Title: Spam attack on bitcoin blockchain increases blocksize to 3MB
Post by: 0zero0 on July 17, 2019, 02:15:15 PM
I just found this article on Cointlegraph which said that on July 14 a spam attack was carried on the bitcoin blockchain.
This spam attack turned the bitcoin blocksize from 1MB to 3MB through invalid transactions.
I knew that spam attacks have previously been performed on the bitcoin blockchain but I never knew it could increase/decrease the blocksize.
Anyway, since the transactions were invalid and probably got kicked out of the blockchain, it didn't create any impact on the price.

i can not find any block that was 3 MB on bitcoin blockchain so far not just recently! the biggest record is 2.377 MB!

and on those two dates mentioned in the article the biggest block size was 1.9 MB so i don't know where they are getting 3 MB from!

as for VeriBlock, they have been spamming bitcoin network for some time now. and it is not just them, there are many other altcoins that are spamming bitcoin like a parasite living off of it.

The article is click-bait.

This spam attack turned the bitcoin blocksize from 1MB to 3MB through invalid transactions.

That is impossible.

I knew that spam attacks have previously been performed on the bitcoin blockchain but I never knew it could increase/decrease the blocksize.

The size of a block depends on the transactions it contains. If there are many "spam" transactions, then it will be bigger. BTW, what is a "spam" transaction?

Anyway, since the transactions were invalid and probably got kicked out of the blockchain, it didn't create any impact on the price.

There is no such thing as kicking invalid transactions out of the block chain, and the size of the blocks have no impact on the price.
