What Are Zero-Knowledge Proofs? Complete Beginner's Guide
Bitcoin Zero Official Sub-Reddit
BitcoinZero is the forked coin which utilizes the Zerocoin protocol, a zero-knowledge proof system that does not rely on a trusted setup. This will provide users with full anonymity! Official Website: https://www.bitcoinzerox.net/
Bitcoin and most cryptocurrencies expose your entire payment history to the public. Zcash is the first open, permissionless cryptocurrency that can fully protect the privacy of transactions using zero-knowledge cryptography.
Snowden: Monero's privacy is primariy protected by the idea of Ring Signatures, which, while a huge step up from Bitcoin, are closer to a mechanism for "plausible deniability" than the true privacy intended by the zero-knowledge proofs used by Zcash.
ZCASH AND ENHANCED BITCOIN USING ZERO-KNOWLEDGE PROOF TECHNOLOGY.
Zcash is basically refered to as a crypto asset or cryptocurrency which basically provides to its users a greater protection in terms of securing their privacy. Zcash is like a revamped Bitcoin model despite been developed on bitcoin infrastructure, it also makes use of zero-knowledge proof technology which is called a Zk-SNARKs and its essence is to conceal users infor. The Zk- SNARKS protocol that runs on pure mathematical theory. Bounty #SERO #Privacy #Blockchain# For more information https://sero.cash/
Our cryptographers are still in the thick of it at Tel Aviv Blockchain Week! Catch Ben Fisch tomorrow and Thursday at Scaling Bitcoin, where he's giving the invited talk: "A Survey of Progress in Succinct Zero Knowledge Proofs: Towards Trustless SNARKs".
Can zcoin zero knowledge proofs be implemented on an existing chain such as bitcoin cash?
From what I understand zcoin is very similar to bitcoin cash regarding wallet seed generation etc. But it has the added feature for burning and minting new coins with zero-knowledge proof. Can this feature be integrated into an existing chain like bitcoin cash for example? - Maybe as a hardfork upgrade for example? - I am just thinking that if this technology matures and proves to be the way to go (or at least a great option to have there if needed)... if what you really care about is global adoption etc... you'd be better off just adding it to a chain that already has widespread merchant adoption and user base etc.
I’m 25 years old with literally zero dollars and zero knowledge of financial anything. Should I look into bitcoin or am I an idiot?
I’m just seeing this thing EVERYWHERE, wether it’s a couple friends on my social media or plastered throughout reddit. I just want to know if I should continue to look into this with zero background knowledge on the subject
The Z-address, the T-address, and Bitcoin Private zero knowledge proof
I'm now heavily invested in Zclassic, in order to get some bitcoin private. Not because of the heavy gains from announcements, but largely because this fork is one of the most interesting forks I've seen to date. This won't be a price discussion, because there already is enough of that going around. I'm very interested in how Zclassic and BTC will merge histories from two coins into one. I noticed that Zclassic has two types of addresses. A Z-address, which I assume uses some sort of zero knowledge proof. Possibly Zk-SNARKs. (If you want to learn more about the zero knowledge proof, find the analogy of the two colored balls and the color blind friend). Zclassic also has a T address which starts with a T for transparent and is apparently similar to a bitcoin address. I also assume this means it uses SHA-256 proof of work to verify validity of transactions. You will find a t-address used as the development teams donation address. Note the t at the beginning of the address. ( t1gsePJZ6ojJYygj3PWMGJfojPUoMd5AVfU please donate to their development! ). You also will find a t-address as your address on any exchange. I'm guessing this means everyone is still largely using t addresses. Here are some questions that come out of this research. * Will BTCP all be z addresses, or another mix of Z and T? * Can you convert previous transparent chain blocks to a private address? * Can I send Z coins to a T address? I love the idea of zero knowledge proofs, and the zk-SNARKs philosophy seems brilliant. I'm excited for the upcoming weeks to see what bitcoin private can add to the crypto community.
WSJ Article "Bitcoin is Worth Zero" is scaring my investor friends. Can someone with more knowledgeable expertise please assess the claims in this article and their merit?
It would be helpful for us all to understand possible issues and arguments against bitcoin, even if the majority of us are fans and HODLers. Here is the mirror I found: https://i.imgur.com/UFn64Gp.png Claims in the article:
I'm inclined to say Bitcoin is worth $0, especially if Bitcoin's value depends on it being adopted as a global digital currency to replace dollars
No chance Bitcoin can replace dollar because it's badly designed. It can handle a pathetically small number of transactions, and used an inordinate amount of electricity to do so, making it entirely unsuitable to replace ordinary money
Even if Bitcoin worked better, it is in a Catch-22 because of Gresham’s law, the nostrum that bad money drives out good. Given the choice of spending inflationary government-issued money or something which holds its value, everyone would spend the bad paper stuff and hoard the Bitcoin. You wouldn’t want to be the person who spent 10,000 Bitcoins on two pizzas in 2010, when a Bitcoin was worth a fraction of a cent. Those Bitcoins are now worth $40 million. But if no one spends Bitcoin, it will never get established as a currency.
