1  Bitcoin / Development & Technical Discussion / Re: Helix Blockchain on: May 21, 2015, 07:06:09 PM
Sounds like a fun experiment for an altcoin... ;]

It works as a soft fork too.  Just define every fourth block as being in the same chain.  Transactions are only allowed to be in block N if the last 2 LSBs of the UTXO's digest match the block height.

This would split all current outputs 4 ways over the sub-chains.

Why 4?  What is the principle behind this number?  Why not 3?

You can almost imagine this as sort of developing a 6th sense... you'll be able to "feel" each others thoughts or emotions.  Not explicitly read each others' minds, but "feel" it.  How do you explain what it's like to see to a blind man?  Or what taste is like?  In the same manner we can share experiences with each other and develop this sense of what it's like to "feel" like someone else.

It could be addicting in the beginning - almost like social media and everybody being attached to their phones - we'd try to experience every feeling or emotion that others offer to share.  Instead of exploring ourselves and our own minds, we'd be consumed with the thought of others.

On the other hand, it could be a good thing.  We could share our thoughts so that we can better understand one another.  We'll be able to figure out what love feels like.  Or happiness.  Or anger.  We can work together and perhaps advance exponentially as a society.

This connected society will be viewed as a brain or separate entity itself.  Each of our minds is like a separate neuron firing in the brain of the world.
3  Bitcoin / Bitcoin Discussion / Re: Entropy, complexity in blockchain giving rise to megablocks, hyperchains. on: May 20, 2015, 07:05:57 PM
  We are developing a new technology; A way of doing things differently than they have ever been done before, with the Blockchain and Bitcoin. 

  It is obvious that as we progress further down the path that Bitcoin and it's blockchain concept allow, complexity will give rise to a sort of entropy of method because of the availability of many more disruptive technologies; Technologies such as hashes, cyphers, Homomorphic encryption, Magnet links, etc.
 
  This allows us to create Blocks within Blocks linking to Blocks of information on not just one but multiple Blockchains linked together or transactions linked together. Information simply being itself, linking and forming as it is most apparent.

  What am I talking about? Megablocks: Blockchains with separate information perogatives linked to other dynamically generated Blockchains, Hyperchains: Transactions linked across Blockchains, and Proxy Blockchains: Blockchains secured by other Blockchains, different than Mergemining, Ephemeral Blockchains: Blockchains created inside Blockchains.
  With this, new forms of Blockchains will arise linking their state, referencing each other in a secure decentralized manner, forming dynamic minichains, hashing of blockchains into blockchains for security, Magnet linking blockchain states, a multistructure web of Blockchains.

ChainDB does a lot of what you're talking about - other blockchains referenced inside of Bitcoin's blockchain.
4  Bitcoin / Bitcoin Discussion / Detailed Block Graphic/Chart on: May 20, 2015, 05:29:13 PM
Is there a detailed graphic that shows what all goes into a block (prev. hash, nonce, transactions, timestamp, etc...)?  Ideally, I'd like to visualize a completed example block. 

Is the final output in json format?  Where can I view ALL of the output for a block?
5  Bitcoin / Mining / Re: Mining with PHP (for educational purposes) on: May 15, 2015, 03:11:44 PM
Does anybody know of a project experiment for mining with PHP?  I know it's not efficient, nor will it make me any BTC, but I'm interested for educational purposes.

I would actually like to see the nonce increment, added transactions, and the resulting hash.  It'd be easier if you could control hash rate (i.e. 1 hash per second, etc...).

Does a project like this already exist?  Possible?

You mean something like this: https://github.com/codler/Bitcoin-phpMiner
What is the real reason you want it for?

Nevermind I don't wanna know....

I want to help my dad/family understand it.  I want to create a "live view" of the blockchain.  An animated view of the previous block with transactions, nonce, hashes, etc...  while showing the current block being mined (i.e. iterating nonce + transactions + prev hash).

