FIP: Snapchain A new proposal to introduce global ordering to Farcaster hubs. We'll discuss this in more detail in the dev call tomorrow, but sharing an early draft for feedback. https://warpcast.notion.site/Snapchain-Public-0e6b7e51faf74be1846803cb74493886

@aviationdoctor.eth

Couple of questions, please: 1/ if Alice casts, will she and everyone else have to wait ~7.5 seconds on average for the next snap for her cast to be visible, including in her own local client (not sure if a client shows the local “mempool” in addition to the hub’s contents)? Could this introduce some conversational lag that wasn’t there before? 2/ if Alice posts and deletes her cast immediately, does the snap pruning mechanism mean that nothing gets written to the hubs (I’m unclear about the example provided in the doc)?

| Per-cast fees are a really bad user experience haven’t thought through this deeply, but couldn’t you just mentally model the current Storage implementation as a “preloaded balance” for casts?

1. The geographic placement and operation of 10-20 write hubs (or whatever the number may be) feels very hard to get right. Some concerns there about restrictiveness of any governance approach. 2. FID based sharding starts to sound a lot like ATProto PDS, yeah?

will write hubs be permissioned? if so, any thoughts around ho to decentralize this? thought: i remember the steemit blockchain (2017) required $STEEM in yr wallet in order to write to the chain (so not unlike paying a fee for an FID/storage), and you were rate limited based on amount of steem you had (no gas fees per post) -- there were a lot of interesting ideas there, and also a lot of problems that i forgot about now.

This seems super centralized seems you can just censor the write of the ‘official hub’; it’s even worth than Fediverse from that perspective.

Thanks for the direction! I'm curious to see how we can achieve a certain Goldilocks number. Personally, I think it would be good to use a scoring for eco contribution other than voting or staking. @v do you have any thoughts on maintaining an archive of pruned snapshots, or is it still the role of services?

Noob question: how many years of software engineering do you have to have under your belt to figure this out?

i think this will not make hub faster innit, parallelchain should be the term like golang concurrency
