Part 1 

The opportunity 

The Status Quo 

Remember the old days when centralized founding teams got funded from a selected

group of investors, and together with a static workforce created services only they

control? The intention was always to sell these services to their target market. In this

traditional model, the ‘community’ was the target market, the single source of

revenue, and it was definitely not an extension of the company.

Fast forward to 2000 , entrepreneurs, researchers and marketeers realised that the 1

concept of co-creation, the joint creation of value by company and customer,

allowing the customer to co-construct the service experience to suit their context,

would give a huge competitive advantage. Strangely enough, co-creation never really

took off, until the crypto enthusiasts started supporting Token Sales in the form of

ICO’s and sparking the community driven projects and hence placing co-creation on

the map as the new normal.

Living the new normal: community driven companies 

Blockchain and ICO’s gave birth to a new way of building companies that depend

heavily on co-creation. These companies are creating services that depend on

modeling and growing token economies, and the only source of revenue will (mostly)

be the increased value of their tokens when their economy becomes successful.

This means that success is very much dependent on building a thriving, active and

involved community. Without a community, there is no economy. And without an

economy, there is no success.

1 https://hbr.org/2000/01/co-opting-customer-competence

3

It is therefore near impossible for these companies to build success by themselves.

Their role is to spark vision and give direction to their community. And together with

the community they achieve their goals: a thriving decentralised economy and a

successful decentralized service. This means that building a community, and the

process of co-creation, has now become a core activity of every blockchain company.

The proof is evident. The first steps these companies take, often months before their

idea is even finalized, is to start a Slack, Discord, Telegram or Riot to facilitate their

community. Community involvement results in enthusiasm, word-of-mouth

referrals, and community growth. People want to help out, they become ambassadors

for the company and get others on board. The company now actively starts

facilitating co-creation by launching proof-of-care and bounty campaigns. And the

community has become a dynamic workforce that helps develop the company.

The opportunity 

This massive transformation, from ‘customers as buyers’ to ‘customers as

ambassadors’ and the ‘co-creation mentality’ is impressive. In 2017, the number of

ICO’s increased by 1781%, raising a total amount of 6037.7 million USD . And since 2

then the number just keeps rising.

Although this growth is impressive, the market potential for Crew is much bigger.

Within a decade, according to a research by Upwork and the Freelance Union, 50% of

the American workforce will be freelancers , and that is happening all in the western 3

world . This means that the workforces of the majority of companies will be 45

dynamic. And that means that companies will need to create pools of flexible workers

to keep accomplishing their goals.

To address this shift, building thriving communities to attract talent will be a core to

companies and the reason Why we started Crew.

We help companies to incentivise, use and reward the skills, influence and

knowledge of their community members, so they can focus on building what they are

good at: their economy, service or product.

   

5

Part II 

The business case As with most transformations, we see

opportunities and challenges. Crew

focuses on addressing the challenges to

lower the barriers for vibrant and

thriving communities to come together

and co-create. Innovative Projects have

the tools to further develop product

and services offered in the Blockchain

ecosystem.

Challenge #1  

Missing incentives to help 

co-create 

Within a customer base or community

there will be diverse contributors who

could be involved in co-creation.

There will be designers, developers,

thought leaders, marketeers, scientists

and people with amazing connections

that could help a company grow faster

or a service develop into something

amazing.

But how do we incentivise to

co-create? For the company this is

self-evident, they constantly invest in

their vision for the future. But the

immediate value for the co-creator is

often not very clear. Why would you

spend time on fixing a code issue, or

helping writing a blogpost, if you only

get a future reward to do so?

Crew’s solution

With Crew you can create blockchain

powered contracts for tasks that fuel

co-creation. When someone from your

customer base or community performs

that tasks, they instantly get paid.

Think about rewarding bounties,

proof-of-care submissions, opening a

network connection, code submissions,

gamification, leaderboards, contests or

even creating something tactile like a

3d printed model.

