This is an typically neglected statistic, based on dYdX founder Antonio Julio: Derivatives presently make up about 75% of all buying and selling quantity within the crypto market.
Deriving worth from an underlying asset – slightly than buying and selling the asset itself on the spot market – permits for a greater diversity of monetary mechanisms, akin to leveraged buying and selling and futures. It additionally occurs to position a lot larger technical calls for on platforms that attempt to ship the service on the excessive quantity and velocity that prospects demand.
However excessive quantity and excessive velocity are two fascinating traits that hardly ever overlap in the identical Venn diagram as blockchain expertise.
On the Lightspeed podcast (Spotify/Apple), Julio explains how dYdX, the perpetual contract market, is attempting to satisfy efficiency necessities by constructing its personal customized blockchain based mostly on Cosmos SDK expertise. “It is tailored for derivatives buying and selling, tailored for what we do and we’re very enthusiastic about it,” he says.
Julio notes that the transition to Cosmos will happen this month, after which the platform might be “utterly decentralized.”
“Proper now, dYdX is hybrid-decentralized,” he says. “It is utterly non-custodial. It’s utterly clear about what occurs within the chain. However an important factor that’s not decentralized in the mean time is the order ebook and the matching engine.”
Most decentralized exchanges, akin to Uniswap and Curve, are automated market makers, or AMMs, Julio says. It’s a lot simpler, he continues, to function an AMM than an order ebook, which requires “rather more efficiency by way of transactions per second, low gasoline charges, and so forth.”

The rationale order books require 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 emphasizes. “StarkWare and the remainder of the [layer-2s] I can not get near the quantity of efficiency it takes.”
“Presumably that can change in the long run,” Julio provides, “and we’re nonetheless excited to see that occur, hopefully, however that is not the case proper now.”
Decentralization of the order ebook
DYdX goals to resolve the velocity barrier by permitting shopping for and promoting provides to happen outdoors the chain. All settlements the place transactions are accomplished are carried out on-chain, Julio provides, “or at the least by means of the StarkWare mixture we use.”
“Crucial factor we decentralize is the order ebook and the matching engine,” continues Julio. “And that’s really fairly a tough downside, as a result of these techniques require a really excessive throughput.”
“We appeared round and requested ourselves: OK, what blockchain can help on the order of properly over a thousand transactions per second, ideally with very low or no gasoline prices.”
“The reply we got here again with was neither.”
The end result was constructing a “decentralized, however off-chain order ebook and matching system,” says Julio. Based mostly on the idea of the Ethereum mempool, the place transactions wait to be mined, Julio says, “What if we did not should put your complete order ebook on-chain?”
“The validators can preserve your complete standing of the order ebook of their respective reminiscences,” he says, selling decentralization. “However you do not even have so as to add something to the consensus state of the chain till a transaction happens.”
It’s a distinctive characteristic of the system, says Julio. “Solely about one p.c of orders positioned on an order book-based alternate are stuffed,” so the system requires “100x the scalability for putting and canceling orders.” The small share of transactions that really happen are dealt with on-chain, he says.
“It made this Cosmos chain that we’re constructing very pure,” he says, “simply because you are able to do actually customized issues if you happen to personal the entire stack.”
