Dear Pirl Community,

As you know as part of the newly launched Pirl Projects Incubator program, we held a contest for Projects who wanted to host their Decentralized Application on Pirl Network.

We would like to thank all the participant and encourage them to not give up if they were not selected during the approval process. Take your time and prepare for the next contest.

The selected projects that will move forward into next stage ( Community Voting) are listed below in order of appearance:

1/ ZCVB project


To provide a better e-health experience to most of the world populations using Pirl Blockchain Dapp and storage.

The majority of the world population is under-served or lack adequate technology to tackle health related issues or access to adequate health system in their community due to poor or lack of technology. Most ehealth systems today are majorily private, run by corporations and patient data are silo of from the patients that need to know their health information. Internet and communications in most world community are either slow or non-existent, the decentralization nature of the blockchain would facilitate that as closer nodes or peers would improve network latency.

2/ MyPirlAdressBook

My Pirl Ethereum Address Book let’s user save a registry of names and addresses so they can easily send PIRL to their friends/family/employees etc..

The app uses metamask to make things as painless as possible.

Currently, the app is linked to a smart contract on the Ethereum Ropsten Network with plans to upload it also to the Pirl network in the future.

The app saves the data to IPFS and saves the IPFS hash on the blockchain. There are plans to include PIRL masternode storage in the future once the feature has matured.

3/ Mining Token

PoW chains represent the collaborative effort of many individuals.  Coins are used to represent a value attributed to each individual.

However, within a chain, there are many more organizational structures.  For example, groups of individuals participating in a mining pool, or a masternode network.

Often these sub-chain-groups represent their relative value using ERC20 tokens.  

Some mining pool operators on eth-like chains have developed systems to issue (or mint) ERC20 tokens in addition to the coins that are minted.  This way, the individual miner is given credit for each layer of organization they belong to – the parent chain and the subgroup, a mining pool.  There are many ways a group can use the ERC20 tokens issued to members. Voting, Token Curated Registries, staking, or trading are a few examples.  It it often easier to represent value as an ERC20 token than it is to use the base coin, as the “wrapped eth” token shows.

The proposed PIRL contest project would be to develop software modules which would integrate with open-ethereum-pool to:

– create a solidity contract on the PIRL chain to implement a mintable ERC20 token

– monitor a redis DB for payments issued to miners

– mint tokens to pool participants at approximately the same time that coin payments are sent.

– update the open-ethereum-pool web-ui to add a “Tokens” tab which would function similar to the “Payments” tab.

– update the open-ethereum-pool api to provide: token minting history, user token balance, list of “pending” tokens similar to “unmatured” coin payments

As a stretch goal, the project may seek to implement a software module that mints tokens solely based on the outgoing transactions from any address.  This contrasts to the pool example, where the redis database is used as a primary source of signals for when to mint new tokens. This stretch goal could allow for the monitoring of an address which issues masternode reward coin payments, and then signal to mint ERC20 tokens along with the coin payments.  This may drive further adoption and purchasing of masternodes, as users recognize the utility of holding tokens in addition to coins.

4/ The FABLAB and – 3D Printing


  • In the upcoming years we will see a global widespread of technologies like 3D printing and blockchain
  • 3D Printers will be used by individuals and companies to create and print items used in everydaylife.
  • Blockchain will be globally adopted to send and receive payments, create and share digital assets,certify business processes and soon.
  • Our idea is to create a 3D File Printing platform, powered by a decentralised payment and file hosting system. Everyone earn renting its 3D printer and who need to print a GCODE file can use the platform to safely pay and print it at the nearest 3D printer.
  • To accomplish that, we will use Pirl, one of the most innovative blockchain available. Pirl allows to develop a custom token (TFL Token), a smart contract to buy tokens and print 3D files stored in the storage Masternode.

5/ HODlers Club

A hodlers club is a smart contract (DApp) which lets you lock up your PIRL until a target price in USD is reached. The Dapp is designed for anyone who wishes to avoid impulse selling because of FUD. “Cowards” who leave the club before the price is reached, leave behind a small percentage of their PIRL which is shared amongst the “Mature Hodlers” (e.g. hodlers who have waited for the target price to be reached). So by joining the club, you can hodl your coins until they Moon and maybe get a few extra coins if Cowards leave.

How it Works
First someone will create a new hodlers club contract. A club will have a target price in USD, a minimum buy in in PIRL, penalty percentagefor how much PIRL is left behind by Cowards and the number of blocks until maturity.

There is or will be many hodlers clubs on this site all marked for different target prices, penalties, etc…

Other people will join the club by sending the minimum buy in to become new members. New members are called “Immature Hodlers.” Each Immature Hodler has to wait at least the number of blocks until maturity to then mark themselves as mature by clicking the “Mark as Mature” button. In fact anyone can mark anyone else as mature after the right number of blocks and its nice if club members help each other in this way.

Note: Club member can always add more coins to their initial hodlings and there is no fee to join a club.

Any member who leaves the club before the target price is reached is a Coward and leaves behind penalty percentage of their hodlings to be shared between the Mature Hodlers and the Admin.

Once the target is reached, everyone still in the club is a “Hodler” and will be able to withdraw all of the coins they put into the contract without penalty. Those that are marked mature will also share any coins left by Cowards.

6/ MicroCredentials

This is a B2C Pirl Smart Contract that allows an authorizing agent to receive micro-credential validation requests from end users. For example, in certain industries, employees are encouraged to obtain “Micro-Credentials”. A micro-credential is a small certification that indicates you have mastered a small skill. If we take K12 education, as an example:

A school district might create a micro-credentail specification for “Classroom Management” that would require the teacher to:

  • Attend 2 particular professional development classes.
  • Submit a picture of their room before and aftre the class.
  • Write a summary of how the changes impacted behavior in the classroom.

The teacher would complete these items and submit them for approval, within the district.

The glaring problem in all of this is that every district creates their own standards for what it means to obtain the “Classroom Management” micro-credential.

Fortunately, there are certain agencies within the K12 market that have are competing to establish themselves as the best-practice authority on certain microcredentials. For example, the NEA Teacher’s Union might release their own best-practice standards for “Classroom Management”. A teacher may wish to submit their district-approved Micro Credential to one of these agencies for a more pertinent review/endorsement. If approved, the teacher will have a link to a badge or a certificate that will acknowledge the completion of their micro-credential.
