Hi any help here would be appreciated.

I have a 2012 model macbook pro on which I (try) to run a full node signalling BIP148.

I store the data on an external hard drive.

I have the dbcache set to 1024MB, and the number of threads set to 7.

After about 4 minutes, the GUI starts to freeze for about 95% of the time. The synchronization with the network becomes unbearably slow, and I basically have to restart the node.

I consistently have 8 connections to the network.

Any help would be appreciated, later today I plan to set up a node on a RPi 3.

Thanks

edit: in the activity monitor, I can see that is stops using any CPU when it freezes.

i'm a noob but would appreciate an explanation here.

so my understanding with pub key crypto is that i send you my pub key, you send me yours. and the messages that we send to eachother which are encrypted are unreadable to anyone that doesn't hold the relevant private keys.

but what i don't understand is how this helps when there is a (wo)man in the middle "eve".

unless you exchange public keys in person eve could just be intercepting your messages and really you are both encrypting messages to eve's pub key and not the intended recipient and obviously she forwards it on, after having read the content and re-encrypting it using the correct public key.

i ask because i try to explain this stuff to people who know even less than me and realise i don't know what i'm talking about.

help a layman pls.

sorry if this has been done to death, but my core client (v0.11.2) has zero active connections and no block source available.

i'm running osx 10.8.5.

have rebooted, my internet connection is active. no vpn/tor.

i am at block 362048 (it's been a long time since i ran a node!)

help appreciated.

thanks

edit: i turned my VPN on and now it works. i am confuse :S

edit2 : the best i seem to be able to get is one active connection. is this anything to do with how much data i don't have? i.e people not connecting to my very out of date node?

Hi fellow BTCers.

Can someone please advise me on a service that has the same functionality as dropbox but is properly, and demonstrably (open source) encrypted?

I have a lot of data that is very important to me and would like upload it somewhere for safe keeping. I would also like it to remain protected.

I am happy to pay for the service, and would be delighted it they take bitcoin of course.

Thanks

edit: maybe a better way to explain what I'm looking for is essentially a storage device somewhere that isn't my house that I can download and upload to securely. I don't need a fancy interface or automatic syncing or anything. I just want to upload a large project when it is complete. That's all. As though I were to email it to myself, but we're talking 5GB files.

Seriously, how does this work? (When people are limited to carrying goods or currency in amount not greater than $10,000?)

Is it about "working-to-rule" for us BTCers and wasting (ours) and lots of immigration people's time by telling them that our money is effectively with us all the time?

Presumably, Satoshi used tor to post on this forum. Otherwise his anonymity would....well not exist.

I find it annoying how we have to pay to make use of this forum using tor, especially given what has led us here.

Hi, given the tech-ability of many of the users of this forum I was wondering if I could get some help....

I decided to share internet with my neighbour, so I want to put a router in his house and run an ethernet cable from my router to his.

What router should I buy? And it needs to have an ethernet INPUT that hopefully just works when I plug it in. I know how to set up the WIFI info, but if it's not getting internet I'm a little lost there.

Thanks,

S

Apparently in 2011 the collective CPU power of the planet was 6.4 x 10^18. I haven't been able to find an estimate of what it is now.

Just out of interest, if someone used every single computer in the world to mine bitcoin would they even come close to 1% of the hashrate of all the ASICs that are now being used? (In this hypothetical scenario, they wouldn't be able to make use of the ASICs that are all obviously plugged into host computers.)

Anyone got a critique of this, or have an article that would be of interest? Thanks

I, and many others here are hopefully opposed to the vile concept that is "intellectual property."

I would very much like to hasten its demise by making use of a massive, necessarily publicly used, consistent set of data: the blockchain.

I would like to store pieces of IP in the chain, thus making everyone who downloads it have to understand that technology is always political. Bitcoin is anti-censorship, let's demonstrate that fact.

There will be no way to use bitcoin (unless using lightweight clients) whilst accepting the unbelievably flawed logic spawned by the copyright cartel, something along the lines of "artists deserve to be paid for their work!" (which I agree with but not as an attempt at justifying censorship).

-ing previously determined thresholds?

I've been thinking about the ramifications of "programmable money," and am now wondering how programmable the currency itself is as opposed to how sophisticated the applications can become that can merely make use of information in the blockchain (though this is also extremely interesting).

