Threshold Signatures: The New Standard for Wallet Security?
A group of researchers from Princeton University, Stanford University and the City University of New York, have announced a new ECDSA threshold signature scheme that is particularly well-suited for securing Bitcoin wallets. Threshold signatures can be thought of as "stealth multi-signatures." The new Bitcoin security scheme is detailed in a research....

In particular, ROAST has been posited as a signature standard that could work with, and improve, threshold signature schemes such as FROST (Flexible Round-Optimized Schnorr Threshold Signatures). The research unit of Bitcoin (BTC)-focused blockchain tech firm Blockstream has published a proposal for a new type of multisig standard called Robust Asynchronous Schnorr Threshold Signatures (ROAST). It hopes to avoid the problem of transaction failures due to absent or even malicious signers and can work at scale. The term multisig or multisignature, refers to a method of transaction in which....
Bitcoin solutions developerAirbitz has developed a mobile wallet that now supports deterministic transaction signatures. The transaction signatures support the RFC 6979 standard. To understand why this is significant, here is some background on signatures and why they are necessary. Bitcoin uses elliptic curve digital signatures which require a random value with every transaction. Multiple transactions utilizing the same private key and a poor random number generator for transaction signing may reveal a significant portion of the private key. Digital Signatures Explained. In an open source....

Times have been busy in the bitcoin wallet world lately. Two hardware wallets - Trezor and BTChip - have finally shipped, and wallet security continues to mature. In spite of all this, though, people who should know better are still being robbed because they fail to add more protection to their bitcoin holdings. To tackle the issue of bitcoin wallet vulnerabilities, it's important to look at the security protections that are currently available for wallets, and to explore what work still needs to be done in the future. Multisig. 2014 was to be the year of multiple signatures (multisig),....
