Testnet deployment on Moonbase Alpha: https://moonbase.moonscan.io/address/0x70f0cec3c99103113d96ed8ad82ae6a8d9a735a0#code

Testnet Hall of Fame on Moonbase Alpha: https://moonbase.moonscan.io/address/0xb70780843be242474025f185bf26dddadfc27f43#code

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?)
• Architect the topology, research best way so all features work together
• Check and fix FE - contract integration, partially done, we need remote removals
• Add FE missing functions
• Re-architect in a way we don't need to redeploy
• Deploy version X

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.

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