3 Proof-of-work protocols focused on building Web 3.0

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 lots of the well-liked tasks within the early fledgling years of the crypto ecosystem.

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

Because of this, tasks 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 tasks that supply a extra environmentally and economically pleasant strategy to PoW, whereas additionally aiming to construct Net 3.0.

Let’s check out a number of the tasks that enable folks 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) units 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 respectable wi-fi protection and that miners obtain the platform’s native HNT token for serving to to offer protection for the community.

The Helium community noticed large development all through 2021. At present, there are greater than 309,000 nodes in operation.

Extra just lately, the Helium community expanded its capabilities by including assist 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 tv for pc tv firm Dish Community, making Dish the primary main provider 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 value 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 presents sensible contract capabilities much like these discovered on Ethereum and options its personal sensible contract programming language referred to as Pact.

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

Among the targets of the challenge have been to deal with the foremost points plaguing the Ethereum community akin to excessive transaction prices and community congestion, and claims to supply marginal transaction charges for customers whereas additionally introducing a “crypto fuel station” function that lets companies create accounts that exist to fund fuel funds on behalf of its person base when sure situations 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.

Not too long ago, KDA launched a wrapped model of its token referred to as wKDA that’s able to interacting with all Ethereum Digital Machine- (EVM-) suitable networks and their related DeFi protocols.

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

Knowledge from Cointelegraph Markets Professional and TradingView exhibits 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 Net 3.0 functions.

In line with the challenge, the Flux ecosystem is comprised of a collection of decentralized computing companies and blockchain-as-a-service options which provide an Amazon Net Companies-like improvement atmosphere, in addition to the FluxOS second-layer working system that’s able to operating “any hardened dockerized utility.”

The Flux community makes use of the ZelHash algorithm, which is a GPU minable implementation of Equihash 125,4 and may be mined by way of a Flux neighborhood pool or on quite a lot of third-party swimming pools created by groups that assist 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 “Mild Nodes,” which allow Flux nodes to be managed utilizing mild wallets in order that operators can begin and monitor node metrics from any system able to operating the FluxNodes app.

Knowledge from Cointelegraph Markets Professional and TradingView exhibits that since Oct. 24 when it was revealed that Apple Pay can 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 tasks within the crypto ecosystem, these three examples present that it nonetheless has quite a bit to supply as a result of the brand new platforms are environmentally pleasant and economically sustainable.
