Bitcoin is not anonymous and is subject to flow analysis. Zcash and monero have solved this in different ways with really intriguing primitives. ZCash uses zksnarks which are a pseudo homomorphic encryption strategy to hide payments whereas

To reach a ketogenic state, the term fast from a clinical sense required 24-36 hour period without any caloric intake; strictly water. I have done 3 day water fasts, the hunger waves need to be controlled the first 2 days, but the feeling

For those who are price sensitive like me but want all our macros; my personal app also scrapes the flyer for local grocery stores for ingredient prices and runs a knapsack algo to reach my cost threshold and tells me what things I can mak

Indexing is important for sure. The problem is to preserve privacy and not falling back to heavy weight general purpose Multi-party computation we have to give up a bit on the precision and recall of modern search engines. Minhash, more s

One step further that Ive prototyped is Encrypted and Distributed Search. The VPN relays willing to take the traffic can also double as Web crawlers. The vpn clients encrypt their search terms and vpn relays encrypt their search indexes,

I overcame TDMA problems associated with mesh broadcast networks by moving channel allocation logic into the application layer. For me it was more important for reliable delivery then bandwidth. We use geo spatial TDMA to further allocate

Probably for its homomorphic encryption properties. Used in the correct setting with the appropriate Generator ( ElGamal on Elliptic Curve Fields) it is very secure but limited in use beyond Set Intersection as the results cannot be decryp

Starlink I think can consider heavily leveraging a multicast or hypercast protocol considering most bandwidth usage is related to video streams. Many downlinks can accept a broadcast level packet. How does a system link Starlink handle cha

I think ultimately the price will be determined through government subsidies. Current Meat and Dairy Industry receives massive subsidies (~38$Bn) and the lobbying groups won't appreciate a cut of profits.

The uptake will be great however, what doesnt sit well is the 2008 12Billion bailout. As the same actors will be the nodes that are privileged to write to and maintain the ledger, it has yet to be seen how immutable these transactions will

It is a computation platform first and foremost. You can pay gas in ETH. Every opcode has a set gas price, so executing a compiled contract on the network costs you some ETH. Why would you want to run code on ETH? Most notably, it requir

from my experience, erlang actor model had some of the strongest queue mechanics and the most resilient systems I have deployed. As some background, I worked as a contractor for a telco and built a 6 9's system for their service monit

1) Can you clarify which users? The government issuing the search query is unable to decrypt the messages. If they flag it, they can order a warrant against the individual to decrypt the message. 2) A random salt is used so only exact keyw

Im hoping to resolve this using a "searchable encryption" scheme leveraging homomorphic encryption and elliptic curve based el-gamal. This would allow law enforcement to search for key words on encrypted data sets. This prevents

I imagine a decentralized search service for a particular set of search queries that users want privacy against. it leverages Additive and Multiplicative Homomorphic Encryption with Elliptic Curves. I wanted a fuzzy searching algorithm so

I started working on fuzzy matching searchable encryption for this very reason; you can send an encrypted search term and match using jaccard similarity to an encrypted index of similar documents without information leakage of the search qu

How is adsense able to complete this? I assume Google is the broker and thus completes on the match on their servers.

How is ad matching performed exactly? Is a users data profile basically matched against some set of ad network defined properties and then served to the end user?

HN community definitely is an echo chamber when it comes to cryptocurrencies and its a shame. My question to my fellow HNers is do we see no merit in a censorship resistant framework which builds a trustless execution environment. I dont t
