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.
Plutons are digital tokens issued to users on the Ethereum blockchain, these are native to the Plutus app. To provide an analogy, these tokens are similar to cash back or frequent flier miles. As a user, you will automatically be rewarded with a 3%* rebate in Plutons for every Bitcoin deposit you make towards a purchase. Plutons can be used within the Plutus app in the same way as Bitcoins. This means that you can use Plutons to charge your contactless balance just as you would with BTC, with the added benefit of zero fees and instant conversions.
