Ya, I've been using side-chain for a while now. Super functional! Highly recommend!

Sideripple.  You mean sideripple.  There are no sidechains anymore (never were).

Of course, this makes the whole system far more needlessly complex and far less secure than a coin that just uses one chain (since it relies on merged mining with very dodgy security assumptions).

Sidechains are not mined.  They can only replace centralized coins like Ripple (SideRipples?).  It was announced here today:

Quote
security for the blockchain is provided by a set of predefined functionaries in an arrangement called a Fed-Peg. The sidechain does not include mining or proof-of-work at this point.

At one point in the past people hoped there would be some magic way to have truly decentralized security without a new source of scarcity to incentivize new forms of mining, or that there was some way to have decentralized security without mining -- but it turns out there wasn't no such thing as that particular free lunch.

Some "Altcoins are soon[tm] to be obsolete" Fudders

All the proposals for non-centralized sidechains had massive holes poked in them and collapsed.  Now even the sidechain originators have abandoned that goal.  So sidechains really aren't an alternative to altcoins anymore.

There are still a lot of redittards and shills chirping last week's Blockstream propaganda, but make no mistake: 08-Jun-2015 was the day when "sidechains are coming" mattered.

I showed the paper to an ASIC designers and the reply was:

That is not too surprising.  Most self-identified "ASIC designers" can't handle domino design (it is a full-custom technique and not supported by "ASIC tools").  Haters gonna hate.

Intel, AMD, NVidia, and ATI all used domino logic exclusively for the critical path of all of their ~50nm-node chips.  Apple still uses it at 16nm, Intel has given conflicting information, and I don't know about the other two.

The links you quoted are in relation to SHA256, not Scrypt.

The PDF link is the one that is quoted and it talks only about Scrypt.

I think you've mixed up the designer's past accomplishments (SHA256 FPGA) and current project (Scrypt ASIC).

Wondering if people can provide any insight on how credible this is.  The figures are pretty out there, but on the other hand the guy (or gal?) behind it still holds the record for fastest publicly-released mining bitstream, verified by everyone who ran it in the FPGA mining days.  Dunno.  Credible?  Claims to use on-chip/same-die DRAM with no refresh (!?) since the data doesn't need to stick around long:

Quote
At foundry-recommended voltage the silicon needed to generate 1Mh/s costs $0.98 and consumes 6.4W. The circuit can be undervolted to consume as little as 1.44J/Mh (W/Mh/s) at 252kh/s. There is plenty of headroom for overvolting. Bear in mind all of these numbers are for 50-70nm processes; on a 28nm process the power is cut roughly in half and the price per Mh/s drops by a factor of 4-8.  All performance numbers use real inputs and full taped-out layout parasitics. Quoted performance figures do not include any time-memory tradeoff (TMTO).

69  Bitcoin / Bitcoin Discussion / Re: Can we talk about removing SSL from the payment protocol and put PGP? on: April 09, 2014, 11:36:04 AM
I think PGP would be better than SSL

You can talk about it all you like; the devs will just ignore you, like everybody else who told them this.

The payment coin tracking protocol's use of SSL CAs has been a suicidal idea from day one.  The non-excuse proffered is "yeah but the CAs are the best of a lot of bad solutions".  Guess what folks, if all the solutions are bad then maybe the problem isn't actually a "problem" and doesn't need solving.

Or more specifically, as in this case, you aren't solving a problem you're just hiding a problem (invoice authentication) behind a much harder, much more-unsolved and probably-never-solvable problem (general purpose PKI) so you can piggyback off of the excuses crafted by the probably-never-solvable-problem's non-solution vendors.

General-purpose, worldwide, universally trusted PKI will never exist.

Tossing your lot in with the "most popular failed attempt" at solving this problem is much, much worse than admitting that nobody knows how to solve this problem and secure systems shouldn't be based on the assumption that it can be solved.

If you ever used the payment protocol (you clicked a bitcoin: link and saw a green box in Bitcoin Core's send dialog), then you should consider your wallet to be compromised.

At least two dozen people (and I was nowhere near the first one) told the devs that using the OpenSSL CA infrastructure for their "payment protocol" coin-tracking fantasies was a (a) crazy, (b) stupid, and (c) risky scheme that involved an utterly massive expansion of the attack surface to include all of SSL and the entire certificate authority ponzi-scheme.

What did they do?  They ignored common sense.

The bitcoin dev responsible for this idiocy is totally incompetent and should step down effective immediately.  Oh wait, that happened.

Carry on.

I dont recall you buying from me, but ill answer it anyway to set thighs straight.

Different bitcointalk account.


The cards i sell defiantly convert with a 2.8% surcharge automatically.

Right, that's why I was surpised by the 6.5% fee.


It must have gone through an intermediary bank, which put a hefty surcharge on the transaction.

SEPA transfers cannot have "intermediary bank" fees and the surcharges by banks are very tightly regulated.


It must have
Please inquire at the hotline(back of the letter, they speak English), why this has happened.

I tried using their secure messaging form (when logged into the website).  No response. =(

Hi, I have one of the USD cards and needed to load it using a withdraw from BTC-e.  I figured the most sensible way to do it was to use SEPA.

I withdrew EUR 2600 from BTC-e.  They took their 100EUR fee (ouch, I know).

So I expected about 2500EUR = $3446 - 2.8% = 3446 * (1.0 - 0.028) = $3349 to show up on the card.

But only $3223.01 arrived.  That's a 6.5% fee!  What happened?

Has anybody else tried using SEPA to load a USD card?

I'm going to do all the spending in USD so I figured getting a EUR card would end up costing the same; I'd just pay it when I spent it instead of when I loaded it.  And it's easier to keep track if the fee is charged all at once up front.

Thanks.
73  Bitcoin / Bitcoin Discussion / Re: Is the hacker's name in _House of Cards_ Season 2 Episode 17 a coincidence? on: February 15, 2014, 09:39:31 AM
It was also mentioned in S02E01 when one dude was explaining to another dude what the "dark web" is.

That's what I meant; for some reason the episode numbers don't reset at the start of the season.  And props to the director for calling it the "deep web" instead of the "dark web", although having "bitcoin" wind up in the same sentence as "child porn" was kinda unfortunate.
74  Bitcoin / Bitcoin Discussion / Is the hacker's name in _House of Cards_ Season 2 Episode 17 a coincidence? on: February 15, 2014, 07:37:19 AM
... or perhaps a subtle reminder that monkey wrench hacking can be done with deferred prosecution agreements instead of wrenches.

FWIW, bitcoin was mentioned in episode 16.

I wouldn't trust much from Kapiton at all. People are having issues withdrawing both bitcoins and funds from there atm.

Yep, Sebastian ran off to Venezuela with all the customers' funds.  Very sad.
76  Economy / Economics / Re: BTCUSD bid at $9893 on Kapiton.se on: December 13, 2013, 08:50:31 PM
a bid that much overvalued looks a little fishy, no?

Thank you, captain motherfucking obvious.
77  Economy / Economics / BTCUSD bid at $9893 on Kapiton.se on: December 13, 2013, 07:49:43 PM
Check it out, bids on the order book at 65754 SEK per coin:

http://bitcoincharts.com/markets/kptnSEK.html

verified on kapiton's website.  That's almost five figures in USD.

Can you say "meltup"?

Douchebaggery like this is what's holding back bitcoin.
