Vitalik Buterin via the Vitalik Buterin Blog This is a mirror of the post at https://medium.com/@VitalikButerin/zk-snarks-under-the-hood-b33151a013f6 This is the third part of a series of articles explaining how the technology behind zk-SNARKs works; the previous articles on quadratic arithmetic programs and elliptic curve pairings are required reading, and this article will assume knowledge of both concepts. Basic knowledge of what zk-SNARKs are and what they do is also assumed. See also Christian Reitwiessner's article here for another technical introduction. In the previous articles, we introduced the quadratic arithmetic program, a

Vitalik Buterin via the Vitalik Buterin Blog This is a mirror of the post at https://medium.com/@VitalikButerin/exploring-elliptic-curve-pairings-c73c1864e627 Trigger warning: math. One of the key cryptographic primitives behind various constructions, including deterministic threshold signatures, zk-SNARKs and other simpler forms of zero-knowledge proofs is the elliptic curve pairing. Elliptic curve pairings (or "bilinear maps") are a recent addition to a 30-year-long history of using elliptic curves for cryptographic applications including encryption and digital signatures; pairings introduce a form of "encrypted multiplication", greatly expanding what elliptic curve-based protocols can do. The purpose of this

Vitalik Buterin via the Vitalik Buterin Blog This is a mirror of the post at https://medium.com/@VitalikButerin/quadratic-arithmetic-programs-from-zero-to-hero-f6d558cea649 There has been a lot of interest lately in the technology behind zk-SNARKs, and people are increasingly trying to demystify something that many have come to call "moon math" due to its perceived sheer indecipherable complexity. zk-SNARKs are indeed quite challenging to grasp, especially due to the sheer number of moving parts that need to come together for the whole thing to work, but if we break the technology down piece by piece then

A service created to aid dark web users in uncovering compromised BTC addresses has been shut down after gaining the attention of state regulators. Sponsored Sponsored Antinalysis, a blockchain analytics tool that allows Bitcoin addresses to e checked to criminal activity has suspended operations. According to Elliptic, the tool allows cryptocurrency launderers to see if funds will be tagged as illegal funds by regulated exchanges before making a transaction. Elliptic provides regulated cryptocurrency exchanges tools to check customers’ deposit links to any illegal or illicit activity they may be connected to.

In June 2019, the intergovernmental Financial Action Task Force (FATF) introduced its revised set of standards for virtual asset service providers. The document establishes the anti-money laundering and counter-terrorism (AML/CFT) requirements that regulated VASPs — the term mainly referring to cryptocurrency trading platforms — must eventually implement in their day-to-day operations. The guidelines are framed as recommendations, and the FATF leaves it to the participating nations’ governments to develop their own regulations in accordance with suggested principles.The watchdog has also set a 12-month review timeframe to monitor the public and

He is a 17-year old hacker, Graham Ivan Clark, who went by the alias ‘Kirk’ during the hack apparently went overboard with their plans to sell the unique Twitter account.
