As blockchain ecosystems mature, the velocity and effectivity of the infrastructure for nodes have turn out to be extra than simply technical concerns —they’re strategic imperatives. Main the cost on this area is Austin Federa, former Head of Technique on the Solana Basis, who’s gearing as much as launch DoubleZero, a protocol designed to redefine how blockchains talk and scale.
In a wide-ranging dialog with CoinDesk, Federa delved into the motivations behind DoubleZero, the challenges it addresses and which will come out of it, and why its imaginative and prescient for a high-performance networking layer may very well be the inspiration for the following era of decentralized methods.
DoubleZero was first introduced in December 2024 as a blockchain layer aimed to be quicker than the web and subsequently essential for crypto trades. Since then practically 12.57% of SOL staked is working on the DoubleZero testnet. The mainnet launch is anticipated to occur someday in September.
This interview has been edited for brevity and readability.
CoinDesk: Clarify how DoubleZero works to somebody who’s new to crypto.
Austin Federa: I believe one of many best methods to clarify what we’re constructing is we’re constructing crypto’s model of Flash Boys.
That actually was this transformational second the place folks type of realized that your edge in execution on a centralized buying and selling venue, was now not your precise commerce logic or the velocity of the pc that you’ve got hooked as much as the market, it’s how shortly you will get information between totally different factors the place market occasions happen. That was type of a very huge change within the trade, as a result of transit time was not [previously] thought of to be terribly vital.
You may return and watch Formulation 1 races from the 80s, they’re simply taking a cigarette break throughout a pit cease, after which somebody realized “oh man, we’re really leaving numerous time on the observe by these pit stops not being optimized.” And it truly is one thing fairly related within the buying and selling area.
So for crypto, the thought of utilizing one thing that is quicker than the general public web (that you need to use a community that you need to use applied sciences on that aren’t obtainable on the general public web), it is not essentially a brand new concept. The issue was, till DoubleZero got here alongside, it must have been run by one centralized firm and never enable for a number of unbiased contributors.
The primary know-how, philosophy and financial unlock of the DoubleZero protocol is that it permits a number of contributors which have their very own fiber networks to contribute parts or all of that fiber community to the DoubleZero community. It builds a large, extraordinarily excessive efficiency fiber mesh community that connects folks all all over the world.
CoinDesk: Why construct for Solana?
Federa: We’re not really constructed on Solana. We do have a separate ledger system, but it surely’s not a community that anybody ever deploys a wise contract to, it truly is simply an accounting database.
The rationale that we’re supporting Solana first…is as a result of Solana is fairly distinctive. In the event you have a look at quick blockchains, and you then have a look at node rely, there is a ratio of transactions per second to variety of nodes, nobody comes even near Solana.
Any community that’s wherever close to the efficiency of Solana has a 1/fifth to a 1/tenth of the variety of precise nodes. And so the communications downside is an exponential downside. The extra nodes you could have within the system, and the extra locations that you must get information to go, the extra bandwidth you want, the extra the communication turns into a bottleneck.
So the larger and the quicker you get a blockchain community, the extra communication turns into a bottleneck for that community transferring shortly. And so the actual aim behind what we’re doing is to permit blockchains to go quicker than the general public web, with out having to drop node rely or add centralization.
We expect DoubleZero has much more purposes than simply Solana, and much more purposes than simply blockchain. However it’s the place the place there’s the most important want in the intervening time. You have a look at the opposite blockchains on the market, and so they simply haven’t got these issues but.
CoinDesk: How does staking on Solana tie to DoubleZero?
Federa: We now have a stake pool that’s staking to nodes on DoubleZero. As a share of stake, it is fairly small, it is about 3 million SOL, (there’s 500 million SOL), so it is not an enormous quantity of SOL. That was initially conceived of as a manner to assist subsidize the price of validators working on our testnet, however turned out folks have been simply very serious about working on testnet, and in order that’s been a very nice software for getting extra folks on board with the community.
After we launch mainnet information in September, that is going to be over 50 totally different fiber hyperlinks proper now. Presently its at eight. Most of the hyperlinks might be 10 instances quicker than the connections that we have now at present when it comes to their capability. So going from 10 gigabit to 200 gigabit connections.
We see a future the place, if you get sufficient stake working on the DoubleZero community, protocol designers at Solana at the moment are in a position to jack up limits manner greater than they’ll on the general public web, as a result of there’s extra capability provided on DoubleZero than is obtainable to validators working on the general public web at present, and it is a decrease latency connection. So the info transmission really, not solely are you able to ship extra information, however that information arrives extra shortly than it will in any other case.
CoinDesk: So in your world there are two eventualities right here: you could have the general public web, or you could have one thing like a DoubleZero. If you wish to get one thing finished quicker, faster, or different advantages in your commerce, you go the DoubleZero route. Does that then create a efficiency inequality between validators on Solana?
Federa: We get a model of this [question] so much. And the query to ask your self is, is the web a centralizing drive? The web is principally simply 20 firms which have many of the connectivity. And at present if the entire OECD nations all of a sudden mentioned, “no extra crypto,” principally all the things however bitcoin is hosed.
So after we’re trustworthy about what we’re feeling about right here, the significance is to not eliminate the web solely. It’s to verify the web is there as a fallback, as a censorship resistance path. And so if DoubleZero is offline, or if there’s a unhealthy actor within the DoubleZero community that decides to try to censor blocks or one thing together with censored information transferring by way of it, two issues will occur:
One, that is why we have now 9 unbiased contributors on the community, so information will simply route round them, and we are able to principally kick a contributor off the community. And the second factor is, we all the time have the general public web to fall again on. Now which will require Solana dropping from 500,000 transactions per second to 10,000 transactions per second. However that is not a foul failback state.
That is type of your traditional, “there is a visitors jam on the freeway, I will take the county highway in the intervening time.”
CoinDesk: So mainnet is coming very quickly. What’s taking place between at times?
Federa: It is numerous testing, it is numerous ensuring that we’re absolutely able to go. After which it is clearly a token-based venture. So there’s a token launch that may associate with that as properly, additionally within the month of September.
