Good evening. when coins will be released to the stock exchange? thank you

One of the biggest problem for digital advertising is ad fraud. The price for that is quite clear — over $16.4 billion and it’s still growing. In digital advertising the transfer of value goes through the following axes: advertiser-publisher-user. Advertisers bid for ad placements, publishers accept the bid, the ad impression is delivered, the ad is filled and the user’s ID is matched with that ad impression ID.

As blockchain is essentially a decentralised storage for all the transactions, and it has proven efficiency in finance and multiple other industries, then it could be a great idea to use in digital advertising, so that the value can be saved and not wasted if we implement mathematical proof and decentralisation, right?

Actually, there’s some doubts that blockchain can change the situation. Recent article by Forbes presents some concerns regarding it. The argumentation is simple: up to this date blockchain technology is very slow to handle that much number of transactions. For instance, Bitcoin’s blockchain process 7 transactions per second, whereas Ethereum’s one — around 13 transactions per second. In case of advertising, a single transaction occurs every time as ad is viewed. With millions of as impressions being delivered every second, it’s just not possible for the current technology development to process that much information.

So the question is really important. Why the Papyrus digital advertising platform will be a game changer?

It’s true that large ad networks and publishers generate hundreds of billions of ad clicks and at least two times more ad impressions annually. Using current technology any attempt to execute smart contracts for digital advertising will generate excessive costs. Our solution utilises an extension of the technology called state channel that is capable of supporting these high loads.

The idea of a state channel is not new. It underlies the scale-up solutions for Bitcoin and Ethereum ( as well as Lightning Network and Raiden Network). Papyrus is one of the first to customize it for the specific needs of AdTech. The technology aggregates state logs from DSPs, SSPs, and auditors. So the realisation of payment is based on the constant log exchange among parties.

In the typical state channels system the transaction takes place when the critical mass of obligations occurs (e.g. Bob owes Alice an amount of $). In the case of adtech, such a system would be feasible because of the need for a revision of impressions/clicks by an external auditor that will come later on. In the Papyrus ecosystem the auditor takes a direct part in the formation of the payment. This system is more efficient for adtech as all parties receive payments after all verification procedures.

Here is an example:

- Participants make deposits in the locker (thereby fixing some of its state) and then directly exchange with each other payments in the form of appropriately drawn up and signed transactions of the relevant block. This changes the balance of deposits in favor of one or the other participant.

- Participants transfer the updated state of the blockchain (in the part related to their deposits) to each other and they can do this arbitrarily (of course, within the limits of deposits) without the costs of carrying out transactions in the detachment.

- The final state is recorded in the blockchain only once — when the channel is closed. Or if one of the participants finds the incorrect behavior of the other. Let’s say that the participants will send about 200 thousand micropayments (for a total of $ 200) through one channel. In our initial assumptions this gives several tens of millions of channel opening / closing transactions per month. This is not trillions of transactions per month, but still too much for immediate processing in a public blockchain.

Papyrus has another solution: we can develop the idea of direct transmission of updates to the state of the blockchain outside of it and apply this approach directly to the opening / closing logic of the channel (originally performed in the blockchain). Let’s look at the opening / closing transactions for the dedicated nodes that will exchange the calculated updates of the public lockdown state with each other only occasionally publishing them to the blockchain itself (to update the balance of payments between the participants). The work of such nodes can be organized as a highly specialized block based on the Proof-of-Stake consensus where the blocks consist exclusively of opening / closing transactions. Participants will make large PoS deposits in a public blockchain and will be penalized for improper handling of these transactions.

To ensure guarantees of invariability and verifiability a specialized blockchain can lean on a public block writing down hashes of its blocks of transactions. Suppose one block of a specialized blockchain contains about 1 thousand transactions of opening / closing channels — in our initial assumptions this gives several tens of thousands of transactions in a public detachment a month. It already looks realistic, for example in the Ethereum network the current daily volume is hundreds of thousands of transactions.

The use of state channel libraries in Papyrus will facilitate the opening and maintaining of a peer-to-peer state channels network. Leveraging the developments of Lightning Network and Raiden Network the Papyrus ecosystem will introduce state channels adopted for usage in decentralized RTB protocol. The overall idea under that is to enhance the scalability of the Papyrus ecosystem.

In the first half of 2018 we are planning to develop and test Papyrus Protostar Release with:

- Libraries for dRTB Event Log Storage

- Libraries for dRTB State Channels Network

- Libraries for Auditor integrations and more.

With 20 connected partners (at the moment) we will present a first approximation of our future digital advertising platform. This is about real work, our passionate and talented team, and the deep desire to make advertising better. Stay tuned!

Hi! Could you kindly text to our bounty manager in Telegram? We will investigate your case.

Hi papyrus.global! Are you going to answer my question, which I asked above? I'm still waiting for your answer.

eth network is still congested...

seems not the best time for presale 

anyway, hope it will be possible to distribute last airdrop soon, just can't do it from Monday LOL

Review for the last year and action plan for 2018

Looking back at 2017 is a great motivation for 2018. Much of the hardwork for 2018 has been laid throughout the year, which means that this new year will be even more successful.

