With Africa's rise in share of global Bitcoin mining hashrate now just under 4%, the question is how this hash power is being used and by whom 📌

In my latest for Forbes Crypto, I look into Africa's "Hashrate Exfiltration Problem" and future outlook.

"Put simply, “hashrate exfiltration” is the use of a region's hashrate by a foreign entity or power in furtherance of its interests, often at the region's expense. [...] The legacy of resource extraction in Africa may see another unfortunate renaissance in Bitcoin mining if care is not taken."

"Africa’s resilience against all these odds will set the global template for building resilient money and energy infrastructure, ensuring a future of hope and abundance for all."

Here is my talk, "A Bitcoinized Africa," from last week's @npub1yul83... Baltic Honeybadger '24 conference #BH2024

This year, I decided to give a more concise presentation, based on a lot of feedback and requests, on why Africa will continue to play a significant role in Bitcoin's overall development and future success.

Share this presentation with anyone curious about "what material benefits Bitcoin brings to humanity" or "what Africa's role is in the future of Bitcoin."

"Africa will not only continue to show what Bitcoin can do but, more importantly, it is going to show what we can do with Bitcoin" 🔥

Regarding the recent Proton Wallet, I respect their conscious effort to be transparent and open about the tradeoffs / threat model (especially in their recent blog posts; see below).

I just tested out the wallet, great work.

Though not perfect ATM, they seem to be on a good path so far in building a Bitcoin-only wallet to simplify sending and receiving Bitcoin for their 100 million Proton users.

Presently, they appear to use the Bitcoin Dev Kit (BDK; see below) as a dependency, with coinjoin and the Lightning Dev Kit (LDK) on their radar. Hopefully, we will see silent payments integrated down the line, too.

Nevertheless, as a Proton user, I look forward to seeing how the Proton Wallet evolves 🔥

With all the ETF news taking up bandwidth, I thought it would be worthwhile to document what I think is a very important project, announced at last week's Adopting Bitcoin Cape Town conf.

The Bitcoin Java Card project by KG, developer of Machankura, could be the missing piece to bringing Bitcoin to billions in Africa, and globally.

Cash is universally a vital source of economic power; hence, an attack on cash is an attack on a crucial freedom—financial freedom.

Given the current situation in Nigeria, it's important to remember that cash is not only essential for privacy, but it remains a critical financial bridge and a lifeline for the unbanked.

In a cashless environment, Bitcoin becomes their only alternative.

Though there is still hope, we must remain focused and vigilant to eliminate complacency.

Financial freedom is not a shiny feature on an app. For Bitcoin, it is a consequence of having a protocol with a free open, accessible, permissionless, decentralized Global monetary network that allows people to take back control of their money. A more pertinent realization is that moving forward, this will require even more work to protect and preserve.

Attacks on freedoms will never end, so we must, inter ala, continue to build and fortify ourselves to the very end.
