Bitcoin: Mine faster than timestamp and nonce value

So Bitcoin uses a 32 bit value nonce in the bitcoin header. This means that it takes about 4 billion hashes to run out of nonce values. There is also a timestamp in the Bitcoin header which is Unix time. This means that it only counts in seconds.

So if you get through all the nonce values for your current timestamp, you have to update the timestamp.

So if someone had a hash rate of over 4 billion hashes per second (4Gh), wouldn't you be mining too fast for there to be more things to hash?

How do miners overcome this issue? (I heard something about "rolling nonce" or "extra nonce", but I don't understand them)

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...
