“Copay is an open-source multi-signature wallet with some highly interesting features created on BitPay’s Bitcore, an open source bitcoin stack. For starters, BitPay is using Copay as one of its platforms for a decentralized key generator it has developed. This way, Gallippi says if a company were ever compromised, the keys would not be as they wouldn’t come from that centralized place. Decentralized key generators add a whole new level of security the Bitcoin community needs to ensure investor confidence. According to Gallippi, he researched the top 100 richest accounts in Bitcoin and found that none of them, not a single one, was secured with multi-signature technology.”
