if so ill remind my great great great great great great grandchildren to check in on your great great great great great great grandchildren when they inherit your project after we both pass away and have been rotting for a few centuries

quantum theory
quantum mechanics
quantum computing. is all about quanta

in short once you pull away the big science buzzwording. its the simple fact of... more options.(quantity quantitate)

quantum theory can go so absurdly irrational that quantum theorists would think that it was ok to escalate the amount of options of Schroedinger cat to hypotheses that while in the box an asteroid can enter the earth's atmosphere and cause a sonic boom which echo's inside the box and scares the cat into having a heart attack so the chances of death are higher.

thats just one example of where trying to bring quantum theory into a debates can end up going down an irrational rabbit hole.

as for me taking the opportunity to meander an already meandered topic even further off topic(of collisions) i tried to redirect it back into the realm of other conversations in other topics (bitcoin based, not cat death based) to explain quantum computing.. seeing as this is a bitcoin forum and more people care about quantum theory in regards to bitcoin, rather than a cat

lastly i said mythical
meaning a myth a theory a story.
anything is a myth until it is busted.

i prefer science fact when dealing with current and future tech. and although quantum does open up more options, sticking to rational and practical idea's without doing deep into a rabbit hole of absurd possibilities is what i try to keep to

i would say blockchain.info is a service that does do what you want. but just be sure to back up all the keys/seed you use, incase the website goes down
and use a REALLY LONG password/phrase(avoids hackers getting at your keys/seed).

but back up the keys/seed in several locations. as the funds are linked to the keys/seed not the services password. so the private keys/seed is the most important thing to keep safe

centralised webwallets(where they hold the funds on THEIR keys) are usually best only for daily spend amounts. like what you would spend on a few days groceries or a fun night out amount.

own use private key/seed webwallets are more like a few weeks/months wages.
home PC downloaded litewallets for larger amounts
hardware wallets for life changing amounts

but always backup the key/seed

the more you hold the more cautious you should get.

coinbase does not give users private keys.

just like all other exchanges
when you put funds in. they all belong to coinbase/other exchanges.
you are just given a mySQL database "balance" and that is it.

should they shutdown you lose.
should they get hacked. they will try to convince you that you lost funds (even though they lost funds)

its like a bank where you need to ask them when you want some funds and they can authorise a withdrawal to you, which is more of a moral contract.

this is why its best you store funds in a wallet that gives you private keys so that you are in sole control of the funds and not having to rely on third parties morals/ethics

no quantum theory is not that mythical
if you wipe away non descriptive buzzwords like super-position and think rationally. its simple.

its just opening up the idea that things are not black and white, on or off, dead or alive, binary..  .. not 2 options
its meant to open peoples minds to more options.

yea some people go absurdly beyond the rational because they think the quantum theory allows them to think irrationally. but thats not what its about.

Schroedinger cat is in the state of dying.. there is a chance of saving it by opening the box early. or waiting longer where the chance it dies is higher.

like hospitals. when someones heart stops.. they are physically dead.
but doctors do a 'code blue' and run to the patient saying the patient is dying. and try resuscitation the patient. its only minutes later do doctors declare the patient is dead, even if his body gave out minutes earlier

like hospitals. when someones heart is working.. they are physically alive. but have multiple cancers and in extreme pain
so doctors say the patient is dying. and discuss euthanasia as a humane option. its only minutes later do doctors declare the patient is dead, or alive depending on if they euphanize or not

what you see and think may be different to reality so things are not as black and white as alive and dead. on or off, theres always a grey area in everything.

quantum computing is not some outer space wormhole, time twisting theory.
its simply instead of using the old binary 2option switch.. its using more than 2 options.
eg
its not 0v=0 or 1v=1..
its 0v=0   0.33v=1   0.66v=2   1v=3  its as simple as that.

its about if and maybe.. aswell as yes no / on off / true false

agreed.

