to BAM or not to BAM? 🤔💀
here's the:
✅Good
apps control Tx order (ACE) makes Solana DEXs competitive (tighter spreads)
❌BAD
validators accept Tx *ONLY* from BAM
no longer accept Tx from Solana network
👹Ugly
Jito gatekeep ACE "plugins"
1/6
✅Good - ACE is super valuable!
Solana must compete with single-sequencers, e.g. HL which put makers Tx before takers.
Some (@trentdotsol, Michael from FD) think "increasing tps solves this" but I'm with @MaxResnick1 - Solana must compete TODAY.
/2
❌BAD - for BAM to work ALL Tx must go thru it
validators will stop including Tx they see directly from the Solana network
BAM decides the order & sends Tx in-order to be executed by the validator.
so why do we even need decentralized validators?🤷♂️
rubberstamps ftw! /s
/3
👹Ugly - Jito needs to gatekeep plugins
if they don't
- searcher adds plugin that puts his Tx first
- all BAM nodes run it
this means new apps cannot quietly & permissionlessly experiment - they need Jito to let them
/4
can we do better? YES
- leader decides ordering
- apps permissionless create prio-accounts
(eg jup_prio1_xxx, jup_prio2_xxx)
- protocol revert Tx w/o right read-lock right prio-account
why validators follow this order?
*apps* pool user fees, pay validators, ban rouges
/5
is there nuance here?
you bet!
but my 3 main takeaways are:
1️⃣ ACE is super valuable
2️⃣ strong disagree Solana should outsource *ALL* Tx ordering to another protocol
3️⃣ Solana can achieve ACE w/o this "outsourcing"
and we're building it 😎
6/6
@KultureElectric @jito_sol @buffalu__ @brian_smith_0 btw - not sure why @michaelh_laine is totally ok with this strategy
he gave me hell for Paladin GH being invite-only initially
I expect him to hold Jito to the same standard (BAM decides *all* Tx included by leaders, Paladin just slightly affected it)
