Pre-Event Preparation

Logistics

• Make sure you have the appropriate adapters and cables needed to screen share

• Make sure you know how to keep your computer’s display on (for Ubuntu, it’s Settings > Power)

• If there will be time for people to play on their own, have a playlist ready and a slideshow

• Make a doc of event logistics

  • Time to meet

  • Volunteer expectations and responsibilities

  • Things to bring (adapters, stickers/swag)

Things you will need to explain

Here's a list of things the facilitator should be prepared to walk through

Chapter 1

• Explain what a block explorer is. Mempool.space is a popular one. With all of the recent drama with OP_RETURN can mention that chapter 1 only covers two of the ways you can put arbitrary data into the blockchain.

• Different ways to encode data, what the xxd command does (see the help page for that exercise)

• Explain what ASM means when we see it in a block explorer (ASM in the scriptSig field stands for "Assembly" and it represents a human-readable format of the script instructions within a transaction.)

Chapter 2

• Write a while loop that creates a hash (JavaScript or Python). Satsie's answer (you can also get an answer from the help button)

function findHashFromNonce(nonce) {
  // Try computing the hash with the given nonce
  let hash = crypto.createHash('sha256').update(nonce.toString()).digest('hex')

  while (hash.substring(0, 5) !== "00000") {
    ++nonce
    hash = crypto.createHash('sha256').update(nonce.toString()).digest('hex')
  }

  // console.log(hash)
  return nonce
}
