no they werent

many of us early adopters were following your endless rants and your drug induced paranoia and in the end we came to the conclusion you get drunk/stoned some nights, think up some epic story of no relevance and then want to entertain the world with your rants.

please either go to some drug support group, or set a long password for your computer login so that you have to think rationally before typing anything.

most of your posts belong on the sci-fi section or the crime drama of some story telling website.

many people have come to the conclusion you are high when you post your nonsense, so take it as a hint

You keep talking about facts of which none are ever presented. Can you please list your facts below as to why SegWit is necessary?

Have you ever heard the phrase "If it ain't broke don't fix it?"
1) It is broken. TX malleability is a existing vulnerability. I don't expect you to be aware of this though.
2) If we follow that 'phrase', the same can be said for increasing the block size limit.
2.1) The same can be said for anything proposed by Classic (FlexTrans) & BU (random 'improvements').

lauda.. do you even understand malleability.
and how it is not a problem in multisig, and how RFB CPFP are the replacements for double spends. meaning malleability is not a big deal, because solving malleability solves nothing.

its been an 'issue' but not a big deal problem... after all ~2000-2500tx every ten minutes for the last 2 years have had no massive complaints/problems. the only time it was of any drama was a couple years ago when kerpeles used it as a fake reason to embezzle funds and blame bitcoin.

even the latest exchange embezzlings, which fake cried hacks didnt use the malleability screams of lost funds, because they know people would laugh at them because of the obvious fake excuses if they did blame malleability

wake up and research. learn that people have found work arounds and ways to double check and reduce risk

its time you spend less time being spoin fed on IRC and instead do your own independant research
18984  Bitcoin / Bitcoin Discussion / Re: We need an incentive to make first world population use Bitcoin on: December 31, 2016, 10:17:18 AM
HELLO
wake up

advertising bitcoin is not the problem.

using bitcoin is.
it needs to be simplified!!
even hardware wallets need to be revamped. the issue is that it is too cumbersome, complicated and needs downloads/browser extensions or server access.. plus needing to copy and paste lengthy gobbledegook addresses and decimal numbers

but there is a solution, should someone want to do it.
SMART WATCHES/FITBIT wristbands



advantages
no software touches the device
private keys remain hidden
the device is wearable (new fashion craze=popular)
making a tx is as simple as shaking your wrist
no need to understand the mechanics of bitcoin to use it

just google "programmable smart watches with NFC" and you'll see the tech is available.


barclays are ahead of the game. first they are doing it with their native fiat payment method,
https://www.shop.bpay.co.uk/categories/buy-bpay/product/wristband/wristband


but barclays is knee's deep in hyperldger so next will be a hyperledger wristband, which will make hyperledger (bitcoins altcoin(banker) competitor) appealing to people that are not paranoid geeks
18985  Bitcoin / Bitcoin Discussion / Re: (RE: Exchanges hack) Let's talk about a solution before instead of crying after on: December 31, 2016, 09:19:06 AM
the shapeshift model wont work for daytraders.

Having thought about it, I suppose the same potentially applies to ACCT, depending on which currency it is.  Transaction directly on chain tend to involve a miners fee, which (in BTC at least) is usually slightly higher than the exchange's buy/sell fees.  In that regard, ACCT would be better for one-off trades as there's literally zero counterparty risk involved.  But for frequent trades (daytrading) the exchanges would be more profitable, so your multi-sig proposal would be a significant improvement.

If scaling ever gets sorted, I sincerely hope the next big priority is ACCT.

this is why litecoin, vertcoin and other alts are also doing LN. so that a future LN client can interact with many coins and swap independently and settle on all blockchains at a later('withdraw') time.

but all LN concepts at the moment still have flaws, so its too early to tell
18986  Bitcoin / Bitcoin Discussion / Re: (RE: Exchanges hack) Let's talk about a solution before instead of crying after on: December 31, 2016, 09:14:20 AM
but also that is going to make things complicated.
lets assume you want to make a trade, you have to do all the signing,... and specially if you are keeping things in cold storage, that will be harder (time consuming) and time is sometimes important in trading with volatile prices.

the individual public keys used to form the multisig are empty of value. thus no need to 'coldstore' exactly.
because they are separate, that alone is a line of defense

because multisig involves dual signatures. an exchange via API can sign the tx(not on the front end) send the signed tx to the front end and then the front end sends the signed tx via api to the customers LN/multisig client.
thus the private key is not on the front end and transmission time is miliseconds (think how proxies work)

knowing the customer needs to sign too. the customer would refuse to sign if it noticed the destination of funds were going elsewhere. thus a hacker cant intercept. and also a hacker cannot change the destination after signing because the signature wont match the tx's new content.

