Could miners run a modified version of the software to choose not to publish a transaction in the blockchain? I just checked both RSS feeds, and they seem to be fine. On the first point, many people reuse addresses, so in practice public keys are often widely known. At present this all seems to be working okay, but over the long run I suspect will limit the use of Bitcoin for small transactions. Proof of Stake Protocols and Validators panel. The puzzle David has to solve — the proof-of-work — is to find a nonce such that when we append to and hash the combination the output hash begins with a long run of zeroes. These de-anonymization techniques are well known to computer scientists, and, one presumes, therefore to the NSA. The nature of asymmetric cryptographic digital signatures is that I can sign any piece of data using my private key, and anyone else with only my public key can verify that the person who signed that data holds the private key.

From my personal experience, the initial sync actually took over five days to complete on a 2. Amit Prakash permalink. If that variance is reduced too much, then it creates an interesting attack possibility. Besmir permalink. So it seems reasonable that most client software would use a random sequence of nonce guesses rather than guessing sequentially from 0. Does everyone have their own version of it or do they sync to a master? So there is most likely only a brief period of time in which Alice can double spend. On the first point, many people reuse addresses, so in practice public keys are often widely known.
Is it not possible for two miners to be working on different blocks which contain mostly, although not all, the same transactions?
