Any voucher for CCC?
by Giovanni Gherdovich 08 Nov '16

08 Nov '16

Hello, Sorry for writing in English, but I don't speak Czech (yet). I've moved to Prague 6 months ago and I'm not a member of Brmlab; if that counts, I've considered coming to visit the hackerspace, making a donation and join. To the point: I've read at [0] that organizations like hackerspaces might have vouchers for the 33rd Chaos Communication Congress that will be held in Hamburg on Dec 27-30. Do you happen to have one that you don't use? As it happens, vouchers are free of charge but that's not the reason I am asking; today at 20:00 the first wave of presale open to the general public started, and I was there hitting F5 from 20:10 to 21:45 but I couldn't get a ticket. Now it appears to be sold out. There will be two other presale openings in the next weeks [1], but if it goes as today it's hard to get a ticket. Plus, the website CCC is using is on github [2] and it appears people are using bots to get places -- I'd prefer to avoid spending time to do that. Thank you anyways!

Idea je zalozena nauvaze, ze CSIRTy i hackerspace jsou oboje organizace zabyvajici se pocitacovou bezpecnosti, tj by mohlo jit o zajimave spojeni, pricemz vetsina dnesnich CSIRTu je orientovana primarne na "incident handling" v ramci sve infrastruktury, brmlab by mohl byt tim kdo se vic orientuje na verejnost, osvetu, apod. V posledni dobe jsem se venoval nejaky cas pripravam na pripadnou registraci BRM-CSIRT a pro vyplneni registracni prihlasky a rozjeti nejakych aktivit potrebuji vedet jaky typ aktivit hodlame v ramci CSIRTu delat.

[Mini-course: Zerocash and recent developments in Zero-Knowledge proofs]
by Petr Baudis 04 Nov '16

04 Nov '16

Ahoj, kdo se zajimate o nejnovejsi pokroky v oblasti kryptomen a nebojite se matematiky, na ms.mff.cuni bude: (tipl bych si, ze se rozhodne _nejedna_ o "popularizacni" prednasku) ----- Forwarded message from Michal Koucky <koucky(a)iuuk.mff.cuni.cz> ----- Dear All, Ariel Gabizon (Zcash) will give four lectures on recent development in zero-knowledge proofs. He will start by describing the recently launched Zerocash system. The first two lectures are scheduled: Tuesday 8.11. - 15:40-17:20 in S4 Thursday 10.11. - 14:00-15:40 is S11 All are welcome, -- Michal Koucky ------ Title: Recent developments in Zero-Knowledge proofs Speaker: Ariel Gabizon (Zcash) Abstract: Loosely speaking, Zero-Knowledge (ZK) proofs enable one to prove possession of certain information without leaking that information; for example, one could prove that he knows the factors p,q of the number n=p*q, without revealing any information on p and q beyond the fact that their product is n. Until recently, ZK proofs were considered too inefficient and complex to be used for most practical applications. In this short course (I estimate 3-4 meetings), we will review the breakthrough work of Gennaro, Gentry, Parno and Raykova titled "Quadratic Span Programs and Succinct NIZKs without PCPs" and the subsequently developed Pinocchio Protocol that paved way for the use of ZK in practice. We will begin by informally describing how these proofs are used in the Zerocash anonymous electronic payment system; which started as an academic project, but has recently been deployed as a real-world cryptocurrency called Zcash https://z.cash/ ----- End forwarded message -----
