HEAT- 100% new code.
- Segmentable blockchain (you can run a node only with the last segment).
- POS & POP (Proof of presence: the node having and seeding the rare segments of the blockchain gets rewarded).
- Outstanding 1000 TX/s rate (very much scalable).
- Very easy to set up a node and forge.
- Great tools for developpers to build microservices (sort of like smart contracts but executed on nodes instead of the blockchain), see heat-dev-kit on the github if you are a developper, you'll understand how great this tool is.
- Blockchain-based trading: sell & buy orders recorded on the blockchain.
- Only 13M market cap now, will go very much higher in a near future.