im still laughing at the utopian dream of hedging against fiat but measuring it in favour of fiat..

i hope soon exchanges start measuring bitcoin in "cost of living index" which is more of a international metric that is more tied directly to goods and services where the fiat valuation is secondary

yea it speaks with a few people.
mainly gavin andresen.. seems like not the latest interview video
bit of erik voorhees

others are talking but they are not prominent names.

just came across a documentary about bitcoin
called "banking on bitcoin"
cited as created 2016

sorry if this streaming site gives a couple annoying pop-ups. most sites do these days
if anyone can link a less annoying site, ill list it
https://123movies.cloud/film/banking-on-bitcoin-18789/watching.html

review
interviews with lots of people

mentioned everything from cypherpunks, a bit about how bitcoin works (no big technical detail, so noob friendly)
mtgox, silkroad, bitinstant, VC's jumping in, bankers starting altcoins. and a few speculations on who is satoshi

summary fair 50/50 unbiased. mentioning major events and history of bitcoin

facepalm

dont call out foolish numbers

lauda as not only a moderator, but as a sig campaign organiser yourself. you could and should just report him to his sign campaign manager and lose him his earning status. that would shut him up
...


a trillion pass phrases. thats only:
9 alphabet characters deep
8 alphanumeric characters deep
7 alphanumericsymbol characters deep

the funny part is. that the 1mb limit was used to help restrict data being transmitted.
if pools are sending out say 4mb of data(cores 4mb weight concept) or 40mb(video's 50k tx concept). then there is no need for the 1mb base rule.
because now the 1mb is not used to limit data/bandwidth. its just limiting old transactions utility/ability to be accepted

also keeping the 1mb base rule but then having 99.99% of tx data outside of the block makes the real data being moved (for 50k tx) something like 40mb of real data..
the only reason to keep the 1mb base would be to prevent people who just want to do old(legacy) transactions.
thus forcing people to move funds to new funky keypairs/transaction types because their old legacy transactions wont get accepted into the base block any more (unless paying a HUGE fee because their 400byte legacy tx is the equivalent to 40 transactions of the new funky style)

keeping the 1mb base rule is more of a controlling the community while directing them down a certain road. rather than any bandwidth limitation security.

the guy doesnt understand the realistic workings of quantum.
binary logic problems would be solved by quantum computer of matching hertz at a 2x rate.

bitcoins PoW has so many hertz that are specifically dedicated to only doing one task (hashrate) that it outpaces a quantum computers at a CPU hert comparison by about 100,000 per asic unit and the network has atleast 130,000 asic units to produce one result every ~10minutes.
so quantum computers need to have 130,000,000,000 more hertz than a common binary PC. which isnt gonna happen any time soon.

more than likely. MANY people will individually make/use quantum asics to distribute and protect the network before one person can accumulate enough to hurt the network.
EG. did nvideo kill off bitcoin back in the GPU days?? nope they sold cards individually to users rather than accumilate their own farm to destroy bitcoin.
did antpool kill off bitcoin back in the first asic days?? nope they sold individual asics to users and kept their farm at reasonable levels

secondly... back to the hack-ability via quantum..
its non binary problems. such as vectors (ECDSA) that quantum computers of matching hertz can solve at a metric of 65,000x rate.

i envision when the keypair curve changes we should not be restricted to one curve, thus mitigating the brute force chances by having more variaty as a defence
eg. instead of everyone picking random coordinates within y² = x³ + 7 one person may have an address that starts
1xxxxxx... which equals y² = x³ + 7  is used
2xxxxxx... which equals y² = x³ + 8  is used
then for instance
4xxxxxx... which equals lets say y² = x³ + 9 is used
6xxxxxx... which equals lets say y² = x³ + 10 is used

or where
1xxxxxx...7(appended to end of address) which equals y² = x³ + 7  is used
1xxxxxx...8(appended to end of address) which equals y² = x³ + 8  is used

or where it may not even need to be y² = x³ + x at all. we can have a huge array of different variables.