Some people are visual, others can imagine what the code does in their mind.   I want to try to bring these two together... for educational purposes.  I know this will never mine a block, but I do want to show what's going on.

8  Bitcoin / Development & Technical Discussion / Re: [Theory] The optimal confirmation time on: May 12, 2015, 06:31:31 PM
I don't want to sound too harsh, but it doesn't seem like you know what hashing in Bitcoin does exactly.

https://en.bitcoin.it/wiki/Proof_of_work

I thinking in more abstract terms here than purely the computation of hashes; hashing power can be thought of like stake, in that the more hashing power you have, the more invested you are in the network and the more control over the consensus you have.



You see that is centralization, right?  The gov't has more control of the monetary network today, they control the "consensus" of inflation.
9  Bitcoin / Development & Technical Discussion / Re: [Theory] The optimal confirmation time on: May 12, 2015, 05:49:06 PM
Maybe I'm not stating my question correctly.

This is entirely a theoretical question, so imagine there are no blocks, but we still do have hashing power on the network (or stake, for a POS chain) in order to be able to reach some kind of consensus.

Under these broad assumptions, is the optimal confirmation time (fastest possible time to form a robust consensus) simply the time it takes for >50% of the hashing power/stake to agree on any given transaction, or is it more complicated than that?

I think you're confusing the term 'verification' with 'confirmation.'

Hashing power is used for finding the block by including transactions and iterating through a random number (nonce) in order to change the hash output to be less than a target value (0x000000000000blahblahblah).  We can then verify quickly that the proof-of-work is true (yay math!) so that other miners will accept this block and move onto the next block.

We can't "imagine there are no blocks" without there being a basis for "consensus".  From the 0 (genesis block) to the current block we believe all the information to be true because we can openly (and quickly) verify it - that's your consensus.

What I think you may be asking is... the time it takes one miner to find a block and broadcasts it to the network - the time it takes for all nodes to receive this broadcast and verify it so that they may move on to the next block, would the optimum time be for the target value to adjust to >50% of this broadcast/verify time?  

Let's say it takes 30 seconds for all miners to receive the broadcast and verify the proof-of-work.  Should we adjust the target value so that a block is found every >15 seconds?  Is this what you're asking?
10  Bitcoin / Development & Technical Discussion / Re: [Theory] The optimal confirmation time on: May 12, 2015, 03:32:07 PM
A ‘confirmation’ is when a transaction exists in a block.  Each subsequent block further confirms that transaction.  6 confirmations means that the transaction exists in a mined block and 5 other blocks were found thereafter.  Remember, each block references the previous which makes this chain stronger.  It’s mathematically sound to allow for

  • 0 confirmation purchases under $20,
  • 1 confirmation <$100,
  • 2 confirmations for a nice TV,
  • 3 confirmations for a vacation package,
  • 4 confirmations for a car,
  • 5 confirmations for a house, and
  • 6 confirmations for a fighter jet.  

A double spender would have to computationally create new blocks to create the longest chain – it would be more expensive to try to double spend this way.

A ‘confirmed transaction’ is one in which the ENTIRE network has signed off on by including it in a block.  0 confirmations just means the transaction has been broadcast and miners should include it while trying to find the next block.

12  Bitcoin / Project Development / Re: Case Wallet launches Pre-sale at Techcrunch Disrupt! on: May 05, 2015, 12:59:17 PM
How accurate are fingerprint scanners?  Ive never used one.

I'm thinking this device is for more day to day use and not for storing large amounts of bitcoin?  Not sure if I'd feel safe putting 20+ coins in one and putting it in my safety deposit box.  I'll give it some thought though.  Looks very cool.

I've never heard of this celery exchange their partnered with to buy and sell coins though.

Sorry if I missed it, but is there a way to recover your wallet if the fingerprint scanner isn't working?  That seems to be a weak point.
13  Bitcoin / Project Development / Re: Case Wallet launches Pre-sale at Techcrunch Disrupt! on: May 04, 2015, 07:55:06 PM
How is this offering different from Ledger Blue?

https://medium.com/@Ledger/ledger-introduces-a-secure-portable-and-developer-friendly-hardware-wallet-protected-by-stm-s-tech-13c25b113723

Is it similar?  What are the differentiators?

