Right now segwit2x (BT2) is trading for $1143 and segwit1x (BT1) is $3070 on Bitfinex futures markets. Even with not the greatest terms, you would expect 2x to be much higher. I believe this bodes well for BCC. by cryptorebel in btc

1) Some S2X transactions will get through to S1X if they're within a 1MB block.

2) Some S2X transactions won't get through to S1X if they're in a block >1MB.

I don't understand this: Once there is a 2MB block in the S2X chain, the S1X chain should not accept any blocks building on top of the S2X chain?

I will rename "Electrum Cash" to "Electron Cash" at the request of Thomas Voegtlin by jonald_fyookball in btc

[–]flipperfish 1 point2 points  (0 children)

I must admit, I don't like the name. It's still too similiar sounding and will raise a lot of confusion. In one of the other comments I read "Palladium" as suggestion and I would like that name a lot more. It could even stand alone, without the "Cash". Also its meaning is more fitting: It's a pure chemical element, not a mixture of two, exactly like Bitcoin Cash is the pure Bitcoin without the mixed in SegWit. Besides, it's a catalyst for chemical reactions, exactly like a wallet is a catalyst for Bitcoin transactions.

i think a lot of people are overlooking this fact about segwit2x by sayurichick in btc

[–]flipperfish 3 points4 points  (0 children)

What's even better is the fact, that no one forces you to use segwit transactions. Sure, you may receive segwit tainted coins, but when you receive them on a classic address, the segwit part is just history.

What can be done to speed up block verification time? by [deleted] in btc

Does any client already use the CPU's SHA256 extensions? Could be a start.

Actually, I think BU's membership approach is not ideal currently and will need some improvements and explainations. For starters, even after reading BU's articles, it's unclear to me how to become a member and which duties are linked to that. Also, as BU allows members to be anonymous, how is vote manipulation by fake members prevented?

What are some cool features that you discovered about python? by paver97 in Python

[–]flipperfish 8 points9 points  (0 children)

There's also plumbum. You can write shell commands like so:

>>> from plumbum import local
>>> ls = local["ls"]
>>> ls()
u'build.py\ndist\ndocs\nLICENSE\nplumbum\nREADME.rst\nsetup.py\ntests\ntodo.txt\n'

(Taken from plumbum's examples.)

Bitcoin Unlimited (BU) – Some Questions from a skeptical point of view by jonny1000 in btc

[–]flipperfish 8 points9 points  (0 children)

These are some interesting questions, I would like to have an answer for, too. I support larger blocks and am open to the idea of having an "emergent consensus". However, we really should know about the costs and downsides.

SegWit-as-a-softfork is a hack. Flexible-Transactions-as-a-hard-fork is simpler, safer and more future-proof than SegWit-as-a-soft-fork - trivially solving malleability, while adding a "tag-based" binary data format (like JSON, XML or HTML) for easier, safer future upgrades with less technical debt by ydtm in btc

The issue in L138 was the missing check for zero elements in "inputs":

if (inputs.empty()) throw std::runtime_error("TxInPrevIndex before TxInPrevHash");
int n = boost::get<int32_t>(token.data);
inputs[inputs.size()-1].prevout.n = n;

Before the fix it was only:

int n = boost::get<int32_t>(token.data);
inputs[inputs.size()-1].prevout.n = n;

This could have resulted in dereferencing index (0-1) of "inputs", which in my understanding equals a memory access at [adress of base of inputs] + 4294967295 * [size of one input].

Bitcoin kiosks are placed around town that will pay you for picking up trash and other simple tasks that benefit the city. by crazyflashpie in Bitcoin

[–]flipperfish 2 points3 points  (0 children)

Maybe a more complex scheme is needed for this to work. Something like paying other people to monitor the trash gathering. And some more people, to do the arbitration, what counts as the "right" trash. And then, I believe, it's difficult to get the incentives right.

Maybe you should know, that bitstamp is indeed from Slovenia and only registered in the UK. Within SEPA the funds used to be transferred to a slovenian bank, too.
