> "36 TB per year" Satoshi made a similar argument in Nov 2008 in response to a claim about Bitcoin not being able to scale: "The bandwidth might not be as prohibitive as you think. A typical transaction would be about 400 bytes (ECC is nicely compact). Each transaction has to be broadcast twice, so lets say 1KB per transaction. Visa processed 37 billion transactions in FY2008, or an average of 100 million transactions per day. That many transactions would take 100GB of bandwidth, or the size of 12 DVD or 2 HD quality movies, or about $18 worth of bandwidth at current prices." "If the network were to get that big, it would take several years, and by then, sending 2 HD movies over the Internet would probably not seem like a big deal." https://www.reddit.com/r/btc/comments/6navjt/very_first_discussion_of_bitcoin_by_satoshi_btc/ https://www.reddit.com/r/btc/comments/6navjt/very_first_disc... Note: this was before the DoS attack in 2009 where hackers tried to freeze the network by creating blocks of uneven or massive size. Which is why in Oct 2009, satoshi imposed the 1MB block size limit (I presume was intended as a temporary stopgap measure) to prevent future similar attacks.

Long after the 1 MB limit was put in place, Satoshi wrote: >>The current system where every user is a network node is not the intended configuration for large scale. That would be like every Usenet user runs their own NNTP server. The design supports letting users just be users. -July, 2010 >>It would be nice to keep the [block chain] files small as long as we can. >>The eventual solution will be to not care how big it gets. >>But for now, while it’s still small, it’s nice to keep it small so new users can get going faster. When I eventually implement client-only mode, that won’t matter much anymore. (note to readers, "client-only mode" refers to SPV mode) -August, 2010 and in an email to Mike Hearn: >>The existing Visa credit card network processes about 15 million Internet purchases per day worldwide. Bitcoin can already scale much larger than that with existing hardware for a fraction of the cost. It never really hits a scale ceiling. So your explanation for his reasons for putting in place the 1 MB limit are not consistent. Others have said that he was afraid that someone would soon come out with GPU miners and be able to DOS the network with large blocks, so put the limit there as a temporary measure. Now that mining hardware evolution has slowed, and the mining ecosystem matured, this kind of threat is non-existent.

  > "So your explanation for his reasons for putting in place the 1 MB limit are not consistent" Actually the reason I stated is consistent with what satoshi said: "In 2010, a block size limit of 1 MB was introduced into Bitcoin by Satoshi Nakamoto. He added it hidden in two commits[1] in secret, when challenged publicly he said it is a safety measure to prevent miners from creating large spam blocks."

    But not consistent with what he said after the limit was put in place (see the quotes I provided). The motivation I suggested is consistent with all of his actions and statements.