lastly the customer just sends back a copy with their signature, thus also protecting their own private key by not having to use the privatekey within the exchange front end. but only on their own personal computer

also the first thing that came to my mind was confirmation time, but i don't think confirmation is necessary since it is a multisignature transaction and neither party can double spend, right?
because tx's are using real unspent funds and double signed it cant be double spend because funds cant move without both sides agreement.
and thus its no need to broadcast it to the network instantly. just holding a tx becomes like a bearer bond/promise/guarantee to pay.

i am not familiar enough with LN though, but from what i have read it seems like it can be good in this case as long as there aren't that much additional fees.

current LN concepts do have MANY 'penalties' so although you can re-sign thousands of tx's at an agreed lower fee per re-sign. LN hubs want to introduce other ways to make money, hold funds and revoke funds. so LN has some faults.

hense why im more interested in traditional multisig utility which has been built into bitcoin for along time now. but lets hope the LN concepts aimed at repaying blockstream investors is not so heavy handed with its penalties, otherwise LN will be impractical
18987  Bitcoin / Bitcoin Discussion / Re: (RE: Exchanges hack) Let's talk about a solution before instead of crying after on: December 31, 2016, 08:57:31 AM
the shapeshift model wont work for daytraders.

but multisig/LN would.
this is because instead of seeing some mysql 'balance' you are seeing a signed tx of real unspent bitcoin value between you and an exchange and shows who owns what share of that value.
EG
[in: 1cU5t0m3r: 1.0btc]
[in: 13xCh4nG3: 1.0btc]
[out: 1cU5t0m3r: 0.999btc]
[out: 13xCh4nG3: 1.001btc]
[sig: 1cU5t0m3r]
[sig: 13xCh4nG3]

and that tx changes and gets resigned when a customer places an order (example below of placing an order for another 0.001btc)
[in: 1cU5t0m3r: 1.0btc]
[in: 13xCh4nG3: 1.0btc]
[out: 1cU5t0m3r: 0.998btc]
[out: 13xCh4nG3: 1.002btc]
[sig: 1cU5t0m3r]
[sig: 13xCh4nG3]

when the customer want to 'withdraw' he just broadcasts that tx to the network to get confirmed
the exchange cant run away with 2btc because he needs the customers signature
the customer cant run away with 2btc because he needs the exchanges signature

so they both have to mutually agree on who owes who what and both sign to show agreement
18988  Bitcoin / Bitcoin Discussion / Re: NOT Upgrading to SegWit who's with me?! on: December 31, 2016, 08:13:36 AM
They use outdated date to make it seem like Segwit brings only a little improvement for a 'lot of complexity'. Latest transaction pattern usage review shows that we can expect around 2.1 MB.

2.1mb IF 100% of people made 100% segwit versioned transactions compared to legacy transactions.
so 2.1mb is the best possibility. not the realistic expectation

its also funny that lauda has quietened down on the linear/quadratics debate now that i think he knows that an LN settlement is just a 2in 2out transaction. thus the amount of sigops is small and not an issue especially when an update to the libsecp256k1 brought a 5x efficiency gain.

lastly. LN relies on dual signing. so parties can check and double check the contents of a tx before signing to see if its able to malleate. thus by signing, the other party cannot then make another tx because it requires dual signatures. thus malleability is not an issue. they would refuse to sign a tx if it were showing the signs that the first tx was malleated.

im also laughing how core and their fanboys want to offset LN into the litenode category and then offer third parties to 'outsource' (paid to manage) the mainnet server connection to LN. where the manager has control to deploy revoke codes. and take a fee, impose a penalty
um hello. delayed spendability(AKA 3-5 banking day fund maturity/spendability (CLTV)) revoke codes (chargebacks (CSV)) and middleman management paid service(outsourced monitoring)...

LN has its utility but lets not kid ourselves. its just a 'banking' service that should be voluntary on the side.. not to be pushed as the end/only solution for bitcoin.

LN is not a permission-less, open, trustless system.
dual signatures = permissioned
outsourced monitoring = trust required

atleast be honest with yourself and sell LN on its real merits for the certain niches where it would be useful(exchanges, faucets, adsense, gambling). rather then overselling LN as the ultimate solution for everyone, while hiding its limitations and issues that will make it impractical for some people that actually dont want middlemen and locked funds managed with excess fee's/penalties, chargebacks and settlement delays.

LN is being pushed not for the benefit of bitcoin. but for the benefit of blockstream becoming the outsourced managers so that they can claim fee's and penalties to repay their investors.

no point upgrading.

after it activates then core will spoon feed out an actual fully functioning segwit release with full wallet functionality for segwit.

this 0.13.1 is just an empty gesture to make people feel like they are part of segwits desirability promotion. yet they are not part of the vote or veto power of true consensus.

