Saturday, June 811:35 - 11:55 AMNicolas LaraBlockchain EngineerOsmosisAccount Abstraction ChallengesI will be presenting the x/smart-accounts module. Review the technical design, problems that needed to be addressed along the way, how to build authenticators, and the upcoming obstacles to tackle:
* Signing fees separately from the rest of the tx (to allow solvers to independently submit txs signed by others)
* Dealing with interchain txs (now that addrs on one chain can’t be derived from one another)
* Meta-accounts (keeping custom user data linking their accounts)

Saturday, June 812:00 - 12:20 PMLaurens KubatCTO & Co-FounderQuasarDecentralizing Off-Chain ProcessesDecentralizing Off-Chain Processes with Validator Networks in the Cosmos Ecosystem

Many protocols need certain actions to be done off-chain, whether it be hosting a frontend, aggregating data from an indexer, submitting some further permutation of that data on a chain, or verifying information.

* Generally the fast and easy solution for this is to centralize this and to decentralize this later. Most of these problems require specific infrastructure to solve and would also need a validator set to delegate this work to function decentralized.
* We have built and are expanding on some infrastructure that further decentralizes these processes and brings them onchain.
* We currently have two use cases: the Quasar strategy keeper network to provide attestations for the Quasar strategy updates and a decentralized network to off-chain index osmosis transactions and provide incentives based on this data instead of the limited on-chain system.

A large part of this infrastructure is generalizable to other systems and also able to be used for dapps, especially it allows a dapp to add economic security to its ecosystem by staking/restaking certain assets, to give the dapp the benefits of having a validator network to do work without becoming a chain.

Saturday, June 83:45 - 4:05 PMReece WilliamsProtocol & Tooling EngineerStrangeloveLocal-Interchain: Easy IBC TestnetsI'll take developers through an interchaintest (from Strangelove) tool I built called Local-Interchain for easy testnet environments & interaction with any language. This is for both local and remote testnets (used by Ethos) which has Cosmos & Eth support for multichain applications. It will discuss how we make others lives easier by abstracting away needless complexities and let you focus on your live environment testing without the current hassle, solely with JSON. This sounds a lot like Starship from Cosmology, but we also have multi-language interaction support Including Go, Rust, Python. Will walk through IBC examples with this and github CI.

This presentation will explore the technical architecture and capabilities of open-source project Instagoric, a tool designed to streamline and simplify the on-demand deployment of testnets on cloud platforms within the Agoric ecosystem. We'll delve into how Instagoric can be utilized by other Cosmos ecosystem projects to deploy their own testnets efficiently, focusing on aspects such as automated scaling, monitoring and alerting, and cost-effective resource management. The session will include a live demonstration of setting up a testnet, along with insights on best practices for maintaining stability and performance.

Sunday, June 911:10 - 11:30 AMMatt BellCo-FounderNomic / TurbofishBuilding Light Clients into FrontendsDecentralizing Frontend Infrastructure - When Tendermint and Cosmos were originally created, it was assumed that clients would verify the data they receive. However, the Cosmos status quo is instead to take shortcuts and get data from trusted CometBFT RPC, gRPC, LCD, and indexer servers. We show how it is possible for projects to build verifying light clients into their apps to remove the need for centrally-run infrastructure.

Sunday, June 92:30 - 2:50 PMEthan BuchmanCEOInformal SystemsPrivacy Preserving Sidecar for CosmWasmPrivacy Preserving Sidecar for CosmWasm


We built a new framework for adding privacy-preserving functionality to any CosmWasm chain. It operates using a trusted execution enclave (TEE) “side-car”, using the TEE for privacy (i.e. SGX), with the option of adding zero-knowledge proofs to reduce dependency on the TEE. Building the framework involved the following novel developments:
- CosmWasm merkle proofs (prover + verifier)
- EPID + DCAP remote attestation in CosmWasm
- Light-client based protocol for pairing the trusted enclave with a CosmWasm contract to mitigate attacks
- CometBFT stateless verifier on CosmWasm + prover utility
- Risc0 ZK verifier on CosmWasm


The goal of the framework is to be agnostic to the underlying applications, and to allow both stateless and stateful applications. We plan to extend it to include a TEE key manager so that execution can be distributed across multiple TEEs.

Sunday, June 94:35 - 4:55 PMDev OjhaContributorOsmosisNext Directions in ConsensusMany key product and application breakthroughs for decentralization and user improvements live at the consensus layer. People often hypotheticate that these require sacrificing on public verifiability — this is false.
Many of the consensus improvements really map to 2 core problems: 1) Censorship Resistance and, 2) Throughput Scaling.

We categorize how many frequently seen techniques map onto these ideas, and a potential path for prioritizing and getting these into Cosmos.
