The latest news and insights about Cryptocurrency Wallets.
A cryptocurrency wallet is a device, physical medium, software program or service that stores and protects public and/or private keys and can be used to receive or send payments.
The March 8, 2021 announcement that PayPal agreed to acquire Curv was met by many in the industry with excitement, but for others concern. After all, it’s common for such acquisitions to lead to fundamental changes that require a new direction for the customers of the company being acquired. While change is never easy it also opens the door to new opportunities to select new solutions from the perspective of experience and insight on changing market requirements. As the original pioneer and industry leader in MPC and Threshold Cryptography (TC) schemes Sepior is helping many companies through this transition and stands ready to assist others.
Ethereum transaction fees have hit new highs in 2021. One of the factors is that the price of Ethereum has also hit new highs, but there’s much more to it. One way to minimize transaction fees is to use secure Multiparty Computation (MPC) for your multiple party approved transactions. In addition to minimizing the cost of your own transactions, you’ll maximize Ethereum’s throughput and contribute to reducing fees for everyone.
In 2008, the same year that Satoshi Nakamoto published the famous Bitcoin white paper, a group of cryptography researchers in Denmark implemented the first production deployment of a technique known as Multiparty Computation (MPC). It was not obvious at that time, but MPC would ultimately become the basis for Crypto Wallets 2.0, ushering in an era of increased security for institutional- and consumer-grade wallets, with native support for any digital asset.
HD wallets are a feature of bitcoin and similar cryptocurrencies with the goal of providing improved privacy and usability. Compelling benefits can be achieved when using non-hardened key derivation. The problem is that if the private key corresponding to an xPub address is somehow leaked, then the private keys of *all* “siblings” and the parent can be exfiltrated. Multi-party computation offers a way to improve this state of affairs because a private key is never in one place (even when signing).
