5. Why Gnosis Chain
An established sister chain to
Ethereum with a rich history (and
cheaper fees)
Same composite architecture as
Ethereum, with same Execution
and Consensus Layer.
Not just another
EVM Chain
Gnosis takes the IBC model of
Cosmos in the form of ZK Bridges
to trustlessly connect Ethereum
and other Beacon Chain-based
EVMs
Building an
Ethereumverse
Gnosis is the third most
decentralized chain next to
Bitcoin and Ethereum. For more
information visit https://d14n.info/
Highly Decentralized

8. Would you trust
these companies
with your savings?
DeFi needs security…
…and security needs
decentralization
Chain Number of Validators
Ethereum 440,263
Gnosis Chain 106,746
Cardano 2,076
Avalanche 1,199
Cosmos Hub 175

9. Unique dual-token model
xDai is a stable token used for transactions, payments, and fees
GNO for Proof of Stake protection with the consensus-layer
BTC + Lightning does not have sufficient
bandwidth to allow every human to open a state
channel at birth and close it 80 years later
How much gas do you want
to pay for your coffee?
$100?
1$?
<$0.01?

10. ZK Bridges are a game-changer
- Recent innovation in ZK allows for “trust-minimized” bridging (e.g. “proof-of-
consensus”)
- “Ethereum stack” based chains (e.g. EL, CL) allow for common bridge standard

15. An “Ethereumverse” approach to scaling
“Ethereumverse”
Keeps the tooling and dev mindshare of Ethereum,
and the battle-tested “Ethereum stack”
Gnosis takes the IBC model of Cosmos in the form of ZK Bridges to trustlessly connect
Ethereum and other Beacon Chain-based EVMs
…as compared to Cosmos IBC
Allows L1s to trustlessly connect in a horizontal
architecture

17. Fully permissionless Meta DEX Aggregator,
leveraging the Coincidence of Wants…
… and using batch auctions with uniform clearing prices

Solver
18. Sow how
does it
look?
1) Orders are completed and split into batches
(Orderbook component)
2) Each batch is sent to multiple solvers
3) Each solver sends its solution to the driver (think Jury)
4) Driver ranks all candidate solutions using a well
defined scoring function
5) Best solution is settled on-chain