In any currency, the money supply multiplied by how often it circulates equals the price level times the number of transactions. For Bitcoin we can estimate three of the four variables, Mr. Davies says. He observed that even hardened criminals don’t set prices in Bitcoin, but rather in dollars, and then immediately convert. Assume that all drug dealing moves online, that Bitcoins circulate as fast as ordinary currencies, and estimate a $120 billion-a-year market for illegal drugs, and the formula spits out an ultimate value of $571 for a single Bitcoin. The more drugs traded, the higher the value, and the more Bitcoin hoarded rather than spent, the higher the value. Drug dealers might be willing to put up with the limitations of Bitcoin, notably the uncertain time taken to complete a purchase and the high transaction costs. Laundering dollars is more expensive. But studies cited by the United Nations Office on Drugs and Crime suggest that cryptocurrency-based online drug dealing remains relatively small, and focused on retail, meaning fewer and smaller transactions than Mr. Davies’ limiting assumption, so justifying a much lower Bitcoin price.
On this basis the current price of $3,950 is mostly speculation, and J.P. Morgan Chase & Co. Chief Executive James Dimon’s comparison to the 17th-century Dutch tulip mania is apt.
Digital gold might be more appealing for Bitcoin’s true believers, who would surely prefer to avoid basing a currency on illegal activity. Gold is hopeless if you want to pay the mortgage or buy bread, but is useful insurance because we can be confident that if a government currency collapses the shiny metal will roughly hold its value. It helps that history holds plenty of examples of currencies losing all their value to hyperinflation while gold could still be bartered for food and shelter.
Gold has a value far above what is justified by its uses in electronics and jewelry only because (almost) everyone agrees that it has value. That “network effect” is what Bitcoin needs to establish itself, and the more attention it garners, the more likely it is to become established. Yet, gold has had thousands of years and a history of being used to back money to support its position. Technological disruption may be overturning many societal norms, but securing society-wide recognition as a safe asset takes more than the backing of tech evangelists and a bunch of get-rich-quick stock promoters.
Still, the potential to replace gold gives us some figures to work with. Thomson Reuters GFMS estimates there were 2,155 metric tons of gold held in exchange-traded funds. Switch all of that into Bitcoin and it would justify a price of about $5,500 for the 17 million Bitcoins currently outstanding.
We could be more optimistic and think Bitcoin might replace gold coins and bars. Leave aside that the gold is better than Bitcoin because gold doesn’t depend on having an electricity supply, and the 24,000 metric tons GFMS estimates have been bought for investment in the past half-century would justify a price of $61,000 for every Bitcoin.
If we assume that Bitcoin will either succeed completely in displacing gold or fail and be worth zero, it helps explain why the digital token has been so incredibly volatile, with a 40% loss in two weeks, and a 33% rebound since Friday’s low. Based on the simple choice between total success and failure, we can very roughly say that Bitcoin at 70% of the gold ETF-derived price suggests a 70% chance of displacing so-called paper gold as society’s chosen emergency store of value, and a 6% chance of displacing physical gold. Even digital dreamers should accept that is far too high.
Spideroak.com - zero-knowledge private storage, share and sync. Should we accept Bitcoin and become 100% anonymous? (We don't store customer data so we already are, but I know..)
Just looking for feedback, support or not. A limited trial will start shortly but as a bitcoin supporter I am simply wondering.. Is there any interest? Also. Have questions? Shoot us an email and i will answer: [email protected]
Zero-knowledge proofs are one of the more abstract and fascinating concepts in applied cryptography today. From potentially being applied to nuclear disarmament talks to providing anonymous and secure transactions for public blockchain networks, zero-knowledge proofs are a profound example of cryptographic innovation. In short, Bitcoin Zero is designed to bring zk-SNARK (Zero-Knowledge Suc- cinct Non-Interactive Argument of Knowledge) back to Bitcoin. The journey of ’zero’ started from zerocoin (Miers et al., 2013) a cryptographic extension to Bitcoin including utilizing non-interactive zero-knowledge proofs; Then, zero- cash (Sasson et al., 2014) formulated and constructed decentralized anonymous ... A zero-knowledge proof lets someone prove a mathematical fact to another person without teaching them anything about the fact itself. It has been proven that you can convert any computer program into a zero-knowledge proof (this is referred to mathematically as PSPACE⊂IP). So, using a zero-knowledge proof I could prove to you that I know some ... Like Bitcoin, Bitzec transaction data is posted to a public blockchain; but unlike Bitcoin, Bitzec ensures your personal and transaction data remain completely confidential. Zero-knowledge proofs allow transactions to be verified without revealing the sender, receiver or transaction amount. Selective disclosure features within Bitzec allow a user to share some transaction details, for purposes ... Zero Knowledge is a podcast which goes deep into the tech that will power the emerging decentralised web and the community building this. The podcast is made for fellow developers and people looking to educate themselves on the inner workings of the space. We are non-speculative and focus on the tech.
