Bitcoin / Project Development / Re: [All welcome] BITZARD will do PROGRAMMING for You [No requirements]

on: February 20, 2017, 03:46:47 PM

I just need your response, not finish the project. How much for a block explorer? Can a block explorer be created in javascript when the explorer only read blockchain files using HTTP + Cross Origin Resource Sharing . Do you think this is possible? Or very difficult? If so why? I think it would work OK for small blockchain, but when the blockchain becomes large, it's slow down. What do you think?

Quote from: inca on February 17, 2017, 05:38:49 PM Quote from: 2c0de on February 17, 2017, 03:36:59 PM Try Nakamoto Hash Tube algorithm to sign blocks. If the full node signs two distinct blocks, the key strength collapses. This ensues that no fake histories are created. You mean this?: https://www.docdroid.net/mR3fUNS/paper.pdf.html Yes. A super long hash tube with a private key on one end and a public key on the other end can be generated. Then you sign bits using successive tube levels. Every client then knows that only signed blocks are valid. Quantum proof. Full node cannot change history or create fake histories.

Alternate cryptocurrencies / Altcoin Discussion / Golang coin networking needed

on: December 11, 2016, 06:43:27 PM

Please experts, I'm dev, I have coin developed in golang for weeks, wallet+consensus+database all work ok Now I need networking & UPNP (to bypass nat) , block delivery, witness delivery, sending transactions NEEDED. Which golang coin has the best networking I looked at Skycoin and Ethereum do you know any other. Thank you EDIT: another option is just fake it and put blocks on a web server, many early coins do this. Is this a good idea?

Project description -Tape printing of scannable TO codes with balances Skills required -JS, HTML Equipment -Android cell phone Use case 1 - create a tape 1. The user pastes a long list of Bitcoin / Litecoin / Dogecoin addresses (optionally with space separated "balances") into a text area 2. User selects a detailed format, online balance checking or other options. 3. The user hits Generate button. 4. If the balances should be checked, a specific URL is used to poll the balances. 5. Nothing but a long tape of bar codes appears on a HTML site. 6. User is able to export the tape to a PDF file, as well as print the tape from the browser. 7. Upon printing, every individual bar code on the paper tape can be effortlessly scanned using the provided app. See U.C. 3. Use case 2 - wrong addresses present 4a Invalid addresses on the tape are displayed upside down, with a special symbol, with negative balance, or the whole tape is not shown. 5. User is notified how many invalid addresses are present. 6. User is able to clear invalid addresses, as well as ignore the warning. 7. Continue the use case 1 step 3. Use case 3 - scan tape bar codes 1. User scans individual code on a physical tape / HTML / PDF file using a phone app. 2. The code is scanned correctly and a specific activity is launched on the phone. Extra The width of the tape is 80mm, 57mm or custom. The length of the tape page is unlimited or N codes per page or fixed height in mm. [URL 1] http://www.2c0.de [URL 2] https://movedon2otherthings.github.io/

Bitcoin / Development & Technical Discussion / Re: An idea to significantly improve transaction throughput in bitcoin

on: September 06, 2016, 04:47:40 PM

Problem #1: Why did the confirmation (green light) disappear? Problem #2: Why do the real miners suddenly collect more fees? Where does the money originate from?

Satoshi walks into a bar and asks for a beer. Dorian walks into a Walmart and asks for a TV. The barman asks for 0.654 BTC The cashier asks for a 7.46 BTC. Satoshi activates the magic last miner key, a green light appears at the bar, Satoshi walks out with a beer. Dorian activates the magic last miner key, a green light appears at the cashier's screen, Dorian walks out with a TV.

on: August 17, 2016, 02:49:53 PM

delete whole blockchain install fresh bitcoin qt let it synchronize for a few days when it's fully synchronized OK, - shutdown - backup your blocks/ , blocks/index/ , chainstate/ folders when you get corrupt or need start bitcoin fast, just copy blocks index and chainstate back, and voila!!

They can read blocks, because blocks are append-only. Only one program can write new blocks. But they cannot share chainstate and the other.
