BSV Hackathon

3rd Bitcoin SV Hackathon

We saw amazing stuff from the first two hackathons, which were in the 48-hour format, but this time we had an 8-week long coding round and definitely saw developers put a lot more thought into what they wanted to build before they started to build.

Organized By: Bitcoin Association
Run By: nChain

Prize Pool

The competition saw more than 400 people from 75 countries compete to build a creative project on the Bitcoin SV blockchain over eight weeks. Out of 42 projects, entries were whittled down to three outstanding finalists, each with a chance to win a share of the US$ 100,000 BSV prize pool.

The final positions were determined by judges and audience vote, which Bitcoin Association Founding President Jimmy Nguyen said resulted in a close race, with all finalists receiving at least one first-place vote.a

Finalists

Kyrt

Kyrt integrates Bitcoin microtransactions with subscribable events available via Zapier – a major platform enabling easy integration workflows across more than 2000 applications. Zapier is an incredibly powerful tool and by integrating a micropayment rail into any application interaction, the possibilities are endless.

STOTASK

STOTASK is a new entrant in the ‘gig economy’ that allows owners of datasets to leverage the idle time of anyone to apply human interpretation to tag data. This is a missing link between human classification and machine learning. Classification tasks that are easy for humans but hard for machines can become machine-learned with an initial human input. Bitcoin SV is used as the payment rail for STOTASK, enabling work to be paid out in very small increments. Coupling this with Metanet data structuring in the future has huge potential.

RepZip

Identity on-chain is a fiercely discussed topic in Bitcoin SV and a key missing piece of infrastructure. Repzip not only provides a real solution to the problem, but also integrates with Paymail and existing Bitcoin data infrastructure in a way that can satisfy a plethora of use cases. Identity is powerful and is a core link between the digital and the physical world. When the solution integrates 3rd party attestation, this will become a core and central part of day to day Bitcoin interactions.

RUNNERS-UP

Sourceshare

The problem with using BSV as a backend is that all apps using BSV will need a server to scrape the OP_RETURN data. If they use other people’s servers, they won’t be able to guarantee uptime or lack of tampering (node operators have the biggest incentive to tamper). Because customers can’t see what’s going on with the developers code, they may or may not be correlating two very vital pieces of information: your BSV account and your real life identity. In 10 years, these vital tuples will be worth quite a bit to ne’er-do-wells; with this info they will set out to hunt you down if you have a big enough stack! Sourceshare aims to let BSV developers prove what code they’re running to gain trust and goodwill, and it would be a good best practice to implement ASAP.

TrueReviews

TrueReviews solves the incentive problem for online reviews. Today, there is little to no incentive to leave accurate and detailed reviews for locations, restaurants, events, and more. TrueReviews solves this problem by allowing users to be tipped for reviews that they post, but also earn rewards from businesses and other users for posting high quality reviews. TrueReviews replaces the fake internet points economy that governs other reviewing sites with a real market-based economy where users earn money for contributing high-quality content.

ScrollPay
Use small amounts of BSV, and read payable content just by scrolling.
Ask The World

Ask The World allows you to use your BSV to improve the aggregate wealth of knowledge to all those who participate in this Society. Leveraging market forces to get the answers you need, think Stack Overflow & Quora – but without the poisonous attention seeking ads. In this society there are a lot of talented people, and their time is precious. There exists an information problem when it comes to solving “where can I have the most impact in this moment”. Ask The World is a platform which allows participants to see where their expertise can be best met with real demand. Freelancers, Historians, Philosophers, and Lumberjacks can all use their BSV here. Whether it’s £200 to solve a critical malfunction, or £0.10 per person to crowd source the finding of the long lost painting: Ask The World – use your BSV and ye shall Receive.

Participants

Tape Recorder

Tape Recorder records your application as it runs on your device and stores the application execution as Bitcoin Script. Tape Recorder makes it simple and easy to use Bitcoin to record everyday activities with full attestation of code execution.

