Thanks for the mentioning it up. Truly speaking, I designed the signatures last year for both btc and eth and created a topic for it. But they were not created keeping the signature standards of the forum. They had more characters and cannot be added to the signature space of the member. Later this year I redesigned them according to forum standards and published them.Most of the members just had a text in their signature mentioning btc, hence I thought of creating one. I even thought of what it would be like, if satoshi held a signature campaign for promoting btc  I still have not understood why the author used quote inside his post ^^
Sorry, for my lack of carefulness.
It was because the signatures weren't a original post, they were referenced to my earlier topic created last year. But those old codes were really bad and I redesigned the new codes this year. I am also thinking of creating signatures for other coins when time permits. |

i don't know why people think C++ as soon as it comes to understanding bitcoin. you really don't have to know C++, any other programming language works. obviously because there are a lot of libraries that are "translation" of bitcoin core which you can read in your own "language" like python, but also if you know any programming language you are familiar with programming and you would still understand C++ too to some extent.
Programming on the whole are inter-dependent and inter-connected to each other. Understanding one is equivalent to getting a grasp on almost all the programming languages and it's flows. Also, programming alone won't help one in learning about bitcoin or any other cryptocurrency. They need to have knowledge in cryptography to understand how algorithm functions, how keys are created, how the hashing target is achieved etc. If neither one of them are known, we should better start learning everything from the beginning. on top of all that bitcoin has a very good documentation in form of a wiki (bitcoin.it/wiki) developers reference ( https://bitcoin.org/en/developer-reference) and the BIPs which means you sometimes don't even have to look at code to understand how certain areas of bitcoin work. True. As you have said we are not in the early stages of bitcoin to read the code and understand everything. Almost everything has been detailed in the developer docs and there are many books/references for one to have a better understanding on the network without reading the code. Summing it up, If one needs to become a bitcoin developer, he needs to read the code else documentation is enough. |

im sorry for my rude comment earlier. but It dont have any gui. and yes we have tried changing network based on your suggestion, but it dont work.
No issues dude. I do verify each and every time before I post anything in tech board. Most of my posts has somehow contributed to the topic or helped OP in solving his issue, helped them in understanding simple commands on smart contracts etc. Also I don't post what comes to my mind, I do verify with older posts and issues in github before posting. Negative confirmations has been probably a common issue during server sync. Check out earlier issues raised in git and also if it doesn't solve your issue you better ought to delete the block headers. That might be one of the possible ways. If that doesn't solve either, you better need to wait for an electrum dev to answer your issue in github. Check this out buddy  Deleting the block_headers in the .electrum directory to download it again does correct the unverified issue
P.S Is this issue raised by you? |

|

are you a troll?
What makes you say so? At first I thought your issue was on ElectrumX and I would have mistyped them considering it as a software. But now you are saying so, you are using software and not server. If your issue is negative confirmations and it is in electrum software/merchant wallet then what I have said is right. So you are mentioning about this right? : http://docs.electrum.org/en/latest/merchant.html |

Seems like the transaction has been confirmed while checking through the block explorer. Negative confirmations is a well known bug present in the electrum software. Resyncing/re-connecting to a newer server will probably solve your issue I guess. I use electrum, im not using my own nodes. why it not sync?
Electrum is a light wallet and it doesn't download the whole blockchain. Rather your wallet syncs to a server running a full node to broadcast transactions and update your balances. Servers can go down at times. To restart/resync electrum do I need to reboot the server? Electrum daemon was running all the time. Shouldn't it sync?
Press the green button present on the bottom right of your client interface to resync with new server. When you click that, Press the server tab and select a new server from the list. If that doesn't solve your issue and if it still persists you better need to delete the block headers.  |

Good write up. It would be interesting to see which block gets the timestamp of 2019-01-03 18:15:05. Ten years is no longer way but the development, changes, acceptance it has undergone is literally sky high. Satoshi and the fellow helpers like Hal, sirius has undoubtedly made many people millionaires and billionaires, has challenged government organizations, brought up the future of money and what not. If satoshi alone was promoting this right back in the early days of the network, it would not have reached such heights. Apart from theymos, most of us came here only after what came to be known as cryptocurrency. Satoshi was not only a good coder, he was probably a good economist too who thought upon various economic aspects of making bitcoin future of money. Usually when we do
Of course you understand that the intention is not to belittle anything. Even then, if you feel this (as a programmer yourself probably), it'd be helpful if you give your own perspective on the difficulty level of the code. It'd be good knowledge for learners like myself.
I am not a C++ coder, but based on the knowledge gained from my university it is easier to understand the code if you have read some basic level of programming and know how cryptography works. The flow could be easier to you only if you know where the cryptography gets applied in the code. Unless it could be a difficult time for beginners and newbies reading the code. For people like us, we can understand better by compiling the code. You can also follow the codebase present in git and read the issues, PR which are raised by devs for easy understanding of how the flow works. If people are not part of any signature campaigns, here are some signatures designed by me for celebrating the 10th Birthday.

