hack to the moon

hot & top blockchain hackathon – soon in Prague
(28-29 September 2019)

For blockchain,
no challenge is big enough

There are a lot of hackathons – but there has never been one like this in Prague. The leading blockchain firms are going to be there and we are bringing the local and foreign blockchain communities together. We will throw problems at you and it will be up to you to overcome them. At the same time, you can network and learn… And perhaps even lay the foundations of a project that will change the crypto world a bit.

And BTW – the event will be followed by the Hackers Congress. ;)

This is who we are And we are expecting you

What will we hack?

The assignment from TOP Network

What is TOP Network?


The TOP Chain PoS consensus network utilizes three different types of nodes: Edge Nodes, Validator Nodes, and Advanced Nodes. Only Advanced Nodes require votes from token holders to become active. For the sake of the Hackathon, consider the voting scheme to be 1 TOP = 1 vote (this will not quite be the case for our mainnet)

Using smart-contracts, devise a secure way for voters to delegate their voting power to a proxy, without actually transferring tokens to the proxy. The proxy smart-contract will allow another agent to vote on the token holder’s behalf, and disburse the voting dividends back to the token holder. This is called a Liquid Democracy. Token holders should be able to redeem their voting rights from the smart-contract at any time.

Purpose: In a sharded system with numerous Advanced nodes, it is difficult for regular voters to select the best nodes and keep up with the constantly changing node dynamics. Voting by Proxy allows ordinary voters who are not as engaged to delegate their voting power to a professional trusted entity if they so choose, who can then select the most outstanding, deserving, and valuable nodes.

What’s needed:
– TOP Chain Smart-Contracts (Currently Supporting the Lua Language)

A demo showing how to use TOP’s SDK with Lua will be provided.

Build a p2p messaging and/or group chat DApp using TOP Chain and TOP SDK/API. The messages should be encrypted.

Hints/Possible Direction:
– Message contents can be added to transaction bodies as a memo.
– Users can be identified by their public key.

Currently, users have very little control over how their personal information is shared and used on the Internet. Build a system that allows users to take control of their digital identity. Store account information or personal data associated with a user’s Decentralized ID securely and anonymously on the blockchain. Implement an authorization system so that only the identity owner can access the data.

What’s needed:
– TOP Chain to store data
– Use TOP smart-contracts (Lua Language) to manage the process.

Use the TOP SDK/API to build something awesome! The idea should be a real use case that could theoretically garner massive adoption. Think about what is possible with scalable smart-contracts, zero fee transactions, and near instant finality.

– TOP Chain + Smart Contracts

The assignment from Matic Network

Matic sidechains allow you to build applications which can enable micropayments and not just bulk payments. Using Matic you can try to build an exciting use case like:
– A tipping widget for social media platforms: Twitter, Telegram, etc.

Patreon for Instagram: Matic plasma chain allows transactions with near-zero fees. Applications that require a lot of NFTs can freely mint NFTs on Matic and the owner’s of these NFTs can withdraw on the main chain if and when their NFTs become valuable. To put this idea into practice, we invite the participants to build a “Patreon for Instagram”. Instagram art creators will sign up using their Instagram account and all their art will be minted onto the Matic chain. Their supporters can choose to buy blockchain art to support their favorite artists! After a sale happens, the buyer can move the NFT to the main chain if they desire.

If you have ideas of your own, That’s even better!
Use Matic Network to deploy some cool hacks and your ingenuity will be rewarded! No restrictions, Just build some cool hacks that leverage Matic Network with a proper use-case, and you can win!

Technical information:
For the sake of newcomers to the ecosystem let’s first review:


Matic’s getting started page will provide you the information needed to start building on Matic. In case of any doubts please join the group to get your queries answered:



Extremely experienced mentors will be available to you nonstop.

For whom are we doing this?

For hackers. For blockchain enthusiasts, whether advanced or beginners, who want to get high-quality mentoring, push their skills forward and get more involved in the community and discover its possibilities.

How will it happen?

We will post the topics at the beginning of September, so there will be time to prepare.
We will then see you at the venue on Saturday morning. We will again present the topics, etc., go over a few organisational matters, put the teams together and get started.

How will it be with staying overnight?

You really want to sleep?
Well, OK – help yourself at the venue.
There will be a quiet zone available together with some blankets, but ideally bring your own sleeping bag.
