If you understand how to participate in the Edgeware Lockdrop, but want to nominate yourself as a validator at the launch of the Edgeware network, there is a short list of things you need to do first before completing the Lockdrop process. While this process doesn't guarantee that you will be a validator, it does enable your selection. At launch, Validators will be selected from the largest lock amounts from the set of nominated Edgeware Public Addresses.

Walkthrough: How to Participate in the Edgeware Lockdrop

A guide to becoming a Validator through the Lockdrop


First, validators on Edgeware (and Polkadot) have 3 keypairs: a hot wallet, a warm wallet, and a cold wallet. (You can learn on this 3-keypair setup here.)  To begin, we will generate:

  • TWO sr25519 Edgeware Keypairs
  • ONE ed25519 Edgeware Keypair

There are two ways to generate these keypairs. We encourage you to read both methods and choose the one you prefer. First, let's perform the pre-requisites to both methods:

Prerequisites

  1. Install the Rust programming language - See a guide
  2. Download the Subkey program using the following command within your command line interface (CLI):
 ✗ cargo install --force --git https://github.com/paritytech/substrate subkey

Now we are ready to generate our keypairs.


Method 1: Create Separate Mnemonics for Each Keypair

Note: You will need to store 3 different mnemonics to have access and control over the funds and functions of these accounts.

This method uses the subkey generate command in three instances and returns your mnemonic phrases, your seed, your hex-encoded public key, and your public address. To reiterate, with each instance of this command, you want to securely record the results, otherwise you may lose control or access to these wallets. Notice that, because we need one keypair with a different parameter (the ed25519 keypair,) the last command is subkey -e generate

Once complete, you should have 3 phrases, 3 seeds, 3 public keys, and 3 addresses. The commands and the output will look like this (minus the # titles):

# SR25519 MNEMONIC KEYPAIR 1

✗ subkey generate
 Phrase `meadow clip planet heavy afford rifle viable bus fury satoshi blue impose` is account:
  Seed: 0x225967f0f82c4958179f9ba1c9b8823b0bc87fca650d7f3181bd2131f54276ec

# ED25519 MNEMONIC KEYPAIR 3

  Address (SS58): 5Cab1dV9g8hb2MrBcVUjCyFEJBqBWZZ4djHRE4pBYHbk4kyB

Method 2: Create 1 mnemonic and derive keys

Note: You will only need to store the top level mnemonic for this approach.

As you will see below, we reuse just one mnemonic to generate more keys by appending a string to the mnemonic phrase. For instruction purposes, we recommend you append stash , controller and authority (the names of the wallet's purposes) but you can append any string.

Step 1: run subkey generate and record the results.

Step 2: run subkey inspect "YOUR MNEMONIC FROM STEP 1 IN QUOTEMARKS" //stash  and record the results. This is the info for the stash wallet.

Step 2: run subkey inspect "YOUR MNEMONIC FROM STEP 1 IN QUOTEMARKS" //controller  and record the results.This is the info for the controller wallet.

Step 2: run subkey -e inspect "YOUR MNEMONIC FROM STEP 1 IN QUOTEMARKS" //authority  and record the results. This is the info for the authority wallet - make sure to notice and include the -e parameter in this step.

Ensure you create and submit 2 sr25519 and 1 ed25519 public keys when participating in the Edgeware Lockdrop. Your commands and output will look like this:

3.   Concatenate the three stash, controller and authority public keys together, removing the 0x in front of the controller and authority keys (or 2nd and 3rd keys if you used different strings) before concatenating them, leaving only one instance of 0x at the beginning of the final string.

This final string should be 194 characters regardless of your choice of method.

Example of Method 1 Concatenation (3 separate mnemonics):

0xc2e973c4d848d25613141ef883bf97d35b513230427f52c56d2bf92bc4fa365cfeba4989f1de5fe7aa911f9abed67742b93099701d4f9b0e07b8ac35e2f7813116ca51710516a648e016b00b8872cb37946dc1aabd531021d593e1d76604cf40

Example of Method 2 Concatenation (1 mnemonic):

0x807d3de39cf5cb33c54bf2f839711f9f776c0b3f140228a2edf1336f7ff65602403ac86021d47fc9df6e0a8fd27396393dc7dfd40722a09a7b31d99730eaf96226b7b23056e3fe175354a7401777e358a231a3d4d7544431f824aa49b2171522

Edgeware Lockdrop

When you are ready to participate in the lockdrop, you will submit that concatenation of your three public keys as your input into either the:

  • The field labeled "EDG public key (hex)" in the Lockdrop UI
    -or-
  • If you are using the CLI, as your --edgewarePublicKey

Once you finalize your participation in the lockdrop, you are done - you have successfully submitted your intent and nomination to validate on the Edgeware network.

Why? More on stash, controller and authority

In order for us to generate the genesis specification for the Edgeware chains, validators are identified by 3 keys: a stash (sr25519), controller (sr25519), and authority (ed25519) key.

  1. Stash accounts control the stake and bond to controllers.
  2. Controller accounts control staking settings
  3. Authority accounts author blocks and more.

Therefore, when you participate in the lockdrop, we will need to have access to three keys per validating locker. With this, we can simply parse out the keys and setup the chain spec as intended.
