Summary of Kusama Validator Lounge, Kusama Watercooler chats up to 11th September 2019

• prometheus exporter - https://github.com/w3f/substrate-telemetry-exporter

  • it expects to run in the same host as a telemetry backend
  • you can run your polkadot nodes in different hosts and configure them to send telemetry data to specific remote telemetry backends as usual, so that you can send data to a backend with the exporter connecte
  • do the same as in the Dockerfile, from a clone of that repo you can run yarn && yarn start

• polkadot secure validator - https://github.com/w3f/polkadot-secure-validator

  • @anson:web3.foundation, @federico:web3.foundation
  • terraform takes care of it on the complete secure validator setup, that's why i wasn't understanding

• Colony
  • About
    • Colony Network is an open source Ethereum-based protocol providing a general purpose framework to create, operate, and monetize digital companies (internet-native version of traditional organisations) by providing essential functions including: ownership, structure, authority, and human and financial management.
    • Colony infrastructure uses an upgrade pattern that is backward compatible
    • Tools to organise and incentivise a team, community or contributors. Coordinate work, manage budgets, and make decisions from users (collectively from members) according to their ability and reputation-weighted token holdings.
    • Codified structures of reputation, domains, permissions, and incentives, to coordinate working relationships within the permissionless digital companies that use smart contracts and blockchains.
  • Use Cases
    • DAOs
      • Startup wanting to meritocratically split ownership between founders
      • Musician wanting to harness passion of your fanbase

Accounts

Different accounts are used to manage funds. The underlying cryptography of their account keys is the same:

Stash

• Primary account
• Holds funds. Usually a cold wallet (on piece of paper in a safe, or protected by layers of hardware security)
• Bonds (locks) a portion of its funds with a Controller for participation (since the stake key is kept offline)
• Unbonding requires waiting ~600 blocks before unlocked funds accessible again
