Ignoring social attacks, there was Portland Hodl’s IBD request attack against Comcast knots nodes
Discussion
Who is Portland Hodl? (I don’t see him listed as a contributor to any recent Bitcoin Core release…)
He’s an active core contributor. He’s on the mailing list. Mainly working DoS issues AFAIK
I see.
Well exactly because Bitcoin Core is a free and open source project, anyone can contribute to it. I don't think you should hold the entire project accountable for the actions of any one individual.
Nor does it change the nature of the free and open source model; anyone can still fork the code.
Of course any project that operates on the open internet can be attacked in all kinds of ways, including Bitcoin Core itself. Being a FOSS project doesn't prevent that.
(To be clear I have no opinion on whatever it is Portland Hold may or may not have done because I know nothing about this.)
