I’ve started teaching a series of bitcoin workshops.

The goal of this project is to help people learn about bitcoin, that’s all.

I plan to open source this workshop, as in I’ll share pretty much every resource I use and the steps I take to teach it.

It’s not very hard and I’ve been lucky to have students who understood everything in every lesson so far.

The workshop is aimed at beginners.

Here’s some resources I’ve used. These are a shout out as well to say thank you.

I’ll post more articles about this on my blog. I’m sharing a page with most of the resources and links with the students, which is https://georgesaoulidis.com/workshop

Bitcoin Games Explained

Bitcoin games for better teaching and comprehension. I suggest we do these after the theory and before the practical workshop stuff.

Blockchain game.

  • Needs only pen and paper from participants. A board for the teacher and a 3D printed bitcoin to pass around. Some random items to trade for the bitcoin.
  • We play blockchain transactions on paper. Participants act as nodes.
  • Explain concepts and definitions on the way. Genesis block, block height, immutable ledger, append-only database, miner fees.
  • Give the coin to the first person, who is Satoshi. He sends the coin to someone else, everyone writes it down on blockheight 1. Everyone compares notes, approves the transaction.
  • Second transaction, third, etc. Explain stuff along the way.
  • Then have one participant go offline, catch up later by asking his connected peers for the updated blockchain. One participant has a catastrophic node failure, downloads the complete blockchain from his peers.
  • Important, have one participant try to double-spend his coin. Other nodes check their ledgers, reject the transaction.
  • Answer questions, wrap up the game.

Lightning game

  • Needs pieces of string and some hex nuts or metal washers, maybe. See what works better.
  • Explain lightning layer 2, pass around some sats to participants, e.g. 20 sats each.
  • Have them open a channel, hold the piece of string between them. Fund it with sats. Spend 1 sat for the on-chain transaction of channel open.
  • Push a payment through, push the sats along the string.
  • Open a second channel, transact.
  • Forward a payment, show how sats do not leave their channels.
  • Ask for a payment that does not have inbound liquidity. Explain how to fix this, incoming channel liquidity or circular rebalancing. Explain rings of fire, the best arrangements for increased connectivity. Explain channel girth.
  • Try some real world scenarios, one node is the baker, another is the cafeteria. Explain how channels open for recurring payments. Explain how merchants like not paying card fees and how the transactions are not reversible.
  • Explain channel closes and how to get your sats back on chain. Explain how it will become the internet of money.
  • Answer questions, wrap up the game.

1st Lesson Notes

Links at georgesaoulidis.com/workshop

Lots of metaphors. Be patient and don’t take things literally. Satoshi himself said that this is so hard to explain because there’s nothing to compare it to. Thankfully in the decade past there have been hundreds of educators and thinkers in the space and we’ve come up with simple, proven explanations for bitcoin concepts that work just fine for the layperson.

How old is bitcoin? Bitcoin has been in the making for over 50 years now.

Wallet/signing device

Where is bitcoin stored? Not in the wallet.

Not your keys, not your coins. Andreas Antonopoulos NYKNYC. Drill the importance of this in, repeat it, explain it five different ways, make them say it themselves.

Download Bluewallet, a wonderful multitool. Get them all to do it themselves and learn the process. Create wallet, write down seed words. Delete wallet, restore.

Watch only address. Other people can watch too.
Avoid address reuse.

Explain wallet concepts and have them repeat it. The goal is for them to understand what they’re doing each time they use a wallet.

  • Custodial / Non-custodial
  • KYC / Non-KYC
  • Hot Wallet / Cold Wallet
  • Software Wallet / Hardware Wallet
  • Hosted/Unhosted wallet (Inverse terminology)

Hardware wallet.
Data hack dangers, Ledger. Giveaways only if they’re sent directly from the company. Never use Second-hand wallet. Buy only direct from the company.

NFT store them where?

Wallet discussion:
-Bluewallet (BTC/lightning, phone)
-Phoenix (lightning, phone)
-Coinomi (BTC, phone)
-Sparrow (BTC, desktop)
-Trezor (BTC, hardware)
-bitbox02 (BTC, hardware)
-Ledger (BTC, hardware)
-Breez (lightning, software) POS.
-Wallet of Satoshi (lightning, software)
-Metamask How to avoid scams. Does it hold BTC?

Did You Like What I Made? Then buy me a frappe. You can support me on Patreon, Starbackr or BuyMeACoffee. My preferred method is bitcoin sats over lightning. There is no exclusive content there but that way you can make sure these stories and renders keep on coming.
