KMD is a verry technical coin. But its sad it got one big flaw in its current setup.

The Trusted Setup is a vital part of what makes KMD work. Kmd is a coin to use a implementation of a cryptographic proof called zk-SNARKs (SNARKS for short). These SNARKS are the engine that can quickly and efficiently verify a transaction and add it to the blockchain without revealing any details to the public. The tricky thing about these SNARKS is that (like many algorithms) they need to have a one time setup. And the reason that this setup is called the Trusted Setup is because you have to trust that whoever generated those keys destroyed them when they were done.

The Keys give "God powers" with the keys its possible to create free KMD for yourself. Because the SNARKS implementation also hide the supply. No one will notice if the keys are beying misused.

i get what your saying. the algo eqihash was used by zcash and they did the same thing. they had multiple trusted people that were given part of the keys. are you saying that kmd did not do this?

interested in this.

thanks

The equihash algorithm is a PoW algorithm and as such doesn't have anything to do with zk-SNARKS. The keys related to zk-SNARKS that KMD uses are the same as Zcash uses. zk-SNARKS are related to only the privacy aspects of KMD and doesn't define the Platform at all. There is dPOW that Einsteinium and Game-Credits projects have adopted to protect from 51% attacks. Then there is the Komodo Custom Consensus Framework that allows for contracts which is currently under development/testing. There are on-chain token generation, on-chain faucet, dice, and Rewards contracts that are already working. So if people can trust the Zcash privacy mechanism, then they can extend the same trust to Komodo's Privacy mechanism as they are exactly the same.

so sab is saying kmd used zk-snarks for the privacy mechanism and in order to do that, kmd had to generate private keys at the begining and kmd has those keys and can use the zk-snarks mechanism to basically generate tokens at will - is this correct?

But KMD didn't generate any keys related to zk-SNARKS. They are using the same parameters as Zcash uses. So if at all there was found to be a compromise in the parameters used by Zcash, then KMD's privacy mechanism is compromised too. But there has been too much discussion about this topic in Zcash related posts and forums and the matter has been put to rest. The only people who bring up the "trusted setup" these days are the ones who invested in other privacy coins.

Komodo is not a purely privacy coin. It is there to use if a user on the platform needs it. What Komodo aims to accomplish and has already accomplished is not for a forum post to say. It is related to Securing Blockchains using BTC's hashpower, Enable interoperability among different Blockchains and provide a powerful Smart contract platform that is aware of other Blockchains among many other things.

Excellent explanation...thank you for making it understandable.
