Problem:

Current IoT networks are facing great challenges by uneven connectivity, poor scalability, absent trust, cracked security and broken business due to limitations of current TCP/IP architecture. Current TCP/IP architecture is run based on Domain-centric Networking approach, designed 40 years ago. With Domain-centric Networking, IoT platforms provide a centralized server to aggregate IoT devices, data and services and manage them, which leads to poor scalability and high bandwidth consumption. The number of IoT devices is predicted to be increased to 20 billion devices by 2022, and the current infrastructure limits the growth potentials and profitability of IoT.

Example:

Self-driving car: Network transmits navigation information to smart gadgets. Error in the transmission (whether it’s caused by DNS, IP, or internet network) could cause serious accidents.

Solution:

Blockcloud aims to solve the current problems with IoT by developing an advanced TCP/IP architecture based on a new consensus mechanism (Proof of Service) for verification of services and efficient ledger structure (CoDAG) for fast transaction writing. Blockcloud combines (1) a Service-centric Networking (SCN) approach to provide reliable connectivity and global scalability and (2) the blockchain technology to achieve a trust, secure and incentivized IoT infrastructure. Additionally, smart contract operated double auction will be used to fairly price and match services providers and users.

Technology:

Network Layer - Service-centric Networking: an internet technology that provides a service-aware network stack, where applications communicate on service names instead of IP addresses. Traditional TCP/IP infrastructure is designed for fixed entities in stable environment, and with the growing number of mobile/IoT devices it has created great challenges in mobility and scalability.

1. Mobility solution

Service-centric paradigm enables name-based routing that connects clients to services, seamlessly changes network addresses, migrates flows across interfaces, or establishes additional flows for efficient and uninterrupted service access required by mobile/IoT devices.

2. Scalability

On Blockcloud services and data are decentralized with peer-to-peer technology, achieved from the adoption of a Distributed Hash Table (DHT) network.

Note: Compatible with today’s internet and can evolve over time. Can run over IP. Services are published/subscribed to/from the network.

Application Layer - Blockchain operates on top of SCN to provide trust, security, fairness, economic incentive.

Service Access Layer (SAL) - The SAL maps service names in packets to network addresses, based on rules in its service table managed by a blockchain. Unlike traditional “service layers” which sit above the transport layer, the SAL’s position below transport provides a programmable service-level data plane that can adopt diverse service discovery techniques

Note: This is to enable communications on service names, not exact endpoints who provide the services. Thus endpoints can change network addresses with uninterrupted service assess. Think DNS

Proof of Service consensus provides trust and security to Blockcloud infrastructure, by having distributed miners, economically incentivized to be honest, to check services provided to the network and guarantee the trust. Blockcloud believes that successful decentralization of IoT lies in being trustless so that there is no need for participants to be trusted or centralized.

Compacted Directed Acyclic Graph (CoDAG) - transaction recording structure

The CoDAG structure is different from chain-like structure, as it adopts a flexible structure that is more suitable for asynchronous operations. It is also different with previous DAG-based structure, it adopts a more compacted structure, where nodes are more well connected. Intuitively, CoDAG is more like a well-connected channel, and the width of the channel can be adjusted according to user demands.

Truthful Continuous Double Auction (TCDA) - fair service distribution

The Blockcloud team develops a truthful continuous double auction (TCDA) mechanism that allows users to bid for service. TCDA has the following properties:

· Defending against price cheating

· Cheating traders can not increase the profit so that they do not have incentives to cheat.

· Guaranteeing fairness

· TCDA treats sellers and buyers equally, where sellers and buyers have the same opportunity to earn profits.

· Minimizing trading maintenance cost.

· TCDA optimizes the trading maintenance cost to scale the system to support a large number of trading simultaneously.