thus making it harder for a brute forcer to find all possible combinations, because the elliptic(map) and then resulting fibbonacco(private key) curves would differ
many users have multithreading versions of bitcoin so the whole linear/quadratic processing time has been a laughing stock due to lack of actual regular transactions that needed alot of processing. but should someone malliciously continue making endless blocks of large sigop tx's then multithreading has its advantages, the whole linear/quatratics issue can also be mitigated by just limiting sigops per tx.. or mitigated if segwit is activated (but then thats just a call to war for malicious users to try large sigop tx's to delay old legacy clients)

i personally would not be using unixtime. i would be using blockheight instead.
so should others

miners do include tx's..
but.
here is the explanation of 'empty blocks'
when a block solution occurs the old method is:
to receive all that block data, verify it then verify the solution is also correct. then look at what tx's are confirmed in that block to know what transactions not to include in your next attempt at the next block. this can take upto a couple minutes.

when a block solution occurs the old method is:
instantly start a new empty block hashing while you waste a bit of time verifying someones solution. when confirmed, add unconfirmed transactions to your active attempt.
the thing is some blocks have luck of being solved in just a couple minutes and so thy have not had time to fill the blocks.
the logic is.. while your verifying a solution. why bother powering down your asics and twiddle your thumbs doing nothing for upto 2 minutes

to correct the person 2 posts ago

on a consensus activation. any bitcoin client is still on the same network. just more or less involved in seeing orphans as often.
its the same network but the data each side has, temporarily may differ for a certain time.

its an intentional split (actually blacklisting opposing nodes and not using consensus) that would be on different 'forks/networks'(altcoins)

---

on a consensus activation
orphaning kills off and drops the minority block that doesnt meet the majority rule. meaning one minute a block shows up with a list of transactions. next minute that block of transactions is gone and another block is in its place that meets the majority rules, picking up those lost transactions (as they are reclassified as unconfirmed until added to a block) either in that new block or another block soon after

hense why in the beginning of an activation of any fork, soft or hard there is an orphan risk so most merchants will wait a few extra confirms to wait and see if a block gets dropped off the chain or not.

most pools drop 1-2 blocks a day-week. and although 1confirm (under 1.44% chance of orphan) is enough for todays rational trust.
in a 95% risk waiting 6-15 confirms(5%-10%) could become the extreme waiting times for confirms.

worse case scenario (doesnt really happen but should be wary of)
during the risky time there are chances of double spending IF a merchant accepts a payment but then its dropped, and that transaction is not then re-confirmed on the replacement blocks (super low chance of happening. as usually pools would re-add the now unconfirmed tx to a new block, reconfirming it, thus giving the merchant the funds eventually)

and (although no one is proposing this) a 51% activation. merchants would wait 12-24 hours(72-144 confirms) due to the mass orphan drama such a low threshold would cause

as for making an altcoin, (different forks) this requires something extra.. actually blacklisting and not connecting opposing nodes.

as long as you have full access to your private key to import the keys to another service should the one you use stop operating. your fine.

but if you start getting to a point of holding enough value that it would hurt you to lose, then you may desire the independence of running a full node

if 2 people have an cat (same address) in a box (wallet address pool of 20-100 addresses yet to be used) but cannot yet see if its an active address ready to jump out and walk around (collide and be spent by other person) or not.. ...  have they yet collided..

my point is that you can never know until you do something.

