Radium is a Proof-of-Stake cryptocurrency that serves as the base blockchain for SmartChain Core which expands the utility of Radium far beyond that of a standard coin, with features such as identity-address linkage, proof-of-existence, file checksum verification and validation, and decentralized elections and voting. All of these features exist in a 100% distributed data-layer within the Radium blockchain.
Telos is a new blockchain network based on EOSIO software. Eos and Telos are both networks running the EOSIO software. Any smart contract that runs on one system should run equally well on the other. Telos has modified the Eos genesis snapshot and some rules to make the network more responsible to the majority of token holders, to be more attractive to DApp developers, and to generally run more responsively and sustainably. TLOS is the name of the token that reflects ownership in the Telos network. A TLOS token is like an EOS token except that there will be around 3X fewer TLOS tokens than EOS.
