The Most Sustainable Cryptocurrency

At SafeCoin people are all about efficiency, period

We believe in global safety and security, we believe everyone has a role in protecting our environment. Safecoin was built from the ground up with energy efficiency in mind. With great performance comes great responsibility. By putting our communities and our environment first, anything is possible.

Energy usage comparison

First of all let's have a look at the energy required for a single network transaction.

SafeCoin greatly appreciates and admires Solana's technology and so the following energy comparison is based upon Solana’s Energy Use Report: March 2022. We also added VISA transaction details for a more relatable real-life comparison.

Fun Facts

Have you ever been involved in blockchain energy consumption discussions? Bitcoin and Ethereum are usually the main subjects, however it can be hard for one to wrap their head around the actual cost to power these blockchains. So, at your next dinner party you can mention some of these fun facts based upon our measurements.

17760 Transactions
with a single battery

A regular AA Battery with 0.00444 kWh (2.96Ah with 1.5V) capacity could power 17,760 SafeCoin transactions, almost 6 Solana transactions, and 3 VISA transactions. Yet, for a single Bitcoin transaction, one would need at least 334,213 batteries.

Moving money globally

The 232.5 billion VISA transactions per year equate to more than $2.7 billion USD in costs at the average price of Electricity for industrial usage in the US (7.83$/kWh). With SafeCoin, this would only cost $455 million per year while with Bitcoin, one would need 12x the world's total electricity consumption to acheive this.

Safe 98%
of CO2 Emissions

Assuming the equivalent of 0.85 pounds of CO2 emissions per kWh (, yearly VISA transactions contribute to about 146 million metric tons of greenhouse gas emissions – equal to the 2020 traffic sector in Germany. By using SafeCoin, one could reduce CO2 emissions by more than 98%!

Metering setup: How do we measure?

Running between 2000-3000 TPS at an average of 2800 TPS and measuring the power draw from a validator supporting the network. The average power during the test was determined to be approximately 56W. Solana's network runs at an average of 2000 TPS and has a baseline power draw of 1000W. From the initial tests, we can confirm SafeCoin has an energy efficiency of approximately 0.00000025 kWh/txn compared to Solana at 0.000752 kWh/txn. This makes SafeCoin the world's most energy efficient blockchain.

A quick basic rundown from our first test (much more data is coming):

Watts - W | Joules - J | Transaction - TXN | Transactions per second - TPS | Kilowatt-hour - kWh

56 W = 56 J/s
(56 J/s) / 2800 TPS = 0.02 J/TXN per validator

Our network currently consists of 45 active validators, so:

45 validators * 0.02 J/TXN per validator = 0.9 J/TXN for the entire SafeCoin network.**
1 kWh = 3600000 J
(0.9J/TXN) / (3600000 J/kWh) =  0.00000025 kWh/TXN

**Note: These tests were conducted on an inefficient desktop whereas most of the active validators supporting the network run on servers which would likely reduce the energy consumptions even further.
