do you offer loan in ETH?
Nope. I don't really use altcoins.

Hello I was wondering if there is way of pinging a blockchain network or does it use a network protocol so I can see the networks IP or domain. I was just thinking how come all the mining machines are connected somehow. so what is the backbone of the mining machines and how do they see each other and somehow connected. They must have a some kind of connection and is it static kind of address? can someone explain it to me or give me some sources where I read the details about it?
No. While the network is somehow interconnected with each other, they aren't connected to each other directly. In Bitcoin, there are nodes and they form the backbone of the network since they are responsible for relaying transactions and blocks. Since the nodes are connected to each other, they form a web and the blockchain is within the web of connections. When a block is mined, it gets relayed to a peer and so on, till everyone on the network sees it. Mining machines aren't directly connected to the network, most of the time. In fact, most of them are connected to a pool which feeds them the information.

Yeah, no worries. I don't lend to people with negative trust. Loan amount request: 0.01btc Reason: mining costs Collateral: No Collateral Term Length: within 3 days Interest: 0.0015btc Address: 1AmsvsDVeu6uKWtDB7fqkh1du1a9AcW3k4 Amount to be Repaid: 0.0115btc
Why are you still trying to request a loan that I won't ever give, especially when I've deleted your request 3 times.

Bumpty bump. I'm back.
Welcome back ranochigo, happy to see you here and back on track. Thanks! Bump!

Hah I'm finally better than Sir Thermos in a category. To be honest, I didn't think I would've invested in that many coins but thanks anyways.
I've been waiting for this the whole day. Thanks for the great laugh.

When a block is mined, a coinbase transaction generating the block reward and transaction fees is generated. The miner is responsible for generating the transaction which can be constructed with various outputs, just as with a normal transactions.
You've likely seen the miner sending the block subsidy to various addresses.

Bitcoin isn't really suited for day to day transactions while people are pushing for mass adoption. What most people think is that its merely a bubble and it could crash at any moment.
Their misconception of Bitcoin is that its used primarily for illegal purposes. The same could be said with fiat with the amount of drugs transacted using cash.

Your crypto should be decentralised. With most coin, it is impossible for the client to see who or which IP has mined the coins. The client can only see who has relayed the block to them and sometimes, it is assumed that they were the ones who has mined the coin which is inaccurate.
With most mining pool, their coinbase transaction contains identifying information about them and block explorers interpret this to link the blocks to them. However, anyone can see the coinbase and potentially just use their coinbase data to bypass any restrictions.

As the supply decreases, the transaction fee would increase to compensate for that. It does not mean that the transaction fee per size would increase given the possible optimizations to the protocol. It would most likely hit an equilibrium and most miners would still be mining on it with their ROI'd ASICs.
Its also very possible that the decrease in supply would result in the upward pressure on the price and thus the price would likely be hovering at even higher prices. Obviously this is hypothetical and it would largely depend on the attractiveness of Bitcoin to the general public.

How about using Tails? Wouldn't the transactions made through Bitcoin Core be relayed through Tor by default without needing to do anything?
Yes. But the setup process could be more complicated. Tails is made to be a live CD and it doesn't come with Bitcoin Core by default, but it does come with Electrum. Why don't you try setting it up on your normal computer instead of trying to install another OS completely? Personally, I wouldn't really use Tor for everything. There is a known list of exit nodes and some sites tend to block those IPs completely. I don't think there is any way for the user to allow the traffic to bypass Tor. It's a good way to preserve anonymity however.

Generally, to be 100% safe, I wouldn't recommend anyone using cloud storage at all; be it the chainstate or the block files. It would probably be somewhat fine if you don't expose your wallet.dat to any cloud storage. Are you using Core for personal use? If so, you might want to consider pruning the blockchain by creating bitcoin.conf in the data directory and inserting this: . You can shift the blockchain back into the HDD once you've done this.