Challenge #2 

Dynamic work relations are 

risky by nature 

Co-creation means having dynamic

relations between the company and the

person performing a task. But dynamic

relationships come with risk for both

parties.

Liquidity and payment reputation

6

For the person performing the task,

the liquidity of the company is an

uncertainty, and as such its payment

reputation. It might take weeks or even

months before you get paid, or worse,

the lack of liquidity might even result

in not getting paid at all. A company’s

reputation is almost always not

transparent and as such relationships

are entered on mutual trust. A

company might pay one worker on

time, while treating other workers in a

completely different matter. For a task

performer it’s hard to find out the true

behavior and reputation. This

uncertainty reduces the will to start

performing the task, or makes starting

the task slow and cumbersome as a lot

of paperwork is involved.

None-portable reputation

For the company, the reputation and

skillset of the person performing the

task is an uncertainty as these are

currently build up and stored on

centralised platforms like LinkedIn,

Upwork, etc. Someone might build a

reputation on one platform, but that

reputation is literally non-existent on

another. A person misbehaving on for

example Upwork, can start anew on

another site without that community

knowing about the bad reputation. So

how can you be sure that the person

you hire can actually perform the task?

Crew’s solution

Crew eliminates these risks by

registering reputation, skillsets and the

task on the blockchain. Within Crew,

everyone builds up a reputation, and

that reputation influences the staking

conditions under which tasks can be

performed for all parties involved. And

in case of a dispute, community

members can vote on-chain on the

truthfulness of the dispute. Learn more

in the next chapters how Crew works

and Reputation.

This powers a new confident workforce

with dynamic and trusted relations

between companies and co-creators,

without the cost overhead and setup

time.

Challenge #3 

Dynamic work relations are 

expensive 

Traditional employment relationships

are expensive and the process is

cumbersome to set up and run. Payroll

7

providers are simply too expensive and

slow to facilitate a dynamic workforce.

Added to this, globalization and the

power to source contributors around

the world poses other challenges with

cross-currency payments, languages

and time zones. This limits the will to

employ a dynamic workforce.

Crew facilitates direct relationships

between the company and co-creator

by moving these relations to the

blockchain. Costs of payroll providers,

contracts, and the payment processing

are all greatly reduced. Crew makes

rewarding people guaranteed, fast and

cheap.

Challenge #4 

Fraud is hard to prevent 

Rewarding people for performed tasks

is the basis of co-creation. Value is

exchanged for added value. Rewards

are given for good behavior.

Unfortunately these value exchanges

are almost always done via centralized

institutions that function as black

boxes and define the rules of how we

exchange that value. This gives these

institutions power to change the rules

at will, create monopolies, charge

increasingly higher fees, sell our data

and makes the exchange susceptible to

fraud.

This black-box nature results in

uncertainties and often vulnerability.

Currently, very primitive tools (i.e.

excel spreadsheets) are being

deployed to leaderboards or reputation

assignment to customers. This open a

new question around transparency and

fairness. How do we know for certain

that the company is not favouring

other people? Or perhaps the person

responsible just made a mistake. This

dilemma becomes even more impactful

when money is involved.

Crew’s solution

Crew solves this by moving the

exchange of value to blockchain. The

truth is now decentralised, making it

transparent for everyone involved in

co-creation what is going on, and

drastically decreasing chance of fraud

through transparency and

immutability of records.

8

Challenge #5 

Governance is lacking 

In the process of co-creating a product

or service with your customers, there is

no easy way to implement governance.

Governance is an essential part of this

process to maintain a fair decision

making process while fostering and

retaining the knowledge of your

community.

Crew’s solution

Now that we have blockchain it is easy

to implement governance. Crew gives

its token holders voting rights, and

votes can easily be cast through the

Crew platform. One such example is

voting on disputes. When someone

opens a dispute for a task, community

members can vote on the outcome of

the dispute.

