Flowchain whitepaper summary
What is Flowchain
Friends, imagine countless smart devices around us—like smart home gadgets and sensors in smart factories—constantly generating massive amounts of data. If this data can be securely and instantly collected and processed, it can create tremendous value. But traditional technologies often struggle to be both fast and secure. The Flowchain (FLC) project is like a “data superhighway” tailor-made for these smart devices, leveraging blockchain technology to enable peer-to-peer (P2P) real-time data exchange and transactions between IoT devices, while ensuring the security and trustworthiness of the data.
The project’s target users are mainly enterprises, especially those that need to process large volumes of IoT data for real-time analysis and decision-making. For example, in healthcare, Flowchain’s technology can help professionals ensure that data collected from medical devices like smartwatches is authentic and tamper-proof.
Simply put, Flowchain aims to solve the core problem of how, in a future where IoT devices are exploding in number, data transmission between these devices can be lightning-fast and as secure as a bank vault.
Project Vision and Value Proposition
Flowchain’s vision is to provide enterprises with a comprehensive “Data 2025 Ready” solution. “Data 2025” refers to the prediction that by 2025, over 150 billion IoT devices will be connected globally, most requiring real-time operation. Flowchain believes that current IoT technologies cannot deliver this real-time processing capability, and their solution fills this technological gap.
The core problems it aims to solve include: enabling real-time data transactions for IoT, building more secure and cost-effective IoT systems, ensuring trusted communication between devices, protecting data privacy, and maintaining data integrity. Flowchain’s uniqueness lies in designing blockchain technology from scratch for IoT, adopting a hybrid blockchain architecture, unique “virtual block” technology, and “Pseudonymous Public Key Infrastructure” (PPKI), and advancing the project in an open-source manner.
Technical Features
Flowchain’s technology is like a meticulously designed traffic system, ensuring the smooth and secure flow of IoT data:
Hybrid Blockchain Architecture
Flowchain adopts a “hybrid blockchain” design, akin to a city with both public highways and private lanes. It consists of a public blockchain and multiple private blockchains. The public blockchain acts as the city’s central hub, handling transactions requiring high transparency and trust, and providing AI computing power. Private blockchains are like dedicated lanes, deployed at the “edge” of IoT devices, processing data that demands high real-time performance and privacy, ensuring efficiency and speed in data handling.
Virtual Blocks
This is a core innovation of Flowchain, which can be understood as a special “data packaging” method designed for real-time data transactions. In traditional blockchains, all nodes compete to package blocks and synchronize all data, consuming significant time and resources. Flowchain’s “virtual block” mechanism allows each IoT device (node) to independently mine and package data on its own “branch,” without needing to synchronize with all other nodes. This greatly accelerates data processing—like each device having its own dedicated ledger to quickly record information, without waiting for network-wide consensus.
Pseudonymous Public Key Infrastructure (PPKI)
For IoT devices, traditional cryptographic authentication (PKI) is resource-intensive and energy-consuming—like asking a small electric car to haul a heavy truck’s load, which is inefficient. Flowchain introduces PPKI technology, providing IoT devices with real-time, random, and unique public keys for fast and secure authentication without heavy resource consumption. It works by having miners on the public blockchain generate “puzzles” and “Lambda” values, then hybrid consensus nodes broadcast the puzzles to IoT devices. The device that solves the puzzle fastest gets authenticated, enabling trusted communication.
Consensus Mechanism
Flowchain’s public blockchain uses a hybrid of Proof-of-Work (PoW) and Proof-of-Stake (PoS), while private blockchains mainly use PoS. This hybrid mechanism aims to balance decentralization, security, and efficiency. (Proof-of-Stake: a blockchain consensus mechanism where validators lock up tokens to earn the right to validate transactions and create new blocks, rather than competing via computational power.)
P2P IoT Networking
The Flowchain operating system enables IoT devices to form a decentralized peer-to-peer network—like a connected community of smart devices that communicate directly, without centralized servers. It also utilizes MIT’s Chord algorithm for efficient device and data location lookup within the network.
Tech Stack
Flowchain nodes are primarily built with Node.js, and its implementation is 100% JavaScript-based, making deployment on IoT devices highly flexible.
Tokenomics
Flowchain’s native token is FLC, which plays a vital role throughout the ecosystem.
Token Utility
- Payment Tool: FLC can be used to pay for Flowchain’s products and services.
- Transaction Fees: Users pay FLC as transaction fees to block producers (miners) in the network.
- Data Security & Validation: FLC, combined with “tokenized IoT hardware,” ensures the security and validity of IoT data.
- Miner Rewards: FLC is used to reward miners who contribute resources to the network. These miners include:
- Hybrid Node Miners: Contribute network bandwidth.
- IPFS Node Miners: Contribute storage space for deploying and storing Flowchain decentralized application (DApp) data.
- AI Node Miners: Contribute GPU computing power to run Flowchain DApps.
- Utility Token: FLC is considered a utility token and can be used to pre-purchase Flowchain products and services.
