<u>Introduction</u>

This project is a part of another project that develops a smart contract based hiring platform on Cardano called Bworks.

In this challenge we focus to create a tool that helps Cardano developers have right paid jobs in the context of the Catalyst project and beyond.

By this way the project will direct map developer's income to their abilities, guide them the right way to grow by providing specific, actionable data that will lead to growth of Cardano developer resources, let them love & focus work more.

Additionally, this also leverages everyone technical or non-technical to become a proposer with available on demand resources. This also leads to an awesome picture.

<u>An example</u>

Someone is a non-technical person he got fund from Catalyst and wish to have a developer to fulfill their project:

• He doesn't even know how to check if a developer is capable of working out the project so freelancer.com and linkedin.com are not a choice.
• He wishes to make sure the money is paid only when the product is built and delivered*.*

Also there is a developer who is capable to work out project but:

• He doesn't have linkedIn or resume, he needs a job with less time for interviews, submitting a resume, and code challenges.
• He wants to make sure his work is paid 100% even in cross countries before he starts to work.

bWorks is to solve above problems, proposer then has product delivered*,* never lose money for uncompleted work & developer has money for their work, the payment is always committed by smart contract*.*

<u>Features</u>

• High Accuracy of job suggestions for developers and bid suggestions for proposers.
• Seamless service that covers all aspects of a freelance hiring process.
• Payment and product delivery are protected by Cardano Escrow smart contract.
• No Bias feature meant the selection only depended on ability to carry out a posted job.
• Users have to verify its ADA wallet which is used for all payment transactions in bWorks.

<u>Functions</u>

• Post job for proposers.
• Suggest matched JOBs and place a BID for job developers.
• Suggest matched BIDs and select a right BID for proposers.
• Call the deployed smart contract to handle freelance agreed terms.
• Manage the progress until end by smart contract:
• In case a developer gets a posted job done the money is transferred to the developer account.
• In case the developer fails to get a posted job done the money is returned to the proposer account.
• Provide developers insightful and actionable reports to grow their abilities ahead in the future in terms of countable income.

Extra functions:

• Task management.
• Loyalty and reward programs.
• Developer grouping to bid or to split a task.
• Code quality ranking.

<u>Architecture & main modules</u>

bWorks contains off-chain code runs on AWS infrastructure and on-chain code runs on Cardano blockchain network. The architecture include backend REST APIs, 03 web frontend apps, 02 smartphone apps and the deployed smart contract on Cardano:

• Backend REST APIs & smart contract off-chain code.
• The deployed smart contracts on Cardano blockchain network.
• Frontend apps for:
• Employer
• Job seeker
• Admin
• Mobile apps for proposers and developers.

Project tech stack: NodeJs, React and React native, MongoDb, Redis, Plutus and MarloweJs

<u>Impacts for proposers, developers:</u>

• Everyone can become a proposer for their owned ideas then hire freelancers through bWork.
• Any developer can find paid jobs by their abilities with suggested jobs via bWork.
• Remove all concerns about job done and payment for proposer and developer.

By this way we will help developers focus on work, increase their income and grow their ability. It directly unblock developer's potential and attract more capable engineers to join Cardano.

<u>Align challenge KPIs</u>

• By solving the deep concerns of developers, increasing their confidence and excitement about Cardano, this project will lead to growth of Cardano developer resources, unblock Cardano's potential by transforming more ideas to products.

• From a proposer perspective the project also backed them with on-demand resources that leverage them to spark more ideas.

• Since most blockchain projects are open source the more project success the more open source libraries and frameworks came out. This solved exactly the KPIs of challenge especially with creating more open source tools, libraries, framework and growing Cardano developer resources in terms of quantity and abilities.

<u>Communication & marketing</u>

• This project intends to apply to Catalyst so the communication and promoting should move through communities and mostly by product itself.

• Once people benefited through bWorks e.g developers increase their income, non technical people can be an author of an open source library. This is the best way that product is communicated out and marketed.

There are still some risks that might block the move of project into success, these risks need to address out in advance and have solution to solve. this strengthen team's confidence moving forward.

List of saw risks & corresponding response to solve:

• Risk: Lack of Cardano smart contract resources for developers e.g documents, libraries.

Solution: spend more resources to research, prototype in advance to select the right development strategy.

• Risk: The limitation of current smart contract capacities to execute the complex payment model e.g split one smart contract into sub-smart contracts.

Solution: have reasonable expectations at this time, find a solution with off-chain code.

• Risk: The limitation funded budget lead to limit of resources to fulfill project.

Solution: prioritize to use internal resources from primary members, have reasonable expectation, narrow down additional works.

• Risk: The difficulty to have real data set big enough to practice the accuracy of matching algorithm.

Solution: generate lab dataset to simulate the near real life data set.

• Risk: The high expectations of users for a new application make lose team's excitement

Solution: focus on what really matters.

There might be some other risks may happen during development period, but they are not critical enough to block the move.

