TL;DR
Full Story
Image this…
You’re touring and break your arm (not nice), so that you go to the emergency room (costly, sure — however that’s what insurance coverage is for).
You arrive and are rapidly informed the wait time is ~2hrs (very doable).
-
2hrs move…and nothing (okay, this is an emergency room in any case — they’ll get to you ultimately)
-
4hrs move (“man, they should be slammed” — you make eye contact with the nurse on the entrance desk — she smiles as if to say “I haven’t forgotten you”)
-
8hrs move (“how injured do it’s a must to be to see a health care provider round right here?”)
-
16hrs move (“Dammit, I’m about to interrupt my different arm simply so I can see somebody!”)
-
32hrs move earlier than you understand: the nurse behind the desk is taking bribes from individuals to leap the road! (Your anger knows no bounds)
That ☝️ proper there ☝️ is what’s taking place on Solana proper now.
Some Solana ‘shopper’ builders (aka the oldsters answerable for writing software program that lets people entry/transact on the Solana community) have created this stuff referred to as ‘mempools’ (aka ‘transaction ready rooms’).
And identical to the nurse within the above story, these mempool operators will leap your transaction to the entrance of the queue should you grease their palms a little bit.
The issue is:
These fee-based mempools could be manipulated to allow bot assaults.
Plus, in instances of heightened exercise on the Solana community, on a regular basis customers are having gradual and clunky experiences, trigger they preserve getting pushed to the again of the road.
(Which is a matter given Solana’s entire worth pitch is actually “we function on the pace of sunshine”)
The answer?
Axe the mempools and return to a ‘first in, finest dressed’ mannequin.
Which is strictly what Jito — the most important mempool operator on Solana — has simply carried out.
Nevertheless it ain’t an ideal resolution…
Right here’s the place it will get a little bit wack-a-mole-y
Mempools aren’t a normal function of Solana. As a substitute, they’re made and operated by third celebration builders.
The identical manner Flappy Fowl wasn’t developed by the creators of our iOS/Android working techniques — however as an alternative by a 3rd celebration developer, referred to as Dong Nguyen.
And when Dong eliminated help for Flappy Fowl, others noticed a chance and began flooding app shops w Flappy Fowl copy cats.
(The identical factor would possibly occur with mempools on Solana).
