🌟 Adam Back: The cryptographer who inspired Satoshi

Today’s spotlight is on a figure who shaped Bitcoin from the shadows. His ideas helped define the first cryptocurrency — and still influence its future.

(Previous post on Satoshi Nakamoto)

Adam Back is a British cryptographer, inventor of Hashcash, and CEO of Blockstream — a company focused on building Bitcoin infrastructure.

🔖 Back introduced key concepts that Bitcoin was built upon:

➡️Proof-of-work as resistance to spam and trust-based systems

➡️ Decentralization and censorship resistance

➡️ Scaling through sidechains and the Lightning Network

Why he’s a foundational figure in crypto:

➡️Creator of Hashcash — directly cited by Satoshi in the Bitcoin whitepaper

➡️ One of the first people Satoshi contacted while developing BTC

➡️ Co-founder of Blockstream — a major player in Bitcoin’s second-layer tech

👀Fun fact: Adam Back is often named as one of the few "living candidates" for being Satoshi. He denies it — but his technical background and timing make him a frequent suspect.

➡️Back is the bridge between 90s crypto-anarchism and today’s blockchain infrastructure. His work is where theory meets real digital freedom.
