Why Did Satoshi Decide to Use Secp256k1 Instead of Secp256r1?
Secp256k1 and secp256r1 are two commonly used curves. Hyperledger / Fabric developed by IBM is using secp256r1 while Bitcoin is using secp256k1. What is the difference between these two and why did Satoshi decide to use secp256k1 which is considered as a surprising choice at the time?

I Am Not Satoshi Nakamoto
This isn’t the first time I’ve received an e-mail like this: Hey! I’ve done my research and looked at a lot of facts and old forgotten archives. I know that you are Satoshi, I do not want to tell anyone about this. I just wanted to say that you created weapons of mass destruction where niches remained poor and the…

Ethereum is a Dark Forest
It’s no secret that the Ethereum blockchain is a highly adversarial environment. If a smart contract can be exploited for profit, it eventually will be. But this unforgiving environment pales in comparison to the mempool. If the chain itself is a battleground, the mempool is something worse: a dark forest.

I Am Parting with My Crypto Library
The time has come for me to find a new home for my (paper) cryptography library. It’s about 150 linear feet of books, conference proceedings, journals, and monographs—mostly from the 1980s, 1990s, and 2000s. My preference is that it goes to an educational institution, but will consider a corporate or personal home if…
