Area of Science:

Computer Science
Information Technology

Background:

Blockchain immutability poses challenges for big-data integration, causing issues with redundancy, scalability, cost, and latency.
Large data volumes in blockchains lead to wasted energy and storage resources, increasing demand for data deletion capabilities.
Existing blockchain data modification methods often have slow deletion times and insufficient security.

Purpose of the Study:

To propose a novel blockchain architecture, Unlichain, that enables data modification features within public blockchain systems.
To address the limitations of current blockchain technologies in handling big data, specifically regarding data deletion.
To improve efficiency, reduce storage, and enhance security in blockchain data management.

Main Methods:

Developed Unlichain, a novel blockchain architecture featuring a new indexing technique for predefined and unknown lifetime data deletion.
Implemented a metadata verification consensus mechanism among full and meta nodes to minimize delays and storage overhead.
Designed block mining incentives that encourage nodes to scan for and delete expired data.

Main Results:

Unlichain successfully achieves instant data deletion, unlike existing solutions hampered by block dependency.
Evaluations demonstrate a reduction in storage usage by up to 10% compared to conventional methods.
The proposed metadata verification consensus effectively avoids delays and reduces extra storage requirements.

Conclusions:

Unlichain offers a viable solution for integrating big data with public blockchains by enabling efficient and secure data deletion.
The architecture significantly improves upon existing methods by addressing deletion delays and storage inefficiencies.
Unlichain enhances blockchain utility for big-data applications through its innovative approach to data lifecycle management.
