## Building on Polygon&#x20;

Polygon, formerly the Matic network, is an innovative protocol and development tool that merges the best elements of the Ethereum blockchain and sovereign blockchains into a full-fledged multi-chain system. Polygon has the same security and interoperability as the Ethereum blockchain but is cheaper and faster to use.&#x20;

We've studied 10 blockchains before we made the choice of building Pooky on Polygon. Here are a few reasons why:

### Quality&#x20;

* Polygon has one of the lowest block times, close to 2 seconds. This is incredibly important in a gaming application where reactivity matters for the end user. Combined with a 7500+ block per second capacity, this ensures quick responses to the end user.&#x20;
* Polygon has a great ecosystem, a great reputation in the gaming world with a large number of Github contributors (only bested by Ethereum at the time of our study)&#x20;
* Polygon has very low gas fees. Polygon uses Proof of Stake (PoS) - more on that in the Sustainability section.&#x20;

### Sustainability&#x20;

**Energy consumption comparison between PoW blockchains and Polygon**&#x20;

According to estimates, the biggest PoW blockchains can consume between 35–140 TWh of electricity per year, with a continuous draw of between 3–15 GW. If they were countries, the two biggest PoW blockchains would be ranked 27th in yearly energy consumption — above the likes of Sweden, Vietnam and Argentina.&#x20;

By contrast, Polygon’s validators consume approximately 0.00079TWh of electricity per year, with an approximate continuous draw of 0.00009GW.&#x20;

These are orders of magnitude below the energy consumption of major PoW blockchain networks.

&#x20;To put Polygon’s eco-friendliness in perspective, Polygon’s yearly energy consumption is equivalent to&#x20;

* Greenhouse emissions from 122 passenger vehicles driven for one year
* CO2 emissions from 101 homes’ electricity use for one year

**A Green Blockchain**&#x20;

On April 19, 2022, The Polygon network released its Green Manifesto: A Smart Contract with Planet Earth. The manifesto announced Polygon’s commitment to become carbon neutral and climate positive this year. It also committed $20 million to offset its carbon footprint and purchase additional credits.
