I'm so thrilled to be talking about

Space and Time today. My name is Scott

Dystra, co-founder, CTO of Space and

Time. We were born within the Chainlink

ecosystem. We were essentially incubated

within Chainlink and uh we we've built

the the data blockchain, the first ZK

proven tamperproof database for the EVM.

And we're so thrilled to be partnering

with Chainlink as a Chainlink build

partner. I believe the second chain link

build partner that started all the way

back in early 2022. This is now our

fourth SmartCon. So we did Barcelona, we

did Hong Kong and it's it's really nice

to to be back in New York. We were in

New York I guess 3 four years ago. Um

everyone asks what is space and time?

What are how do you provide data to

smart contracts? Isn't that what chain

link does? The answer is yes. Of course

that is what chain link does and we're a

complimenting solution. Let's quickly

journey back through Oh. Oh, yeah. We're

good. Quickly journey back through kind

of the milestones of space and time. We

worked with Microsoft in early 2022 uh

to kind of with backing from Microsoft

as as Microsoft M12 ventures kind of

only crypto investment. They were

starting to get into into blockchain and

wanted to partner with strong ecosystem

projects.

We also partnered with chainlink in 2022

to kind of begin building space and time

as a as a sister solution or as a

incubated solution within chain link. In

2023, we released an indexing product so

that everyone could get accurate

institutionalgrade blockchain data from

the EVM from a lot of EVM chains as well

as non EVM like Bitcoin and SUI. And we

onboarded about 100 customers to the

space and time data set. In 2024, we

launched SPA uh test net and we open

sourced all of our ZK research. We

invented and patented the first ZK proof

for SQL. What that means is we can

cryptographically prove that a SQL query

in a database is accurate so that smart

contracts can actually query data for

the first time. And I'll be talking

about that in a lot more detail. And

then finally this year we launched

mainet of space and time. You could

think of space and time as 20 nodes

sitting offchain listening for requests

from Ethereum and Bass and Hyperlid in

every popular EVM. We got about 150,000

users today across the ecosystem. Mostly

devs building and vibe coding on top of

space and time using our data as well as

some smart contract engineers that are

building DeFi protocols and most

importantly a few major institutions

like US Bank that are using space and

time to begin securing their off-chain

data which I'll talk about in a lot more

detail as well. So what does this mean?

right now all these institutions I I'll

say this the word institution a lot this

presentation because chain link has

really pioneered this like chain link

started harping about this in 2020 to a

point where everyone was almost like we

get it chain link yes institutions are

coming sure like there's going to be

some banks that use blockchain but chain

link kept saying it and they kept

sticking to it and they kept building

the right infrastructure and here we are

now in 2025 and there's a lot of folks

in this room are actually have have a

name tag on that is from a bank. And so

we listened to chain link in 2021 and

2022. So when we set out to build space

and time, we realized that these

financial institutions don't really have

a way to ask questions about their

onchain and off-chain assets, especially

historical questions from a smart

contract. So if you're if you have T

bills, treasury bills in a traditional

account or equities or you know any

money market assets, you have a balance

in a traditional off-chain account.

What that really is is a row in a

traditional database in a transactional

database like Oracle, not to be confused

with chain link oracles. I'm talking

about Oracle, the database company.

all these accounts from, you know, uh,

T- Bill reserves to Tesla equities to

bonds, money markets, you name it,

right?

There's no way for these institutions to

get that data out of those source

databases and connect it to a smart

contract in order to mint stable coins,

RWA, etc. without an oracle like

Chainlink. And Chainley does an

incredible job of grabbing that source

data and coming to consensus and

delivering it to a smart contract

quickly in the current state. Meaning

what's happening right now? What's my

current balance of treasury bills that I

want to that you know that I'm eligible

to mint new stables on chain? What's my

current balance of Tesla stock of Tesla

equities in this portfolio that I can

then connect to a smart contract to mint

a one for one equities to new tokenized

asset ratio

and chain link helps solve that problem.