Companies can now really use the

wisdom of their crowd to move faster

through community driven innovation,

knowledge and expertise.

Challenge #6 

Management is time consuming 

Leveraging the power of communities

that have been transformed into

dynamic workforces includes keeping

track of progress, deliverables and

payments. This process is not only

expensive as explained before, but also

very time consuming. Companies often

use complicated excel sheets to keep

track of progress of bounties and other

tasks. For small communities this is

could be to a certain extent doable, but

for large communities (i.e. tens of

thousands of members) keeping track

and reporting ramps up the

administrative workload.

Crew’s solution

Crew makes this much faster by

integrating all community activities in

a single platform, and automatically

keeping track of thousand of

community activities on multiple

platforms. Reporting, scoring and

progress are all instantly viewable,

saving a huge amount of time.

----

We believe that these 6 challenges, and

with that the solutions that Crew

brings, will make it possible for

companies to transform communities

to risk-free dynamic workforces. In the

next chapter we present the Crew

9

dApp, after which we go into more

depth into the Crew protocol to explain

how Crew accomplishes its claims.

10

Part III  

Crew 

What is Crew 

Crew consists of a decentralised application (dApp) that companies can use to

manage their communities. The dApp is powered by the Crew protocol that is

running on Ethereum smart contracts. The protocol is open-source and can be used

to integrate Crew functionality in any application. The Crew team will build and

develop the protocol and the Crew dApp.

The dApp 

The Crew app has been in development since 2016 as PostSpeaker. 100s of customers

are using the app for publishing content to the social media of their community

members. We are currently extending the app to run on the decentralised Crew

smart contract protocol, and to integrate features that make use of that protocol. See

the roadmap for detailed information.

11

The Crew dApp enables companies to:

● Create a transparent record of reputation

Payment, task handling and dispute behavior is all tracked as a reputation

score in the CrewId contract.

● Recruit community members in a simple and fast way via email,

and automated via Slack, Telegram and Discord.

Send invite links through email, and direct signup within Slack, Telegram and

Discord through bots.

● Create paid tasks

Easily create tasks and bounties and target based on community member’s

competences.

● Increase promotional reach

Use Facebook, LinkedIn, Twitter, Instagram of community members to

promote content in a fully automated and secure way. Push that content as

well to Slack, Telegram, Discord in a fully automated way.

● Reward community members

Reward community members for promotions on these platforms through

automated micro-payments.

● Setup and run automated loyalty campaigns

Automatically reward community members with micro-payments for showing

certain behavior. For example, reward people who posted on Slack 50 times.

● Create transparent leaderboards

As all tasks and rewards are tracked on the blockchain, leaderboards will be

12

immutable and transparent.

● File disputes on tasks

In case of a dispute, the company or the task performer can open a vote. The

votes are publicly available on the ‘dispute board’. Other users can vote by

staking tokens. The users who voted correctly will earn the tokens of the users

who voted incorrectly, as well as the tokens staked by the company and the

task performer.

● Cast votes and polls

Build-in governance enables companies to case polls and votes to use the

knowledge and expertise of their community

The Crew dApp enables community members to:

- Create a portable CrewID that holds skillset and reputation

The CrewID is a personal ID that can be used in different communities within

the Crew ecosystem.

- Find tasks and earn CRW tokens for performing these tasks

The community’s task board lists tasks that the user can pick up and perform

in a permissionless way.

- Review tasks of other members and earn CRW tokens for correctly

reviewing these tasks

Tasks can have a reviewer who judges the deliverables of the tasks. Accurately

reviewing tasks earns you tokens and reputation.

- Earn CRW tokens by vouching for users with low reputation.

Users with low reputation can only pick up tasks if other people vouch for

them by staking tokens. When the task is delivered as agreed, vouching users

earn tokens.

13

- Vote on disputes and earn CRW tokens by voting on the

correctness of the dispute

In case of a dispute, the company or the task performer can open a vote. The

votes are publicly available on the ‘dispute board’. Other users can vote by

staking tokens. The users who voted correctly will earn the tokens of the users

who voted incorrectly, as well as the tokens staked by the company and the

task performer.

