In the ERP and SaaS world, technically every accounting entry is passed 2 times (once in Service provider books of account & once in Service receiver books of accounts), leveraging private blobs, namespaces and a blob posting syntax specific to ERP, we can build a router (TCP/IP) which transports business messages to destination business namespaces.
For example, an accounting entry can be passed just once in 1 ERP rollup with a destination ERP namespace, and the router will ping the immutable business transaction in the receiver ERP, leading to immutable on-chain business truth. This leads to autonomous and real time accounting removing reliance/trust placed on Accountants, Auditors and inturn reducing frauds and corruption in Financial reporting of businesses.
