Tokens are minted via a Minter Smart Contract. Each DGX token represents 1g of
Gold and divisible to . For every PoA Card that is sent to the Minter Smart
Contract, DGX tokens will be issued in return. For instance, a 100g PoA Card sent to the
Minter Smart Contract returns 100 DGX tokens to the user.
Digix Tokens are held in an Ethereum Wallet.
Key Processes
There are 3 modular processes that Digix uses to provide a proof of existence and fungibility for
an asset, 1 for redemption of physical assets, and 1 that encourages Ðapp Development. Those
processes consist of:
1. Proof of Asset (PoA) Verification process which records and provides an audit trail of
an asset on Ethereum to create PoA Asset Cards. The asset cards are certified using
sequential digital signatures from the entities in the chain of custody, namely, the
Vendor, Custodian, Auditor, which are further validated with proof of purchase and
depository receipts provided and uploaded onto IPFS for permanent record (Fig i).Figure i: Digix Asset Registration ProcessThe PoA Verification contains a sub process for regular audits as shown in (Fig ii).
Figure ii: Audit Process2. Minter Smart Contract to create fungible DGX tokens, that accepts or holds PoA Asset
Cards in exchange for DGX tokens (Fig iii).
Figure iii: Minting Digix Gold Asset Cards into Digix Gold Tokens3. Recaster Smart Contract, which is used to exchange DGX tokens back into PoA Asset
cards. (Fig iv).
