Project Description

eCourt: Justice on the Blockchain with Sign Protocol The Problem: Our current legal system is slow, expensive, and prone to errors. Disputes drag on for months, costing everyone involved time and money. Trust in the system is often low due to lack of transparency.

The Solution: eCourt is a revolutionary court case management system built on the Arbitrum Sepolia blockchain, a secure and scalable testnet environment.

How it Works:

Open Cases Securely: File cases with clear details and pay filing fees securely using cryptocurrency. Immutable Evidence: Submit evidence directly to the blockchain, ensuring it cannot be tampered with. Real-Time Tracking: Track case progress in real time, with all authorized parties having access to the latest information. Verifiable Verdicts: Settle disputes with verifiable verdicts created using Sign Protocol, a secure attestation system, guaranteeing the authenticity of the outcome. Benefits:

Increased Transparency: All case activity is recorded on the blockchain, fostering trust in the system. Reduced Costs & Delays: Faster resolution times and streamlined processes lead to lower costs. Secure Evidence Storage: Eliminate the risk of tampering with evidence stored immutably on the blockchain. Immutable Case History: Maintain a permanent and verifiable record of all case activity. The eCourt Advantage:

Smart Contract on Arbitrum Sepolia: Our smart contract is already deployed, allowing for real-world development and testing before full launch. Sign Protocol Integration: Verifiable attestations from Sign Protocol ensure the authenticity of every step in the process.

How it's Made

Tech Stack:

Solidity: We used Solidity, a high-level programming language specifically designed for writing smart contracts on the Ethereum Virtual Machine (EVM). The eCourt smart contract manages case data, fees, and user interactions.

Arbitrum Sepolia: eCourt is deployed on the Arbitrum Sepolia testnet, a secure and scalable layer-2 blockchain built on Ethereum. This allows for fast and cost-effective development and testing before full mainnet deployment.

Sign Protocol: eCourt integrates with Sign Protocol, an omni-chain attestation protocol. We leverage Sign Protocol's capabilities to create verifiable attestations for case details and verdicts. These attestations ensure the authenticity and immutability of critical case information.

Putting it Together:

Case Initiation: When a case is opened, relevant details like plaintiff, defendant, and case specifics are stored on the eCourt smart contract. The filing fee is collected in cryptocurrency and securely held within the contract.

Evidence Submission: Users can submit evidence directly to the blockchain. This evidence becomes part of the permanent and immutable case record, eliminating the risk of tampering.

Case Progression Tracking: The smart contract tracks the case progress, allowing authorized parties to view the latest updates in real-time. This transparency fosters trust and reduces the need for manual information sharing.

Dispute Resolution: When a case reaches a verdict, a verifiable attestation is created using Sign Protocol. This attestation captures the verdict details and is cryptographically signed, ensuring its authenticity and preventing modifications. Benefits of Partnering with Sign Protocol:

Verifiable Attestations: Sign Protocol provides a secure and reliable way to create verifiable claims about case information. This strengthens the trustworthiness of the entire eCourt system.

Reduced Disputes: By using verifiable attestations, eCourt minimizes the chances of disputes regarding case details and verdicts.

Decentralized Trust Model: Sign Protocol's decentralized nature removes the need for a central authority to verify information, fostering a more transparent and trust-based legal system.
