Massa and case of eco-friendly blockchain

Blockchain technology has been continuously criticized for significant energy usage and a large carbon footprint. Cryptocurrency, in particular, has been a sore point with environmentalists. Bitcoin, for instance, is famed for consuming more electricity in a year than entire nations and being a reason of electricity outing in some regions of China, to the point that mining has been declared illegal.

Massa unique architecture makes it eco-friendly and allows to reduce carbon footpint immensely by comparison with other blockchains out there.

Proof-of-Stake

Bitcoin uses with Proof-Of-Work (PoW) consensus algorithm - each node has to "mine" transactions to upkeep the network and that process is using a lot of energy. So much so that some Bitcoin miners went bankrupt with the price drop of token because they simply could not pay huge electricity bills.

Massa is using Proof-Of-Stake (PoS) consensus algorithm, which is by far less demanding on the energy consumption. As a consensus algorithm, PoS uses validators that have a specific stake, which is a minimum amount of cryptocurrency tokens on the blockchain. The stake held by validators is locked into a smart contract on the cryptocurrency's blockchain to help maintain the required amount of cryptocurrency tokens.

Validators are rewarded by the cryptocurrency, typically with new tokens for participating in the PoW effort. If a validator fails to properly validate a transaction, the stake can be at risk from a reactive action known as slashing, whereby several tokens are revoked. PoS requires significantly less energy and computing power than the PoW approach. PoS also has the potential to be faster than PoW, as well as provide more scalability because it requires less computing power to achieve consensus and validate a transaction.

Storage Costs

In Massa the ledger is shared across all nodes of the network. Everyone can store data until the ledger reach 1TB. At first glance this limitation does not seem to do much. But actually it solve several problems: it allow to significantly reduce deterioration of hard disk drive. This leads to lesss resources consumption in the long run, all while simultaneously mitigating high energy usage than other blockchain that constantly require increase in disk space and reducing carbon footprint.

Carbon offset

A carbon offset credit is a transferrable instrument certified by governments or independent certification bodies to represent an emission reduction of one metric tonne of CO2. With development of blockchain technology, such as Massa, credits can be easily traded by a person or organization in the form of NFT or tokens.

Conclusion

The quest to make blockchain eco-friendly is in it's early stage and still has a long way to go. Massa is well equipped to tbecome the flagman solution for the zero-emission future.
