not work and risks are too high.
In a future scenario of Proof of stake, what is the main mechanism to prevent rollbacks or reorganizations of the blockchain.
Would a Binance hack of Ethereum be easier to roll back?
Thank you for your answers
Think of it: Not the miners earn the transaktionfees, but the stakeholder for relaying the payments. This system makes the rich richer, without the need for them to provide any work.
