On April 12, 2009, with the price of BTC still at $0, Satoshi Nakamoto began exchanging emails with Mike Hearn, a Google developer who would later become a key figure in the Bitcoin ecosystem. This moment marks one of the first key interactions in the history of Bitcoin.

🧠 Topics they discussed:

• Mining: How blocks were validated, incentives for miners, and the evolution of hash rate.

• Transaction speed and size: Technical limitations, potential bottlenecks, and how to scale the network.

• Security: Prevention of attacks, double spending, and robustness of the protocol.

• Long-term vision: Satoshi shared ideas on how Bitcoin could evolve, including aspects like privacy and governance.

📬 Importance of the exchange: This dialogue not only helped refine technical aspects of the protocol but also laid the groundwork for a community of developers who would eventually take over after Satoshi's disappearance. Mike Hearn was one of the first to try to bring Bitcoin to wider adoption, although years later he would distance himself from the project due to philosophical differences about its direction.
