The CoinDesk Digitization Index (DTZ) is designed to measure the market capitalization weighted performance of digitization protocols that are included in Digital Asset Classification Standard (DACS). Inclusion of a digital asset in DTZ is subject to minimum trading and exchange eligibility requirements. DTZ reflects the DACS as of the prior month, so Digitization refers to the process by which real world documents, contracts, public names, etc. are uploaded to a blockchain for the purpose of transparency, publicly verifiable ownership, and immutability. Proof of ownership, identity and authenticity are both valuable traits that are made possible by blockchain technology.
