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:

1. Deploy in Remix
2. createContest()
3. Generate a priv/pub key for the flag.
4. addOrUpdateChallenge()
5. Play, find flag
6. register()
7. submitFlag()
8. 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.
