BTCIOT - bitcoin mesh diary, part 1

Here's a summary of the WCN episode "BTCIOT - bitcoin mesh diary, part 1" from 2019-04-29:

Summary:

This episode introduces the "Bitcoin Mesh" (BTCIOT) project, aiming to create a low-cost mesh network for transmitting Bitcoin transaction data. The project leverages inexpensive ESP32 microcontrollers (ranging from $1.50 - $6 each) to build a self-healing and antifragile network, initially envisioned for deployment in Mumbles, Wales. The speaker demonstrated the setup process, utilizing Expressive Systems' Mesh Development Framework (MDF) for greater stability compared to previous Arduino-based approaches. The network utilizes a TCP server (Packet Sender) for data transmission and incorporates redundancy with automatic node nomination. The team successfully tested basic communication by controlling LEDs on different devices, demonstrating both unicast (targeted) and broadcast (all devices) functionality. The project encourages community involvement and experimentation with the ESP32 devices to expand the network's range and ultimately broadcast Bitcoin transaction data to local villages.

Main Topics:

• Introduction to the Bitcoin Mesh project and its goals.
• Use of ESP32 microcontrollers for a low-cost mesh network.
• Demonstration of the Mesh Development Framework (MDF).
• Configuration of network parameters (Wi-Fi credentials, IDs, passwords).
• Testing basic communication and LED control.

Key Quotes:

• "We're looking at a system with contact points like Bitcoin full nodes and blockchain satellites."
• "It’s about creating something that’s antifragile, that gets better with stress."
• "We're encouraging people to contribute and experiment with these inexpensive devices."

People Mentioned:

• The host (unnamed)
• Expressive Systems (regarding MDF)
