Shelley Stakepool Pioneers Exercise Sheet 3

#!/bin/bash

# FnF Exercise 3
# 1. KES Mechanism (for rotating operational cert)
# - Generate the cold (offline) key pair that is used to evolve the operational certs (using new hot KES keys periodicaly).
# - Generate the hot KES (offline/online) key pair for generating the cert.
# - Generate the operational cert (offline) based on the evolved KES and VRF key.

Excercise 2

1. Build simple transactions using the basic transaction mechanism;
2. Sign transactions and confirm that the transaction is complete;
3. Submit transactions to the Pioneer Blockchain;
4. Verify that the transactions have been processed by inspecting the addresses that they have been sent to.

Layman explanation of COVID-19

Pathophysiology

1. Viruses need enter the host for reproduction i.e.:
   • a. host's cells for reproduction,
   • b. host's body for finding new cells to invade.
2. SARS-CoV-2 enters through the (mucosa) of the
   • a. respiratory (lower, higher) tract (higher probability) e.g.
     • higher: epithelial cells of oral mucosa (lower probability)

• lower: type II pneumocytes of alveoli (highest probability)

# P2P Section explanation
p2p:
  # This is the node's `identifier` in the Poldercast topology. This should be unique and 
  # deterministic (which is not the case in jormungandr) in the poldercast network, and
  # it's highly recommended to be set, because a random `id` is generated on every node restart otherwise.
  # So, we introduced a free sybil attack against to the Poldercast's nodes in default (if it's not set).
  # It simply means that the number of nodes (node ids /w address) in the poldercast increasing by every node's restart
  # and just forgotten very slowly. Therefore, currently there are ~80K node entries in the topology, 
  # which can be one of the reasons the nodes block/slow sometimes.

The Hitchhikers Guide To The Shelley - Chapter 2 - The Lock, Stock And Two Smoking Barrel

This chapters covers the information how the nodes are communicating to each other in the underlying P2P network.

The Lock - The kyklos the Tornado's gossips

In jormungandr each node maintains a list of all available (reachable/unreachable) nodes (neighbours) of the overlay, from which it selects:

• a random recipient to gossip and
• a fixed-size (default=10) number of nodes from the overlay for gossip.

This chapters covers the information about the underlying P2P network of Shelley's ITN implemented in Jormungandr.

The Explanation

The very simple explanation of the poldercast network relating to jormungandr.

• Poldercast is a Topic Based Pub/Sub System.