This is new to me. If I understand this concept correctly, it should eliminate the need to trust an abstract website and its security setup. Rather, I could trust a real person that I know, or even better several individuals to verify that I have, e.g., an authentic electrum wallet. Has this concept been accepted to date? I mean, do you people use it when installing sensitive software from the internet?
You're correct. Websites should not be trusted and users can't trust anything on the internet when they are validating things. It's simply unrealistic to go around passing your PGP keys but meeting someone face to face to authenticate their PGP keys is certainly the most secure method, you can't go wrong. I haven't really heard about bitkey before. Is there a widespread use of it? Again I ask this question because of trust. For electrum, I can be pretty sure that (due to its widespread use) its source code has been thoroughly vetted before. So I just have to trust the signature. Sure, as you indicated, there's the source code of bitkey, but how many people have gone through the code to check it?
On the other hand, bitkey seems to be similar to tails, which I have been considering to use as a form of more secure linux. How different bitkey is with respect to tails?
I would recommend for you to just use a more established distribution to use Electrum with. OS like raspbian and ubuntu has been vetted hundreds of times and it is unlikely that they are intentionally including any malicious code. Even if they are, the airgapped setup would pretty much eliminate most of the threats. AFAIK, Bitkey doesn't route data through Tor.

I understand the sequence in a standard core download. You install the core software, and then either you give it an empty directory for the blockchain, or you give it a preloaded directory for it to check and synchronise. Once it has done that, does it create the wallet, or is that done in the initial core installation?
If the directory does not contain anything named wallet.dat, the client will automatically create the wallet file at start up. If you have downloaded 99% of the blockchain, would it not be possible to copy the created directory onto an external SSD ( or an SD card), and take it to another computer to install a new version of core, and give it the copied blockchain to see how it handles it?
If it has downloaded 99%, and then is failing each time, then the fault must lie in whatever operations core does when it completes the download. Were it to be a faulty block, then the additions to the blockchain between downloads would reduce the percentage.
It's possible and thats essentially what the OP is doing now. If anything, I would suspect that the SSD has some issues with it and its not with the computer or the synchronization itself. At what stage do you give it an Armory wallet? Can you perform a standard installation, and add the armory wallet afterwards?
Yes. Armory just needs the data from Bitcoin Core to run. As long as you can point armory to the synchronized blockchain, it would take a few minutes to read the blockchain and create its own database.

Depends on what you define as a wallet. Its certainly possible for online wallets to include as many cryptos as they want. The users don't have to have much resources to use them. For desktop wallets, full nodes could be quite a lot harder, especially with the fact that some blockchains could take up quite a significant space.
Exodus is a wallet that does this. I wouldn't consider it as secure since it is a server validation wallet.

Thanks much! So, ./bitcoind (now ./bitcoin-cli ?) does not provide simple one function to make Address?
It does. The command is getnewaddress.

Majority of the community can't control the price change since its influenced by the demand and the supply of the market. The price of Bitcoin has been unsustainable for a long time. If anything, the rise in the price was indicative of people buying with hopes of being rich. It wouldn't have risen so fast if the adoption were to increase.

With Bitcoin Core, the DNS seeds aren't IP addresses but they are actual domains. With the actual domains, you can update the address for which they are pointed to for the client to get the information from.
Changing the source with every IP change is very tedious for the users.

Yes it is. But who will pay if someone robbed their coin.? Would there be any formal agreement between clients, owners etc.? Unlike banks, there is. And also they pay all their clients if there will be bankrupcy or any worse case. Speaking in the context of Bitcoin, no one would compensate you if you were to get robbed of your cash on the streets either. Just like Bitcoin, you control your own cash and not your banks. With the agreement, I'm certain some sort of contract could be made using other blockchain technology and it could uphold in the code of law. Bitcoin is primarily for day to day transactions and not for things that would require trust beyond that transaction.

I just don't like the idea of not using something when broadcasting a transaction. You are making a transaction through your real IP, this doesn't seem too safe. But then again Tor doesn't seem too safe too from what im reading, I also don't want to host anything that could incriminate me somehow, I've read people running Tor nodes that never did anything wrong, ended up raided somehow.. no thanks. Could this happen if you need to host your own hidden service too?
Tor works by using relay nodes and exit nodes. Exit nodes are the ones responsible for getting your data relayed to the clear web. Relay nodes just bounce the data within the network and they are pretty safe since they aren't responsible for relaying information to the clearweb. Isn't Electrum safer than using a full node with your real IP? I mean the transaction in Electrum goes through some server, and not your IP directly.. it's a similar model to VPN where you would need to trust that whoever running the SPV server is not selling logs.
Im not doing anything ilegal btw, I just don't like the idea of people having your real IP when you are transacting.
Bitcoin Core is by far the best for privacy. The way Electrum client works is that they send your addresses to an Electrum server that is run by the community. This could expose your privacy quite significantly. Bitcoin Core doesn't do this since they store the whole blockchain. Peers would not know who sent the transaction when using Bitcoin Core. The peers would only know that you've relayed a transaction but they wouldn't know who sent the transaction.