18990  Bitcoin / Bitcoin Discussion / Re: Fucking Chinese - Part 2 on: December 30, 2016, 08:28:54 PM
Mining bitcoin is very profitable in china which explains why they have a largest share of hash power, because of how electricity is cheap in china , people are able to make profit out of mining bitcoin.

I study about energy and I know that in china they build a coal reactor every month ,so they can provide the electricity needs for the whole population.

its got little to do with energy costs

put it this way an asic in asia pays $225 electric per ASIC for 6 months.
in america its about $450

meaning only a couple hundred dollars difference spread over 6 months.

the real cost however is the ASIC itself.
because america doesnt make an asic they have to shell out $1500 per rig.
however it costs asia to make a rig just a couple hundred. so when they sell the rigs to americans. the asians can make many rigs. one to give america a couple to keep themselves and still some fiat spare to pay the electric for them couple rigs that cost them nothing thanks to the american consumer.

thus its pre profit for asia to mine. all because they make the rigs.. not due to electric costs

they talk about bitcoin the same way when its in the context of virtual currency

thats why when asked what i do. i just say im an international currency and asset trader, as my intro.
18993  Bitcoin / Bitcoin Discussion / Re: What are your good intentions regarding Bitcoin in 2017? on: December 30, 2016, 06:26:39 PM
I will build a bitcoin community in the area where I live. I believe the greater the bitcoin users it will assist in the development and improvement of bitcoin in the world. I want begin everything all over.

best advice.
start small.
dont hire big spaces out like a open space building for a year. start small like do a local meetup at a easy to find cafe /bar that is common place and doesnt require deposits or reservations.. like a small random one off social event. just to gauge/see how demand/popularity

then if lots are turning up and while talking you see there is demand for a regular large location to be needed then do it.

some people start at a bar where say 10 people turn up. then those people go and find a few others and the following week you book a night at a bar with a stage/(karaoke/mic night) area that can cope with 100, and you make it into a mini conference with speakers talking on stage. then you expand from there

if you already know of 100+ people locally that will want to turn up then skip the meetup and instead book a night at a place that has a stage and enough standing seating area, and then charge a small entrance fee to cover your costs for the night.
try not to get greedy with the entrance fee, unless it starts becoming a big event with lots of guest speakers and things happening
18994  Bitcoin / Bitcoin Discussion / Re: What are your good intentions regarding Bitcoin in 2017? on: December 30, 2016, 06:18:09 PM
More on Bitcoin awareness starting on the local community and hopefully word of mouth to reach more people, Most people mentality everything that involves money on the internet is a scam. changing the perception about bitcoins will be a good start.

3) PEOPLE need to realise bitcoin is code. it has no voice to promote itself and no arms and legs to defend itself, PEOPLE need to get involved instead of sitting on their hands waiting for bitcoin to do something.
EG if you want retailers in your area to accept bitcoin. go speak to them yourself
EG if you want to make bitcoin more popular. learn about bitcoin then set up some meetups/conferences
18995  Bitcoin / Bitcoin Discussion / Re: (RE: Exchanges hack) Let's talk about a solution before instead of crying after on: December 30, 2016, 05:44:52 PM
imagine old concept is depositing funds into your wifes account so that when you want to pay for something you need to ask her and its her that makes the payment. but she decides to run away with the milkman and your cash

imagine a new concept of a joint account where your wife cant run off with the milkman with all your funds, because she needs your authorisation to make payments aswell as hers.

1st of all, fuck milkmen. I mean seriously. They were obviously screwing everyone's mom. No wonder they don't exist anymore. Too many love-childs.

Anyways, with bank accounts you can have anyone can sign (ie 1 signature required) or everyone must sign (ie everyone on the account must sign). This is both in personal and business banking. Most joint accounts are probably anyone can sign though, but you do have a choice. It's definitely not a new concept.
Imagine this:

"Johnson!" Says your boss.

"Yessir!" You reply.

"I just got this $1,000,000 cheque that I need you to deposit into our business account that you're a signer for."

"I'll get on it right away sir!"

Deposits money. Withdraws $1million. Lives happy ever after in the Cayman Islands.


There's a reason this doesn't happen literally every minute of every day.

i didnt mean literally bank accounts. i was just putting multisig into a prospective common people understand. and yes in multisig you can have 1-of-2 also.. but then again in joint bank accounts you can also require dual signature where in multisig you can require 2-of-2

there are multiple purposes requirements you can set on a multisig and bank account.
EG child trust fund require both parents signatures and only unlocked at a certain date.
=2 of 2 multisig with a CLTV script

i only mentioned it as some people dont understand multisig/LN at its most basic use-case concept
18996  Bitcoin / Bitcoin Discussion / Re: (RE: Exchanges hack) Let's talk about a solution before instead of crying after on: December 30, 2016, 03:17:16 PM
if we want to starting trade bitcoin or altcoins putting our bitcoin to exchange is necessary to do so

imagine old concept is depositing funds into your wifes account so that when you want to pay for something you need to ask her and its her that makes the payment. but she decides to run away with the milkman and your cash

imagine a new concept of a joint account where your wife cant run off with the milkman with all your funds, because she needs your authorisation to make payments aswell as hers.

