DCTF v0.2

The first decentralized CTF engine, used by CCTF

Deployment: TBA

Main team contributors: six, Silur, Bazsi

Hackathon contributors: SI, username, Anon, GuyFromUniversity, ZK, Metafaka team, BMEta team

Short-term ToDo

Finish the Vault
Finish the Hall of Fame with multi-management DAO style setup (approval needed for valid flag?)
Check and fix main FE - contract integration, partially done, we need remote removals
Add FE missing functions
Re-architect in a way we don't need to redeploy
Get version X ready

Workshop at Hacktivity 2023

Intro to blockchain, cryptography and learn to play CCTF. Smart contract steps:

Deploy in Remix
createContest()
Generate a priv/pub key for the flag.
addOrUpdateChallenge()
Play, find flag
register()
submitFlag()
Challenge

Workshop at HITB 2023

We will go through a fast intro to Web3 and how to hack DCTF. Anyone present at HITB 2023 Phuket, feel free to ask user six at the Crypto Village desk. Agenda:

What is blockchain/web3/other buzzwords and the tech behind?
- Consensus, RPoW, PoW, PoS
- LibP2P and nodes
- Solidity, js and rust (where and what and why?)
- Substrate
- ECDSA logic, signing, basics
Logic of DCTF
Resources for hacking DCTF
Next steps for CCTF and decentralized community

This is a free flow workshop. Six can explain these you in 20 mins, but vibes will tell how long you stay and hack.

For generating the ECDSA signatures and message hashes, use: https://git.hsbp.org/six/eth_keygen/src/branch/master/ethkeygen.py