I was imagining an automated salary/dividend payment type system in which a group can invest in a scheme, while a programmed BTC address that would be used as a companies only address for profit would necessarily pay to addresses agreed upon by the investors at the pre-agreed rate/time/amount/% etc. If - then - had anyone lost their private key can the address be programmed to give to a new public address in the event of a private key loss (this sounds just like multi-sig requiring m of n signatures, but with the extra requirement of some elements of the transaction already being somewhat set in stone i.e the addresses but not the amounts)?

This whole scenario would of course be contingent on the agreed upon address being used as the destination for profits/revenue.

I then think that how bitcoin interfaces with real world requirements that become fulfilled - and then somehow rendered digitally - is one of the most interesting aspects of designing the future.

To me bitcoin's deepest feature is its programmability. I know it is not what Ethereum could be if they overcome the technical challenges in front of them - and that this is deliberate. My question is, how programmable is it?

Having to make use of third party applications will be a compromise, but not the change of the world I think blockchain tech with a reliable and strong network really allows for.

The potentially anti-corrupting mechanisms that can be included within a transaction are mind-boggling, but how real they can be within the blockchain itself I am trying to fathom.

I've done a lot of rookie research and can't seem to understand what it is.

I've heard that it's turing complete, the html to bitcoin's http, an extra layer, NOT an alt etc.

Is it just 'BML?' (bitcoin markup language?)

How does it use and relate to the blockchain to do whatever it's doing that bitcoin isn't?

What does it all mean??

So my friend forgot his wallet password. Genius. 25 characters long, but something's not right. Tried a few hundred combos manually.

Question is,

Can I use my BFL 6.5GHz miner to crack it? How "S" are these "ASICs"?

It's checking hashes of sha 256 anyway right? Is it just down to software?

Thanks in advance.

22.1btc in the wallet.

2.2 BTC to anyone who sorts this for me.

edit: if we crack it that is! it's gonna come from his stash not mine! Let me get the address so you know where it's coming from...

edit 2: we know for certain what MOST of the password is. This is a typing error, not a completely loss of the password.

Ok so I have my paper wallet. (thank you community for helping me make this.)

I am confident in the security of the private key.

However, can someone give a fairly un-techy spooder a step by step guide on how to generate a transaction offline and broadcast it to the network?

I have no idea how, and I don't want to transfer it to a hot wallet, spend what I need and then send the remaining back to another paper wallet.

I have a laptop with linux and no hard drive I can use.

Thanks

(edit: if this has been explained to death already, please point me in the direction of the thread)

I assume it is well established that this is not possible or a question that would only be asked by someone with little technical understanding.

I'd just like to know why it's presumably not possible, because it would be a pain wouldn't it? Sending lots of useless information to the network? How can we rely on people only sending transactions to the network?

What don't I understand here?

Thanks.

edit: I'm not saying their useless info would end up in the blockchain, I'm just saying the nodes would have to deal with loads of spam all the time.

edit: get technical, I love it

For drivers living in NE/SE London.

For a few decades now the blackwall tunnel has been insufficient. Basically every day for hours these things are backed up.

Government will never improve on this, and it will only get more congested.

Cyrpto-tunnel?

Crowd sourced?

I'm sure this is a win.

I don't have the time to organise it though what I suggest to someone reading this is:

Go speak to the private company that made the Dartford tunnel. Find out what they did, where they went wrong, where they made good judgements.

Get backing.

Advertise.

This is something people want massively.

Find good locations for the mouths.

Come on - the cryptotunnel?? It's going to be the best thing ever.

Ok so the libertarians here will hopefully agree with me that Scotland should vote YES, and become free of the tyranny of the UK government. (Although this will likely result in another government being set-up - still though, the smaller the government the better.)

Whether they vote yes or no, we would love for them to adopt cryptocurrency.

If they vote yes they could adopt bitcoin, or perhaps "SCOTCOIN."

Can someone please make this alt-coin a reality please?

It seems like a currency people could use to show their rejection of Scottish "dependence." In the event of a "NO" majority (which is, unfortunately what will probably be the result) those that wanted independence could join together and reject the currency imposed on them

So I was inspired by the legend Andreas M anotopotoolousposuts to flip a coin 256 times and generate my own private key. I will use this as my cold storage.

How do I then hash the 256 bits of data into a private and then public key? Is it possible to do the maths without a computer at all? If not, is there some code I can run on an offline computer?

Thanks

He's a taxi driver and wants to accept bitcoin as payment.

What's his best option? He has an android phone, I was also thinking I could make him a paper wallet and have the QR code on his phone that people could make payments to, this being more secure.

What do you all advise?

Thanks,
