"blockchain" isn't really a technology, it's just a simple sequential file with linking between adjacent records.

Have you looked in your Bitcoin core data folder? It is not implemented as a sequential file there.

But I do agree that people should realize that Bitcoin is not synonymous as Blockchain. This is obvious from the fact that shit coins also use blockchain technology.

Show me just one link where there was a discussion of what I suggest here (but read at least the OP first and read it full)

https://bitcointalk.org/index.php?topic=332080.msg3571254#msg3571254

A lot of relevant discussion was also in this 2011 thread https://bitcointalk.org/index.php?topic=20799.0

I looked at the thread and it is not what I suggest here

To OP, as someone who has stored some bitcoins in a cold wallet in a safety deposit box I don't appreciate this suggestion.

People seem to read only the title thread

They don't even care to read the opening post anymore, just the opening post, at least. Since right there I made it perfectly clear that I don't just suggest that all bitcoins sitting idly for a predetermined period of time should be blindly repatriated. This is only one option, though now I tend toward the two other options which I later added to the opening post as well

Well you should stress that this would be optional. I did read that part, but since it wasn't given emphasis and clearly explained how it would work with the existing protocol you can't blame people for ignoring it.

Who has exchanged BTC F2F?
 
Happened to me once, it was weird experience. I mean, moment you handing out cash and praying that he will not cancel 0 conf transaction until 2 hours after transaction (current average waiting time).

Next time ask the seller to use localbitcoins' escrow service. The 0.5% fee is small and the release is instantaneous.

I've done it in public places with strangers for transactions worth up to around $5K. I personally wouldn't risk carrying any more cash than that.
167  Bitcoin / Bitcoin Discussion / Re: If satoshi had a premine on: December 11, 2016, 12:37:12 PM
Where is the address satoshi owns with the 1 million btc?

I dont think that there is an actual address, i think it is if you add up all the suspected satoshi addresses it comes to a million.

Oh. Do we know of any big addresses supposedly belonging to him?

The first few versions of the Bitcoin core client had a built in CPU-miner. Most of the early coins that were mined by Satoshi and others were mined using Bitcoin core. The characteristic was that every 50BTC block was mined to a different address (in the same wallet), so there are no big addresses for these early unmoved coins. You just have a bunch of different addresses each holding 50BTC worth of virgin coins.

If "get out ASAP" means having to find another unsuspecting sucker to buy your shares/hashpower, then I would consider that unethical and draw the line there. However I'd have no problems selling them back to the company.
169  Bitcoin / Bitcoin Discussion / Re: What to do with lost bitcoins on: December 09, 2016, 11:50:26 PM
I don't think this scheme would be fair to people who use Casascius coins or even paper wallets. These physical forms of BTC can be passed around without leaving a mark on the blockchain. It would appear that the coins are "lost" but in reality they could be changing hands (without even incurring a transaction fee!)

In fact, if you are really concerned about lost bitcoins I'd prefer that the protocol be changed to remove the 21M cap and allow a small trickle of bitcoins to be mined indefinitely to make up for lost coins. This would be much more palatable than confiscating coins that haven't moved in a while.
170  Bitcoin / Bitcoin Discussion / Re: Anyone know the Bitcoin blockchain growth rate? on: December 08, 2016, 07:05:41 AM
On average a new block is created every 10 minutes.

Right now there is a limit of 1 MB per block.

So, if the limit isn't changed, then the growth rate is limited at:
  • 1 MB every 10 minutes (on average)
  • 6 MB every hour (on average)
  • Approximately 144 MB per day
  • Just a bit over 1 GB per week
  • A bit less than 4.4 GB per month
  • A bit less than 52.6 GB per year

It will generally be a bit less than the limit since not every block is always filled 100%.

If the block size limit is increased in the future, then the blockchain will grow faster, but making such a change will require an overwhelming majority of nodes, miners, and pools to all agree on the new rule.  It is impossible to predict what limit might be agreed to, and therefore impossible to guess what the maximum growth rate would be under new rules.

It is staggering to think what the impact of a 2 MB per block or even a 8 MB per block will be on the bandwidth and diskspace requirements to run a node. I agree, not all blocks will be full at all times, but what would happen, if it does. A lot of people in my country, have limitations on their internet bandwidht < Capped at 60 GB to 100 GB per month > A 8 MB per block, running at full
capacity will burn through that bandwidht in no time
, so this will effectively only allow people with Uncapped internet to host a node. < Weakening decentralization >

Off-chain solutions makes so much sense, when you look at these scenarios.

8*4.4 < 60

While the number is 35.2 GB that only counts for confirmed blocks. You would still burn through multiple times that just for the download part of your internet usage because of relaying of unconfirmed transactions.
171  Bitcoin / Bitcoin Discussion / Re: Can operating a Bitcoin node make you a target? on: December 05, 2016, 11:45:49 AM
alot of people think "use proxies". but that only protects the end user from knowing the source user..
ISP's will still know because they are packet sniffing the source user not the destination



Well you could use a reverse-proxy on a low-cost VPS (with sufficient bandwidth but not enough memory and disk) running VPN or SSH services and run the actual full node at home. Your local IPS will only see the encrypted VPN/SSH traffic between your home and the VPS, while the external world would only see the public IP address of the VPS, which could be in another country. I once ran two nodes at home and used this technique, not because I was trying to hide but because I needed a second public IP address for the second node.