Please read first... " who is able to give me 6$ worth of BTC, i will send them back to the sender`s wallet in 24h" i asked for free money? lol
I am at sub way now and i just wanted to test the btc payment but anyway...for many people 6$ means a lot of money how i can see and i already taked my order with cash so i dont need btc anymore.

Please don't waste your time, no collateral = no loan for newbie



Haha apparently scammers can only use one address?

I don't agree with the way they went about raising funds, it was probably Charles Hoskinson's idea. I didn't purchase "ethers",  considered it more a donation than an investment.

Despite spending months of my life trying to figure out the legal and tax implications of it and even moving to Switzerland for three months, I was always against the ether sale and wanted to take VC money. It made a hell of a negotiating point for valuation, but introduced a terrible moral hazard of having no fiduciary responsibility behind the enormous sum raised. Also no formal due diligence process would be applied to the core team.

If there was to be a sale, then I wanted two organizations to form with a VC funded for profit building the initial protocol and then a sale at the time of launch to fund a foundation with a separate board managing it. This would create a clear separation of concerns and avoid conflicts of interest. Second, the risk to ether purchasers would be substantially less and would have eliminated the need and justification for a premine altogether. Obviously that didn't happen and the project decided to use the sale to fund some sort of bizarre swiss NPO funding a pesudo for profit in England two months after I left in early June.

Since then they've apparently spent or lost 14 of the 18 million raised and have missed two launch windows for a command line barebones version of the software. Second, they've experienced terrible mission creep with a mandate to re-invent the internet as opposed to simply giving the space a much better foundation to build cool blockchain centric applications and protocols. I'm honestly not sure what ethereum is anymore? Whisper, Swarm, Golem, Holons, Open Org, 4 new programming languages, DAOs???

In any event, don't blame people you've never met for things you know nothing about. Ethereum would be a very different project if I was still there. I'm not and they don't even have me listed as a founder nor did Mihai even mention me once in his history of the project. Thus I suppose I never played a meaningful role. 

A once insider, now an outsider looking in... what path do you see Ethereum ultimately taking?  They seem to have the attention of big players (IBM, Samsung) - it lends a certain credibility.  But from your response they don't seem to be what they are purporting.

18  Bitcoin / Bitcoin Discussion / Re: Remove Satoshi as Founding Member, Says Bitcoin Foundation Director on: April 30, 2015, 12:23:04 PM
This is equivalent of removing Jesus from Christianity.  Just because he didn't specifically found your church (foundation), doesn't mean he's not the SOURCE of your religion.

In Crypto We Trust

Im not sure what it is really, but I invested. How could one not with the amount of btc they raised!

IBM is very interested in it too...
20  Bitcoin / Bitcoin Discussion / Re: Bitcoin Internet of things? on: April 29, 2015, 07:14:35 PM
For me the "internet of things" is still a cool sounding buzzwork, but I don't see the benefits from having, say, microwave oven and a fridge that's connected to the internet. Isn that a bit over the top? this being connected to everything constantly is getting pathological imo.
I hear you. Although the model of the future may have the machines interacting more than us. For example that fridge could do your shopping as you run out of milk and eggs. The microwave could download and suggest a meal plan as it works with the fridge on ingredients. Low on gas? no worries after dropping you off at work your car heads to the gas station to spend some bitcoins. It has also bought a water pump today to replace the one it senses is going bad. All these sorts of things could run in the background of your life.

All that does is being prone to being hacked 24/7, since you'll have it all connected to the same wifi, and once a hacker gets into your fridge, he may jump in your computer. I dont know, not convinced by this shit myself as well.

Each device acts independently.  WiFi facilitates a transaction.  A hacker can't do anything unless they control a private key.
