2/ In the Chrono V1 paper (https://arxiv.org/pdf/2310.08373), we explored the reasoning about event ordering in the presence of Byzantine participants.

3/ That paper introduced the Decaying Bloom Onion Clock (DBOC), which ensures fault-tolerant causal relationships among events in distributed systems. 🌐 It focused on the theoretical foundations of Byzantine event ordering and reduced false positives of logical clocks.

5/ These clocks have built-in proofs that are verifiable by anyone, and enable secure causal reasoning even in Byzantine environments. 🔒The clocks are compact and produce no false-positives.

7/ Chrono V2 comes with three VLC backend implementations: i. Quorum signature-based for efficient proof generation ii. Trusted Execution Environment (TEE)-based for secure attestation iii. Incrementally Verifiable Computation (IVC)-based for strong cryptographic guarantees using recursive proofs ⚙️
