Abstract
Digix provides a u ca for the tokenisation and documentation of physical asts through its
1
Proof of Ast (PoA) protocol. The PoA protocol utilis Ethereum and the InterPlanetary
2
古代人的日常生活Files System (IPFS) to track an ast through its chain of custody. This allows for the open and public verification of an ast’s existence without a centralid databa. Digix also offers an API allowing other applications to be built on top of our ast tokenisation rvice.

Key Products
1.Proof of Ast (PoA) Ast Cards
PoA Ast Cards consist of the below information permanently uploaded onto the
decentralid databa:
Time Stamp of card creation
SKU of the gold bar
Bar Serial number
Chain of Custody digital signatures (Vendor, Custodian, Auditor)
Purcha Receipt
Audit Documentation

PoA Ast Cards are kept in an Ethereum Wallet.
2.Digix Tokens (DGX)
Dgx Tokens are minted via a Minter Smart Contract. Each DGX token reprents 1g of Gold and divisible to 0.001g. For every PoA Card that is nt to the Minter Smart
Contract, DGX tokens will be issued in return. For instance, a 100g PoA Card nt to the Minter Smart Contract returns 100 DGX tokens to the ur.怎样养君子兰

Key Process
座右铭诗句There are 3 modular process that Digix us to provide a proof of existence and fungibility for an a
st, 1 for redemption of physical asts, and 1 that encourages Ða pp Development. Tho process consist of:
1.Proof of Ast (PoA) Verification p rocess which records and provides an audit trail of
an ast on Ethereum to create PoA Ast Cards. The ast cards are certified using
quential digital signatures from the entities in the chain of custody, namely, the
Vendor, Custodian, Auditor, which are further validated with proof of purcha and
depository receipts provided and uploaded onto IPFS for permanent record (Fig i).

The PoA Verification contains a sub process for regular audits as shown in (Fig ii).

2.Minter Smart Contract t o create fungible DGX tokens, that accepts or holds PoA Ast
Cards in exchange for DGX tokens (Fig iii).
