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 selection behind lots of the common 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 operating mining rigs, the fixed have to replace tools and environmental considerations led to the PoW mannequin falling out of favor with many.

In consequence, initiatives trying 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 provide a extra environmentally and economically pleasant strategy to PoW, whereas additionally aiming to construct Internet 3.0.

Let’s check out a number of the initiatives that permit individuals to contribute their assets 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 world community of low-energy wi-fi “hotspots” that broadcast knowledge 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 reliable 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 super progress all through 2021. At present, there are greater than 309,000 nodes in operation.

Extra lately, 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 provider to affix the Helium community and supply 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) due to the usage of braided chains.

In contrast to the highest PoW cryptocurrency Bitcoin, Kadena additionally presents good contract capabilities just like these discovered on Ethereum and options its personal good contract programming language known as Pact.

Being good contract succesful implies 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 cost processors.

A few of the targets of the mission have been to handle the key points plaguing the Ethereum community reminiscent of 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 gasoline funds on behalf of its consumer 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.

Not too long ago, 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 crew behind Kadena additionally has plans so as to add cross-chain help for different common blockchain networks together with Terra, Polkadot, Celo and Cosmos.

Information from Cointelegraph Markets Pro 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 centered on scalable decentralized cloud infrastructure for Internet 3.0 purposes.

In accordance with the mission, the Flux ecosystem is comprised of a set of decentralized computing companies 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 operating “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 mission launched “Mild Nodes,” which allow Flux nodes to be managed utilizing gentle wallets in order that operators can begin and monitor node metrics from any machine able to operating the FluxNodes app.

Information from Cointelegraph Markets Pro 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 initiatives within the crypto ecosystem, these three examples present that it nonetheless has lots to supply as a result of the brand new platforms are environmentally pleasant and economically sustainable.
