Bitcoin documentary with Anita Posch on German TV

German TV stations ARD and BR published a Bitcoin documentary for which they followed me to South Africa where I worked with Bitcoin Ekasi in May 2022. The Bitcoin township is an example that Bitcoin can be used by anyone even people in less privileged circumstances.

Overall I find the documentary very well done. There are some things factually wrong like when “Tante” is speaking about the CO2 emissions that a single transaction is emitting. It’s faulty mathematics. The use of energy for bitcoin does not scale to the number of transactions. The number of transactions that happen on-chain and the number of transactions that happen off-chain - for instance, on second-layer technologies like the Lightning Network or through custodial exchanges that batch transactions - are not correlated to the cost of mining. I dedicated a whole chapter of my book to the question of Bitcoin’s ecological footprint.

Other outcomes of this journey are: 

• I brought a raspiblitz which is connecting BitcoinEkasi with the Lightning and Bitcoin network. As they can verify their own transactions with the node, they are their own bank now.
• we set up Trezor hardware wallets which are securing the shop owners bitcoin 
  
• Peer-to-Peer Bitcoin exchange Paxful opened an education center in the township

Here you can watch the documentary in German (until 25 October 2027):
