Litecoin was not the first altcoin. It actually uses ideas for altcoins that precede it but had died before it was created. This is mentioned in its announcement thread on bitcointalk.. The very first altcoin was actually Namecoin, announced in April 2011. Namecoin was actively used and mined, and can still be used today.

Decred is limited in what you can amend with on-chain governance. With Tezos you can amend any part of the protocol, including the governance mechanism itself.

To find string with in the files (including binary files), issue the command: grep -rnw '/home/user/' -e 'bitcoin' It will return every single entry for the word bitcoin in your code. But I do not think that's the best way to get what you have in mind, what about "if" you have a CONST or a variable in the code called const BITCOIN or bitcoin ? Your ...

When dealing with a centralised exchange, there are only two points of interaction with the blockchain: Deposits and Withdrawals. In order to process deposits you will need to monitor transactions to certain addresses. A withdrawal can be processed offline with only the signed transaction being broadcast to the network. For safety reasons it is best that ...

Pretty much any mining operation short of buying hardware (ASICs, GPUs) is a scam. IQ Mining appears to be a ponzi scheme of some form based on a quick Google.

Different networks are completely independent, and while it is technically possible to put together a single node software that is able to connect and process all of them, it makes little sense for someone to invest that amount of time and money in it when you can simply run each network independently (even on the same machine).

I've asked myself similar questions which lead to learning more about mnemonics with Bitcoin, and like many other (not all) cryptocurrencies, which use BIP39 which is a specification based on a unique wordlist of 2048 words (zero-indexed from 0-2047) available in various languages (although I should note that you cannot translate words across supported ...

Is it possible to convert back and forth between say, for instance, a 24-word phrase to a 12-word phrase, and what tools can I use to make the conversion? No, that is not possible. The mnemonic words represent an entropy, for example the 24 word mnemonic phrase represents 256 bits of entropy while a 12 word mnemonic represents 128 bits of entropy. These ...

As described by Andrew Chow, Namecoin was the first altcoin created as such. It was announced on 2011-04-18. However, according to the question Testnet version history the testnet1 was reset after its coins started to get traded for value. Testnet 2 was kicked off on 2011-02-03, which would allow a case to be made for Testnet 1 to have been the first ...

If you were using a fork of Bitcoin Core, your small scale network would not work. Assuming you did the basic chain parameter modification or just firewall yourself from the rest of the Bitcoin network, there are two major things that are missing: peer discover, and mining. Bitcoin Core by default uses a process called DNS Seeding in order to discover seed ...

invalidateblock "blockhash" Permanently marks a block as invalid, as if it violated a consensus rule. Arguments: "blockhash" (string, required) the hash of the block to mark as invalid Don't delete the blocks manually, you'll harm the database.

This question is somewhat like asking, "how can I steal money from myself?" Since you are the only person participating in the consensus of your altcoin, you control 100% of the hashpower. A 51% attack creates an alternative ledger, breaking consensus on which coins have been transferred, allowing the attacker to create a double spend. First mine two ...

I want to make such ones for other coins, too. If I could make altcoin vanity addresses of the same key pair preserving the “TEST,” that would save some computational resources for me. This would work for other coins with the exact same address alphabet as Bitcoin (which is most bitcoin clones), and the exact same version byte. Addresses in bitcoin are ...

No l, floating point operation are pointless, regardless of how fast they are or what precision they have. Also, BTC is mined using ASICs since 5 years ago or so, using a GPU is a waste of time and money.

This is because you didn't mine the block, i.e. you didn't search for a nonce that results in a block hash less than powLimit (the initial difficulty target) defined in src/chainparams.cpp consensus.powLimit("00000000ffffffffffffffffffffffffffffffffffffffffffffffffffffffff"), for mainnet. To do this: Serialize the block header. Concatenate (in this order, ...

Think of this as a 2 part thing: First is storage of said currencies. The ones you have, and the ones you want to trade for. This will likely result in owning multiple wallets. The other is trading of the crypto. Exodus, as Willtech stated has been increasing support. They incorporate wallet and trade using APIs with Shapeshift (iirc). MyEtherWallet.com ...

there is no faster way to rename , but there are steps you have to rename the bitcoin source code.. for ex let your altcoin's name be : andracoin First : inside the src folder use this command : find ./ -type f -readable -writable -exec sed -i 's/bitcoin/andracoin/g' {} \; then: find ./ -type f -readable -writable -exec sed -i 's/Bitcoin/Andracoin/g' ...

Generally if everything goes fine it's safe. Though if something goes wrong then it's much harder to investigate and act as your control over exchanges' wallets is very limited. My personal approach is -- understand the risks and proceed :)

There isn't really a service that can do that as there isn't a purpose but you can, however, is mentioned already are mine or use a faucet or ask anyone you know who has extra that you can use and after you finished with it, return or give those testnet coins away to other developers that need it.
