Can the 520 byte push limit be circumvented for existing tapscript opcodes

Lets assume we want to introduce arbitrary precision into Bitcoin's Script language. This requires being able to push operands of arbitrary size to the stack.

BIP342 states

Stack element size limit The existing limit of maximum 520 bytes per stack element remains, both in the initial stack and in push opcodes.

It also states that new opcodes could circumvent the 520 byte push limit

Since OP_SUCCESSx precedes size check of initial stack and push opcodes, an OP_SUCCESSx-derived opcode requiring stack elements bigger than 520 bytes may uplift the limit in a softfork.

Script already has a handful of arithmetic operations such as OP_ADD and OP_SUB.

Is it accurate to say that these opcodes could only be repurposed up to 520 bytes of precision? If more precision was desired, you would need to create new versions of these opcodes (OP_ADD_ARB, OP_SUB_ARB)?

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...

Nigerian SEC Looks To Improve Crypto Investors’ Protection According to local media Voice of Nigeria , the SEC is ramping up efforts aimed at investor protection and transparent market operations in the crypto ecosystem. In a recent meeting with the NPF, the Commission’s Director-General (DG), Dr. Emomotimi Agama, communicated to the Inspector General of Police (IGP), Kayode Egbetokun, concerns over malicious actors in the financial markets who exploit investors’ trust for personal gains.  Dr. Agama said: They cloak their deceit in the glamorous but misunder...
