Shinobi’s Strawman is a weekly sequence the place our Technical Editor Shinobi challenges the Bitcoin group, aiming to fire up dialog round heated technical debates.
______________________________________________________________
We’re going to strive one thing of an experiment right now.
Drivechains are being proclaimed by some because the savior of Bitcoin, the reply to all of its issues. It solves the long run safety funds, permits full freedom to include new options into Bitcoin, and presents no downsides for current Bitcoin customers.
Sounds too good to be true? It’s:
1) Drivechains Change Miner IncentivesDrivechains introduce a hodgepodge of latest variables into miners’ incentives, and after introducing that instability advocates push for customers merely adopting a degraded safety mannequin for all new use circumstances and performance through the use of a sidechain in lieu of fixing the bottom layer. How is that this any completely different than an outright assault on Bitcoin self custody?
2) Present Sidechains Have No AdoptionThere have been many alternative design proposals for sidechains through the years, however the one at present deployed ones are run by federations (Liquid and RSK), each of which have failed to achieve any significant degree of adoption since they have been deployed. Does this imply sidechains aren’t value continued improvement effort? Or are they value it, and the failure of federated chains to be adopted is just the results of shortcomings in that particular sidechain design?
3) Drivechains Exacerbate The Dangers Of MEV
MEV is one thing that’s potential on Bitcoin already, as methods like Stacks are demonstrating, however at present the types of MEV potential on Bitcoin are both generated by completely unbiased altcoins like Stacks (which traditionally have trended to an insignificant share of miners’ earnings, like Namecoin), or very low within the degree of complexity (like frontrunning Inscriptions). Drivechains open the door to arbitrarily advanced types of MEV on sidechains, whereas additionally guaranteeing that the token producing that MEV is pegged to the value of Bitcoin. I.e. it can not merely fade away to an irrelevant fraction of miner earnings as individuals cease shopping for an altcoin. This drastically worsens the dangers and potential injury of MEV on Bitcoin.
4) No, Swap Markets Aren’t An AnswerPaul Sztorc replied to a few of these considerations on Twitter, however these responses do probably not handle the basis points. Swap markets may sound like a solution, however the actuality is that these simply shove the liquidity necessities onto one more get together, assuming they may present huge quantities of liquidity for nearly nothing in return. That may work for small scale utility customers, or having liquidity out there to arbitrage uncertainty across the peg, I don’t assume it is a foregone conclusion that sufficient liquidity to cowl the “resolution to the safety funds downside” with out slippage is a given, to say nothing of all the opposite customers who would need to swap out and in. He then goes on to disregard the distinction between a mainchain reorg, which requires redoing work and power expenditure, versus a sidechain reorg which doesn’t. Lastly, he equates a random individual for no logical or revenue pushed purpose giving cash away with somebody producing a revenue with an exercise they’re the only gatekeepers of.
Look, finally, I’m a Bitcoin maximalist. I need what’s finest for Bitcoin.
I believe drivechains are silly, harmful and a waste of time, however I need to hear your ideas on the topic. Am I fallacious concerning the factors above? Is there one more reason that I needs to be in opposition to drivechains that I’ve neglected?
Please don’t write to me with some random hopium. I’m open to novel opinions. I need the dialog to progress. Above is my finest summation – we merely aren’t wherever near a significant consensus on drivechains.
My DMs are open. Opinion@bitcoinmagazine.com. Let’s hash it out.
