Papyrus has successfully deployed prototype smart contracts on Ethereum Mainnet, and executed a series of dRTB transactions.
Technical details:
- After passing the audit by Ambisafe, the prototype PRP token was deployed.
- The prototype Papyrus DAO with registries for all ecosystem participants (SSPs, DSPs, Auditors and Publishers) and payment channel managementinfrastructure was deployed.
- Accounts for test DSP gateway, SSP gateway and Auditor were created and debited with small amounts of PRP tokens (10 units each) minted for the testing purpose.
- Then test accounts were registered in the Papyrus registries with a PoS deposit of 10 PRP units each, resulting in DAO now holding 30 PRP units.
- The DSP gateway was credited 1 PRP to be used for payments, and created a payment channel to the SSP gateway with a 1 PRP deposit.
- 10 dRTB interactions were simulated between the gateways resulting in 10 micropayment transactions 0.1 PRP each sent through the channel, locked until Auditor’s signature is provided.
-Auditor’s signatures for 8 out of 10 micropayments were provided, the remaining 2 micropayments were not signed (emulating fraudulent impressions).
- The DSP gateway closed the payment channel, with its deposit of 1 PRP distributed between DSP and SSP gateways — 0.2 PRP returned to DSP gateway as unconfirmed, and 0.8 PRP transferred to SSP gateway as confirmed.
- The Auditor submitted the fraud statistics for the closed channel, resulting in reputation update for DSP gateway.
Now the contracts remain operational on the mainnet, ready to support the coming registrations of new participants and integrations with our first partners.
