About Def Chain

DEFCHAIN aims to disrupt the world of expensive and underpowered cloud computing by using the blockchain to decentralize processing power to millions of ARM processors across smart devices during their idle periods.

Through the patented algorithm and communication protocol specifically designed for ARM chips, Defchain harnesses the blockchain technology to integrate the idle computing power and bandwidth of millions of smart devices around the world. This gives birth to the world’s first light blockchain ecosystem for smart devices.

The new sharing economy

  • Everyone can be part of the new sharing economy
  • The lowest layer for the entire blockchain ecosystem
  • Powerful desktop class smart devices will power the blockchain
  • Over 10+ million smart devices are already part of our ecosystem

DEF Chain in 90 seconds

Technical value

The only smart device public chain in the world, a new “light blockchain” as a result of the technological breakthroughs achieved in many blockchain basic technology areas.


Commercial value

The global personal idle network resource sharing platform will greatly reduce the current high cloud service costs by as much as 90%.


Channel value

Based on the advanced Plug framework, DEF uses the POW+POS consensus mechanism. TPS has reached 2000+ – this has been verified on more than 30 chains such as Wanda and McDonald’s.


  • Decentralization is the trend of cloud services. However, there is currently no cloud resource operation platform for blockchain in the world.
  • Most of the existing blockchain technologies rely on PCs and servers.
  • Existing blockchain nodes are few and the dispersion is relatively low, resulting in efficiency and throughput bottlenecks.
  • At present, the cost of a single node in a blockchain is very high, which hinders the popularity of blockchain.


  • Develop a new “light blockchain” based on ARM devices to enable smart devices to be on the blockchain.
  • Design an advanced token economy, motivate smart devices to chain up and share resources.
  • Make the syste m compatible with existing cloud service interfaces to enable resource users to “zero workload” migration.
  • Redesign the distributed database system to accommodate hundreds of millions of nodes.
  • Reconfigure the P2P algorithm based on the intelligent device signaling structure to improve transaction efficiency.

No one is better suited to do this than US.

Technological innovation: we are the only ARM public chain


DEF is the only company that realizes the complete transplantation of blockchain to ARM devices. This is not only a breakthrough in blockchain technology, but also a revolution in cloud computing: turning massive IOT smart devices into providers of cloud service infrastructure.


DEF’s incentive mechanism makes smart devices easier to share idle resources. We adopt AI mining based on the users’ usage habits, network attributes, resource conditions and other big data


Based on the advanced Plug framework, DEF uses the POW+POS consensus mechanism. TPS has reached 2000+ – this has been verified on more than 30 chains such as Wanda and McDonald’s.


Support DEF and help create the world’s largest ‘light blockchain’ ecosystem for smart devices based on ARM processors.Be a part of this revolution. Be proud.
