Helger Lipmaa (Tartu Universitāte) referāts "Succinct Non-Interactive Zero Knowledge Arguments from Span Programs and Linear Error-Correcting Codes",
Recently, Gennaro, Gentry, Parno and Raykova [GGPR12] proposed an ecient non-interactive zero knowledge argument for Circuit-SAT, based on non-standard notions like conscientious and quadratic span programs. We propose a new non-interactive zero knowledge argument, based on a simple combination of standard span programs (that verify the correctness of every individual gate) and high-distance linear error-correcting codes (that check the consistency of wire assignments). We simplify all steps of the argument. As one of the corollaries, we design an (optimal) wire checker, based on systematic Reed-Solomon codes, of size 8n and degree 4n, while the wire checker from [GGPR12] has size 24n and degree 76n, where n is the circuit size. Importantly, the new argument has constant verier's computation.

After partnering with Wirex, the company was able to add XRP token support to its Visa card. Subsequently, the number of sign-ups and transactions on the platform had a considerable boost.
The very fine qualities of XRP continue to pull users and firms towards itself with the latest addition of Bitcoin Superstore. Earlier this year, Brad Garlinghouse, the CEO of Ripple said the only way of XRP decoupling from Bitcoin influence is through mass adoption.
This movement has supported the saying that the token has more utility than predicted and in fact the firm pushed up ahead and donated millions for humanitarian causes and charity. The first feedback was not that big, however judging from the most recent development Ripple is enjoying the last piece of the cake.
With the above announcement by Bitcoin Superstore via their twitter handle, users can almost in an instant complete settlements with XRP while purchasing from different retail outlets. These outlets being the leading ones like eBay, Amazon and others. If you choose to go for this option remember that XRP in the past has given out results of being cheap for both the merchant offering to accept the token and the user.
Or, even shorter, build a massive, level playing field in which assets can compete to bridge payments, then try to make XRP a winner on that playing field.
This is an ambitious, maybe even crazy, plan. But Ripple has raised tens of millions of dollars, has over a hundred full time employees, and our successes to date speak for themselves. That is, of course, no guarantee of success.
