Git Blockchain

The idea

A blockchain that works over Git.

Git already supports:

• cryptography signatures (git commit -S)
• multi approver signatures (git commit --signoff)

It’s technically possible to port the consensus workflow using basic git commands.

By adding a CI/CD bot/script, it becomes possible to have an equivalent of smart-contracts that only allows people to open pull-requests while having a robot to make the merges.

Finally, we can find about having a proof-of-stakes approach based on git contributions or something more centralized as a .forgers.txt file that defines allowed forgers.

Challenges

Find other parts of what makes a blockchain:

• how-to define/allow/deny a node to be a forger in a distributed way
• create a small utility that makes the git commands automatically
• automatically generates with the CI/CD a static blockchain explorer

Usages

No idea yet.

It can be used as a pedagogical support to learn how the blockchain works.

OSMOSE Hackathon 20/21 april, 2019

Few days ago, I organised and hosted a Hackathon at Berty.

Two days of code and startup-design with friends, a new network, new opportunities, new ideas, and a lot of fun.

Who

• Berty (me)
• Osmose (Zooma & Zaraki)
• La suite du monde (Adrien)
• Busy (Ekitcho)
• Independants (Loup, Norman)

Topics

• Projects presentations
• Discuss about “how to work together”
• Focus on code

What we’ve done

• Meet people
  • New friends
  • New colleagues ? :)
• Refactor if the web radio of Osmose / La suite du monde
  • Using with Liquidsoap, Docker, Icecast, Golang
  • Plan to plug it with Discord / Telegram to interact with users
• Automate “La suite du monde” processes (onboarding, federation, delegation, scouting, etc…)
  • With Airtable, Zapier, custom scripts
  • Leboncoin / Seloger scraping with Scrapy (Python)
• Discussions about Blockchain
  • General discussions to raise the knowledge of everyone
  • Main net / Test net / Token Economy
  • Comparisons
  • Features planning
  • Blockchain-based project architectures
  • DPOS strategy for Berty
  • La suite du monde strategy
  • Osmose strategy
  • Busy strategy
  • Blockchains comparisons
• Architecture of an event ticketing & wallet system based on the blockchain
• Fun
  • Blobby Volley, Jackbox
  • Nom nom nom
  • IRL Cryptography/Steganography game (fake telepathy)

Volatile Blockchain / Temporary Blockchain

The idea

Merge the concepts of

• “Connected Blockchains” (see https://cosmos.network for a good example)
• Autonomous networks that support split & merge

To obtain a way of creating a temporary blockchain in an autonomous network that can exists over mesh network (bluetooth, isolated networks, isolated countries, etc).

Challenges

• Determine the best consensus rules that allows a smaller network to “take decisions”
• Offer the option to automatically convert the temporary coin to a permanent coin as soon as networks are merged

Examples

• Create a temporary blockchain for a music festival, allow people to convert their existing permanent coins to the temporary money, lose internet during the event, and then translate-back the unused temporary coins
