Bitcoin Network Recovery – $40 Billion Of Self-Inflicted Damage

After 1 month of acute crisis the bitcoin network is finally operating more or less normally. Imagine that you went to a station in rush hour and it took you 1 month to get home due tube or rail network jamming. This is exactly what happened to bitcoin in the last 2-3 months, and which is …

Post-Quantum RSA

A very detailed study showing that RSA can be re-engineered in order to remain practical, yet it will no longer be broken by a quantum computer. The essence of the proposal is a multiple-prime RSA with great many 4096-bit primes and with 1 Terabyte public key. A significant potential weakness [for which however there is no …

Silvio Micali – A Genius Which Will Stay in the Bottle

Silvio Micali, one of the most brilliant computer scientists on this planet has just re-invented democracy or blockchains or finance or law order and public authority and few other things, with his ALGORAND system. And some other brilliant crypto innovators are also doing the same thing: see DFINITY. Possibly this is what we really want, a …

D-Day For Z.Cash

Today the first ever truly anonymous crypto currency ZEC went live. The full P2P client can be downloaded from here [Linux only for now]. The total number of ZEC coins will be only 21 million, like in bitcoin. Zerocash also reproduces few other unreasonable properties known from bitcoin: bizarre monetary policy with inelastic monetary supply and block halving every …

How Many 1024-bit Primes Have Backdoors?

So how did the NSA backdoored the Internet or did they??? New ground-breaking paper shows that DSA and DH mod P keys with 1024 bits are vulnerable to practical backdoors which can be exploited to break our secure communications. Few highlights: For such trapdoored primes the DL problem can be solved in 2 months by an academic cluster. The …
