Implemented a comprehensive Kani verification script to automate formal verification processes for various blockchain functionalities, including cryptographic operations, transaction integrity, and mining statistics. - Created multiple verification harnesses for core blockchain operations in `src/blockchain/kani_verification.rs`, covering mining stats, difficulty adjustment, and block hash consistency. - Developed cryptographic verification harnesses in `src/crypto/kani_verification.rs` for ECDSA and FN-DSA signatures, encryption type determination, and transaction integrity. - Added modular architecture verification harnesses in `src/modular/kani_verification.rs` for message priority, layer state transitions, and orchestrator coordination. - Introduced basic Kani tests in `src/basic_kani_test.rs` and `src/simple_kani_tests.rs` to validate Kani setup and demonstrate verification of simple properties. - Created utility macros in `src/kani_macros.rs` to streamline common verification tasks and assertions. --- Cargo.lock | 87 +++-- Cargo.toml | 4 +- Makefile | 133 +++++++ build.rs | 3 + docs/KANI_VERIFICATION.md | 228 ++++++++++++ kani-config.toml | 36 ++ kani-verification/Cargo.lock | 304 ++++++++++++++++ kani-verification/Cargo.toml | 11 + kani-verification/run_verification.sh | 159 +++++++++ kani-verification/src/lib.rs | 8 + kani-verification/src/verify_basic.rs | 123 +++++++ kani-verification/src/verify_blockchain.rs | 389 +++++++++++++++++++++ kani-verification/src/verify_crypto.rs | 210 +++++++++++ scripts/run_kani_verification.sh | 204 +++++++++++ src/basic_kani_test.rs | 11 + src/blockchain/kani_verification.rs | 236 +++++++++++++ src/blockchain/mod.rs | 3 + src/crypto/kani_verification.rs | 213 +++++++++++ src/crypto/mod.rs | 3 + src/kani_macros.rs | 169 +++++++++ src/lib.rs | 10 + src/modular/kani_verification.rs | 304 ++++++++++++++++ src/modular/mod.rs | 3 + src/simple_kani_tests.rs | 144 ++++++++ 24 files changed, 2963 insertions(+), 32 deletions(-) create mode 100644 Makefile create mode 100644 docs/KANI_VERIFICATION.md create mode 100644 kani-config.toml create mode 100644 kani-verification/Cargo.lock create mode 100644 kani-verification/Cargo.toml create mode 100755 kani-verification/run_verification.sh create mode 100644 kani-verification/src/lib.rs create mode 100644 kani-verification/src/verify_basic.rs create mode 100644 kani-verification/src/verify_blockchain.rs create mode 100644 kani-verification/src/verify_crypto.rs create mode 100755 scripts/run_kani_verification.sh create mode 100644 src/basic_kani_test.rs create mode 100644 src/blockchain/kani_verification.rs create mode 100644 src/crypto/kani_verification.rs create mode 100644 src/kani_macros.rs create mode 100644 src/modular/kani_verification.rs create mode 100644 src/simple_kani_tests.rs diff --git a/Cargo.lock b/Cargo.lock index aa6b12e..953d138 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1020,23 +1020,6 @@ dependencies = [ "cfg-if 1.0.1", ] -[[package]] -name = "creusot-contracts" -version = "0.6.0-dev" -dependencies = [ -

Consolidated and reordered imports in various files for better readability and organization. - Removed unnecessary whitespace and ensured consistent formatting in the codebase. - Enhanced the structure of the modular blockchain architecture by refining the layout of modules and their components. - Added a rustfmt configuration file to enforce consistent code style across the project. - Updated test files to align with the new import structure and formatting standards. --- Makefile | 36 +------ README.md | 6 +- benches/blockchain_bench.rs | 26 ++++- build.rs | 2 +- config/polytorus.toml | 2 +- docs/API_REFERENCE.md | 10 +- docs/DEVELOPMENT.md | 52 ++++----- docs/DIAMOND_IO_CONTRACTS.md | 10 +- docs/GETTING_STARTED.md | 2 +- docs/MODULAR_ARCHITECTURE.md | 6 +- docs/NETWORK_ARCHITECTURE.md | 2 +- docs/README.md | 4 +- docs/TPS_REPORT.md | 6 +- examples/diamond_io_demo.rs | 5 +- examples/diamond_io_demo_new.rs | 5 +- examples/diamond_io_demo_new_fixed.rs | 5 +- examples/diamond_io_performance_test.rs | 5 +- examples/diamond_io_performance_test_fixed.rs | 5 +- examples/modular_architecture_simple.rs | 6 +- examples/network_demo.rs | 10 +- examples/simple_difficulty_test.rs | 11 +- rustfmt.toml | 10 ++ src/basic_kani_test.rs | 2 +- src/blockchain/block.rs | 28 +++-- src/blockchain/kani_verification.rs | 78 +++++++------- src/blockchain/mod.rs | 5 +- src/command/cli.rs | 11 +- src/config/enhanced_config.rs | 11 +- src/config/mod.rs | 10 +- src/crypto/ecdsa.rs | 10 +- src/crypto/fndsa.rs | 12 ++- src/crypto/kani_verification.rs | 68 ++++++------ src/crypto/transaction.rs | 44 +++++--- src/crypto/types.rs | 5 +- src/crypto/verkle_tree.rs | 41 +++++-- src/crypto/wallets.rs | 44 ++++++-- src/diamond_io_integration.rs | 8 +- src/diamond_io_integration_new.rs | 38 +++---- src/diamond_smart_contracts.rs | 2 +- src/kani_macros.rs | 10 +- src/modular/config_manager.rs | 18 +++- src/modular/consensus.rs | 12 ++- src/modular/data_availability.rs | 14 ++- src/modular/diamond_io_layer.rs | 30 ++++-- src/modular/eutxo_processor.rs | 27 +++-- src/modular/execution.rs | 28 +++-- src/modular/kani_verification.rs | 76 ++++++------- src/modular/layer_factory.rs | 19 +++- src/modular/message_bus.rs | 13 ++- src/modular/mod.rs | 102 +++++++++++++----- src/modular/network.rs | 8 +- src/modular/settlement.rs | 16 ++- src/modular/storage.rs | 28 +++-- src/modular/tests.rs | 7 +- src/modular/traits.rs | 6 +- src/modular/transaction_processor.rs | 21 +++- src/modular/unified_orchestrator.rs | 26 +++-- src/network/blockchain_integration.rs | 35 ++++-- src/network/message_priority.rs | 36 +++++-- src/network/mod.rs | 25 ++++- src/network/network_config.rs | 5 +- src/network/network_manager.rs | 31 ++++-- src/network/p2p_enhanced.rs | 66 +++++++++--- src/network/p2p_tests.rs | 2 +- src/simple_kani_tests.rs | 40 +++---- src/smart_contract/contract.rs | 16 ++- src/smart_contract/engine.rs | 18 +++- src/smart_contract/state.rs | 11 +- src/smart_contract/types.rs | 6 +- src/test_helpers.rs | 4 +- src/webserver/createwallet.rs | 13 ++- src/webserver/listaddresses.rs | 7 +- src/webserver/network_api.rs | 21 +++- src/webserver/printchain.rs | 6 +- src/webserver/reindex.rs | 6 +- src/webserver/server.rs | 18 +++- src/webserver/startminer.rs | 7 +- src/webserver/startnode.rs | 7 +- tests/diamond_io_integration_tests.rs | 5 +- 79 files changed, 1002 insertions(+), 487 deletions(-) create mode 100644 rustfmt.toml diff --git a/Makefile b/Makefile index 7d44ba1..bdc57a0 100644 --- a/Makefile +++ b/Makefile @@ -1,6 +1,6 @@ # Makefile for Polytorus Kani Verification -.PHONY: kani-install kani-setup kani-verify kani-clean kani-quick kani-crypto kani-blockchain kani-modular help +.PHONY: kani-install kani-setup kani-verify kani-clean kani-quick kani-crypto kani-blockchain kani-modular kani-security kani-performance kani-watch kani-report pre-commit ci-verify kani-dev kani-list kani-check dep-check kani-ci help # Colors for output BLUE := \033[0;34m @@ -101,29 +101,6 @@ kani-performance: kani-setup cd kani-verification && timeout 120 cargo kani --harness verify_hash_determinism cd kani-verification && timeout 120 cargo kani --harness verify_synchronization_mechanism @echo "$(GREEN)Performance verification complete!$(NC)" -
