Strong is a blockchain agnostic protocol that rewards nodes for supporting the infrastructure of their blockchain.
Strong seems to incentivize nodes due to limited resources and lack of incentive makes so many nodes run out of date software, maintain incomplete blockchain history and often being offline.
Through incentive and governance Strong prioritizes the safety and sustainability of node rewards compounding value for token holders by regularly reducing supply and only Ethereum 1.0 full nodes are eligible for STRONG rewards.
STRONG is the native token of Strong and it is ERC20 based, Strong is the first and only that rewards nodes.
