Simulated Brains, Smart-contracts and the direction of time
Posted by SDLerner in Uncategorized on March 30, 2015
There are three fantastic discoveries in computer science that fascinate me: fully-homomorphic encryption , Indistinguishability Obfuscation, and sz-Snarks. Using these constructions, it’s possible to create an obfuscated program and allow others to execute the program in a way that the when the program produces an output, people cannot learn anything about its inner workings. The […]
July 2009 Mystery Solved
Posted by SDLerner in Uncategorized on June 23, 2014
A year ago I analyzed a mining pattern that suggested a correlation between Satoshi computer and another computer mining at the same time. This relation had been highlighted to me by a another user in the forums (I don’t remember who) . From this correlation I conjectured that the same computer was mining both patterns […]
Even faster block-chains with DECOR protocol
Posted by SDLerner in Uncategorized on May 2, 2014
One of the most interesting papers ever written about the Bitcoin block-chain design is “Accelerating Bitcoin’s Transaction Processing” by Sompolinsky and Zohar. The paper presents the GHOST protocol which aims to achieve higher TPS securely by changing the way nodes decide which is the best chain fork. The authors try to reduce the block rate […]
Reawaken interest in Chain-Archeology
Posted by SDLerner in Uncategorized on April 3, 2014
These days I saw some reawaken interest in searching for patterns in early mined blocks by Taras. Well, last month media circus around Dorian Satoshi may have contributed. I welcome Taras to the chain-archeology field, and I hope he does it responsibly. While reading his posts I remembered two chain-archeology techniques [1] that I planned […]
P2PTradeX revisted
Posted by SDLerner in Uncategorized on December 11, 2013
I came up with an attack on my P2PTradeX protocol, which, in most cases, would thwart severely its utility. Let’s first review the protocol. A first party issues a conditional transaction in a block chain X, which contains a contract. The contract requests the the other party to provide a proof that a payment has […]
A new mystery about Satoshi hidden in the Bitcoin block-chain
Posted by SDLerner in Uncategorized on September 3, 2013
Some time ago, I received an e-mail from my friend Timo Hanke. If you don’t know Timo, then you should, because he is, apart from a respected mathematician and Bitcoin enthusiast, an excellent person. The e-mail suggested that I looked into the nonce field to see if I could find out the endianess of Satoshi’s […]
