Title: Mathematics of generating an alternate chain (Bitcoin whitepaper). Post by: tobasco on October 23, 2019, 04:13:56 PM I've been looking at the equations from the bitcoin whitepaper. It gives the following probabilities of "catching up" from z blocks behind (with my 0.1 probability of mining a block) as follows:
Code: q=0.1 However, if I want to replace the top block in the chain, catching up isn't going to be enough as I need to build a longer chain for other nodes to adopt. So would it by correct to say my probability of replacing the top block in the chain would be: Code: z=2 P=0.0509779 Because I need to build a chain one block longer than the number of blocks I need to catch up with. Is that correct? |
