How Consensus Algorithms Solve Issues with Bitcoin's Proof of Work
It used to be that bitcoin mining was a community affair, but the process of confirming bitcoin transactions now requires an immense amount of hashing power specific to the SHA-256 mining algorithm. As a result, the amount of electricity required to process and verify transactions has reached an immense scale. In the early days, when the first users like the late Hal Finney began experimenting with bitcoin, users could just open the early bitcoin client and let their CPU whir away, creating bitcoins for fractions of a penny. By contrast, mining now requires tens of thousands of dollars in....

Since the transition from proof-of-work (PoW) to proof-of-stake (PoS), ethereum cannot be mined and miners are now dedicating hashrate to different PoW chains. Since ethereum can no longer be mined, the most profitable PoW consensus algorithms are Kadena, Scrypt, and Cuckatoo32. Five days ago, before The Merge, the consensus algorithm Ethash was the most profitable, as the top miner raked in $79.53 per day in profits. Today’s top mining rig, with Ethereum out of the picture, accrues roughly $69.41 per day mining kadena. Today’s Top 7 Mineable PoW Algorithms Include Kadena,....
The cryptocurrency world has been adapting to the current demands and generating new consensus algorithms with better functionalities. The first consensus algorithm was the Proof of Work algorithm, but today there are various protocols such as Proof of Stake and Proof of Space. Specific consensus algorithms offer certain advantages over others. For example, the Proof of Stake algorithm is a more secure, faster and cheaper consensus protocol than Proof of Work. LaneAxis, the world’s freight brokerless direct freight network, utilizes a Proof of Stake algorithm to ensure quick transactions....
Gaining a deeper understanding of a popular — but widely misunderstood — concept in blockchain technology: the consensus algorithm. Cointelegraph is following the development of an entirely new blockchain from inception to mainnet and beyond through its series Inside the Blockchain Developer’s Mind. In previous parts, Andrew Levine of Koinos Group discussed some of the challenges the team has faced since identifying the key issues they intend to solve and outlined three of the “crises” that are holding back blockchain adoption: upgradeability, scalability and governance. This series is....

Algorand's PPoS consensus algorithm distinguishes it from other blockchain networks that help solve blockchain trilemma. What is Algorand?Algorand is a blockchain network created in 2017 by Silvio Micali, an MIT professor who won the Turing Award for his work in cryptography. Algorand is a decentralized permissionless blockchain protocol that anyone can use to develop applications and transfer value. The Algorand protocol is powered by a novel consensus algorithm that enables fast, secure and scalable transactions.Algorand addresses the common issues that most older blockchains have,....
