Blockchains: Which is Most Sustainable?

As stated earlier, non-fungible tokens (NFTs) are now more popular than ever before. Non-interchangeable units provide an excellent way of selling any digital item. For instance, the breakthrough of the NFTs in arts, fashion, and toys. This also has led to the revival of the ICURY project. This post will explain and compare which blockchain is the most sustainable.

The current crypto landscape hype leads to multiple blockchains available on the market. But, the challenge is to figure out which ones are the most ‘sustainable blockchains.’ For example, the ICURY project was initially built on the Ethereum blockchain. The goal is to create NFTs by attaching a unique Icecat product barcode as an image. In addition, I am exploring two other popular blockchains, Polygon and Solana. 

Blockchain Comparison Table

I compare three blockchains: Ethereum, Polygon, and Solana in the comparison table below.

Ethereum, Polygon or Solana?

To conclude, Ethereum has the most pivotal role in building the backbone of decentralized finance. For that reason it has a firm footing in the industry. The Ethereum blockchain scores are, for example, high on security and stability parameters. But on the other hand, it scores low on throughput and fee of transactions. On the other hand, Solana and Polygon are relatively new. That is why it is hard to say who will win in the long term.
