Keybase proof

I hereby claim:

• I am ilap on github.
• I am ilap (https://keybase.io/ilap) on keybase.
• I have a public key ASDiVDzi9NTlM-daMMe8wYkGarcITtk01vpk1KQ6wKWw2go

To claim this, I am signing this object:

#!/bin/bash

# Get the spending key of your Yoroi address for signing the spending.
# At repl.it/repls/IndolentWarmheartedDehardwarization
# FORK IT FIRST!!!!!!!!!!!
# And replace the 
# MNEMONICS="your mnemonics" with yours and then
#     from `console.log(address.to_base58());``
#     to `console.log(key_prv.to_hex());`

# 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.

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)

# 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.

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

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)
