Crypto and Consent

One of the most exciting things about cryptocurrency is that the future hasn’t been written yet. And one of the things that strongly distinguish people in the cryptocurrency movement is how they deal with consent. If you care about consent, the safest thing to do is to ask every time. We are all creating this movement together. Let’s all do our best to build the culture of consent. The future of cryptocurrency, the future of open source money, and therefore the future of our financial infrastructure depends on it.

The Two Cardinal Rules of Cryptocurrency

There are only two cardinal rules of cryptocurrency that arise directly from public key cryptography. As you probably know, modern cryptography is based on paired keys, a public key and a private key. Because of the blockchain, public keys and incidentally wallet addresses should be verified before sending. Due to the principle of immutability and the lack of a trusted intermediary, there’s no way to contest or reverse a transaction once it’s been made.The second law is simply that the owner of the private key is the owner of the wallet and all the funds therein.
