OFFICIAL ANN  IOTEX THREAD - https://bitcointalksearch.org/topic/annmainnet-preview-iotex-a-decentralized-network-for-internet-of-things-4955975


Founded as an open-source project in 2017, IoTeX is building the world’s leading privacy-centric blockchain platform for the Internet of Things (IoT).

IoTeX mission is to build a decentralized trust fabric for a new era of collaboration and data exchange among devices, applications and people. Backed by a global team of research scientists and top engineers, IoTeX combines blockchain, trusted hardware and edge computing to realize the full potential of IoT.

The IoTeX project is dynamically developing according to the Roadmap

The development progress can be observed on the Github
Right now, anyone can take part in testing the IoTeX network
Participate in the IoTeX Bug Bounty from 02/12/2019 to 04/01/2019 - Medium
To strengthen the team, the IoTeX project constantly requires developers and programmers
IoTeX - the developer of innovative blockchain solutions - is open for mutually beneficial partnership and cooperation
IoTeX Mainnet — Staking/Voting & The Grand Design, you can findmore information on Medium
To ensure the smooth operation of the IoTeX decentralized blockchain network, the IoTeX project conducts a set of Delegates
Staking is now OPEN on IoTeX Delegates website and you can join it now - Medium

The project team includes leading experts in the field of blockchain technologies and engineering, cryptographic sciences, and community development managers. Founders of the project:





• Testnet Preview (codename StoneVan) - the first release of the IoTeX code took place on April 21, 2018. IoTeX classifies the main functions into four groups: TBC (Transactions, Block & Chain), Network, Consensus, and Testing & Integration. IoTeX selected golang to develop the IoTeX blockchain.

• Testnet Preview (codename Strive) - the second release of the IoTeX code took place on June 28, 2018. In this release, IoTeX presented basic blockchain features such as transaction and block handling, gossip protocol over P2P network, pluggable consensus framework, and initial remote procedure call (RPC) support.

• Testnet Beta Preview (codename Epik) - the third release of the code took place on August 30, 2018. The release presented key features: support of Ethereum Virtual Machine and smart contracts, IoTeX Wallet implementation, Roll-DPoS consensus and simulation enhancements, BLS signature and DKG implementation, work-preserving upgrades, support of 100+ physically distributed nodes.

• Mainnet Preview (codename - Photon) - a preview of the main IoTeX network took place on November 16, 2018. The release includes new features: sub-chain provisioning; cross-chain communication; consensus enhancements; IoTeX Explorer v2.0 (separate IoTeX Explorer pages to visualize both root chain and sub-chain activities).

IoTeX is committed to ensuring compatibility with IoT, so that all devices and systems can work autonomously, to scale, by implementing the full meaning of IoT. Almost all existing blockchains have limitations when operating in the IoT environment, since they are not designed to handle a large number of IoT devices, are heterogeneous and have various limitations in calculation, storage and power.

IoTeX is designed as a next generation blockchain that is designed to handle all the complexities in the IoT world. IoTeX developers focused on scalability, cost reduction, and confidentiality — the three biggest issues that limit the effectiveness of other blockchain solutions. The main innovations are:

1. Blockchains-in-Blockchain Architecture
IoTeX is a network of many blockchains that are hierarchically arranged where many blockchains could run concurrently with one another while retaining interoperability. In the IoTeX world, as shown in the Figure above, the root blockchain manages many independent blockchains, or subchains. A subchain connects to and interacts with IoT devices that share something, e.g., they have a similar functional purpose, operate in similar environments, or share the similar level of trust. If a subchain does not function well, e.g., being attacked or experiencing software bugs, the rootchain is completely unaffected. In addition, cross blockchain transactions are supported to transfer value and data from subchains to the rootchain or from one subchain to another via the rootchain.



2. Built-in Privacy-Preserving Transaction
The transaction information in the blockchain is not confidential. The transaction amount and the assets being transferred, its metadata, and its relationships to other transactions, can be trivially learned by anyone. In total, three aspects of confidentiality can be distinguished: confidentiality of the sender, confidentiality of the recipient and confidentiality of transaction data. IoTeX integrates stealth address for receiver privacy, ring signature for sender privacy and Pedersen Commitments for hiding transaction amount with the following innovations and improvements: a lightweight stealth address scheme is designed to exempt receivers from scanning the entire blockchain to be aware of incoming transactions, and ring signature is optimized to make it compact in size without a distributed trusted setup.

3. Roll-DPoS IoTeX Consensus Mechanism
To have a fast and efficient consensus mechanism with instant block finality in the context of IoT, we combine the concepts of DPoS, PBFT and Veriable Random Functions (VRFs). Roll-DPoS is an internal IoTeX consensus mechanism that extends the capabilities of DPoS to support subchain architecture and large-scale DApps IoT. Roll-DPoS improves the performance of the existing DPoS, making it scalable (with a dynamic pool size of delegates of nodes with automatic scaling depending on the block size), more democratic, i.e. less centralized (allowing more and more nodes to participate in the consensus) and more protected from attacks (using an innovative randomized algorithm used to select the manufacturers of the blocks that actually participate in the consensus).
Roll-DPOS is adapted for the IoTeX blockchain and has four main phases: selection of candidates, formation of a committee, proposal of a block, and completion of a block.



4. Fast Consensus and Instant Finality of Transactions

Block finality is the guarantee that the new block generated is final and cannot be changed. Block finality impacts the concrete implementation of cross-chain communication substantially as one subchain has to wait until block finality is achieved (at least with high probability) on the sending blockchain
before accepting an incoming cross-chain transaction. Using real-time consensus with instant termination solves the problem of instant finalization, since the receiving chain has a guarantee with one block confirmation in the sending block chain. It is expected that for IoT applications, the inter-blockchain transfer of values and data will be fast and cost-effective, which requires real-time consensus for both the root chain and the subchains. IoTeX consensus achieves instant block finality as one of his many features designed to fit the Internet of Things future applications.
