Over the public internet that handshake does real cryptographic work: the caller sends its public key in a <code>SW-Public</code> header, a one-time <code>SW-Nonce</code>, and a secp256k1 <strong>signature</strong> proving it holds the private key for that public key. Forge the header and you fail the signature check. That is the whole point.</p>https://blog.theskywirenetwork.net/posts/skycoin-security-for-next-generation-cryptocurrency/Wed, 13 Dec 2017 00:00:00 +0000https://blog.theskywirenetwork.net/posts/skycoin-security-for-next-generation-cryptocurrency/<p>In 2011, the Skycoin team launched a major research project to correct flaws inherent in Bitcoin. We redesigned Bitcoin from the ground up to create a next-generation cryptocurrency that was faster, more usable, and more secure than any previous coin. The result is Skycoin: the next step in cryptocurrency evolution.</p> <p>Skycoin’s design philosophy is built on the idea that a simple, usable system provides the best security for its users. By creating a decentralized network that’s optimized for usability, Skycoin protects against attack and encourages transparency. Skycoin introduces a new cryptographic primitive called a public broadcast channel. It also uses Obelisk, a novel consensus algorithm implementation that solves issues arising from Bitcoin’s Proof-of-Work and mining processes. Skycoin security features include:</p>
