In which @socrates1024 and I will be joined by the amazing [Deli Gong](https://github.com/Gnnng) and [Zheng Leong Chua](https://github.com/melynx) (@czl) from Automata for demos and discussions.

Featured will be:

- The most recent **TEE speedrun under 1000 LoC** prototypes - [dstack](https://collective.flashbots.net/t/dstack-speedrunning-a-p2p-confidential-vm/3876) (@socrates1024)
- Automata’s [recently open-sourced](https://blog.ata.network/releasing-dcap-library-v4-a-unified-interface-to-verify-tees-on-chain-2f27538babb4) [**on-chain PCCS**](https://github.com/automata-network/automata-on-chain-pccs)
- and [**RiscZero-powered ZK SNARK proofs of attestation**](https://github.com/automata-network/dcap-rs?tab=readme-ov-file) that reduce gas needed for on-chain verification of attestations **by 16x**!
- A discussion of how the above can together disrupt how TEEs and blockchains interact

This call has it all! Join us 2024-09-27T13:00:00Z→2024-09-27T14:20:00Z on [flashbots.net/live](https://flashbots.net/live).