multisig is the new concept but i feel exchanges will wait for LN to be the 'tool' to make that a userfriendly process because at the moment trying to do multisigs is not 'granny friendly' in current popular bitcoin implementations
18997  Bitcoin / Bitcoin Discussion / Re: What are your good intentions regarding Bitcoin in 2017? on: December 30, 2016, 03:09:13 PM
heres some idea's what people can do this year

1) hardware wallets need a revamp. they need to function without needing to download browser add-ons or connecting to websites or things like electrum.
EG have software self contained
EG a fitbit/smartwatch with NFC to make payment just by swiping a retailers touchpad (and yes its possible, just not done yet)

2) nodes and wallets need more diversity. so far knots, blockchain.info, bitcoinj, greenaddress, core are all under the same 'ownership'

3) PEOPLE need to realise bitcoin is code. it has no voice to promote itself and no arms and legs to defend itself, PEOPLE need to get involved instead of sitting on their hands waiting for bitcoin to do something.
EG if you want retailers in your area to accept bitcoin. go speak to them yourself
EG if you want to make bitcoin more popular. learn about bitcoin then set up some meetups/conferences

4) bitcoin jobs. look for a product/service you think will be useful to sell. then look for suppliers/employee's/dropshippers and then start selling them for bitcoin.

5) exchanges should start requesting a public key and use the bitID concept for logins instead of passwords, and also use the public key to form multisigs to hold funds, instead of giving customers easy to fake mysql balances. thus mitigating hacker/insider embezzling risks
18998  Bitcoin / Bitcoin Discussion / Re: (RE: Exchanges hack) Let's talk about a solution before instead of crying after on: December 30, 2016, 02:38:58 PM
What about exchanges like ShapeShift? They don't hold your funds (not for long atleast) so if they get hacked, not much would be lost. Or is it just too impractical?

thats a coin swap service.

not a full day-trade exchange that handles fiat.

but lets play devils advocat. lets say full exchanges were to have been hacked.
this is because private keys are on the same front-end server as the users place orders.

this can also be mitigated by exchanges having a front-end with only publicly(deposit) keys and a 'command' database.

EG instead of the front end signing transactions, the front end puts a user withdrawal request into a database. and secretly a secondary system is checking that command database in seconds and processes it from another system. double checking the user actually authorised it.

the 'delay' is not stupidly a long manual process but a milisecond response time. just separated instead of combined into one system
though i would still prefer this separate system to use multisigs to not have 100% control of funds
18999  Bitcoin / Bitcoin Discussion / Re: (RE: Exchanges hack) Let's talk about a solution before instead of crying after on: December 30, 2016, 02:23:46 PM
I doesn't really matter what people here are proposing to reduce victims at the time exchanges get "hacked". People are too lazy and don't care as their behaviour didn't change a single bit after all incidents that we have seen. If you put decentralized exchanges aside, then the only possible outcome will be that exchanges store all their coins offline and thus get rid of hot wallets. It will annoy people as cashouts will be more time consuming as exchanges have to process everything manually, but at least it will have an immediate effect. But then again, it will protect you from hackers, but there are also the employees or the exchange operators that may turn out to be filthy thieves.

no no no

putting funds offline in exchanges full control is the problem.. not the solution

the solution is to have funds not be able to move without users authorisation.
by this i mean get rid of "passwords" stored on an exchange, because this is still giving exchanges/hackers control. and instead use a bitcoin feature built in since day one.. SIGNATURES


How would that work out since coins people deposit will get mixed within their system? As soon as you request a cashout, you'll get different coins than what you deposited. They don't appoint a certain amount of coins just for you where you can request a cashout and receive exactly these coins. I really don't see how exchanges are willing to change the way their system is set up. Every proposed change has to comply with the policies of the insurer (in case they have everything insured).

exchanges need to change

firstly
exchanges should ask their customer to register an empty public key. (emphasis PUBLIC)
the customer keeps the private key a secret.

next to log in users are shown a message. and the user has to paste in the signed message, to prove who they are.
that way 'passwords' are not saved on databases or involved because the message and reply(signature) is unique at each login.

next
the public key is used with a public key belonging to the exchange to form a multisig.
the multisig becomes the deposit address.

then when users want to make an order they sign a multisig transaction to give the exchange X of total balance. to place that X onto an order.
this way funds are made more so as a 50% user-50% exchange control of funds. and outside and inside hackers cannot take 100% control

in short LN will become useful for exchanges, because LN is about multisigs.