Terminus

Terminus is where human knowledge will be stored and monetized. Terminus is a Question and Answer framework where the incentive is not just prestige but money. In Terminus curiosity and knowledge are rewarded. Terminus is stored in bitcoin metanet, public to anyone forever.

The Fast Company Ecosystem

A roadmap for a BSV incubator and ecosystem. Create a tokenized smart contract model that attracts investors and makes it easy to support seedling companies.

PollSV

PollSV enables the world’s first trustless polling marketplace. PollSV is a polling system that utilizes the blockchain and a powerful incentive structure that encourages users to spend Bitcoin to vote on user created polls. Simply put, if the user votes for the winning side of a poll they receive the losing side’s contribution to the poll. Poll creators also receive a portion of the poll reward.

askSV

Our project bounties questions using BSV. Users log in with money button, ask a question, and set a bounty for the question. Other users can answer the questions. The user that submitted the question can select the best answer to receive the bounty. This can can be general questions, or very technical questions. We would hope to gain users from both the general community and the technical community.

Supply Management System

One key usage for the Blockchain is supply chain management. There have been issues with providers trying to track their shipments, and they get counterfeit, bad quality or not the original item. The countermeasure with certificates that costs millions, are easily faked and are not effective. This project is a solution to this problem, effectively:

Allowing to review the item by the author along it’s route:

  • in realtime
  • in the most secure fashion
  • with almost no cost (less than 0.01$ per tx)
  • with gps coordinate
  • immutably and verifiably on the BSV Blockchain
  • provably honest and true tx
SVPairs
SVPairs is a simple pairs card game running on the blockchain. An Oracle deals card shuffles and posts game-state updates on-chain. The user interacts with the game by posting actions on transactions. The user also pays a small fee to flip cards, when a match is found the oracle pays the user a reward instead.
MicroBSV
This application aims to build new bottom-up approaches for the social knowledge Web, which can be regarded as the collaborative result of individuals contributing their personal knowledge to a collective web.
Kabete Co-Op Management
Small-scale co-operatives in developing countries typically manage interactions with their members using log entries on small paper cards. This project aims to build an on-chain records-management system tied to mobile identity.
BitPoll

Honest polling with Bitcoin

What’s it all about?
It is hard to know if a poll is being taken with the right cross-section of audience that makes the outcome relevant to us. More and more we look to the public conensus to help guide our daily decisions, and to do this accurately and reliably is becoming increasingly more difficult.

How does BitPoll help?
BitIndex is the first Bitcoin enabled polling system that allows you to set up your own polls, and earn real money for each vote you receive. USers who are passionate about the issues will donate small micro-payments at a time, enough to attract a motivated and meaningful audience.

Benefits
Users can now browse a stream of polls that they know were paid for by the poll-owner, and then choose which ones they feel passionate enough about to commit a small micro-payment to vote. This leads to a self-moderated outcome of quality results, authenticated and decentralized, ensuring accuracy and a public option you can trust.

Enabled with economy
The great equalizer for all public services is payments. If people are motivated to pay for something, the quality of the results are massively increased. People will not pay even a small amount unless they are motivated and invested in the outcome.

Why Bitcoin?
Paying for anything is complicated. If it’s cash, you have to be there in person. If it’s online, you need to fill out credit card info. Plus, many services that are enabled through MICRO-payments are not possible with traditional payment systems. Bitcoin makes services like BitPoll possible by enabling users to both earn and transact in small, easy payments that open up whole new online economies and utilities that will benefit the world like never thought possible.

The fees
It’s simple. It costs you a $1 worth of BSV to create a poll, but you earn $3c for every vote received. If your poll is popular, you can start to calculate your earnings.”

StopPlastic.app
We are accumulating plastic everywhere and there are already a lot of alternatives. By creating projects and providing them with the support we contribute to reducing the problem of the plastic waste.
