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)

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.

# 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.

Shelley Stakepool Pioneers Exercise Sheet 4

Key Types and their functions

• Node Keys (Cold, Hot, VRF)
  • Cold key: operator's offline key pair with cert counter for new certificates.
  • Hot KES key: operator's hot KES key pair.
  • Block signing key: operational VRF key pair, it participates in the "lottery" i.e. right to create and sign the block for the specific slot.
• Address (Payment, Staking etc.) keys
• Payment key: single address key pair (usually for generating UtxO address)

Shelley Stakepool Pioneers Exercise Sheet 5

0. Run a pool to able to send transactions to the network
1. Register a stake pool
2. Delegate stake to your own stake pool
3. Start a stake pool and produce blocks
4. Receive delegation from other Pioneers

The Hitchhiker's Guide To The Shelley - Chapter 3 - The Staking

This guide's chapter targets the pool operators for getting their head around of Shelley staking. To fully understand the staking mechanism we need to define and interpret the following key concepts:

• What are the keys
• What are the addresses
• What are the certificates and
• Who are the stake holders that are participanting in staking.

The Hitchhiker's Guide To The Shelley - Chapter 4 - The Network

This guide's chapter targets the pool operators for getting their head around of current Shelley's Network stack until P2P (Governor with DeltaQ) arrives. It also provides some networking practices, for setting up a staking pool environment.

UPDATED: 14:08am AEST 29/Sept/2020, The IDX was incorrectly used. Fixed now

There are two keypairs that are required to register a pool:

1. reward account (costs and rewards) and
2. owner stake (pledge) keypair.
