A digital asset is value recorded on a secured distributed ledger
What the document says“The term "digital asset" means any digital representation of value that is recorded on a cryptographically secured distributed ledger.”
Paragraph (6). The definition turns on two things: a digital representation of value, and a record of it on a cryptographically secured distributed ledger. Paragraph (8) defines distributed ledger as technology in which data is shared across a network that creates a public digital ledger of verified transactions or information among network participants, with cryptography used to link the data.
What the document actually says“The term "digital asset" means any digital representation of value that is recorded on a cryptographically secured distributed ledger.”
A digital asset is value kept as a computer record. The record sits on a shared, locked ledger.
A ledger is a list of who owns what. A shared ledger is kept on many computers at once. Math locks the list so old lines cannot be changed.
