[ocdbytes]

Features

• Added assumption verification inside guest code.
• Added proof submission to local nexus client.
• Added SP1 implementation for ethereum adapter.
• E2E flow working in mock proof mode for r0 and sp1.
• Added tracing in ethereum adapter.
• Added bls12_381 acceleration for sp1 prover.
• Updated Helios version to support latest beacon chain updates.

To build the adapters and nexus

1. To build/run nexus client :

   cd nexus/host
   cargo build --no-default-features --features "sp1"/"risc0"
   
   # To run
   RUST_LOG=info cargo run --no-default-features --features "sp1"/"risc0"
   
   # If running in dev mode for risc 0
   RISC0_DEV_MODE=true RUST_LOG=info cargo run --no-default-features --features "risc0" -- --dev
   
   # If running in mock mode for sp1
   RUST_LOG=info SP1_PROVER=mock cargo run --no-default-features --features "sp1" -- --dev
   
   # If running in cuda mode for sp1
   RUST_LOG=info SP1_PROVER=cuda cargo run --no-default-features --features "sp1"

2. To build adapters :

   cd examples/<adapter_name>
   cargo build --no-default-features --features "sp1"/"risc0"
   
   # To run
    RUST_LOG=info cargo run --no-default-features --features "sp1"/"risc0"
   
   # If running in dev mode for risc 0
   RISC0_DEV_MODE=true RUST_LOG=info cargo run --no-default-features --features "risc0" -- --dev
   
   # If running in mock mode for sp1
   RUST_LOG=info SP1_PROVER=mock cargo run --no-default-features --features "sp1" -- --dev
   
   # If running in cuda mode for sp1
   RUST_LOG=info SP1_PROVER=cuda cargo run --no-default-features --features "sp1"

3. To run in cuda for adapters in risc0 :

    RUST_LOG=info RUSTFLAGS="-C target-cpu=native" cargo run --no-default-features --features "risc0-cuda"
