I was going through the blockchain paramters, and saw that the max transaction size, max-std-tx-size is given as 100000000 bytes, which translates to ~96MB, whereas "max-std-op-return-size", is 67108864 bytes, which is 64MB. (this is the largest amout of data we can embed for a key in a stream
According to your "Production recommendations", for "max-std-tx-size", its stated - "Ensure this is large enough to accommodate the largest piece of data you will ever embed in the blockchain (but note the hard limit of 64 MB). The max-std-tx-size and maximum-block-size should both be at least a few hundred bytes larger than this value."
This makes sense, as the published stream item, say the max allowed, 64MB + other transaction data (txid, addresses, blockhash, blocktime, etc) and even if an asset tranasction is done, whose metadata is very small should be around 2-3MB at most.
So why is there such a big difference between max-std-tx-size & max-std-op-return-size? (Around 32MB?)
Is this is view of future proofing, where some other large data may be added to the transaction or am I missing something here?
