Is this correct?

1. Crypto currency is a digital asset. It is designed to work as a medium of exchanging ''value''. It uses cryptography to secure its value, to create additional units and to verify transactions.

I do not get the ''it is designed to work as a medium of exchanging ''value'' part. And what does ''uses cryptography to secure its value'' mean? What is the ''value here''?



2. Blockchain is a continously growing list of records called ''blocks''. They are linked and secured using cryptography. Each block contains all sorts of informations such as ''hash pointed'', which points to the previous block, timestamp and transactions data. Blockchains are inherently resistant to modification. It is also described as an open, distributed ledger that can record transactions between two parties in a verifiable and permanent way.

What does the ''securing transactions in a VERIFIABLE way mean? How is it be verified?