- Suggest tasks

Co-creation means community members can suggest tasks. The company is

free to accept or reject such tasks.

 

Our vision for adoption 

The UX patterns in blockchain are currently too complicated for mass adoption. We

plan our dapp to be simple in use by abstracting away blockchain as much as

possible. A good example is the Giveth dApp, which our team members have helped

building.

How Crew works 

A simple use case

Acme Inc wants to use the Crew protocol for rewarding someone for a task that helps

co-create their larger vision. The first step is that Acme deploys a Crew Task Contract

and stakes:

● The reward for the performer of the task in Ether or in any ERC20 token

● A stake in CRW tokens based on their reputation. This stake functions as a

safeguard for the task performer, for example when the company cancels the

task.

14

Jane from the community now wants to perform the task. Jane stakes some CRW

(amount based on her reputation) in the Crew Task Contract, to assign the task to

her. She needs to stake to claim the task and to show she’s serious about performing

it.

Once she delivers the task and it is accepted, both parties need to review each other.

This will update their reputation. After reviewing, both parties get their stake back

and Jane gets her reward.

This scenario is just a simple happy flow scenario, the real world is much more

complex. The next example shows how to handle more complex scenarios.

The reviewer

Delivered work is often subject to subjective approval and opinions. To make sure

that all parties involved are happy, and the reduce the chance for disputes, a reviewer

can be assigned to a task.

A reviewer is basically an ethereum address, which can be a single person, a multi-sig

or any other smart contract, an AI, an Oracle, etc.

In the case of using a reviewer, let’s say this person is called John, the company

assigns John as reviewer when creating the task. Now, when Jane delivers the task,

John needs to approve it, or provide feedback how to improve the task. This feedback

loop is performed off-chain, but state changes (as in ‘needs improvement’ ->

‘delivered’) are stored within the contract for transparency.

Once the work is accepted by the reviewer, Jane, John and the company get their

stake back, and John earns a review fee in CRW which is deducted 50-50% from

Jane’s and the company’s stake.

Reputation and skillset

15

When you create a task as a company you don’t want a plumber picking up a task for

a developer. And you might not want a junior developer working on a task that needs

experience. With Crew you can control which tasks can be picked up by whom, by

specifying minimum required reputation within a certain skillset.

When this behavior is required you can specify skills and required reputation for

those skills upon creating the task. Let’s say the parameters are like this:

● Skillset: developer

● Minimum reputation: 4 (on a scale from 1-10)

Now we have Dave, a developer who just entered the community and started with a

reputation of 1. Dave will be unable to pick up this task, the contract will simply

reject him. But there’s also Sara, an experienced developer who has a reputation of 8.

She can easily pick up the task and she even needs to stake less CRW because her

reputation is very high.

Reputation plays an important role within the Crew protocol. It function as a

matchmaking mechanism between task owners and task performers. But it also

influences stakes required to take action within the protocol by all parties. In the next

section we explain in great detail how reputation works, and also how dispute

Disputes

These examples present happy flows, but sooner or later there will be disputes

between task performer and the task owner, even when a reviewer is involved.

With Crew, both task performer and task owner can open a dispute. One of them

need to file a case with evidence and proof by staking an amount of Crew. The other

one can add his evidence. This case is stored on IPFS.

All disputes are presented on the dispute board for a given community. Anyone can

check out the disputes and vote by staking on the truthfulness of the dispute. Once

16

the vote closes, the winners earn the stakes of the losers. The stake of the dispute

opener goes to the other party. For example if the task performer opens the dispute,

and he loses, his stake goes to the other party.

Reputation 

The protocol keeps track of reputation by storing data like review time, task

completion time, satisfaction rating on chain. This data is made available through the

Crew oracle.

