How We Build Evidence Market​

1. Smart Contract Build Core​

  • Immutability and Irrevocability: Based on cryptographic security, the contract is immutable and irrevocable once created, eliminating uncertainty.

  • High Transparency and Accuracy: Smart contract code is open and transparent, executing based on underlying mathematical principles. This avoids the ambiguity and inconsistencies caused by human interpretation in traditional contracts, ensuring predictable results.

  • Elimination of Human Credit Risk: Credit risk is replaced by rules. Transactions can be completed simply by trusting the code. In smart contracts, execution is automatic once the conditions are met, and execution cannot be refused.

2. Privacy Computing Shield​

Based on the TEE (Trusted Execution Environment) of Oasis Sapphire, built on Intel SGX, it provides hardware-level security protection, which is considered highly secure under current computing models.

3. Distributed Storage (Permaweb)​

Integrating IPFS and Arweave, evidence files are shredded and stored. This eliminates the risk of single points of maliciousness or failure.

Privacy and Security​

1. On-chain Anonymity​

  • Project contracts: Users can interact via relayer proxies (through the ERC2771 standard), achieving on-chain untraceability.

  • Privacy token: ERC20privacy supports EIP-712 signature authorization transactions, and there is no contract event log output, realizing token transactions without leaving traces on the blockchain.

2. AES + EDCH Symmetric Encryption​

AES-256 is widely considered secure under existing computing models, possessing an extremely high threshold for cracking.