This summer Papyrus first announced an idea to change digital advertising world and attracted $1M for initial platform development. Through the development process we brought on board world class strategic partners like Bancor, WINGS, Airpush, BitClave and others. We have successfully deployed our prototype in Ethereum mainnet and raised $500.000 during the TGE Round 1.

In the upcoming 2018, we plan to: 

• In Q1 we plan to start pilot integrations with real businesses and launch second Token Generation Event;
• In the first half of the year we plan Papyrus Protostar Release development and testing with 20 connected partners;
• In the second half of the year we will present Papyrus Protostar Release — first comprehensive release of all Papyrus components with 50 connected partners.

We believe that together we can make a great thing. Thank you for your patience, passion and trust in Papyrus.

I was promote the project in Twitter and received 3 coins too )
Taking consideration that Papyrus had has some problems with their website on pre-sale I'm not surprised about my bounty-rewards)
Despite on all these points I'm hope that the project will be active and PPR tokens will be demanded

Thank you sir, now everything has become transparent and very clear. I think will be no more questions from participants bounty

Technical Roundup #7

During the last few recent weeks our team has been actively developing our product and is almost ready to launch the first real ad purchase through the Papyrus ecosystem.

We are now testing and improving the beta version of the Papyrus node. The Papyrus node is a set of components developed by our team that is responsible for interacting with the blockchain and providing a gRPC API. All existing software vendors such as DSP, SSP and auditors can interact with ecosystem through this API. In the development of the Papyrus node, our team was able to solve the very difficult issues of highload and scaling.

One of the important tasks solved by the Papyrus node is storing, retrieving, and exchanging data. We have already implemented a local file protocol and begin to test the interaction via IPFS.

A great use of the Papyrus node is in performing validation and the formation of the Papyrus blockchain blocks. Any participant in the chain, including the advertiser and the publisher, can setup the Papyrus node in order to validate the data.

It is with great pride I can say that our team has developed a whole framework for processing blocks that can be used even outside the advertising ecosystem.

In the near future we plan to open the source code of the Papyrus node and provide instructions for deployment on any server.

In order to show the capabilities of Papyrus, we made a small demonstration DSP, which allows you to purchase traffic through the Papyrus ecosystem.



In this DSP you can already create advertising campaigns. To check the correctness of DSP campaign statistics you can do it in a separate amazing software called Papyrus scanner, which we will release in the very soon. The Papyrus scanner is a kind of Etherscanner for the Papyrus blockchain that will allow any member of the ecosystem to check its purchase chains.

Recently we have been actively working on the SSP Gateway, which will allow purchasing inventory from publishers that are not yet fully integrated into the Papyrus ecosystem. We have achieved a lot of success so far, taking into account the support of several RTB protocols.

We are getting very close to the launch of advertising sales through Papyrus!

Hello everyone!

The bounty program totaled 16 888, 583 tokens. Transfers were made for 16,815, 07 tokens for 1458 participants. For 16 participants (for the remaining 72.93 tokens) the transfers will be made separately due to the fact that they indicated the invalid addresses of their wallets (mails will be sent to them). We will mail them and send the tokens as soon as they provide relevant information.

Papyrus team appreciates all the efforts from contributors to promote the project in the worldwide level. The ultimate reason for such a scrupulous analysis of bounty was the deep desire to fairly reward participants. It should be taken into account that the number of participants for some categories of the bounty were extremely high (e.g. Facebook, Twitter), whereas for others it was not. It also affected the number of stakes distributed. All in all we expect a long-term relations with our community as we are to launch the second round of bounty (associated with the second TGE planned in Q1 2018). The detailed description will be provided later.

As for results of the current campaign, the detailed table can be found here:
https://docs.google.com/spreadsheets/d/1Dfwbf025eyxncQwK58pzv7JPA4j3-dOQMFU81iYVf5g/edit#gid=1548759372

What the difference does it make if our rewards bounty are frozen. We can't move tokens

When you add the shares of the first 5 participants, a different number is obtained from the list, but the number of tokens is different. some participants have only 40 shares of the blog and they get like participants with 750 shares of the total. I personally only share twitter, share Facebook -0 with the fact that I participated for 2.5 months and post all the records of the FB. Summing up, I want to thank as always with Russian roots. keep up the good work. lazy to count, do not worry about how they will treat you after the campaign. the main thing is to get a profit, the rest does not care) all the benefits

thank you for adding tokens.
but very little of the tokens you gave me. 

Exchanges will be announced shortly before the start of TGE Round 2 (Q1 2018)

Papyrus will be introducing two different utility tokens: PRP or Papyrus Prototype Token that will be used in the ecosystem prototype; and PPR or Papyrus Permanent token that will be used in the permanent version of the ecosystem. For more details please read our blog.

the same question, what is the price of 1 prp .. and where is the exchange for this coin

i got 38 PRP, so what about price for each 1 PRP ?

Can someone please tell be the difference between PPR and PRP

15% of the PPR token supply will be distributed among the PRP token holders in exchange for their PRP tokens and proportionally to their PRP holdings at the end of Round 2.

Hello. Please on what exchange is PPR? I know there is something that should be done to change PRP to PPR but I don't seem to remember. Please can someone remind me. Thanks in advance.
