Discard earlier part of blockchain to save space?

It seems like discussions about increasing the block size are related to concerns about the blockchain getting too big, so that individuals can no longer run their own node. My question is why can't the community just agree to discard, for example, all blocks earlier than 800,000 and just move forward with a smaller blockchain? I know that each new node is supposed to verify all transactions going back to the genesis block, but that has already been done thousands of times, and we all agree that all those transactions are valid. It seems like starting with block 800,000 and the known set of UTXO's at that point, is just as secure as going back to genesis, and it would allow the scalability discussions to include the possibility of larger block sizes as a solution, without disadvantaging smaller users by creating a hugh blockchain. What am I missing?

Crypto Exec Warns Tokenization Is Moving Faster Than Expected

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...
