North East Texas Technologies views. Buy signals bitcoin ethereum is it worth it just had a meeting with str4ddairaebfullzookozcashand myself, and we arrived at these conclusions: Given all of that, I'm in favor of including this new Sprout implementation as part of the Sapling upgrade. At the same time, the new consensus rules will reject using the old Sprout proving system and the First-Ceremony-parameters for Sprout-note-spends. You're right that a network-observing adversary can potentially see which node introduced the transaction to the network, and therefore can add up the balances transferred by node. Because if there's a bug or Toxic Waste in the new system, you can counterfeit money using the new Sapling circuit. However, Zcash has one secret key and it holds significantly more importance. This is not true; contrary to popular the ceremony zcash zcash benchmark, Bitcoin is far from anonymous. We might introduce new bugs. Whoops, I see this is redundant with some earlier comments that hadn't loaded when I wrote this: Don't like this video? The new implementation is faster. Copy link Quote reply. More Report Need to report the video? However, if the bugs affect any of Sapling it's already game over, and if we faithfully port any Sprout circuit bugs, this approach doesn't make that worse. Observe Sapling adoption and figure the realistic schedule for obsoleting Sprout notes. On the other, the security of the entire network is predicated on this blinding factor.

I am not quite sure that I follow everything since I am not too familiar with the terminology. I hope that ZCash will choose privacy and user protection over some faulty notion of fixing old mistakes which cannot be fixed. It also indefinitely puts off a public proof that no zSprout inflation ever occurred. You can just call it bellman for now I suppose. If somebody got a hold of it, he or she could successfully make counterfeit Zcash tokens.

If somebody got a hold of it, he or she could successfully make counterfeit Zcash tokens. If those exist currently ripple cryptocurrency where to purchase turbotax and cryptocurrency are easy to attack by anyone who can submit a transaction. In addition, two new privacy coins, Grin and Beam, launched in January and are generating a lot of recent buzz in the industry. While one may reduce to the other, I'm not aware of such a reduction. The independent nodes all over the world elect a subset of nodes to manage the network. That was discussed and decided in There are ways, using math, to make this possible, which is an amazing and potentially game-changing concept. The drawbacks include: If the current Sprout verifier code becomes a bottleneck e. CryptoKitties, a decentralized app where you can collect and trade digital kitties, nearly crashed Ethereum at the end of because of the congestion in processing trades. For future epoch transitions it might be possible to do a private turnstile; see and This comment has been minimized. However, if the bugs affect any of Sapling it's already game over, and if we faithfully port any Sprout circuit bugs, this approach doesn't make that worse. OTOH I'm somewhat skeptical that such a thing would a good use of our time and resources. This captures the trade-off between Zcash and Monero. Loading more suggestions

Or just direct them to Jason Davies's. Neither are perfect, which is why other privacy coins Grin and Beam, for example have continued to launch. Nevertheless, there are multiple blockchains that have been engineered to be private. If you exploited the Sprout circuit while it was enabled in order to violate global balance, and then privately transferred the funds to the Sapling value pool as is being suggested here, there would be no way to detect that, even if the Sapling circuit and setup were flawless.

Related Topics: I didn't realize there would be this much performance benefit —more than a factor of 2 in both memory and proving time— just from moving to Groth This does make me a little more favourable to the proposal of just copying the Sprout circuit with a transparent turnstile. It still makes v3 transactions created by existing code invalid after Sapling activation which was not the case for the current plan. This comment has been minimized. The major ones, based on their technical proficiency and the market cap of their associated cryptocurrencies, are Monero and Zcash.

Only the net amounts moving out-of-zSprout and into-zSapling would necessarily be revealed - not source or destination addresses. If we are creating a new shielded value pool at that time due to fundamental circuit changes, or for turnstile auditing of the monetary base , it would make sense to target that value pool instead of the Sapling one. Perhaps users who don't care at all about privacy are willing to accept the turnstile but that just means that this change would mainly hurt the people that care most about privacy and are likely the most vulnerable. The benefits include: Deprecating v3 so quickly after its introduction may be costly for some vendors, especially hardware wallets. Something I forgot to mention in the meeting: Note that a Sprout circuit using Groth16 and bellman wouldn't be very much more efficient per-input than the current Sprout circuit implementation, unless we were to recompute the Sprout commitment tree using Pedersen hashes which is possible. Edited to include the fact that we would redo the circuit using Bellman, too, thus protecting against bugs in the original circuit per the first comment. Possible extreme-minority opinion here: Because we are putting effort into porting the new Sapling stack into multiple other contexts mobile, potentially hardware wallets, SPV wallets this might also streamline porting z1 support to those contexts, along with any general Bellman resource improvements ex:

Whoops, I see this is redundant with some earlier comments that hadn't loaded when I wrote this: The new implementation will be on the Bellman stack, so all proving will now be on a single consistent purpose-built stack. So we believe this "tight schedule" hurdle is already present, and this decision doesn't add much beyond. Zcash allows users, both senders and receivers, to choose whether they want their transaction information to be transparent or shielded. One of the major problems with the optional privacy features of Zcash is that if the majority of the network opts out of the privacy feature, it becomes easier for surveyors to track the private users.

This is not true; contrary to popular belief, Bitcoin is far from anonymous. Yes, about twice as fast but still much slower than Sapling. Already on GitHub? After the protocol upgrade, any compromise or weakness of the original proving system or MPC setup can no longer be attacked. So, no changes to parsers necessary. Thus privacy blockchains and scalability progress are intimately linked. It also indefinitely puts off a public proof that no zSprout inflation ever occurred. There may be some merit in doing it with every upgrade, but the advantages are especially apparent in the upgrade from Sprout to Sapling. Forcing users to reveal their balances seems like a breach of contract to me. Aleksandr Povozkov.

It does not neutralize it for privacy or for "on-line" coinbase app review will ripple go up in value where the attack must be directed toward a specific victim, but note that privacy as far as the circuit is concerned is dependent on the zero-knowledge property of the proving system, which is quite robust to [non-memory-safety-related] errors in the circuit implementation, so that it is less likely that reimplementing the circuit helps against that class of attacks. This comment has been minimized. However, I definitely am strongly opposed to what I believe you call the turnstile. I think that revealing the net amounts and distribution of money breaks the privacy that ZCash promises to provide to its users. Or just direct them to Jason Davies's.

There are two different scenarios and for either of them "not forking" seems to be the dominant strategy: However, the more nodes there are, the more servers decisions are processed through, and thus the longer it takes to agree on a decision. In fact, shoehorning the Groth16 proofs into the PHGR13 slot without changing the version or nVersionGroupId would be breaking a design rule about unambiguous parsability.
