We wish to provide a short summary as to why Spectrum is part and parcel of ongoing developments for DGX 2.0

All current users of the Digix beta app are advised to migrate any ETH / DGX / POA Cards stored in their current digix lightwallet into the standard ethereum wallet JSON file that is compatible with Spectrum and DGX 2.0. Instructions can be found here. This allows us to retire support for DigixCore 1.0 / Beta Wallet. The Digix Beta Wallet was created and implemented in January of this year as a POC during Ethereum’s first phase — Frontier, and due to further developments on Ethereum, it will no longer be maintained and would be replaced by Spectrum.

2. Spectrum as a light wallet service for DigixCore 2.0

Our lightwallet will allow users to store DGX and Proof of Asset digital cards (POA cards represent itemized and serialized gold bullion assets). Spectrum allows POA Card asset information to be displayed in full (audit trail / detailed information) within a light wallet. Hence, Spectrum as a light wallet service helps us with a better UI UX for DGX 2.0 products.

3. Allows us to quickly build to market DGX 2.0 peripherals after launch

Spectrum will allow us to easily set up simple carbon-style votes for early basic propositions, such as voting on whether to sell off ETC in DigixDAO.

4. Internal support/PoA signing tools used in DigixCore 2.0 will use Spectrum

Digix vendors will be using Spectrum to sign off on all audit trail / Proof of Asset documents to demonstrate the existence of gold in our vaults. (Information of the POA protocol can be found at www.dgx.io/whitepaper.pdf)

DigixSupplier, DigixCustodian, DigixAuditor, DigixAdmin are the PoA related Digix Vendors.

Vendors require a UI to sign for delivery of item (DigixSupplier), to sign for custodian receipt of the item (DigixCustodian) and to submit the quarterly audits (DigixAuditor).

DigixAdmin UI allows us to manage who our supplier, custodian, auditor (by authorizing a set of keys that could sign on the PoA card)

A Digix vendor would only need an internet connection to quickly load up the spectrum dapplet specific to their role with zero installs.
