Ho dato una rapida occhiata a quei link. Non ho capito
1) il registro pubblico decentralizzato sui cui si poggia questo sistema di pagamento é la blockchain dei bitcoin o un'altra blockchain creata ad hoc?
2) si possono trasferire sia btc sia IOU (dei pagherò relativi a euro o a dollari); ma chi garantisce la riconversione IOU -> euro?
CARD LOADING
In a prepaid transaction mode, the Mycelium card is loaded from fiat currency (government-issued money) such as USD, EUR or others, converted into IoUs units.
“IoUs” are seen as a payment promise, which is technically embodied thanks to the blockchain metadata protocols, such as "colored coins".
The Colored Coins is a concept that allows attaching metadata to blockchain transactions and leveraging the distributed ledger infrastructure for issuing and trading immutable digital assets that can represent real world value.
Mycelium uses Colu.co’s Colored Coin Platform that is built upon the Colored Coin platform. Colored coins are digital IOUs, their value is the one promised by the issuer.
In a debit card or credit card mode, the issuer will make its affair of debt, or potential debt, incurred by the cardholder, and load “IoUs” in the Card.