Q1-2023

Beta release and go to market

Select 10 Catalyst proposers to invite as employer user, 10 Cardano developer to invite as job seeker as pilot users to try product and give feedback:

• How post job and select bid functions work for proposer
• How job selection and bid functions work for developers.
• How the smart contract handles the negotiated terms and can it make sure posted job is done for proposer and money is transferred to developer only when posted job is done.

Once we have good feedback from pilot users it is time to publish product marketing to a massive number of users, groups.

The cost to complete this project include cost to complete 03 main end user applications for different type of users (developer, employer/proposer & administrators), smart contract off-chain & on-chain code and other core common components e.g search, fetch libraries.

Please describe how you will measure the progress and the development of the project?

The progress and development process are measured and tracked by the number of "DONE" tasks & "DONE" groups of required tasks which define other large work or software functions. These "DONE" tasks & "DONE" group of required tasks meant software functions are developed & tested, and works are completed.

<u>Clear and trackable development progress</u>

• Use TDD method for development process.
• Project will break down into small tasks then assigned to each member via Redmine (a project management software).
• Write UNIT test code in advance before developers start product development.
• The task is confirmed to be completed only when the UNIT test result “PASSED”.
• Use Github auto deploy to push the latest code to the staging server to make the development product be available to everyone.
• Weekly report that lets everyone be aware of the whole process.

<u>Quantitative indicators for development process:</u>

• The number of task/function “PASSED” unit test code.
• The number of benchmark and QC tests “PASSED” for end user functions.
• The number of gitHub commits and merges.
• The number of tasks gets “DONE” in redMine.

<u>The development success consideration </u>

• 100% main tasks are "done"
• 100% unit test for main task is "passed"

By this way the progress is clear, measured and tracked.

Please see detail at breakdown tasks success KPIs or our present at the attached link.

<u>The definition of success for this project from product development points of view</u>

• Main software components are developed and tested: 100%
• Extra aspects & extra software components are developed and tested: 70%-100%
• System operations KPIs: 70%-100%
• Product is published and available to users: 100%
• Extra factors of product delivery: 70%-100%

<u>The definition of success for this project from business points of view </u>

• Application has a large number of submitted & DAU users.
• Application becomes a popular, trusted services for developers to have paid jobs.
• Developers like to use reports from bWorks to grow their abilities to adapt job market.
• Large number of Cardano developers are growth through the application.
• Large Number of projects are developed through the application lead to a large number of open source libraries and framework.
• Number of submitted and DAU users: we expect to attract around 60% of catalyst users, 40% of other Cardano users and around 100k external users total 200-500k will be Bworks users in first year after release: 80%-100%
• Rate of user that satisfied with service from product: 70%

To meet above goals we must accomplish the below success KPIs across development and delivery phases:

Success KPIs of main software components development

• The accomplishment of function and component development: functions, components, scripts are developed and tested in terms of quantity and functionality: 100% they are developed and tested.

e.g: UI for proposer to post job, UI for developer to bid job, the smart contract is executed as expected.

• The accomplishment of full product development: all sub-components are developed and tested. Full application is formed, tested and meets designs: 100%, e.g product on staging server is available for:
• Proposer to post a job
• Developer to bid a job
• Smart contract runs smoothly to manage developer progress until developer gets job done and fund is transferred to its account.

Success KPIs of extra software components & aspects

• Code quality and visibility: source code is clear, easy to re-use and maintain: 80%-100%.
• <u>BI reports are valuable to users: </u>80%-100%
• <u>All code is public at registered Github link that available for other people to view, improve or re-use: </u>100%

Success KPIs of product delivery

• Product is released as scheduled timeline, available for everyone to use at public url through the internet: 100% e.g The released product will be available at: https://bworks.app
• Main functions are available for user to use: 100% - proposers and developers are able to submit an account to find resources or find jobs. Deployed smart contract then rule the rest of progress.

Success KPIs of system operation (ms is millisecond)

• System uptime: 99.9%
• <u>Basic access latency: </u>20-50ms depend on your internet connection: 100%
• <u>Post job for proposer, bid job for job seeker latency: </u>10-20 ms, realtime.
• Find a matched job for a developer latency: 10ms.
• <u>Find a matched bid for a proposer latency:</u> 10ms.
• Freelance contract terms negotiation: instanced and real time.
• Submit smart contract to Cardano blockchain network latency: 50-1000 ms depend on Cardano network.
• Security: 100% unwanted access is dropped and all data is safe.

<u>References</u>

1. Success criteria: success KPI >=70%. KPI >=70% means a task is done (function is developed & tested or work met expectations), the rest 30% used for outstanding assessments for factors that surpass success criteria. e.g a develop an API task has KPI 80% means it is DONE and code runs faster than expected.
2. The meaning of numbers in % indicate the percentage of completion of task use in success KPIs:

• 0%-70%: the task is not completed, it is 'on-working'.
• 70%-80%: task is completed & tested or work is done, good to go.
• 80%-100%: task is completed and has excellent output e.g response time faster than expected.

We expect to meet above KPIs that clearly define BWORK as a successful project.
