When Satoshi Nakamoto mined his first set of blocks in 2008/2009, it was on Bitcoin core, but was he using Linux or Windows?

The question seems anectodic but it has an importance when reading the old key.MakeNewKey() source code :

  1. At that time, coinbase transactions of 50Btc were sent to a newly generated pubkey at each blocks. As far I can tell, each key were added to the wallet at the approximately the block’s timestamp.
  2. Bitcoin core was using /dev/urandom on Linux but on Windows even when openssl was asked for secure randomness, the generator had to be initialized manually each time to a initial value : and in the case of key generation, that value was set to HKEY_PERFORMANCE_DATA by Satoshi !

So if I’m not wrong, this means coinbases mined through using Windows had weak randomness as the possible values are far more limited than the secp256k1’s order. As a result, does this means he only used Linux personally ?

Crypto Exec Warns Tokenization Is Moving Faster Than Expected

Image
According to a post shared on X by Keith Grossman, president of crypto payments firm MoonPay, finance is heading toward an onchain future that could unfold over several years. The view comes as large banks and asset managers begin product tokenization, a move that once seemed extreme but is now being treated as a practical step by major institutions. Regulatory Signals Push Institutions Forward Based on reports cited by Grossman, progress has accelerated because rules are becoming clearer. Legislative efforts, regulatory guidance, bank involvement and accounting standards are starting to line up. That combination reduces uncertainty, which is often what slows large pools of capital. BlackRock has already launched tokenized funds, while Franklin Templeton is running tokenized money market funds on public blockchains. Those actions suggest that tokenization is no longer confined to pilot labs or internal trials. It is being used with real assets and real clients. Bank of Ameri...

Bitcoin Mining Could Be Strengthening The Ruble, Russian Central Bank Says

Image
Bitcoin mining may be providing incremental support to the Russian ruble, Central Bank Governor Elvira Nabiullina said, while cautioning that the effect is difficult to measure because much of the sector still operates in a legal and reporting gray zone. Bitcoin Mining May Support The Ruble Responding to a question at a press conference, Nabiullina said it is “probably difficult to quantify” mining’s influence “because a significant part of mining is still in a gray area.” Still, she added that mining is “indeed one of the additional factors contributing to the strong ruble exchange rate.” As Russian business news portal for RBC reported , her remarks come as Russian officials increasingly frame mining and crypto flows as macro-relevant, not just a niche tech or energy story. Earlier, Maxim Oreshkin, deputy head of the presidential administration, said ruble forecasts have been thrown off by the underestimation of financial flows tied to mining and cryptocurrency. In his view, the s...
