Proofplum is the first live application on Algorand 2.0

Documents, certificates and identities are scattered across many devices and cloud services. These documents include details about some facts such as ownership, authenticity or achievements. To check for validity and proof, everyone should go back to the issuer. The issuer then checks against their own database and provide response. This validation happens every single time. Also, anyone can edit the PDF or image certificate to alter the name or achievement. And that is why the issuer need to verify the authenticity every single time.

Blockchain certificate solves this problem by creating a tamper proof digital certificate. When the issuer creates the certificate, they anchor the claim in a public blockchain. This means, even a single bit of data change will make the certificate invalid.

The promise of blockchain is that individual should be able to own and prove the Authenticity of a transaction without a middlemen.

Algorand 1.0 solved the blockchain trilemma (Security, scalability and decentralization) in a public blockchain. Algorand 2.0 provides many layer-1 pre built functionality such as ASA (Algorand Standard Asset). ASA is equal to ERC-20 smart contract in Ethereum. It provides many features such access controls, transfer assets and represent different types. These can include fungible, non fungible, restricted fungible and restricted non fungible assets.

At Proofplum, anyone can drag/drop a PDF or image file and create tamper proof digital certificate registered on the blockchain. Proofplum is using ASA (Algorand Standard Asset) to store the document information as a standard asset. The information about the document is filled into asset name, total amount and url.

Proofplum uses Blockcerts certificate format. Blockcerts, developed by MIT is a open standard for creating, issuing, viewing, and verifying blockchain-based certificates.

Creating a digital certificate is the first step for tokenization and securitization. Once a physical thing such as a piece of land has a tamper proof digital identity then it is easy to perform complex financial transactions. There are a range of existing transactions that rely on intermediaries to provide trust and execution. Our belief is to make intermediaries obsolete and avoid unnecessary delays and costs.

User experience for any blockchain based applications (aka DApps) are always bad. You need a wallet, crypto currency and lots of patience to use it. Not anymore. At Proofplum.com we hide all these complexities. Signup with your email, login and drag/drop any document to see the it work. No crypto currencies or wallets required.

It is always better to see it in action to believe it. Go ahead, sign up at https://proofplum.com .