Calculating reputation

Reputation follows a log base 10 mathematical function going up, and an inverse

log-10 function going down. This means that it is relatively easy to increase your

reputation, but it gets harder and harder to keep increasing it. On the other hand,

high reputations drop very fast but low reputations drop slow as it should be

expected that a member with high reputation delivers quality work and doesn’t make

mistakes as often as a low reputation member.

The log base 10 function also means that a person with reputation 50 has a ten times

higher reputation than a person with reputation 49.

17

Another characteristic of Crew’s reputation system is that people with low reputation

cannot harm people with high reputation. They can only add reputation. This only

counts within a specific role, so a reviewer with low reputation can influence the high

reputation of the task performer or the company.

All reputation decays over time as it is only calculating the activity within the last

20000 blocks (roughly 6 months), and in that calculation the older reputation

ratings are decayed exponentially, so that more recent ratings have more influence.

Reputation is stored within a CrewId, and is only updated when it gets queried.

Increasing reputation

Within the Crew protocol there are a couple of ways you can increase your reputation

1. Perform and deliver tasks according to the specifications

2. Submit proof of past accomplishments for community review (certified trust)

3. Have other people stake in your reputation (witnesses)

18

We will now give an overview of these 3 mechanisms

Perform and deliver tasks according to the specifications

After performing a task, the company and the reviewer need to score the quality of

work. The options are:

0 = did not deliver

2 = delivered, but incomplete

4 = delivered, but rejected

8 = delivered, but needs improvement

16 = delivered according to agreement

32 = exceptional work

Submit proof of past accomplishments for community review

A user can increase reputation by submitting proof of past performances and request

review by the community. To do so, a user submits a url or file containing the proof,

stakes an amount of Crew as the reward for verification. This request is then

displayed on a marketplace.

Other users can then review and bet on the outcome of the proof, basically

answering the question if the proof is truthful or not. They do so by staking 20% of

the reward. Once the vote closes, the winners get all the stakes, the reward and an

increase in reputation. The losers lose their stake to the winners and decrease their

reputation. The user requesting proof always loses his stake, he basically pays for the

review.

Have other people stake in your reputation

A user can ask other people to stake in their reputation. This doesn’t really increase

the reputation of the user, but it does allow him to pick up or review tasks that

require higher reputation than he currently has, by staking less CRW than he should

19

based on reputation. This enables the user to do more tasks and increase reputation

faster.

Information stored

Whenever a task is performed, the following metrics are stored on IPFS for all the

parties involved in the task:

1. Time of task completion and if that time was in the agreed timeframe

2. Time of review completion and if that review was in the agreed timeframe

3. Amount of reviews tx the task needed to be completed

4. Task cancel request and which party requested the cancellation of the task.

5. Subjective score 0-5 from for each party in the contract, given by the other

parties.

Staking

The amount required to stake within the Crew protocol is based on reputation and

the CRW-fiat exchange rate. The base stake is the inverse log10 mathematical

function of the reputation score. So if a user has low reputation, he needs to stake a

lot. If a user has high reputation, the stake is low. We call this the ‘reputation

multiplier’.

The protocol has predefined the stakes, which can be updated by the community

through governance. These are:

- The base stake for tasks is defined as 10% the price of the fiat task reward

times the ‘reputation multiplier’

- Staking for vouching for other users is defined by the reputation score

difference times the ‘reputation multiplier’

 

Reputation scoring protocol changes

20

The reputation system as presented here will be implemented upon launch. However,

we implement governance with voting mechanisms so that the community can

decide to change the mechanism or parts thereof in the future.

Crew will be built on top of Aragon, so these governance and voting mechanisms will

adhere to Aragon’s standards.

21

The CRW Token 

The aim of the Crew protocol is to

incentivise people to pick up and

perform tasks and deliver these tasks

as per the mutual agreement, reducing

risk for all parties. As such the protocol

discourages cheating and bad

behavior, and encourages delivering

high quality work within an agreed

timeframe. Furthermore the Crew

protocol functions as a matchmaking

between task owners, reviewers and

task performers.

