tldr; Channels are just FIDs with USER_DATA_IS_CHANNEL=true

Description

For this proposal:

A channel is a curated feed of casts.
A channel is identified by an FID, let's call it channelfid and the corresponding fname, @channelfname.
When a user wants to post to a channel, they just mention @channelfname.

This is a proposal that introduces ordering to the Farcaster protocol. (See farcasterxyz/protocol#193)

The main advantage of this proposal is that it does not require any coordination (for example no need to appoint special roles or powers to a specific serializer).

High level architecture

There is a mempool where every hub submits deltas. Miners propose new blocks, each block is linked to the previous one in a blockchain. Anyone can spin up a miner.

Miners have to stake (lock) an amount of ETH but this amount is not fixed and may go up automatically if many miners compete in block creation. The stake is not slashed or lost in any way, but it will remain locked for 100 days, before the miner can withdraw it.

Proposal: Farcaster Frame-Domain association

Goals

Create an association between a Frame domain or URL and an fid that can be lazily verified.
Minimize number of tools and network requests required to verify a domain association.
Allow for future extensions to domain verification.

Proposal (no protocol change)

The idea is to provide a way for an FID to publicly declare that they trust a URL. The simplest way to achieve this is

Goals

Enable the creation of frames that are statically hosted (accessible using HTTP GET vs HTTP POST).
Keep it as simple as possible.

Proposal

Add a new fc:frame:button:$idx:action type, get. Modify the use of fc:frame:button:$idx:target prop.

Mathematics: What do grad students in math do all day?

by Yasha Berchenko-Kogan

A lot of math grad school is reading books and papers and trying to understand what's going on. The difficulty is that reading math is not like reading a mystery thriller, and it's not even like reading a history book or a New York Times article.

The main issue is that, by the time you get to the frontiers of math, the words to describe the concepts don't really exist yet. Communicating these ideas is a bit like trying to explain a vacuum cleaner to someone who has never seen one, except you're only allowed to use words that are four letters long or shorter.
