The proof-of-work (PoW) consensus mannequin is the mechanism that kicked off the revolution that launched Bitcoin (BTC) in 2009 and it was the mannequin of alternative behind most of the standard initiatives within the early fledgling years of the crypto ecosystem.

As time progressed, different consensus fashions like proof-of-stake (PoS) rose in reputation, particularly as the price of working mining rigs, the fixed must replace gear and environmental considerations led to the PoW mannequin falling out of favor with many.

Consequently, initiatives seeking to make use of a proof-of-work mannequin have needed to adapt to remain aligned with the calls for of the broader market. This has led to the emergence of initiatives that supply a extra environmentally and economically pleasant method to PoW, whereas additionally aiming to construct Internet 3.0.

Let’s check out a few of the initiatives that enable individuals to contribute their sources towards securing the community and earn a yield within the course of.


Helium is a decentralized blockchain-powered community for the Web of Issues (IoT) gadgets that makes use of a worldwide community of low-energy wi-fi “hotspots” that broadcast information through radio waves to be recorded on its blockchain.

The community makes use of a brand new work algorithm that has been dubbed “proof-of-coverage” to validate that hotspots are offering reputable wi-fi protection and that miners obtain the platform’s native HNT token for serving to to supply protection for the community.

The Helium community noticed great progress all through 2021. At the moment, there are greater than 309,000 nodes in operation.

Extra not too long ago, the Helium community expanded its capabilities by including help for 5G wi-fi capabilities which included the launch of a brand new line of miners able to transmitting the 5G sign.

On Oct. 26, Helium introduced that it had partnered with the satellite television company Dish Network, making Dish the primary main service to hitch the Helium community and provide its subscribers the chance to run Helium nodes in trade for HNT tokens.

Shortly after these developments, HNT worth rallied to a brand new all-time excessive at $53.11 on Nov. 9.


Kadena (KDA) is a scalable PoW layer-one blockchain protocol that claims to be able to processing as much as 480,000 transactions per second (TPS) because of the usage of braided chains.

Not like the highest PoW cryptocurrency Bitcoin, Kadena additionally provides good contract capabilities just like these discovered on Ethereum and options its personal good contract programming language known as Pact.

Being good contract succesful signifies that the Kadena community is able to internet hosting decentralized finance (DeFi) and nonfungible token (NFT) protocols, in addition to a bunch of different specialised initiatives from stablecoins to fee processors.

A number of the targets of the challenge have been to handle the foremost points plaguing the Ethereum community resembling excessive transaction prices and community congestion, and claims to supply marginal transaction charges for customers whereas additionally introducing a “crypto gas station” feature that lets companies create accounts that exist to fund fuel funds on behalf of its person base when sure circumstances are met.

Kadena makes use of the Blake (2s-Kadena) algorithm as its consensus mannequin which requires native ASIC miners and can’t be mined utilizing GPUs or CPUs.

Just lately, KDA launched a wrapped model of its token known as wKDA that’s able to interacting with all Ethereum Digital Machine- (EVM-) suitable networks and their related DeFi protocols.

Sooner or later, the workforce behind Kadena additionally has plans so as to add cross-chain help for different standard blockchain networks together with Terra, Polkadot, Celo and Cosmos.

Knowledge from Cointelegraph Markets Pro and TradingView reveals that because of the current developments, the value of KDA had surged 1,280% from a low of $2.05 on Oct. 17 to a brand new all-time excessive at $28.44 on Nov. 11.


Flux (FLUX) is a local GPU mineable PoW protocol that’s targeted on scalable decentralized cloud infrastructure for Internet 3.0 functions.

In accordance with the challenge, the Flux ecosystem is comprised of a set of decentralized computing providers and blockchain-as-a-service options which supply an Amazon Web Services-like development environment, in addition to the FluxOS second-layer working system that’s able to working “any hardened dockerized software.”

The Flux community makes use of the ZelHash algorithm, which is a GPU minable implementation of Equihash 125,4 and may be mined by means of a Flux neighborhood pool or on quite a lot of third-party swimming pools created by groups that help the Flux mining ecosystem.

The block time on the Flux community is 2 minutes and the present block reward is 75 Flux, with 50% going to node operators and 50% going to miners.

On Nov. 9, the challenge launched “Gentle Nodes,” which allow Flux nodes to be managed utilizing gentle wallets in order that operators can begin and monitor node metrics from any gadget able to working the FluxNodes app.

Knowledge from Cointelegraph Markets Pro and TradingView reveals that since Oct. 24 when it was revealed that Apple Pay could be built-in with the Flux community’s Zelcore pockets, the value of FLUX has surged 802% from $0.33 to a brand new all-time excessive at $2.96 on Nov. 12.

Whereas the PoW mannequin of consensus is not the dominant mannequin utilized by main initiatives within the crypto ecosystem, these three examples present that it nonetheless has loads to supply as a result of the brand new platforms are environmentally pleasant and economically sustainable.
