  • Okamoto Beats Schnorr: On the Provable Security of Multi-Signatures

    The insecurity discussion starts near the bottom of page 2 of the paper The security issues the paper discusses are pretty simple to solve theoretically, but they all increase the communication complexity of the signing schemes from O(n^2) to O(n^3) Which means there’s that many more points at which the multisig can be sabotaged or an error of some sort can occur Which basically means that all of those schemes are useless for large numbers of participants Not that they were that useful for any significant number of participants with a complexity of O(n^2)

  • r/Bitcoin - The weird nonce pattern

  • Taproot, and Schnorr, and SIGHASH_NOINPUT, oh my! - Pieter Wuille, Bitcoin Core developer and Blockstream co-founder, spoke about Taproot, Schnorr, and SIGHASH_NOINPUT.

    In this talk Pieter went into the benefits of these ideas and discussed an upcoming proposal for a first step that combines a subset of these ideas. Some ideas will be left for future extensions, in order to avoid complexity and limiting the design space. Yet, this would bring privacy and flexibility benefits to Bitcoin, as well as moderate scaling advantages. The main focus is Taproot, which has the potential to make all outputs look identical, by merging pay-to-pubkey and pay-to-scripthash into one - but other changes will be needed to make it widely applicable and efficient.”

  • To everyone rushing back into BTC from altcoins: What matters is that you learn why Bitcoin needs to be conservative in its development.

    Over the past year, the prevailing thought among many in the cryptocurrency communities is that bitcoin is not keeping up with other coins. That somehow bitcoin was being intentionally crippled, or that the developers did not know what they were doing. As we are seeing with the bitcoin dominance going up, that prevailing thought was wrong. The coins who were supposedly going to kill bitcoin have been all but abandoned in many cases. Many others are in the process of dying a slow death (which may take years to fully play out).

  • The Blockchain Backbone Model

    Today I gave a talk about the Bitcoin Backbone model, the first mathematical theory to prove bitcoin is secure, invented by @sol3gga, Nikos Leonardos and Juan Garay. [*]

What Is a BIP? - The Most Famous Bitcoin Improvement Proposals - C…

There are some that argue that these BIPs can and will eventually lead to more forks in the network which is generally considered to be a bag thing in the cryptocurrency community at large.
