Bitcoin, the worlds most popular cryptocurrency, has got its long-awaited upgrade, with a focus on improving the network's privacy and security. Taproot, which went live on November 14, uses an enhanced form of signatures for transactions called Schnorr. The new signatures make complicated, multi-signature transactions appear like any other transaction. This makes it difficult for snoopers or would-be hackers to trace larger transactions or unusual ones.