But what happens when I want to go

beyond just a simple data point of like

what's the current state be what's the

current price of Tesla the current

balance of my portfolio and you want to

ask historical questions like hey if

over a 7-day period uh you know this um

if over a 7-day period we meant more

than x amount do xyz or hey if the total

market cap of this stable coin reaches a

certain amount in a in a 24-h hour

period uh you know uh burn some that

kind of logic requires is looking back

on chain an hour, 24 hours, 7 days,

sometimes 30 days for rewarding

validators. We have teams that come to

us and say, "Hey, we want to look back

30 days on chain and give rewards to

node operators for what they did over

the last 30 days." So all these kind of

use cases around balance sheets from a

traditional database getting sent to the

to the blockchain for minting is can be

uh facilitated by chain link plus space

and time. chain link for the real time

and space and time for complex questions

that facilitate SQLS SQL style analytics

onchain

right today uh when teams want to ask a

complex question from a smart contract

think all the D5 protocols we know and

love if they're actually sending data

like like like a SQL answer to a smart

contract they're usually doing that

offchain and usually with a centralized

oracle they built themselves right this

This is teams that are doing centralized

data indexing into for example a

Postgress database that they're

operating themselves on for example AWS

which for example will probably go down

via the last presentation we all

listened to and and then that Postgress

database they're using a centralized

server to have their smart contract a

DeFi developer smart contract query some

data for example I'm building a new

lending protocol all and I would like to

know who's borrowing from me. So when a

wallet connects to borrow, I'd like to

query their previous borrow history. I'd

like to query, have they already paid

off loans, have they been liquidated,

and how much and when. Maybe I give you

a better borrow rate if you've already

paid off loans in the past. What's

shocking to everyone and was shocking to

me when I first started in crypto is

like there's no database on chain. The

EVM has no way to ask that simple

question, a question as simple as, "Has

Scott's wallet already paid off loans on

chain?" There's no way from a Solidity

smart contract in Solidity to look up

that historical information and run that

complex aggregation, looking up my

wallet over time, finding all of my

lending transactions, and adding up how

much I borrowed or how much I got

liquidated or how much I paid off.

Let's usher in a new era of datadriven

smart contracts. Chainlink issued in

issued in the the first era, right? Defi

summer that was ushered in by price

feeds. Chainlink built this very robust

and very forward-thinking solution for

providing price feeds to smart contracts

so that DeFi developers could finally

access some data in solidity and make

DeFi decisions like liquidating a loan.

Now, take that a step further. The next

generation provides historical

aggregation, asset providence, and to

derive metrics like, hey, for this

wallet, show the balance of that they've

been holding of this stable coin and for

how long. I mean, we'll give them extra

rewards if they've been holding a

certain stable coin or staking a certain

token like space and time token for a

certain amount of time. historical

aggregation like hey if the total volume

of RWA out RWA outflows across this

bridge is greater than X amount over

seven days execute some some logic to

like mint more and increase our

collateral.

This datadriven next generation of smart

contracts is necessary for institutions

to actually deploy complex logic on

chain. Like if if a major American bank

wants to, you know, build a new money

market on chain backed by their bond

collateral or tortill collateral, for

example, it's not as simple as just slap

an oracle in the middle and you're done.

There's complex questions that need to

be asked to stabilize that stable coin

and peg it to the value of their assets.

And space and time allows those smart

contracts to run ZK proven queries by

sitting in the middle. And the best part

is this can be done through chain link.

We've integrated with chain link. So for

devs that are already comfortable with

chain link, already building with chain

link, already calling chain link from

their smart contracts, they can call

space and time through chain link if

they're more comfortable doing that. The

point is space and time listens for all

of Ethereum's activity, events, you name

it. collects all that in a zk proven

tamperproof BFT consensus driven way

and then when a smart contract wants to

ask a question they just call the space

and time contract or call chain link

either one next block space and time

returns back to the defi dev back to

their contract the SQL query answer

already verified on chain

what this ushers in is

verifiable indexing a D5 protocol asking

questions about their own events, their

own activities, as well as verifiable

off-chain data. A a bank loading in a

bunch of history of bond prices and then

making decisions on chain that relate to

those bond prices. Right

now,

today, space and time is a network of

about 20 validators that are listening

to Ethereum, listening to ZK sync,

listening to other L2s like base or

other, you know, all L1's like Hyperlid.

And we're coming to consensus that we've

collected the right data. We're building

new cryptographic proofs that the data

hasn't been tampered since we've grabbed

it from Ethereum. And SXT is the utility

token that we stake on those validators

and we pay the validators in SXT in

order to run queries. So a smart

contract developer on Ethereum uh

would call the space and time relayer

contract and say, "Hey, give us some

data back." And they'd pay an SXT. That

SXT goes to the validator set goes to

the stakers. So, we're constantly

iterating and constantly improving our

staking and and creating new value for

our stakers and new rewards programs.

Today, uh we're we're talking about an

8% yield. And we'd love those in the

audience that are chain link stakers

that have received SXT as chain link

rewards to go stake it with the space

and time network and earn that yield.

And we've been so pleasantly surprised

at the amount of um participation from

the chain link community. It's it's been

nothing but incredible. Like, you know,

going back, we we're always thinking,

hey, being born in the chain link

ecosystem set space and time up for

success in such an incredible way with

the space with the link stakers

supporting the space and time network.

So, for stakers in the audience, I want

to encourage you to run a validator.

It's very easy to run a to stand up and

and start operating a space and time

validator and join the network. And of

course, for for for uh delegated stakers

in in the community, grab SXT and stake

it. We're ushering in a new era of

datadriven smart contracts. And if

you're a smart contract developer and

you want to start asking questions from

a smart contract and building with SQL

onchain like you're already used to,

come contact space and time. And uh

today we're just we're very proud to

have announced space and time v2 which

allows institutions to create their own

tables self-custodied on space and time

chain. We just announced that today here

at SmartCon. We always come to SmartCon

with some kind of exciting announcement.

So, uh, space and time is not just

collecting data from the major chains.

It's also allowing banks to put their

own tables in space and time, load their

own off-chain trada, and then query it

from their smart contracts with ZK

proofs.
