Hello professionals,

I am amatour but I know that Satoshi created Bitcoin with Blockchain size like 32 MB.

1. Who and why changed it to 1 MB ?
2. Why can`t we back to 32 MB ?

Hello professionals,

I am amatour but I know that Satoshi created Bitcoin with Blockchain size like 32 MB.

1. Who and why changed it to 1 MB ?
2. Why can`t we back to 32 MB ?

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.

WOW I did not know about this size thing. I am interested in it a lot now. The size is really important for transaction I guess as it it gives indirect confirmations from block solving. So is it like bigger the block size more is the time it takes? From your statement I am thinking it is related to bandwidth stuff more rather than transactions. Its great to know that bitcoin creator thinking about personal computer easiness as well as consumer grade internet connections.  Cheesy

Hello professionals,

1. Who and why changed it to 1 MB ?
2. Why can`t we back to 32 MB ?

Someone predicted it in the past Satoshi said the community will establish consensus and increase the size.
Did not predict the drama
----------------------------------------
Quote from satoshi:
It can be phased in, like:

if (blocknumber > 115000)
    maxblocksize = largerlimit

It can start being in versions way ahead, so by the time it reaches that block number and goes into effect, the older versions that don't have it are already obsolete.  When we're near the cutoff block number, I can put an alert to old versions to make sure they know they have to upgrade.

Satoshi programmed bitcoin to be mined at 1 mb during its launch and it will increase as bitcoin is developing over the years. It means that the more users bitcoin has the blocksize will increase. But the problem is that satoshi left bitcoin behind leaving it to other developers who does not have the same views as him. Thus today the intended blocksize did not happen but instead it remained the same. Other reasons is that 1 mb blocksize is still good even today and the only problem is not on the blocksize but the spam attacks on blockchain.
