Documentary about Bitcoin in South Africa with Anita Posch on German TV
German TV stations ARD and BR published a Bitcoin documentary for which they followed Anita Posch to South Africa where she 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 the documentary is very well done. Some things are 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. Anita dedicated a whole chapter of her book to the question of Bitcoin’s ecological footprint.
Other outcomes of this journey are:
- BFF 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 with the Ekasi team; the hardware wallets are now securing the shop owners bitcoin.