If your VPS is located in a different jurisdiction, and if you can pay for the service with bitcoins without furnishing your actual name/aaddress, it would provide some level of isolation from local authorities vs. running a regular full-node at home.
172  Bitcoin / Bitcoin Discussion / Re: How do Bitcoins really circulate in a country? on: December 04, 2016, 11:46:55 AM
Also, many merchants accept it but don't actually care about its future, the cash it immediately and dump it on the market, those imposters can be recognized by their links to coinbase or xapo.

Well merchants dumping coins on coinbase or xapo is part of the flow or circulation. While this lowers the price it makes coins available for other people to buy from these exchanges. You can't really expect businesses, whose core competency is not virtual currency speculation, to hold their operating capital in an asset that fluctuates wildly. That is taking on added risk. In the extreme case, the fact that they could profit greatly if Bitcoin goes up does not negate the fact that they could also get wiped out if Bitcoin goes down. I wouldn't call these businesses imposters.
173  Bitcoin / Bitcoin Discussion / Re: Wikipedia Donation Campaign and still no Bitcoin on: December 02, 2016, 07:46:11 AM
Nobody updated to say they do now accept Bitcoin donations, heres your notice.    

https://wikimediafoundation.org/wiki/Ways_to_Give#bitcoin

Probably has a good secondary effect to represent bitcoin in a positive light if the wider internet can contribute to wikipedia.   If you prefer to find the donation page yourself, its top left on the front page.  Click that then way below there is tiny text saying "Other ways to pay"
Bitcoin is then an option along many other options

Using the links to donate requests personal information including name, email and postal address.  It should be stressed that donations in this way aren't pseudonymous unless you supply false details and use a discardable email address.  I suppose they must have some sort of legal or tax requirement that prevents them from simply listing their donation address directly.

You are free to use a fake name and address if you so choose to do so. They use that information to email you a receipt that you can use to file your tax deductions.
174  Bitcoin / Bitcoin Discussion / Re: How safe is to storage private keys in the cloud? on: December 02, 2016, 02:27:40 AM
If they are zip/encrypted offline,  placed in an encrypted veracrypt container (offline) and stored in a zero knowledge cloud risk is very negligible.  I just like to have options.

That will work. Just don't lose or forget your decryption keys. I store some BTC in an encrypted wallet within an encrypted zip file attached to a gmail draft message  Grin. It is ready to use anytime from anywhere in the world (except maybe in China and a few other countries where gmail doesn't work).
175  Economy / Speculation / Re: IRS sniffing around Coinbase on: December 01, 2016, 11:08:54 AM
Think about how fucked up this is. You buy something with cash or debit/credit card you don't report it, but you need to report every purchase using bitcoin? this is a serious attack against crypto, make no mistake.

They think bitcoin is an asset, like shares, gold or property. So of course you have to report capital gains. If you bought shares with your debit card and then made a profit on selling it, you would have to report that too.

I don't see a problem here either. The absolute same rules apply to bitcoin as an asset.

The problem is a matter of practicality. It every transaction in your wallet needs to end up on IRS Schedule D then many people in the US would simply not use bitcoins. Furthermore, you can no longer file 1040 EZ even if you were making minimum wage but you happened to have bought/sold a small amount of bitcoins.
176  Bitcoin / Bitcoin Discussion / Re: Scaling Bitcoin. Is consensus achievable? on: November 27, 2016, 10:23:28 AM
rationally LN should regularly close channels.
Could you please elaborate. Why LN needs to frequently close channels?

I would imagine it would be to periodically force an audit the value of the coins in the channel by closing out the books, thus making sure no extra LN coins have been created out of thin air. There should be better ways to do this, though.



177  Bitcoin / Project Development / Re: Agile software development and BTC on: November 18, 2016, 10:57:40 AM
We are using SCRUM to develop modern software projects in the company where I work. These software projects are like financial platforms that you can see around the forum, but we are doing it for fiat purposes. Does agile software development work in crypto projects too? What else could you use to develop BTC projects successfully?

Why not? The bigger problem with scrum is that it does not really work well when the team is remote, distributed and working across various time zones. This is even worse if the project is open source and developers are contributing their own time outside their regular work schedule. When would you run your daily scrum meetings?

I know this is an old thread, but i just started looking into this right now.
There is also this (master's degree dissertation) project:
Koshy, Diana. An Analysis of Anonymity in Bitcoin Using P2P Network Traffic. Diss. The Pennsylvania State University, 2013
http://fc14.ifca.ai/papers/fc14_submission_71.pdf

Does anyone know of similar projects/papers?

Blockchian != Bitcoin

There are so many misleading articles that confuse blockchain use by various companies/governments with Bitcoin use. I currently work at a large financial technology company that is incorporating blockchain technology into the trade settlement and clearing process. This work has absolutely nothing to do with Bitcoin or even cryptocurrency. The advantage of the blockchain here is that the multiple parties and counterparties involved in the process can exchange the trade messages with each other quickly, securely and with integrity.