---

general point to everyone

but to avoid the risks, things like random numbers/wallet seed/private key entropy should be high to avoid the chance.

assume you have the best random entropy that exists today
the chances of you choosing a specific address someone you know already has, colliding with you and/or you finding that same specific address is
2 out of 904625697166532776746648320380374280100293470930272690489102837043110636675

however the chances of a random collision with a random address is
a few million out of 904625697166532776746648320380374280100293470930272690489102837043110636675

if randomness does not produce a random factor of 75digits.. then your not grabbing a private key from the fall allotment of possible keys

EG if randomness was only between 0-200
then it will only produce 200 keys before repeating (colliding) with keys its already produced

EG if randomness was just an 8 character (alphabet only) brainwallet password
then there will only produce 208827064576 keys before repeating (colliding) with keys its already produced

---

there has already been many brain wallet collissions. so yes collissions have happened and will happen
there has already been a few bad RND collissions. so yes collissions have happened and will happen

but to ensure the chances of you colliding. can be mitigated by having a 75 digit random factor to maximise the pool of addresses you can randomly land on

so here it is the last 8 years worth of data
yep thats right 8 years of international financial transactions, fitting on the same size as a fingernail.


as for is it worth it for yourself.

well its more like a hive mindset. if everyone does their part it helps everyone out.
however if the value of bitcoin you hold is not life changing for you, then you wont notice or need to worry much about changing your life.

id say the more bitcoin you own and afraid of losing the more you should consider running a full node

schrodinger's cat

if you cant see it, did it really happen?

anyone on for instance the american foodstamps debit card able to explain how this is administered. where its not meant to be allowed to 'cash out' and only meant to used to buy 'healthy foods'.?

do the social security office penalise foodstamp recipients by knowing whats bought. or is it up to the retailer to refuse service if someone using these unemployment debit cards if asked for alcohol and cigarettes using the card

i only ask as an example of a dystopian future where in a cashless society if alcohol prohibition was to return. how it would be stopped or worked around.

i already seen news of america not allowing deadbeat dads to renew their car licence/registration if they are flagged as not paying child maintenance.

until a trojan horse key logger see's what you type in



im not having a go at you personally, im more so expanding beyond your own precautions to make people aware of the weakness of each precaution. thus helping people experiment with putting valuable data in more than just 1 or 2 places

giagabytes.. dont be a loony.. stick to rational and reasonable numbers

the community are saying 8mb are safe.. but compromised to 2mb just to settle the argument december 2015. which the community thought they had settled when core announced segwit mid 2016 and dynamic blocks mid2017..(december2015 consensus roundtable and roadmap)

core have even mid 2016 said 4mb is safe. and cough/facepalm unofficially said they havnt agreed but will do a change to the base block size
but even now refuse to actually raise their base block above 1mb and have no signs of actually doing real base block dynamic sizes beginning at 2mb ...

so everyone is stuck at 1mb fixed base block

thats an american mindset of "$0.20 is ok" you do know 20cents is like 4 hours of minimum wage labour in a few developing countries.
and you wonder why developing countries are not storming into bitcoin.

yea 20 cents is only 1minute 36 seconds of american minimum wage ($7.50) but try to put your mind into the mindset of the 'unbanked' countries that will actually see/want real benefit of bitcoin

bangladesh 9 cents an hour Min wage: 20cents= 2hours 13minutes
congo 20cents a hour Min wage: 20cents= 1hour 0 minutes
cuba 5 cents an hour Min wage: 20cents= 4 hours 0 minutes
Eritrea 15cents an hour Min wage: 20cents= 1hour 20 minutes
Ethiopia 11cents an hour Min wage: 20cents=1 hour 50 minutes
Gambia 15cents an hour Min wage: 20cents= 1hour 20 minutes
Georgia 5 cents an hour Min wage: 20cents= 4 hours 0 minutes
Guinea-Bissau 18 cents an hour Min wage: 20cents= 1hours 7minutes
Kyrgyzstan 9 cents an hour Min wage: 20cents= 2hours 13minutes

screw it ill stop at K of the alphabet of countries on low income, you can research the rest

if you think in the mindset of developing countries and then translate it back to american...

would you pay between $7.50(1hr) to $30(4hr) to use bitcoin.. emphasis thinking about it from the minimum wage prospective
