Critics have long been wary of the crypto industry’s environmental costs. On this issue, Wu countered that "Amber is not engaged in proof-of-work mining, yet." He’s also optimistic about where the field is headed.
"Even after the unemployment rate goes down and there’s a vaccine, there’s going to be a probably substantial group of workers who are going to need support as they’re finding their way in the post-pandemic economy, because it’s going to be different in some fundamental ways," Powell said.
A drivechain or sidechain is a way for Bitcoin to express itself differently. For example, enabling blocks of different sizes on the blockchain or having zero-knowledge proofs. To provide some background, Blockstream promised sidechains in 2014.
More than 700 institutional customers — mainly large hedge funds, family offices and corporations — account for over 70% of its revenues, though its consumer-facing app has grown substantially, with over 100,000 registered users as of late. The firm launched its mobile app in the third quarter of 2020, widening its scope from institutional clients to retail consumers.
14 utilize BC to prevent unsolicited traffic coming from IoT devices positioned at the edge of the network in a trustworthy, scalable, and distributed manner. To this end, they implemented a trust list across widely distributed edge networks using BC and SDN. First, SDN controllers receive the recent updates of BC, which contains profiles of validated devices. Finally, new flow rules are installed to allow that device to communicate with the server based on an existing service profile. Then, they check whether the device is connected to their network.
However, for new nodes which have no trust score, all their new transactions need to be verified. Additionally, btc BC nodes should not be fully trusted to defend against compromised nodes. Trust-based validation. Rather than validating all new transactions submitted to BC, trust evaluation algorithms can be employed to validate a fraction of these transactions based on each node's trust score. This approach is adopted in Dorri et al. 6,7 to provide a lightweight, scalable, and efficient blockchain for cryptocurrency IoT environments.
Corey Lewandowski, Trump campaign adviser, tests positive for COVID-19, More than 130 Secret Service agents assigned to protecting the White House or President Trump are isolating after they tested positive for the coronavirus or had contact with an infected colleague, according to a new report.
Sidechains enhance programmability (the ability for developers to have more control over the types of solutions they can build), scalability (the ability of a blockchain to grow with its user base), and interoperability (the ability of different blockchain networks to connect) within the blockchain space. Sidechains – separate blockchains connected to the main blockchain network – allow developers to bring new features to blockchain platforms. The new offering from Input Output Global (IOG), crypto one of the systems companies behind Cardano, will introduce a new suite of Cardano sidechains.
"Drivechain allows Bitcoin
to create, delete, send BTC to, and receive BTC
from "Layer-2"s called "sidechains." Sidechains are Altcoins that lack a native "coin" – instead, pre-existing coins [from a different blockchain] must first be sent over. Meanwhile, the Bitcoiners who don’t opt-in never need to care what any sidechain is doing." Once on a sidechain, coins can change hands an unlimited number of times and in an unlimited number of new ways. Thus, BTC-owners can opt-in to new features or tradeoffs.
YouTube has allowed users to share videos pushing false conspiracy theories alleging interference with voting machines and election computer systems. Numerous false voter fraud conspiracy theories have circulated on social media since Election Day, including a couple claiming that the election’s technological infrastructure was hacked or tampered with. One theory falsely alleged that some kind of supercomputer named "Hammer" and a computer program called "Scorecard" were used to alter vote counts (and that footage shown on CNN last year proves it); The videos have racked up millions of views, and the platform has profited from some of them.
People don’t need to be concerned with what happens on another block with this tech, as it doesn’t affect them one bit . To the central planners out there, who are you to tell me what to put on a blockchain? Sidechains further emphasize this point.

— Liz Sly (@LizSly) November 13, 2020 Washington Post Beirut bureau chief covering Syria. US officials have been lying to Trump – and the American people – about the true number of US troops in Syria in order to deter him from withdrawing them, according to the outgoing Syria envoy. Trump thinks it’s 200 .
(The sidechain code itself will apparently be open-source. Their exact business remains mysterious, but is built around sidechains. He and a group of co-founders, including several core Bitcoin developers, headed by former Zero-Knowledge Systems CEO Austin Hill, have a launched a startup called Blockstream. are not acting purely out of technical benevolence. See Blockstream’s recent Reddit AMA.) According to Coindesk, they have already raised $15 million in an ongoing funding round, and added Reid Hoffman to their board.
