Right here’s a statistic that tends to be missed, in response to dYdX founder Antonio Julio: Derivatives at present make up round 75% of all buying and selling quantity within the crypto market.
Deriving worth from an underlying asset — relatively than spot buying and selling the asset itself — permits for a broader number of monetary mechanisms, similar to leverage buying and selling and futures. It additionally occurs to create a lot larger technical calls for on platforms that aspire to offer the service on the excessive quantity and velocity that shoppers demand.
However excessive quantity and excessive velocity are two fascinating traits that hardly ever discover themselves overlapping in the identical Venn diagram as blockchain tech.
On the Lightspeed podcast (Spotify/Apple), Julio explains how dYdX, the perpetual contract market, is attempting to deal with efficiency calls for by constructing its personal customized blockchain, primarily based on Cosmos SDK know-how. “It’s tailored for derivatives buying and selling, tailored for what we’re doing and we’re very enthusiastic about it,” he says.
Julio notes the transition to Cosmos is scheduled to happen this month, at which period the platform will likely be “totally decentralized.”
“Proper now, dYdX is hybrid-decentralized,” he says. “It’s totally non-custodial. It’s totally clear with what occurs on-chain. However the principle factor that’s not decentralized proper now could be the order e-book and matching engine.”
Most decentralized exchanges, similar to Uniswap and Curve, are automated market makers or AMMs, Julio says. It’s a lot easier, he continues, to function an AMM than an order e-book, which requires “far more efficiency when it comes to transactions per second, low fuel charges, et cetera.”

The rationale order books demand such excessive quantity and velocity is that 1000’s of programmatically positioned orders can happen each second, whether or not they’re stuffed or not. “No blockchain can help that,” Julio insists. “StarkWare and all the remainder of the [layer-2s] can’t come near the quantity of efficiency that’s wanted for that.”
“Probably that may change long run,” Julio provides, “and we’re nonetheless excited to see that occur, hopefully, however that’s not the case proper now.”
Decentralizing the order e-book
DYdX goals to unravel the velocity barrier by permitting purchase and promote gives to happen off-chain. All settlements the place trades are accomplished occur on-chain, Julio provides, “or at the least by means of the StarkWare rollup that we’re utilizing.”
“The principle factor that we’re decentralizing is the order e-book and the matching engine,” Julio continues. “And that’s really fairly a tough drawback as a result of these methods require actually excessive throughput.”
“We took a go searching and requested ourselves, okay, which blockchain can help on the order of a thousand plus transactions per second, ideally with very low or no fuel charges.”
“The reply we got here again with was none of them.”
The end result was to construct a “decentralized, however off-chain order e-book and matching system,” Julio says. Taking the idea of the Ethereum mempool, the place transactions wait to be mined, Julio says “what if we had the whole order e-book not need to be put on-chain?”
“The validators can hold the whole state of the order e-book of their respective reminiscences,” he says, thus furthering decentralization. “However you don’t even have so as to add something to the consensus state of the chain till a commerce occurs.”
It’s a singular property of the system, Julio says. “Solely about one % of the orders that get positioned on any order book-based trade get stuffed,” so the system requires “100x the scalability for putting and canceling orders.” The small share of trades that really happen are settled on-chain, he says.
“It made this Cosmos chain that we’re constructing a very pure match,” he says, “simply because you are able to do actually customized stuff when you personal the whole stack.”
