Hardware infrastructure, once the foundation of computing giants like IBM, has become an abstract commodity thanks to cloud computing, virtualization, and containerization.Through large service providers like Amazon Web Services, Microsoft Azure, and Google Cloud Platform, or smaller ones like DigitalOcean, Linode, and Vultr, developers can now launch and destroy servers or mere functions using "serverless" architecture, without significant cost.Teran McKinney, a Texas-based systems engineer with a professed fondness for Ayn Rand, is taking disposable infrastructure a step further with a service called SporeStack that allows developers to deploy servers anonymously, paid for in Bitcoin.McKinney describes SporeStack, introduced earlier this month, as a JSON API for launching servers.The software allows those with Bitcoins to purchase a temporary server by sending a payment through coinfee.net, a Bitcoin-based payment processor McKinney developed.Doing so requires just a few command line instructions.

SporeStack creates servers lasting from 1 to 28 days hosted by Vultr, but without the need for a Vultr account.McKinney, in an email interview with The Register, acknowledged that the service is slightly more expensive than Vultr through a standard account – a 768MiB SporeStack server for a month costs just under $10, compared to $5 on Vultr – though there's no sales tax for SporeStack.bitcoin ne olacakThe ability to launch servers without providing personal information sounds like an invitation to spam, but McKinney said he doubted the economics would be appealing.ethereum central bank"I used to work at Rackspace," said McKinney.bitcoin at subway"While I'm sure it happened, I cannot recall a time that a spammer (or similar) used our servers and paid.bitcoin bull or bear

They would sign up with a fake credit card and get a month of free service, unless they were shut down early (and they usually were)."The benefit of Bitcoin, McKinney said, is the lack of built-in transaction reversibility, which makes certain kinds of fraud more difficult.bitcoin calc miner"There has been some interest which seems more grey, though I've had no reports of misuse," said McKinney.bitcoin etude"Since they are paying up front, they are risking losing out if the server has to be shut down for spam, denial of service, etc."bitcoin mining picThe service has not been designed for Tor-level anonymity.bitcoin python serverIf someone launches SporeStack without a VPN or Tor, that person's IP address could be logged somewhere.upgrade bitcoin qt

"I don't log IP addresses, but in theory, someone could be watching that," McKinney said.But SporeStack's reason for being has more to do with convenience than anonymity.McKinney sees the ability to spin up servers without an account as a selling point.He suggests SporeStack might be useful for doing network testing in another geographical area or for creating a VPN for the day in order to work in a coffee shop without worrying about the security of the Wi‑Fi."I've been working towards launching a site that uses SporeStack to build a server just for you, and sends your browser an OpenVPN configuration file," said McKinney."It should launch OpenVPN and connect you right to it.It'd probably cost about a dollar for the day, maybe less."McKinney sees SporeStack enabling development and infrastructure scaling without significant upfront capital."If you are clever, you could use a Coinfee split payment to pay for your server and take a cut at the same time," he said."You would never pay for the server – the user would."

Servers are only the beginning, said McKinney, who hopes to spur demand for payments via APIs.The idea is that people would not need accounts, the associated databases, or passwords.Many large technology companies have started to explore disposable servers, McKinney said."Rather than having a server for a long time and upgrading it, they just become proficient at deleting and creating," he said.Jump to: , Contents 1 2 3 4 5 6 7 8 9 C Run bitcoind or bitcoin-qt -server.You can control it via the command-line bitcoin-cli utility or by HTTP JSON-RPC commands.You must create a bitcoin.conf configuration file setting an rpcuser and rpcpassword; see Running Bitcoin for details.A list of RPC calls will be shown.If you are learning the API, it is a very good idea to use the test network (run bitcoind -testnet and bitcoin-cli -testnet).Running Bitcoin with the -server argument (or running bitcoind) tells it to function as a HTTP JSON-RPC server, but Basic access authentication must be used when communicating with it, and, for security, by default, the server only accepts connections from other processes on the same machine.

If your HTTP or JSON library requires you to specify which 'realm' is authenticated, use 'jsonrpc'.Bitcoin supports SSL (https) JSON-RPC connections beginning with version 0.3.14.See the rpcssl wiki page for setup instructions and a list of all bitcoin.conf configuration options.Allowing arbitrary machines to access the JSON-RPC port (using the rpcallowip configuration option) is dangerous and strongly discouraged-- access should be strictly limited to trusted machines.To access the server you should find a suitable library for your language.See the proper money handling page for notes on avoiding rounding errors when handling bitcoin values.python-jsonrpc is the official JSON-RPC implementation for Python.It automatically generates Python methods for RPC calls.However, due to its design for supporting old versions of Python, it is also rather inefficient.jgarzik has forked it as Python-BitcoinRPC and optimized it for current versions.Generally, this version is recommended.While BitcoinRPC lacks a few obscure features from jsonrpc, software using only the ServiceProxy class can be written the same to work with either version the user might choose to install: The latest version of python-bitcoinrpc has a new syntax.

By default the client will use the configuration in $HOME/.bitcoin/bitcoin.conf or you can instead specify a URI like this: Here is a usage example: The JSON-RPC PHP library also makes it very easy to connect to Bitcoin.For example: Note: The jsonRPCClient library uses fopen() and will throw an exception saying "Unable to connect" if it receives a 404 or 500 error from bitcoind.This prevents you from being able to see error messages generated by bitcoind (as they are sent with status 404 or 500).The EasyBitcoin-PHP library is similar in function to JSON-RPC PHP but does not have this issue.The easiest way to tell Java to use HTTP Basic authentication is to set a default Authenticator: Once that is done, any JSON-RPC library for Java (or ordinary URL POSTs) may be used to communicate with the Bitcoin server.Instead of writing your own implementation, consider using one of the existing wrappers like BitcoindClient4J, btcd-cli4j or Bitcoin-JSON-RPC-Client instead.The JSON::RPC package from CPAN can be used to communicate with Bitcoin.

You must set the client's credentials; for example: The btcrpcclient package can be used to communicate with Bitcoin.You must provide credentials to match the client you are communicating with.The communication with the RPC service can be achieved using the standard http request/response objects.A library for serializing and deserializing Json will make your life a lot easier: /json ) is a high performance JSON package for .NET.It is also available via NuGet from the package manager console ( Install-Package Newtonsoft.Json ).The following example uses Json.NET: There is also a wrapper for Json.NET called Bitnet (https://sourceforge.net/projects/bitnet) implementing Bitcoin API in more convenient way: /GeorgeKimionis/BitcoinLib) which is also available via NuGet from the package manager console (Install-Package BitcoinLib).Querying the daemon with BitcoinLib is as simple as: You can also send commands and see results using cURL or some other command-line HTTP-fetching utility; for example: You will be prompted for your rpcpassword, and then will see something like: clj-btc is a Clojure wrapper for the bitcoin API.
