Green

By designing a unique, proprietary validator system we have created what we believe is the most environmentally friendly and cost-accessible blockchain on the planet. We’d love to show you how we are so efficient…

The Unique Electroneum
Validator Model

Blockchains operate on lots of different models. The very first, Bitcoin, is hugely energy inefficient, partly by design. As blockchains have advanced they have reduced energy usage, but still have a tendency to use large (some would say vast) amounts of electricity.

The electricity consumption problem comes from the extremely large number of validators (computers that help maintain the blockchain) that it takes to secure the blockchain with most models.

Smarter. Faster. Greener.

By taking a different direction on security Electroneum
has achieved three things:

Speed. Our system is orders of magnitude
faster whilst just as secure.

Nearly every blockchain can have anonymous validators. Nobody knows who the validators are. This is excellent for wider distribution and availability but terrible for electrical use, and security comes through a huge amount of anonymous operators and most of them are working for the good of the blockchain (a few of them are bad actors trying to steal everything).

Electroneum has a network of KNOWN validators. We KYC our validators and have a clever system that shuts them down if they start doing anything bad (it would never be them, but imagine if they got hacked and someone gained access to the validator they run). By knowing who our validators are we need very tiny amounts of redundancy, allowing maximum efficiency. Being an Electroneum validator operator is open to NGOs, Foundations, Universities and in some instance other blockchain projects that work with us.

To give an idea of just how much electricity this saves we’ve provided some calculations below.

Electroneum has 32 validators (a number that can scale if required by sheer computational requirement, but can handle a 50x increase in blockchain usage from here).

Solana has over 3000 validators.

Ethereum has over a million validators.

It’s impossible to be 100% accurate when calculating blockchain energy usage, however it’s relatively easy to find out how many validators are running. We just don’t know what type of server (computer) they are running. As such, we are working on the assumption that a validator uses 150w of electricity 24 hours per day. This figure is probably conservative because one of the features of Ethereum is called slashing and it financially penalizes validators that don’t operate well or maliciously and as such people tend to run more powerful equipment than strict minimums. It all works out fairly though as a ratio, because we’ve used the same power figures for each blockchain network and just multiplied the power by the number of validators. Just for fun we’ve included Bitcoin, which works in a different way altogether and requires incredibly powerful machines to solve a mathematical puzzle. The energy of Bitcoin is not being consumed to operate the network – just to secure the network. As an anonymous security system it is mathematically superb, but from an ecological perspective it’s rather troubling. We will just say that there are great projects out there that are taking the heat generated from Bitcoin mining and heating people’s homes and other solutions to the waste problem, so hopefully we see more of that in the future.

A Comparison of Blockchain Power Consumption

  • We’ve used a typical low-power Dell server consuming 150 W.
  • The same server specification is used for each network validator.
  • Validator counts were accurate as of 5th October 2025.
Network Validators × Power Total Power Yearly Energy
Electroneum 32 × 150 W 4.8 kW 42 MWh/year
Solana 3,000 × 150 W 450 kW 3.94 GWh/year
Ethereum 1,000,000 × 150 W 150 MW 1.31 TWh/year

Bitcoin has around 3.8m high power mining rigs which reportedly use 194.83 TWh/year

If a household uses only 4MWh per year (a smaller or conservative power household – the average USA household consumes 10MWh per year EIA 2024)

  • 10 households equivalent for Electroneum Blockchain
  • 985 households equivalent for Solana Blockchain
  • 327,500 households equivalent for Ethereum Blockchain
  • 48.7 million households for Bitcoin — an entire country!
