Tezos blockchain notes power savings after PoS switch: PwC report

Tezos, a privacy-focused blockchain network, released its carbon footprint report from PricewaterhouseCoopers Advisory SAS, a French member firm of the PwC network. The PwC report reflects drastic improvements in energy efficiency for Tezos since moving from a proof-of-work (PoW) to a proof-of-stake (PoS) mining consensus. The PwC report highlighted a significant decline in carbon emission by Tezos network despite a rise in network activity. The Tezos blockchain accounted for 50 million transactions while, according to the report, the whole network constituted an energy footprint of 17…

Proof Of Work Useful Beyond Bitcoin

Anyone who has studied bitcoin for a while knows that proof-of-work in bitcoin mining is the key to the security and to the unforgeable nature of the protocol. Bitcoin mining in 2021 requires that miners use purpose-built computers [called ASIC’s] to convert real-world energy [more than 50% of which is renewable and stranded energy] into encrypted digital monetary energy. By using this proof-of-work and following consensus rules, bitcoin miners (and node operators) secure this decentralized network one block at a time approximately every ten minutes. Some have even called it triple-entry…

DeFi risks and protocol safety with Tarun Chitra of Gauntlet Network

In this week’s interview with Alex Fazel of crypto edutainment channel Cryptonites, Tarun Chitra discusses the difference between Proof of Stake (PoS) vs Proof of Work (PoW), layer-one protocols, and the risks involved with blockchain tools.Chitra is CEO at Gauntlet Network, the financial modeling and simulation platform for blockchains, which he co-founded with Rei Chiang in 2018.For the past seven years, he has been working on simulation-based R&D at the intersection of high-performance computing and AI. His research includes some of the first academic papers examining the economic…

(Consider tuning in to the Annual WZBC Pow Wow, and reports from the yearly Plymouth MA protest, or a similar offering, in a community near you, this year.)
Manifest Destiny
The dictionary defines Manifest Destiny as “the 19th-century doctrine or belief that the expansion of the US throughout the American continents was both justified and inevitable.”
We are still in the midst of a long-running, historical chapter of Manifest Destiny, Entitlement, Colonialism, Climate Terror, Extreme Weather, Exploitation, Abuse of Indigenous Rights, and War, that began in this…

Swedish Regulators Propose PoW Mining Ban. State-Owned Power Company Defends It

In Sweden, financial and environmental regulators want to ban PoW mining. Unfortunately, they forgot to add Vattenfall to the email. And Sweden’s biggest green energy power company categorically rejected their claims on national public television. Ouch. This is a real-life example of the game theory that protects Bitcoin. And more evidence that proves that Bitcoin incentivizes green energy infrastructure.

Consensus Algorythms

A consensus algorithm is a process in computer science used to achieve agreement on a single data value among distributed processes or systems. Consensus algorithms are designed to achieve reliability in a network involving multiple unreliable nodes. As a result, consensus algorithms must be fault-tolerant. Lets review some of the most popular algos:

A proof of work is a piece of data which is difficult (costly, time-consuming) to produce but easy for others to verify and which satisfies certain requirements. Producing a proof of work can be a random process with low probability so that a lot of trial and error is required on average before a valid proof of work is generated.

Bitcoin uses the Hashcash proof of work system.…

Microchip Unveils Industry's Most Compact 1.6T Ethernet PHY with Up to 800 GbE Connectivity for Cloud Data Centers, 5G and AI – ELE Times

Routers, switches and line cards need higher bandwidth, port density and up to 800 Gigabit Ethernet (GbE) connectivity to handle escalating data center traffic driven by 5G, cloud services and Artificial Intelligence (AI) and Machine Learning (ML) applications. To deliver the higher bandwidth, these designs need to overcome the signal integrity challenges associated with the industry’s transition to the 112G (gigabits per second) PAM4 Serializer/Deserializer (SerDes) connectivity that is needed to support the latest pluggable optics, system backplanes and packet processors. These challenges can now be overcome with the industry’s most compact, 1.6T (terabits per second), low-power PHY (physical layer) solution from Microchip Technology Inc.


How Proof of Stake Differs From Proof of Work

Bybit Hacker Noon profile picture


Bybit is one of the fastest growing cryptocurrency derivatives exchanges, with more than a million registered users.

Privacy and security have always been a ground for debates in the crypto industry. Hence, the foundation of a consensus mechanism in the blockchain is important to sustain the network. Ultimately, these consensuses are used to achieve an agreement on a single data value among an array of distributed processes and cryptocurrencies. So, whenever there’s a system failure, a correcting mechanism is thereby correcting the errors. When comparing Proof of Stake vs Proof of Work side-by-side, the difference is pretty obvious.

Today we are all on the verge of seeing the Proof of Stake (PoS) consensus mechanism to revolutionize the existing Proof of Work (PoW).


The New Pathways for Partnership for Solar and Artificial Intelligence – Solar Magazine

Solar energy is growing in public use and support every year. It’s acclaimed across the world as a source of renewable energy that’s affordable and effective. Also, as a technology, solar energy is lighting the way to a future where the planet is cleaner and greener and one where many new jobs are created from one year to the next as a result of the renewable energy revolution. While solar power is certainly outstanding, it’s not the only emerging technology that holds immense transformational promise.

It’s no overstatement to say the greater adoption of Artificial Intelligence (AI) has the potential to fundamentally transform life as we know it for this generation and forthcoming generations. Doing so in the same way the uptake of the personal computer from the 1980s onwards did for recent generations past.

Ethereum vs Bitcoin

The essential difference between ETH and BTC is that in the former you can not only transmit money but also run SC and do DApps. This happens with EVM (Ethereum Virtual Machine), and thanks to the native language of ETH, called Solidity, which is used to write smart contracts and DApps. From there, ETH crypto-currency is used to make these apps and intelligent contracts work.

BTC is developing other tools such as RSK, which is the first open platform for intelligent contracts on BTC, and which remunerates BTC miners by allowing them to participate in the SC revolution. If it works, it could make ETH somewhat less relevant.

The RSK project started as a fork of an Ethereum codebase in 2016 and it was developed for 2 years until it was finally launched in 2018.… Read more...
