New Raspberry Pi Runs Full Bitcoin Node for $35

Published at: Feb. 3, 2015

As Bitcoin mining becomes more competitive, the hardware used becomes more sophisticated (read: spendy). The cost to run a Bitcoin node, however, is moving in the opposite direction: down.

The Raspberry Pi Foundation just released the Raspberry Pi 2 Model B. It features 1 GB of RAM and will perform “at least 6x” faster than the previous model, the B+. It sells for about US$35 and can be bought for bitcoin.

For Nodes, Cheap Hardware's Welcome

As you may know, Bitcoin miners are the ones rewarded with bitcoins for generating transaction confirmations. Nodes, on the other hand, host and transmit updated copies of the blockchain (transaction ledger), and are not compensated.

(I've always thought that this non-compensation was perhaps a flaw in Satoshi's design, but nodes I've met say they host the blockchain to add robustness and security to the network. This reasoning is sound for anyone who holds the currency, and I hope it's sustainable.)

The pseudo-altruism of Bitcoin nodes makes cheap hardware even more appealing to them. The blockchain is large and can slow down an average laptop, so keeping it on exterior hardware like a Raspberry Pi keeps one's PC unhampered.

Not the First, But Better

Redditor Introshine commented:

“I once ran a full node on a normal B model - it works but runs out of RAM very quick. With a swapfile it was do-able but not fast.

This new Version 2 B+ model has 1GB of ram and a 900Mhz quad-core. Combined with a 64GB SD card it should be able to run a bitcoind full node.”

And there may be comparable options. Redditor jerguismi commented:

“There are also other competitors to raspberry pi, for example boards called 'banana pi' and 'banana pro.'”

Have you used any other kind of exterior hardware to run a full Bitcoin node? If not, now that it's cheaper to do so, are you interested?

Bitcoin and Ethereum transaction fees sink 95% from all-time highs
The cost of using the Bitcoin and Ethereum blockchains is on the rapid decline, as evidenced by a 93%–95% reduction in average transaction fees over the past couple of months. Fees are paid to the miners who process transactions on a typical proof-of-work blockchain. The size of the fee depends on the size of the transaction in bytes and how many transactions a coin has gone through in the past (as these need to be checked every time a coin is moved). Supply and demand for space also dictate the size of a transaction fee since blockchains have limited capacity. …

Blockchain company Borderless Services Inc.: Forbes should be ‘under US ownership’
Blockchain holding group Borderless Services Inc. made headlines in late April amid reports that it had placed a $700 million bid to acquire business news publisher Forbes Media LLC. In an interview with Cointelegraph, CEO Patrick McConlogue shed light on the acquisition target and why it aligns with the organization’s overall vision. “Acquiring any company is a long process, and there are a lot of moving parts,” McConlogue wrote in an email, adding: “We are excited to participate either as owners, partners, or combined force with the other bidders. Collectively we all want Forbes back under US ownership and are …

Is Staking the Answer to Cryptocurrency’s Mining Problems?
For a tech that was supposed to be democratic and distributed in order to free financial systems from the grip of government-influenced banks and return control of the money supply to the people, cryptocurrencies have turned out to be pretty concentrated. Some 66% of all Bitcoin (BTC) mining now takes place in China, with 54% located in the southwest province of Sichuan, as a recent study revealed. Three Chinese mining pools alone are responsible for nearly half of Bitcoin’s hashrate. The days when a single Bitcoin enthusiast could crunch numbers on their home computer and land a Bitcoin reward for …

The race for semiconductors: Are crypto miners taking the lion's share?
Over the last couple of years, the world has been grappling with the lack of semiconductors, which are the substances that conduct electricity between metals and isolates. The most famous semiconductor is silicon. If correlating this concept to electronic devices, then the key semiconductors are processors and other microcircuits that are present in almost all devices that people use every day, from smartphones to cars. In 2021, semiconductors hit a world record in terms of sales. Electronics production also boomed, with hundreds of millions of complex semiconductors being devoured by gaming consoles. The number of GPUs produced grew to unseen …
