VSK Chains: Integrated Content and Currency Transaction Blockchains

We present a computational system for handling, in an integrated manner, distributed transactional information and the associated monetary payment information, arising in typical organizational applications. Our paper contains three ideas: (i) a conceptual architectural design for chains of blocks of content transaction chains, (ii) a conceptual architectural design for blocks of financial instrument transaction chains including a proposed form of denominational digital cash, and (iii) a new, versatile cryptographic hash function to support all the chaining operations. In the total design, the transactional and financial information are chained together. We call these chains the VSK chains. Our system consists of centralized, auditable chains to manage distributed transactions of: (i) financial instruments (such as coins, tokens, or coupons used as a medium of exchange) and (ii) associated transactions of plain content (such as documents, or mail). The digital cash and the blockchains of our system can be adapted to models of decentralized blockchains, akin to cryptocurrencies, using proof-of-work/proof-of-stake computational principles. We have recently proposed a new key stream generator based on certain types of collections of arithmetic progressions of integers. Our scheme provides for enhanced flexibility and versatility with respect to parametric choices.We build our hashchains using the integer sequences derived from this collection. We present an outline of prototype development and implementation of certain modules of the VSK chains system.
