What Are Sustainable Cryptocurrencies?

Date:

Currently, the most popular sustainable coins are SolarCoin, Peercoin, and NXT. Green SolarCoin is a particularly intriguing currency since it aims to promote the usage of renewable energy sources like solar power. SolarCoin is a cryptocurrency that rewards users for generating power using solar energy.

A number of initiatives are underway to make mining more ecologically friendly and sustainable. Renewable energy sources are being used in these initiatives, as well as the development of more energy-efficient equipment. Many of these initiatives are still in their early stages, but they represent a positive step forward in the drive for environmentally friendly mining.

The start of a new age in environmentally-friendly mining?

For instance, the MineCoin project is an example of a long-term mining enterprise. MineCoin is a cryptocurrency that is designed to be mined entirely using renewable energy. It is presently being tested in beta. It is based on the Green Energy Bitcoin algorithm, which uses less energy and is, therefore, more ecologically friendly than traditional Bitcoin mining methods.

MineCoin also has a few extra features that make it more environmentally friendly than other cryptocurrency solutions. To verify transactions, proof-of-stake algorithms are utilized, which require less power than proof-of-work algorithms and are hence more energy efficient.

Another example of a sustainable mining enterprise worth noting is the HydroMiner initiative. HydroMiner is a cryptocurrency mining enterprise that generates energy using hydroelectric power. This reduces the amount of power needed by the network by eliminating the requirement for traditional mining equipment like as ASICs.

Blockchain developers and cryptocurrency supporters are making many measures to safeguard the blockchain and cryptocurrency ecosystem’s long-term health. The Crypto Climate Accord, for example, aims to have all blockchains powered by renewable energy by 2025 and has even developed a 32-page audit document to calculate the environmental impact of cryptocurrency mining activities. According to statistics recently released by the Bitcoin Mining Council, 32% of the network was mining using a 67 per cent renewable energy mix, according to the council’s report.

Sustainable coins use different consensus mechanisms

Proof of Elapsed Time

The blockchain network’s consensus process generates a random wait time for each node in the network, following which each node goes to sleep for the specified amount of time. The participant with the least amount of waiting time then commits a new block to the blockchain, spreading the vital information to all other peers involved. It is similar to the PoW method, but since the miner’s CPU is switched down, it is more efficient. Permissioned blockchains, such as the Hyperledger Sawtooth blockchain, generally use it.

The industry saves at least 50% on energy usage, reduces carbon footprints, reduces e-waste generated, and becomes more ecologically friendly and sustainable by applying any of these solutions.

Green cryptocurrencies, which are presently in development, are based on unique ways that reduce blockchain technology’s carbon impact. In the search for solutions that would lead to increased environmental sustainability, many of these factors might be applied to existing, more polluting cryptocurrencies. One such example is Ethereum, which powers the majority of non-fungible tokens (NFTs). The Ethereum blockchain wants to reduce its energy consumption by 99.5% by using a Proof-of-Stake (PoS) consensus procedure.

Coins with a low carbon footprint

  • Stellar
  • Algorand
  • Tezos
  • Nano
  • Cardano 
  • IOTA

Let’s take, for example, Algorand. Permissionless Proof of Stake is Algorand’s consensus mechanism. It is based on the Byzantine method for consensus. In terms of Proof of Stake, Algorand picks validators at random based on their stake. Validators must pay a one-time deposit and be rewarded via transaction fees. To guarantee the decentralized nature of the network, each node wishing to join as a validator must make an independent deposit (the size can vary according to each specific consensus).

Carbon Credits in the Future

The use of state carbon credits for bitcoin mining firms might result in their acquiring carbon credits from other businesses, lowering world emissions, or converting to cleaner energy to sell their own credits, reducing global emissions.
