Bitcoin’s Bizarre New Twist: ColliderVM Unleashes Sarcasm and Fortune

In a most audacious display of digital hoopla, the ever-so-elegant StarkWare and the renowned Weizmann Institute of Science have ceremoniously revealed a cunning ploy to tiptoe around Bitcoin’s script shortcomings. Naturally, they promise untold riches and endless amusement 🤔—all while making you pay for the popcorn.

Their scholarly treatise expounds upon a system so refreshingly complicated that one can scarcely imagine how many quavering minions are required to keep it afloat. But do rejoice: this scheme might allow elaborate Bitcoin smart contracts to prance about in a more “capital-efficient” manner. Delightful, is it not? They claim it’s also rather thrifty in computing terms—because who doesn’t love pinching digital pennies?

Behold: ColliderVM, an agreement of sorts that magically endows Bitcoin with multi-step processes, thus granting transactions the lucidity of a fish riding a bicycle. Since Bitcoin usually keeps its script output all hush-hush, complex calculations were previously about as possible as forcing a cat into a burlesque show. But fret not. ColliderVM bestows upon us the majesty of STARKs, ensuring that Bitcoin can verify fancy offchain computations with scarcely a thought wasted on chain data.

ColliderVM targets Bitcoin limitations

Picture four million OPCodes crammed into a block, each one pleading for life, and only 1,000 stack elements to keep them warm. Meanwhile, each script floats through the ether—utterly forgetful of prior escapades. One wonders if this is a cunning design or merely a cosmic prank. BitVM tried to fix such limitations with tricky fraud proofs, requiring operators to stash away a safety nest egg for potential fiascos. Yes, quite cheerful.

Implementation, they say, can be costly—like paying for an extended stay at a hotel with no bar. Prior contraptions demanded cryptographic one-time signatures that taxed the brain as well as the CPU. Fortunately, ColliderVM draws upon a more civilized approach from the 2024 ColliderScript paper, employing a hash collision challenge that finds malicious actors about as welcome as a bull in a teashop.

The net result? Less computational agony for honest folks, more sweaty brow moments for scoundrels. Sounds like a fair trade to us 🤷.

Hash, but no food or weed

Here enters “the hash”—adored by mathematicians, feared by those with unmentionable secrets. This cryptic function compresses arbitrary data into a tidy strand of alphanumeric nonsense, leaving no morsel for reversal. No munchies here, folks. Just a neat data ID and no possibility of retrieving the original feast.

This cunning contrivance is reminiscent of Bitcoin mining, though with fewer comedic mishaps than one might expect. ColliderVM’s virtuosos claim a dramatic reduction in operations compared to BitVM—by at least 10,000 times. Marvel at their modesty.

Ostensibly, this wizardry draws Bitcoin ever-closer to a STARKs-based sidechain that might one day trundle onto the stage with minimal fuss. Or so they’d have us believe. Their rousing literature proclaims:

“We estimate that the Bitcoin script length for STARK proof verification becomes nearly practical, allowing it to be used alongside other, pairing-based proof systems common today in applications.”

STARKs, in all their zero-knowledge glory, promise to do wonders without the usual shady rituals or “toxic waste” one-time setups. Who wouldn’t love a trustless system that doesn’t require burying radioactive data in the backyard? But alas, dear Bitcoin can’t exactly accommodate such large scripts without heroic measures. ColliderVM’s minions vow they’re inching towards practicality—one dainty step at a time 🦶.

Bitcoin-based trustless sidechains?

Bitcoin is the grand old dame of blockchains—sturdy yet somewhat limited in its stage repertoire. Sidechains, such as Liquid, exist in a cloud of mild distrust. ZK-proof-based solutions have bedazzled cryptographers for ages, all while elusive 2014 papers whispered the potential for trustless Bitcoin sidechains. And here we are, a decade on, still awaiting the comedic climax.

ColliderVM, for all its pomp, remains somewhat reliant on trust that a few well-meaning participants won’t completely bungle the system. Trust-minimized, they say, not trustless. Truly uplifting. But you can clutch your pearls if it makes you feel safer.

The study’s leading minds—Eli Ben-Sasson, Lior Goldberg, and Ben Fisch—contribute to this circus with unbridled enthusiasm. Their passion for zero-knowledge proofs seems unwavering, and in interviews, Ben-Sasson politely suggests that a genuine layer-2 solution for Bitcoin must “inherit Bitcoin’s own security.” Seems easy enough, right? Meanwhile, other solutions merrily rely on humans, signers, or your neighbor’s suspicious “honesty.”

At least there’s the Lightning Network, which scuttles about with a decent helping of Bitcoin security. So chin up—our digital realm isn’t all gloom, doom, and monstrous computational nightmares… unless you fancy that sort of thing 🤣.
