Namecoin source code
Disclaimer — This article is an excerpt from the book Mastering Blockchain, Third Edition by Imran Bashir, the ultimate blockchain guide design to equip you with the knowledge of distributed ledgers, consensus protocols, smart contracts, DApps, cryptocurrencies, Ethereum, and more. Namecoin is the first fork of the Bitcoin source code. The key idea behind Namecoin is not to produce an altcoin but instead to provide improved decentralization, censorship resistance, privacy, security, and faster decentralized naming. Decentralized naming services are intended to respond to inherent limitations such as slowness and centralized control in the traditional Domain Name System DNS protocols used on the internet. Namecoin is used to essentially provide a service to register a key-value pair. One major use case of Namecoin is that it can provide a decentralized Transport Layer Security TLS certificate validation mechanism, driven by a blockchain-based distributed and decentralized consensus.

Disclaimer — This article is an excerpt from the book Mastering Blockchain, Third Edition by Imran Bashir, the ultimate blockchain guide design to equip you with the knowledge of distributed ledgers, consensus protocols, smart contracts, DApps, cryptocurrencies, Ethereum, and more. Namecoin is the first fork of the Bitcoin source code. The key idea behind Namecoin is not to produce an altcoin but instead to provide improved decentralization, censorship resistance, privacy, security, and faster decentralized naming.
Decentralized naming services are intended to respond to inherent limitations such as slowness and centralized control in the traditional Domain Name System DNS protocols used on the internet. Namecoin is used to essentially provide a service to register a key-value pair.
One major use case of Namecoin is that it can provide a decentralized Transport Layer Security TLS certificate validation mechanism, driven by a blockchain-based distributed and decentralized consensus. It is based on the same technology introduced with Bitcoin, but with its own blockchain and wallet software. Secure storage and transfer of names keys 2. Attachment of some value to the names by attaching up to bytes of data 3. Production of a digital currency Namecoin. Namecoin also, for the first time, introduced merged mining, which allows a miner to mine on more than one chain simultaneously.
The idea is simple but very effective: miners create a Namecoin block and produce a hash of that block. Then, the hash is added to a Bitcoin block and miners solve that block at equal to or greater than the Namecoin block difficulty to prove that enough work has been contributed toward solving the Namecoin block.
The mining task is to solve Bitcoin blocks whose scriptSig coinbase contains a hash pointer to Namecoin or any other altcoin block.
This is shown in the following diagram:. If a miner manages to solve a hash at the Bitcoin blockchain difficulty level, the Bitcoin block is built and becomes part of the Bitcoin network. In this case, the Namecoin hash is ignored by the Bitcoin blockchain. On the other hand, if a miner solves a block at the Namecoin blockchain difficulty level, a new block is created in the Namecoin blockchain. The core benefit of this scheme is that all the computational power spent by the miners contributes toward securing both Namecoin and Bitcoin.
Even though Namecoin can be mined independently, they are usually mined as part of Bitcoin mining by utilizing the merged mining technique, as explained earlier. This way, Namecoin can be mined as a by-product of Bitcoin mining. Solo mining is no longer profitable, as is evident from the following difficulty graph; instead, it is recommended to use merged mining, use a mining pool, or even use a cryptocurrency exchange to buy Namecoin:.
Various mining pools also offer the option of merged mining. This allows a miner to mine primarily Bitcoin but also, as a result, earn Namecoin too. Another method that can be used to quickly get some Namecoins is to swap your existing coins with Namecoins; for example, if you already have some bitcoins or another cryptocurrency that can be used to exchange with Namecoin. This service allows conversion from one cryptocurrency to another using a simple user-friendly interface.
First, the deposit coin is selected, which in this case is Bitcoin, and the coin to be received is selected, which is Namecoin in this case. In the top edit box, the Namecoin address where you want to receive the exchanged Namecoin is entered.
In the second edit box, at the bottom, the Bitcoin refund address is entered, where the coins will be returned to in case the transaction fails for any reason. The exchange rate and miner fee are calculated instantly as soon as the deposit and exchange currency are chosen.
Once Start Transaction is clicked, the transaction starts and instructs the user to send the bitcoin to a specific Bitcoin address. When the user sends the required amount, the conversion process starts, as shown in the following screenshot. The preceding screenshot shows that after sending the deposit, the exchange occurs and finally an All Done!
A few other order details are displayed on the page, such as what currency was deposited and what was received after the exchange. In this case, it is a Bitcoin to Namecoin exchange. There are a few other options, such as Email receipt, which can be invoked to receive a receipt of the transaction via email. When the process completes, the transactions can be viewed in the Namecoin wallet, as shown here:. It may take some time usually around 1 hour to confirm the transactions; until that time, it is not possible to use the Namecoins to manage names.
However, when Namecoins are available in the wallet, the Manage Names option can be used to generate Namecoin records. Namecoin records are in the form of key-value pairs. A general Namecoin name can be an arbitrary binary string up to bytes long with 1, bits of associated identifying information.
A record on a Namecoin chain is only valid for around days or 36, blocks, after which it needs to be renewed. Namecoin also introduced. Namecoin wallet software, as shown in the following screenshot, can be used to register. The name is entered and, after the Submit button is pressed, it will ask for configuration information, such as DNS, IP, or identity:.
As shown in the following screenshot, masteringblockchain will register as masteringblockchain. In this article we saw a detailed introduction to NameCoin, the first fork of the Bitcoin source code.