1.Finding a block means guessing a number.
Yes, true. In order for a miner to find a block he needs to do a trial and error method by inputting various nounce values and the resulting hash should be less than the current target. If the hash is higher than the target, he need to change the nounce and try again until he reaches the desired hash. Once he has found the hash he found the block. 2.That number involves showing that the transaction involves the right keys and then ..putting it through some meth equation? Is that right?
No. The transactions are struck in the mempool. These transactions are already validated by a bitcoin node and added to the pool of unconfirmed transactions. Once the miner finds a block, he picks up these transactions from the mempool (probably the tx with fees) and adds them to the block he is gonna mine. Along with a list of transactions included in the block, he adds a block header he has computed and a coinbase transaction which is the first transaction of any block that pays the miner. What I wonder is ...is the miner constantly guessing numbers based on whatever transaction he intends to add to his block?
And so the transaction variable of the guessing is constantly changing?
I guess you have misread everything about how mining works and how transactions are validated! Miners constantly try to find a block by using up different nounce values. There is nothing to do with transactions and blocks. So the miner is moment by moment is solving for a different pool of transactions?
Whoa, NO! Please read Mining and Consensus : Mastering Bitcoin to get a complete insight of how Mining works. EDIT : Oops, achow already answered... Typing in mobile is one of the hardest jobs  |

Merry Christmas to all the bitcoiners and crypto enthusiasts present here!! It's been exactly 2 years since I came to know about crypto. On the eve of Christmas, 2016 while browsing through economics news I came to know something known as bitcoin. Being a dev myself, I never thought of or came across such an idea that one could use cryptography to such extremes for creating digital money. I believe Santa has delivered me the right gift(knowing of bitcoin) 2 yrs back. Hope St. Nicholas has delivered the gifts to the children present in your home... Once again Happy Holidays and Merry Christmas |

The majority of the world population hasn't got to know of btc instead, or doesn't understand the basis of tech which powers the blockchain and cryptocurrency technology. We do agree the fact, that it is difficult for a non tech person to understand and use btc in real world, but btc would rise up as similar to the internet craze. Back in 90s and 2000, most of the world population were unaware of the internet and many of the investors (Inc Buffet) lost the opportunity to invest in internet based startups such as Amazon, Google etc. When more regulations come in and btc becomes a global currency, uneducated and non tech people who yell at btc as a SCAM will realize they have lost the chance.
We have been commonly seeing through market and price drops/rises right back from 2011 and the year after block halving. If we check through the decade long graph of the market, you might figure out there has been a meteoric rise in prices all over the market the year after block halving. Such situation has occurred now and bears continue to dominate until 2019.

Is your electrum version up-to date? If not try to update them, and then try logging into wallet.
Post the tx hash, error info and also a screenshot of transaction history of these 2 txs. Either you might have sent them to Local wallet, or it might be version issues of electrum or connection to the electrum servers.
You can only spend UTXO of a transaction as an input for another transaction. If there isn't any utxo left to be spent as an input, you will receive missing inputs error.

bitcoin mining is a process adding blockchain transaction or other as bitcoin transaction like bitcoin ledger ,wallet process and other utilities transaction
Not exactly true. Mining is the process of adding unconfirmed transactions to the blocks and then finding/solving the hash of the block to match with the current target. Miners/ Peers who are looking to solve the block add the transactions(hanging around in the mempool) to the empty blocks, and then solve the block hash to find a suitable hash which would be lower than or equal to the current target. The peer who does this, broadcasts them to the network and other nodes/peers accept them. By this way of dedicating their electricity to find the suitable hash, these miners are awarded with bitcoins by the network. These bounty gets halved every 2016 blocks and when this reward diminishes, miners solely depend on the tx fees of each transaction. so without mining how can we process our transaction without mining.how can i work the blockchain without mining. please correct if i wrong. Yes, it is possible to send bitcoin or do a transaction from your wallet, but it won't be confirmed by anyone i.e the other person won't be able to spend what you have sent to him. While considering LN, miners are not involved directly with the transactions, but they are required for opening and closing of a channel. Opening of a channel occurs on-chain which requires a miner and thereafter all the LN tx occurs off-chain. P.S I am not really familiar/have never read anything about Multichain, but I have read somewhere that Credits and IOTA Blockchain platforms don't require miners actually. (Not really sure) |

What's this about intrinsic value? As I understand it, Bitcoin has no intrinsic value. It's only worth what the next person is willing to pay.
What makes Gold and other precious metals to be more valuable than other metals? Over times, people have accepted that to be store of value and buy them so that they would be worth something higher than what they have bought. Gold price is not based on what other people spend for it! People spend money to mine them and mining is not done free of cost! Moreover, bitcoin is not something similar to a stock of a company to be worth enough or to be based on others traders buy orders! They are created for the purpose of serving as a digital money and in the future we will shift to them. Bitcoin is similar to gold. Miners spend money in the form of electricity to mine btc which costs around $4500/btc at the current difficulty even in third world countries where electricity is literally cheaper. With ETF and newer regulations coming out in Q1 of 2019 it is expected to rise in price sooner. But ATM miners are at loss and whale movements prove to be a bad sign for the upcoming days in the market. Once btc is considered to be global payment system and new regulations rise up, we will see new highs. Till then bear continues to dominate the market. Many people believed in DotCom Bubble but they got adapted as days passed by, such thing will happen with the digital money. |

(1) How is it possible to send ERC20 Tokens without gas? Gas is something like a fuel which must be specified for each and every transaction to take place in the ethereum blockchain. Does your vehicle run without fuel? It is not really possible to send a transaction without gas. What you can set is the price of each gas unit! This may range from 0.1 gwei to how much ever you need. There are decentralized exchanges which use tokens as tx fee instead of ethereum. For such tx to occur you don't need to have Eth in your wallet. The exchanges withdraw the fee from the tokens you are trying to transfer. 1- the gas price is not zero (0.000000), but something so low that etherscan consider as zero, such as 0.00000001 eth . Yes that's true, you can specify the gas price as low as 1-10 wei which might be confirmed by the miner after few hours. 1-10 wei is so small that would be equivalent to $0.0001 which etherscan would have rounded off to $0. With eth price being as low as $100 the price of the tx would be considered negligible if we specify it in wei. |