As such the CRW token is both the

currency, reputation vouching and

governance mechanism within the

protocol. All users using Crew need to

stake CRW based on their reputation.

This stake functions as a fine for bad

behavior and is returned in case of

good behavior. A high reputation score

results in having to stake less CRW, a

low reputation score results in having

to stake more CRW. This makes sure

that it becomes easier for people with

high reputation to pick up and be

accepted for tasks. But if such person

abuses its reputation then the next

time the stake will be higher as

reputation went down.

Users, including the oracles and

reviewers, get paid in CRW for tasks

22

performed, apart from the currency as

defined in tasks as the reward.

The Crew token is an ERC20

compatible Ethereum token that is

accepted by all Ethereum wallets. The

Crew token is required to use the Crew

protocol and represents a value of

work within Crew. Every transaction

within Crew is performed with the

Crew token, on the Ethereum

blockchain. This enables a safe, secure

and transparent protocol.

   

23

Part IV 

Architectural overview 

 

The Crew protocol consists of a set of Ethereum smart contracts:

● A CrewID contract that holds user records. For each user it includes

reputation, hashed userdata and skillsets of all parties involved in the Crew

protocol.

● A Crew Task Contract that is being deployed for each task.

● The Crew Protocol Contract that holds the reputation model as well as a

record of CrewIds

24

● An extendable Crew Proof of Authority Oracle that initially provides

fiat-to-Crew rates to the protocol contract but will later support other data,

like social media proof and web content publishing proof.

 

CrewID Contract 

The CrewID contract keeps a user record that consists of:

- Reputation per skillset as calculated by the protocol.

The user can add skills to his CrewID but they’ll start with a reputation of 0.

- User information like Twitter handle, email. This information is stored

encrypted in the contract and is controlled by the user.

To participate in the Crew network, a user needs to deploy a CrewID contract. Upon

creation the CrewID is registered with the protocol contract. Afterwards, the user can

25

update and selectively share his information, but only the Crew protocol can update

reputation.

 

Crew Task Contract 

Creating a task

Upon creation of a task, the owner sets:

● The reward

● The required skill(s)

● The minimum required reputation for each skill

● A reviewer address

● A link to an IPFS record holding the details of the task

Match-making, or how a crewId can pick up a task

A person can only perform the task if there’s a match between the task’s skills and

reputation and the person’s CrewID as explained in How Crew Works.

26

The assign() function is called on the task contract with the reputation and skills of

the CrewID. If there’s a match between required reputation and skills, the task

contract will call getRequiredStake() on the Crew Protocol contract. The Crew

protocol contract now calculates the required stake, and calls the payStake()

function on the CrewId to initiate payment of the stake. If the CrewId does not have

enough balance, the transaction will fail and the CrewId cannot assign the task.

Paying out a task

As reputation is such an important part of Crew, a task is only paid after a participant

reviews all the other participants. For example, the owner needs to score the reviewer

and the performer on a scale of 1-10, by calling the submitReview() function on the

protocol. Upon receiving the review, protocol will initiate the payment of the

completed task to the msg.sender.

Crew protocol contract 

The protocol contract is a singleton contract that holds:

● the reputation model

27

● a record of all CrewIDs and their associated tasks

● a record of available skillsets

● A record of all tasks

The reason the contract is a singleton is to make sure CrewId is portable among the

many organisations using the Crew protocol. Upgradeability is achieved by moving

all the logic to a separate reputation model contract.

Reputation model contract

The reputation model is stored in a separate contract to ensure upgradability of the

model.

Crew POA Oracle 

The Crew Protocol is powered by an off-chain Crew POA Oracle to initially provide

social media publishing proof. The role of the oracle is to give this input to tasks that

depend on social media api input . Smart contracts cannot make external calls to

third party service, they can only receive input.

