A challenge to all hackers.

We're issuing a national challenge to all professionals, students and enterprises. Bring your blockchain innovation to life for a chance to transform the landscape of blockchain platforms and possibly win prizes worth up to SGD$25,000!

Objective of competition

With this hackathon, we aim to lay a brick in the interoperability effort by inviting participants to develop innovative protocols, frameworks, and use cases for blockchain interoperability.

About the organisation

The first of its kind, Singapore Blockchain Innovation Challenge is hosted by Singapore Blockchain Innovation Programme (SBIP) - a collaborative and nationwide technical community, launched from a mandate to further strengthen Singapore’s blockchain ecosystem.


Blockchain Interoperability

Problem statement

In the last few years, the blockchain space has been growing at a very fast pace. Now, there are hundreds of blockchains, both public (e.g., Bitcoin, Ethereum) and private (e.g., Hyperledger Fabric, R3 Corda), each with its own combination of consensus, communication protocols, smart contracts, and data storage technologies. However, most of the existing blockchains were designed without considering interoperability. But this is not how the real world works. Human society has interoperability at its core. Blockchain, as a tool to improve society by bringing decentralization and trust, needs to provide interoperability. As it is almost impossible to have a single blockchain system used by everyone, we need to find ways to improve current blockchains' interoperability.

This hackathon aims to lay a brick in the interoperability effort by challenging participants to develop innovative protocols, frameworks, and use cases for blockchain interoperability. The sky is the limit for this; the only requirement is to have at least two different blockchains in your project.

What is the hackathon theme?

The theme for the Singapore Blockchain Innovation Challenge 2021 is blockchain interoperability. We require projects to use at least 2 different blockchains.

This event is organised by the Singapore Blockchain Innovation Programme which is a collaborative and nationwide technical community hosted at the National University of Singapore. Visit us at to find out more!

Yes, there are no restrictions except that participants under the Enthusiast track should only use platforms, blockchains, APIs, libraries or software development kits that are available and authorized for public use.

Yes, you can start preliminary work on your hack. But to be fair to other participants, most of your hack’s source code must be written during the hackathon period.

To be eligible to register for the Corporate track, an ACRA registration number is required. The judging criteria, rules and prizes for both tracks are different. The judging criteria would be stricter for Corporate track but participating companies are allowed to use their own private APIs and can stand to win 1 year free SBIP membership.

Join our Slack channel! Look out for updates on the hackathon there.

We have mentors who may be able to help your team and we will also organise workshops on key topics as well.


I don’t have a team. Can my project for the hackathon be done solo?

No, project teams should have a minimum of two members.

We have designated a Slack channel for communication purposes amongst our hackathon participants. Feel free to find your team members via this channel. Join here.

Only the team leader needs to be a resident in Singapore. If you are an international participant, make sure to join a team with a leader who is a resident in Singapore.

Yes, but we would require you to fill up and submit a parental consent form for registration.

Registration deadline is by 3 December 2021.

No, hackathon projects has non-technical aspects too so everyone is welcome to join. In addition, you can take this hackathon as a learning opportunity to get hands-on experience with blockchain.

Yes, we welcome attendees to join us on the 4th and 18th December. Do register to receive the zoom link.

Participating in the hackathon is free. Attending the presentations, keynote and workshops on 4th and 18th December is also free.

Hackathon Workflow

What does my team need to include in the proposal?

It needs to give us an overview of what your team wants to build for the hackathon. A writeup would do.

To qualify for certificate of participation, your team needs to submit your project for the selection round held on 15th December 2021.

Both tracks are required to submit a writeup and a git repository link. The git repository should have a README for setup and other notes / instructions. For Enthusiast track, the git repository must be public whereas in Corporate track, git repository links can be private.

The judges will vet through submissions and shortlist teams for the Finale Round.

Project submission will be via Microsoft Teams.
