Decentralized FaaS over Multi-Clouds with Blockchain based Management for Supporting Emerging Applications
Function-as-a-Service (FaaS) offers a streamlined cloud computing paradigm, but existing centralized systems suffer from vendor lock-in and single points of failure. We propose DeFaaS, a decentralized FaaS system leveraging blockchain technology and decentralized API management. DeFaaS addresses these limitations by establishing a secure, transparent registry of functions on a blockchain and enabling applications to discover and invoke them. This approach fosters scalability, flexibility, enhan…

Advancing Blockchain Scalability: A Linear Optimization Framework for Diversified Node Allocation in Shards
Blockchain technology, while revolutionary in enabling decentralized transactions, faces scalability challenges as the ledger must be replicated across all nodes of the chain, limiting throughput and efficiency. Sharding, which divides the chain into smaller segments, called shards, offers a solution by enabling parallel transaction processing. However, sharding introduces new complexities, notably how to allocate nodes to shards without compromising the network's security. This paper introdu…

Towards a low carbon proof-of-work blockchain
Proof of Work (PoW) blockchains burn a lot of energy. Proof-of-work algorithms are expensive by design and often only serve to compute blockchains. In some sense, carbon-based and non-carbon based regional electric power is fungible. So the total carbon and non-carbon electric power mix plays a role. Thus, generally PoW algorithms have large CO$_2$ footprints solely for computing blockchains. A proof of technology is described towards replacing hashcash or other PoW methods with a lottery and p…