That means that an intermediary service, an oracle, needs to fetch requested data

from trusted and verified 3rd party service, and pass it on to the smart contract. The

challenge is that money is involved, so the data provided by both the 3rd party and

the oracle needs to be untampered, secure and trusted.

28

Crew solves this by setting up an off-chain proof of authority oracle. Initially we will

select 10 trusted parties (authorities) to run a Crew Oracle node. These 10 nodes are

required for consensus, but also for handling fall-outs of availability. All nodes can be

monitored by the public and the code will be open-source for transparency. The 10

nodes will need to stake a significant amount of Crew in the Crew Oracle contract.

The crew oracles nodes will receive social media result requests from the Crew Oracle

Contract. These requests are encrypted with a public key provided by the Crew, and

only Crew holds the private key.

All 10 parties query the respective social media (e.g. Twitter, Facebook, etc) and pass

their answer back to the on-chain Crew Oracle contract. This answer is again

encrypted with the public key provided by Crew.

29

Additionally the answers are also stored on IPFS for transparency, unless the data is

marked as being sensitive. In that case the data can be encrypted so that it is only

viewable to the parties involved in the specific task contract.

Once the oracle contract receives the answer, a consensus mechanism is triggered:

A. The nodes that lie loose part of their stake to the nodes that don’t lie. When a

node lost all of their stake, they will not be trusted anymore and be replaced

by another trusted party.

B. The nodes that tell the truth will receive a reward in Crew, as each oracle

request requires a fee.

The consensus will be supplied to the task contract as the true answer, upon which

contract logic will be executed.

Initially the Crew Oracle will only supply social media proof, but we will extend it

with other data sources, like Crew-fiat exchange rates and web content publishing

proof.

Part V 

Go to market strategy 

Phase 1 - Grow Crew 

Our initial focus is to use our own protocol to kickstart Crew. We are going to involve

our community and reward any tasks performed by our community in a transparent

way via the Crew protocol. We will build a dApp on top of the Crew protocol to

handle task submissions, bounties and run ambassador programs.

Phase 2 - Crypto roll-out 

Our second focus is the crypto space. Crypto companies greatly depend on thriving

and involved communities. As explained in the first chapter, there’s a huge shift

happening from ‘communities as buyers’ to ‘communities as ambassadors’ and the

‘doing it together mentality’. We are going to enable crypto companies to easily run

extensive bounty programs and proof-of-care applications in a transparent way using

Crew, by extending the Dapp we developed in the initial stage.

Phase 3 - Partnerships 

Our third focus is to get non crypto products and services on board by building

integration partnerships. In the footsteps of crypto companies, there will be a

massive interest and shift towards blockchain technology. We believe that traditional

companies will want to involve their communities more and more in the near future,

and moving to Crew saves costs and makes everything more transparent. Those

companies include providers of loyalty programs, ambassador tools, gamification,

behavior analyses and analytics.

Phase 4 - Foundation 

Our final focus is to run Crew in a completely decentralised way. We certainly do not

want to replace the centralized institution that control rewards. We will give Crew

31

token holders governance rights to have influence on the direction of the project. And

it might even be possible that Crew will become a foundation in the future.

We believe this plan of attack is what will make Crew go to the moon. It will become

the defacto standard for incentivising communities via blockchain technology. And it

will create a more transparent and decentralized future for the basis of our economy.

For a detailed roadmap please check the Roadmap section.

Business model 

The Crew protocol is open source and can be implemented by anyone. This means

that other people can create different business models using the protocol. As such,

within the protocol we build an option to charge a fee for payouts taking place

through the protocol. It’s up to people implementing the protocol to use that fee or

not.

The Crew team will be implementing this fee and it is set as a margin of 0.25%. That

means that 0.25% of each payment goes to the Crew core team, which is still very

much lower than any payment processor out there.

Our dApp will also charge communities according to a SaaS model on a monthly

basis, based on the amount of community members served through the dApp.
