Company I
Company I
blockchain-based ‘self-sovereign wallet’ DID solution and platform for issuing and submitting certificates of degrees
-
Background
- Personal data leaks occur frequently due to lack of proper care when personal data is provided to web or mobile services
- Users have to frequently repeat such troublesome procedures as sign-up to use different web and mobile services
-
Solution
- Create an Hdac private blockchain to protect sensitive information such as personal data
- Store user identification data in the user’s PC or mobile environment using Hdac blockchain technology
- Provide APIs accessible to DIDs and Hdac blockchain networks
-
Expected Effect
- Allow secure use of web and mobile services, without any privacy or leakage issues
- Enable use of distributed IDs across various areas, including issuance of certificates such as degree certificates, as well as banking services

Company H
Blockchain-based document management solution
-
Background
- A digital contract document that the insurance company and client entered into can be stored on a WORM (Write Once Read Many system, which does not permit changes)
- A separate WORM (Write Once Read Many system) independent of a general server is used, causing additional costs and things that need to be controlled
-
Solution
- Create an Hdac private blockchain on an ordinary server that the user has used
- Provide an Hdac blockchain-based document management solution using the irreversibility of the blockchain
-
Expected Effect
- Reduce infrastructure costs by allowing electronic insurance contracts to be stored on an ordinary server, without having to buy extra equipment

Company K and H
Company K and H
Blockchain-based electronic contract solution
-
Background
- In case of a general contract, a dispute arises from a contract document management system, which is managed offline, such as denial of contractual existence
- Since the obligation to use authorization certificates and the provision of predominance of law wabolished following an amendment to the Digital Signature Act, it has become possible to provide a blockchain-based digital signature service equivalent to existing digital signatures that employ authorization certificates
-
Solution
- Create an HDAC private block chain to which only a client or a partner appointed by the client can access and use to protect corporate data
- Existing ActiveX-based certificates can be replaced by Hdac blockchain-based certificates
- Implement the contract process using ‘Multisig (multisignature),’ one of the features of the Hdac blockchain
-
Expected Effect
- Prevent data forgery by changing the file-based document management system into the blockchain-based multisig transaction system
- The user can expect the final product to increase in value by building a private blockchain and share information with their partners
