RENO, Saha. WeaveChain: A decentralized storage framework using Arweave to address scalability, security, and decentralization challenges. SACJ [online]. 2025, vol.37, n.2, pp.104-120. ISSN 2313-7835.  https://doi.org/10.18489/sacj.v37i2.22359.

Blockchain systems persistently struggle to balance scalability, security, and decentralization - the fundamental trilemma hindering enterprise adoption. Existing solutions like Filecoin compromise decentralization when scaling throughput or face security vulnerabilities under adversarial conditions. Motivated by the urgent need for practical trilemma resolution in storage-intensive applications (e.g., medical records, IoT coordination), this study introduces WeaveChain: a novel framework leveraging Arweave's permanent storage to simultaneously optimize all three dimensions. Our primary aim is to architect a decentralized storage system that achieves: 1) high-throughput transaction processing, 2) provable security against Byzantine failures (malicious or faulty nodes acting arbitrarily), and 3) egalitarian network participation - without mutual trade-offs. By implementing compact 48-byte transaction anchors and adaptive block sizing (1-200MB), the system processes 7,200 transactions per megabyte block, reaching 162 TPS. Comprehensive testing demonstrates 0.82 chain quality under 40% adversarial influence, 99% lower storage than Bitcoin, and Sybil attack resistance. These results establish a new paradigm for trilemma resolution where permanent data anchoring enables scalable, secure, and truly decentralized blockchain storage.
