@business To be clear, I am *not* an investor, I am an engineer. I don’t even own any publicly traded stock besides Tesla.

However, when fiat currency has negative real interest, only a fool wouldn’t look elsewhere.

Bitcoin is almost as bs as fiat money. The key word is “almost”.

So @BNYMellon said Thursday it will hold, transfer and issue bitcoin and other cryptocurrencies on behalf of its asset-management clients.

Oh dear I do believe you are going to have a hard time with the bitcoin issuance aspect.

@kriptoemre @LinaSeiche Might want to redact that number a little better...

This is implicitly answered in chapter 7 (the ScriptSig is a signature over an entire transaction, so would not be usable in a different transaction).

[djnicholson @djnicholson]

@jimmysong Question on #ProgrammingBitcoin chapter 6: What stops me from extracting the ScriptSig from an unconfirmed transaction and using it to construct a malicious transaction that spends the UTXO to a ScriptPubKey that I control? (Great book BTW!)

@jimmysong Q on #ProgrammingBitcoin ch 5: The number of outputs is encoded as a varint (< 2^64) but the index in an input is 4-byte (< 2^32). Why the discrepancy? Doesn't this create a theoretical possibility of an unspendable output (albeit as part of a *massive* transaction)?

Not your keys not your Bitcoin. But, giving users their keys is not enough.

Me & @J9Roem drafted this repo of wallet specs. Users should not have to dig or read the source code of a wallet to figure-out the Derivation Path or Redeem Scripts. https://t.co/QrZSx5py97

It's very interesting watching all this drama in the media about FaceApp just because it's run by a company in Russia, yet no one has a problem uploading all their personal photos and videos to Twitter, Snapchat & Facebook.