Posts Comments. Namecoin is a Bitcoin-like cryptocurrency that aims to create a secure decentralized namespace — that is, an online system that maps names to values, but without the need for a central authority to manage the mappings . In a new paper to be presented at WEIS , we report the results of an empirical study of Namecoin. What is Namecoin? In addition to standard Bitcoin features such as sending coins, Namecoin includes support for additional operations which allow users to register names and associate values with those names.

Exploring Primecoin: An Alternative Cryptocurrency Project
Namecoin is a cryptocurrency similar to Bitcoin, but differs in its ability to store data within its own blockchain transaction database. Namecoin is a cryptocurrency that was introduced on April 18, that acts as a decentralized domain registry service and domain name system. Namecoin was the first fork of Bitcoin, and shares many properties associated with Bitcoin. The blockchain infrastructure of Namecoin allows its domain name registry service to be censorship resistant and unaffected by activity tracking issues associated with non-blockchain based domain registry services. Just like Bitcoin, Namecoin uses the same source code, proof-of-work protocols, and is also limited to 21 million coins.

Bitcoin Stack Exchange is a question and answer site for Bitcoin crypto-currency enthusiasts. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. I want to keep some NMC offline. Is there a way to generate an offline wallet like bitaddress. I'd check out the python library Coinkit - it's for generating cryptocurrency wallets Bitcoin, Namecoin, Litecoin, Peercoin, Primecoin, Dogecoin and a bunch of others are currently supported. Someone could modify that source code to work with namecoin, but in the meantime here is a workaround:. Open namecoin-QT and copy the address you want to export the private key for into the clipboard.
How to buy, sell and trade Namecoin (NMC)
Namecoin is an experimental open-source technology which improves decentralization, security, censorship resistance, privacy, and speed of certain components of the Internet infrastructure such as DNS and identities. It was first to implement merged mining and a decentralized DNS. Lots of awesomeness occurred.

Against censorship. In information we trust. A trust anchor for the Internet. Supporting free speech. Decentralized secure names.
Charles Babbage did his part to make the mechanical computer a reality. Of course I learned a little more about bash this round Tested on a fresh install of Ubuntu The bankonmeOS project goal is simple I shortened the name of the file and might regret this later. Likely will have to date stamp the file for future releases.
Ledger is currently the most popular cryptocurrency hardware wallet, and a lack of Namecoin support for Ledger does not look good for those who want to hodl Namecoin. This task first involves adding support to Ledger devices to manage Namecoins themselves, and then extending this functionality to handle Namecoin assets domains, identities, etc. Electrum-NMC, the de-facto client for SPV transactions, currently does not support anything beyond basic coin transfers.
