I have recently received a job offer to work on a blockchain implementation. While the offer was very generous, I had to turn it down. In this post I want to collect the thoughts that went into my decision process leading to this conclusion.

Learn to write and modify Zero Knowledge Proofs from scratch. You'll build a digital signature scheme using hash-based commitments, gaining practical ZKP programming skills and intuition along the way. By the end, you'll have all the tools you need to implement things like group signatures.
Taylor Swift, like Dave Chappelle, is leveraging the power of the Internet to take control of their art.
To solve Bitcoin’s scalability challenge, many so-called layer 2 protocols have been proposed. All of these protocols operate on the same, relatively simple, principle:
With over $20b in assets under management Celsius Network is the biggest centralised lending platform in the crypto space.
I won’t discuss anything in this post. I’m tired of discussing technical things with people with skewed opinions and monetary interest. I’ve talked enough in the Bitcointalk forum…
On March 13, the Dencun hard fork activated, enabling one of the long-awaited features of Ethereum: proto-danksharding (aka EIP-4844 , aka blobs). Initially, the fork reduced the transaction fees of rollups by a factor of over 100, as blobs were nearly free. In the last day, we finally saw blobs spike up in volume and…
The term “web3” seems pretty fluid and is being used as a label for a bunch of disparate ideas. Given that it’s a decentralized group describing a decentralized movement, that lack of focus isn’t exactly surprising.

(Sequel here: Blockchain is not only crappy technology but a bad vision for the future.)
Bluenoroff or APT38, more commonly referred to as Lazarus Group is a threat group which has been tied to the North Korean government since as early as 2009 primarily being financially motivated utilizing malware custom built for each target.
On 2/2/2022, I reported a critical security issue to Optimism—an "L2 scaling solution" for Ethereum—that would allow an attacker to replicate money on any chain using their "OVM 2.0" fork of go-ethereum (which they call l2geth).
Last weekend I attended the Satoshi Roundtable conference along with Charlie Lee and about 70 other members of the bitcoin community.
Last week a group of technologists, including Bruce Schneier, sent a letter to Congress outlining their concerns around cryptocurrency and urging Congress to regulate the space. Now let me be the f…
Financial theory demonstrates that the concept is fundamentally flawed
I just bought put options on MicroStrategy ($MSTR) , Coinbase ($COIN) , and Purpose Bitcoin ETF ($BTCC-B.TO) , all at a strike price not far off the current (late June) price, expiring around Christmas. Here’s the thinking.

Shorter title: SBF, FTX, WTF?
You have just made a Bitcoin transaction and you are eager to see if it appears in the next block. You know that the expected time between Bitcoin blocks is 10 minutes. You check the log of your Bitcoin node. It has been 7 minutes since the previous block. You recall that blocks occurrences in Bitcoin are a Poisson…
The hedge fund's finances appear to rest on the same scheme that destroyed Celsius Network. Will it work out any differently for Sam Bankman-Fried?
I recently became interested in identifying the pseudonymous creator of Bitcoin, Satoshi Nakamoto. I started from the Bitcoin whitepaper [0] published in late 2008, and proceeded to run reverse tex…
Digital, but still a barbarous relic.
