i have always heard that there were no limit for block size. so i am very interested to know where you brought your 32 MB from. can you provide a reference for what you said?

but i know that Satoshi set the limit of 1 MB because there were fear of spam attack that can fill the blocks up fast and with useless transactions and waste space. so the limit is there to prevent flood!

p.s. why did you post this question in Economics board?!

You can look at the Bitcoin Wiki to get some background.
https://en.bitcoin.it/wiki/Scalability_FAQ


Bitcoin Core was initially released without an explicit block size limit. However, the code did limit network messages to a maximum of 32 MiB, setting an effective upper bound on block size.[2]
Around 15 July 2010, Satoshi Nakamoto changed Bitcoin Core’s mining code so that it wouldn’t create any blocks larger than 990,000 bytes.[3]
Two months later on 7 September 2010, Nakamoto changed Bitcoin Core’s consensus rules to reject blocks larger than 1,000,000 bytes (1 megabyte) if their block height was higher than 79,400.[4] (Block 79,400 was later produced on 12 September 2010.[5])

... Statements by Nakamoto in the summer of 2010 indicate he believed Bitcoin could scale to block sizes far larger than 1 megabyte. For example, on 5 August 2010, he wrote that "[W]hatever size micropayments you need will eventually be practical. I think in 5 or 10 years, the bandwidth and storage will seem trivial" and "[microtransactions on the blockchain] can become more practical ... if I implement client-only mode and the number of network nodes consolidates into a smaller number of professional server farms" [7].

These statements suggest that the intended purpose of the 1 megabyte limit was not to keep bandwidth and storage requirements for running a Bitcoin node low enough to be practical for personal computers and consumer-grade internet connections, and that the limit was intended to be lifted to accommodate greater demand for transactional capacity.
