politics, anti-racism 

This past month or so has made it absolutely clear there is systemic , and that it is now considered socially acceptable to be racist and discriminate openly.

But it's already illegal. So the question is, when will the government prosecute? Or is this anti-"white" racism the new norm in ?

Thanks to @[email protected] for merging my BIP 8 improvements and adding me as a co-champion.
Hopefully just in time for finishing it up for deploying to !

Recording of the BitDevsLA video conference where I discuss the recently discovered /PSBT vulnerability in (CVE-2020-14199)

I hear bcashers are having a schism over whether to hardfork every 6 months or every 9 months.

Going to have to side with the 6monthers:

If you make it every 9 months, then babies conceived celebrating hardfork N will put the women in the hospital for delivery right when HF N+1 is activating, reducing manpower by half if something goes wrong...

The technology does not exist today to verify an implementation is faithful to a specification.

Due to the nature of consensus systems, it is necessarily the implementation that is authoritative.

To compete with Core, fork the consensus code.
Anything less is likely buggy.

Please ensure it matches the key you already have, and/or otherwise verify my key fingerprint from at least a few sources!

The severity of this may be exaggerated:
Since this vulnerability can only be exploited by tricking the user to sign twice, there's a fundamental unfixable attack here anyway:
If they can trick you to sign twice, they can probably also get you to send the full amount twice too.

Bug in , which can be a security vulnerability for hardware wallets and similar.
isn't vulnerable itself, but users of Segwit wallets should ensure they upgrade if affected, before *sending* any new transactions.
(The solution is to not use a new technical-internals feature Segwit introduced.)
