Farcaster could end up becoming the solution to Public Key Infrastructure (PKI). To send something encrypted to someone you have to somehow agree on how they will decrypt it. Otherwise it’s pointless. Either you both have a common secret or you use something you know only they can decrypt. For the common secret how do you exchange it? Well you use a secure channel. But how do you establish that ? Enter using something only they can decrypt. No need to first establish a secure channel for secret exchange. But how to learn what only they can decrypt? In todays systems these are called public keys. That public key is a seal for your envelope with the message. The seal you know only they can open. But how to get the seal? Usually that’s either by a centralized registry (SSL certificates aka the whole internet, companies infrastructure) or by you recieving that key somehow. But how do you know it hasn’t been tampered with? Well well … 1/2

Enter Farcaster. Since Farcaster associates keys aka seals with users on a network that will reject anything that isn’t according to the rules backed by cryptography you know that any seal (key) associated with a user here is authentic. Using that you can look up all users seals on a trusted decentralized source that’s tamper proof. Now you can exchange messages and have solved the core problem of how to exchange keys. Why not use a blockchain directly without Farcaster? How do you know the wallet address of the person you send to? How to look that up? On farcaster you can use their social identity aka their username and look it up. It’s way easier to look up names especially since the social network shows you how many people you trust follow them and are connected. The social proof adds to the security of the underlying network. Yes Farcaster can be way more then a social network. No it’s not just a crypto thing, but we have to make it so. - Samuel 🦅
