Project Description
Unlike ordinary crypto dashboard in web3 or traditional bank statement in web2, Chain Statement offers the following features that will improve privacy and smooth-onboarding-experience in web3.
Proof of Identity using zero knowledge 😊 Decentralized Storage of Account Information 🌐 Low-cost and lightning-fast Ethereum L2 blockchain ⚡ User-friendly decentralised Ethereum scaling platform 💸
How it's Made
Proof of Identity using zero knowledge 😊 It is easy to get the transactions data based on address, but how can you prove that this address belongs to you? By using the zero knowledge features from semaphore, we allow user to generate unique identity which can be used to proof their identity and fetch their own chain statement. Users will generate their own identity based on
User Name Birth Date Passport Number Password Once the identity commitment is recorded on semaphore protocol, user only need to insert their information again and our platform will automatically generate proof for user. Once they are verified, they can download chain statement immediately.
Decentralized Storage of Account Information 🌐 We are aware that censorship is a big problem in traditional financial services. Thus, we solve this problem by storing our user's chain statement on IPFS, in a form of PDF which consists of: User can receive their chain statement which consits of:
Balance of each assets from multiple chains and addresses User's Name User's Passport Number Low-cost and lightning-fast Ethereum L2 blockchain ⚡ We don't want our users to pay high gas fee for just a simple generating chain statement request. Hence, our smart contract is deployed on Optimism, which is a Optimisitic-Rollup L2 blockchain that has low-cost and lightning-fast transaction experience.
User-friendly decentralised Ethereum scaling platform 💸 User-friendly is also another main consideration for us when we're developing Chain Statement. With cheap transaction fee, strong community support and user-friendly characteristics, we deployed our smart contract to Polygon.
