Topic: [ANN] Zcoin (XZC) - Implementing ZKP privacy without trusted setup - page 382. (Read 663349 times)

Not sure what happened, but yesterday I put a few coins into Zerocoin and today I resynced the wallet and I only see the transactions I sent out but the coins are not appearing in Zerocoins so I can't spend them...

Something is really wrong with the wallet, after closing it I had to sync the blockchain all over again. and do I earn something by minting my coins in the Zerocoin tab?

Nice. Finally all fixed. Thanks

I had some DDoS in Suprnova today, but it's all fixed since about 4 hours now


EDIT: Ah I just found a bug, fixed !

Been like this all day today

Dont sell now, this goes much higher.
Wenn we hit bittrex or polo, price goes x10 minimum.

WOW so expensive now, it is good time to sell.

zcoin was already forked from scrypt-n cause gpu asic farm were mining and community ask only cpu.
Now you ask go back to gpu to allow nicehash to point thousand MH on zcoin and let us small miner with only 10-15 gpu get peanuts?
No thanks.

Everything you desire is in the whitepaper.  Stop being lazy.  

From the website (that you supposedly already read):

"Bitcoin and preceding alternative cryptocurrencies have attempted to solve this problem through the use of transaction mixers or ring signatures. However, there are a number of drawbacks to these proposed solutions. For one, a malicious or compromised member of a mixer or ring signature can break privacy. Furthermore, the anonymity set is a key metric to understanding how private a cryptocurrency is. The anonymity set in formerly proposed solutions is limited by the size of the mixing cycle or ring signature. Each mixing cycle or ring signature is limited by the number of transactions per cycle, which is transitively limited by the the block size of the cryptocurrency. Thus, the anonymity set in previous attempts at privacy tends to only be a few hundred transactions.

I've done a little bit of comparison in the Ring CT paper / you can also look here for some facts on zcash- there are a few I've seen so far
1 - Setup: Monero (Trustless) vs Zerocash (Must Trust zcash company)
2 - Proof Generation: Monero (100's /second ) vs Zcash (1/minute)
3 - Algorithm auditability: Monero (a decent number of people seem to understand ring signatures and confidential transactions) vs Zerocash (I'm not sure how many people actually understand the proofs besides the small group of authors) - although this point is certainly subjective.
4 - Poison-pill attack vulnerability: Monero (attacker would need 51%) vs Zerocash Vulnerable, (see zerocash extended paper section 6.4)
5 - Anonymity set: Monero (although the zcash proponents note that a ring signature is a "smaller" anonymity set, they usually don't mention that the stealth address factor actually means that each transaction is masked, whereas the ring signatures provide additional plausible deniability, furthermore, since keys appear in different ring signatures in different blocks in time, the anonymity set for when a given key is spent grows infinitely, and could eventually grow larger than the zcash anonymity set at any fixed instant in time) vs Zcash (anonymity set is the entire blockchain )
6 - Anonymous Multisig: Monero (yes! see "written up" link on ring ct sticky, this could make things like lightning potentially possible ) vs Zerocash (?)
7 - Mining: Monero (has it's own strongly decentralized mining process) vs Zerocash protocol from the paper lacks it's own mining (it's essentially just a distributed anonymous database), so there must be another coin which is mined to convert to zerocash tokens
--note that point 4. is an actual potential compromise of anonymity, which contradicts some of the statements the zerocash team has made.

Thank you, it's good to have a link here. but I read the entire website before I posted here. Lets just wait until someone else answers.

I'm asking you how technology is better than a much more established technology. You're saying subjective stuff like fud and troll. This is my only account. I want to know if I should be interested in zcash and so far I haven't seen a single article that's accurate about competition that shows how it's better. How is it hijacking thread if I'm literally asking you about zcoin. Only reason I brought up zcash is it has some similarities in the trusted set-up which I still don't understand the necessity for. I don't care about xmr being overpumped too fast and falling in value, explain to me why I should buy zerocoin and how it's not just another coin, there are so many people asking these questions and no one seems to be able to answer them. If this was a bitcoin fork, I'd ask why is this better than bitcoin - it's a valid question and your short response lacks any details. I worry you're just an early buyer just trying to promote a coin for trading and not interested in privacy and security in general, so you don't matter, people who want to actually use and hold this tech matter.



If that's true, yeah, that's kind of mean spirited of them. However, every post I've seen was them criticizing security and privacy flaws, not people in general. And as the foremost experts in the field on privacy tech they are often very right, as demonstrated when they deanonimized shadowcash in a day after similarly people were calling their facts fud or trolling or whatever else people say to dismiss critique.

Critique is healthy and necessary if crypto revolving around privacy, security, and safety can succeed. Also p.s. they have never worked on a gui miner or gui wallet so that's why it's not done.

I'm interested in the best privacy coins, my questions are often asked so this would be place to answer them and help me see how I'm wrong.
