Six Confirmations Aren’t Really Needed for Bitcoin Transactions ?

Interesting read…

“In a recent research paper, European mathematicians Cyril Grunspan and Ricardo Pérez-Marco demonstrated through calculus and game theory that, thanks to the robust network security and relatively high BTC price, small bitcoin transactions may not need the six confirmations typically required by merchants and exchanges.

Published on the computer science and cryptography section of Cornell University’s arXiv library, the paper takes on the calculations of Satoshi Nakamoto, as presented in subchapter 11 of the Bitcoin white paper.

‘Our new paper combines two main previous results,’ Pérez-Marco told Bitcoin Magazine. ‘The first one is the exact computation of the probability of success [of a double spend attack] (‘Double spend races,” 2017) and the second one takes into account the exact model for profitability that we developed for analyzing selfish mining strategies (“On profitability of selfish mining,” 2018).’

In a nutshell, this new research paper asks: ‘How profitable is it to double-spend a transaction and how many network confirmations are really enough to financially incentivise honest mining?’”
