Proof-of-Stake vs. Proof-of-Work - What's the difference?
Decentralization is a distinguishing feature of most popular cryptocurrencies. However, the lack of a central authority in charge of transaction verification poses a problem: the network must validate transaction data to ensure that all information is correct and accurate.This determination is where the concepts of Proof-of-work and Proof-of-stake come into play.Proof-of-work and proof-of-stake are consensus mechanisms that allow blockchains to function securely. So that only authentic users can contribute new transactions to the blockchain, these consensus processes get used.Explaining Proof-of-WorkProof-of-work is a system in which computers compete to be the first to solve complex puzzles.Because the energy and resources required to finish the puzzle are often considered the digital counterpart of the real-world process of mining valuable metals from the earth, the process gets referred to as mining.Miners are authorized to generate a new block a grouping of transactions if they successfully solve the puzzle ahead of other miners. Then, the network of nodes will independently audit the existing ledger and this new block. If everything checks out, the new block is chained to the preceding block, producing a chronological transaction chain. The miner is paid in Bitcoins to compensate for providing their resources.Explaining Proof-of-StakeProof-of-stake minimizes the amount of computing labor required to authenticate blocks and transactions that ensure the security of the blockchain and, consequently, a cryptocurrency.Proof-of-stake alters coin owners machines to change the way blocks are added. The owners submit their coins as collateral in exchange for the ability to validate blocks and hence, be called validators.The block is then mined, or validated, by validators chosen at random. Instead of using a competition-based mechanism like Proof-of-work, this mechanism randomizes who gets to mine.Many validators validate blocks, and when a certain number of validators confirm that the block is correct, it is finalized and closed.A Breakdown of Proof-of-Stake vs. Proof-of-WorkThe most notable advantage of Proof-of-work is security and dependability. Because of the complexity of the mathematical equations required for verification, manipulating the system is practically impossible. The main downsides of Proof-of-work are its high energy consumption and slow speeds.Proof-of-stake, on the other hand, eliminates the need for complicated computations. So, in terms of energy efficiency, it outperforms Proof-of-work. Instead, those with most of the networks native currencies have the authority to validate transactions.The premise is that people who have a large stake in the system are less inclined to influence it. And if they do, their stake could be obliterated.When it comes to speed, Proof-of-stake outperforms Proof-of-work as well. For example, Ethereum, a Proof-of-work blockchain, can only execute 30 transactions per second at the most. Once the network has migrated to Proof-of-stake and has launched its shard chains, it hopes to be able to handle up to 100,000 transactions per second at peak times.ConclusionWhen it comes to security and decentralization, Proof-of-work still gets deemed superior. On the other hand, the Proof-of-stake is the winner when it comes to speed. There is not a single consensus mechanism that is superior to the others on all fronts in every situation.At Datacenters.com, our provider agnostic approach allows us to partner with hundreds of different data center operators, offering the widest selection of solutions possible. As a result of this, were uniquely positioned to know which hosting providersare accommodating of bitcoin miners and which arent.

Why Kubernetes on Bare Metal Is the Future
A lot has changed since the days when bare metal was considered a dirty word in the data center. Today, running Kubernetes on bare metal offers a variety of benefits that wouldnt have been possible even five years ago. But what changed? And what operational advantages does this union offer for cloud computing in 2022 and beyond? Lets get into it.A Brief HistoryTwo significant innovations are at the heart of the rising popularity of Kubernetes on bare metal infrastructure. The first catalyst was Linux containerization and the ability of developers to attach their application services to infrastructure at a more powerful API level. The second catalyst is the rising popularity of intelligent application services like machine learning, big data analytics, and high-performance computing. Again, bare metal was the natural fit here. Why? Because these emerging technologies demand infrastructure that can handle high-bandwidth and low latency workloads. In other words, they demand many compute resources and bare metal delivers.These recent innovations have enabled full exploitation of the underlying hardware, offering a more efficient and high-performance alternative to using a virtualization layer.Now lets get into some specific benefits of Kubernetes on bare metal.A Perfect Union - Realizing Kubernetes on Bare Metal InfrastructureWhile traditionally, the trend has been deploying Kubernetes in virtual machines, this deployment approach is becoming less popular. Virtual environments add additional costs (expensive licensing, among others) and complexity. Furthermore, organizations that want to leverage the entire stack of benefits and efficiency of cloud-native technology need to utilize fully optimized cloud infrastructure. This means switching over to bare metal.Opting for a simpler yet more performant match (Kubernetes on bare metal) paves the way for many exciting possibilities, which well discuss in this section.Bare Metal at The EdgeData is the lifeblood of companies in the modern world. This is especially true in industries like media and entertainment that harness vast amounts of data and need to drive fast interactions in real-time. This is where edge computing comes in. Edge computing is an IT architecture approach where client data is processed at the networks periphery, as close to the source as feasible. To accommodate this, edge deployments usually mean multiple sites.For several reasons, bare metal is quickly becoming the standard choice for multi-node clusters at the edge. Standardized integrations between bare metal and Kubernetes, like the Spectro Cloud Cluster API MAAS provider, have played a significant role here. However, comparison tests between Kubernetes bare metal vs. virtual machines (VMs) have also sealed the deal. A study by CenturyLink found that Kubernetes containers on bare metal achieved considerably lower latency (three times lower) than Kubernetes running on VMs.Kubernetes on Bare Metal Will Be the Default for 5GThe majority of telecom providers working on 5G are opting for Kubernetes on bare metal. This match is regarded as less resource-intensive than VMs while also allowing for quick deployment and greater ease when it comes to making changes. Low-latency and cost-effective operations are paramount for a fast and widespread 5G rollout.Why Should You Deploy Kubernetes on Bare Metal (Organizational Benefits)Beyond the role Kubernetes on bare metal is playing in some of the worlds cutting-edge technology projects, this match has many benefits for individual organizations.PerformanceBare metal environments enable direct access to CPU and RAM resources, which results in lower latency. For Kubernetes deployments, container-hosted applications can directly leverage hardware devices, maximizing resource utilization. Essentially, the union provides improved performance and is especially powerful for latency-sensitive or GPU-intensive workloads.Cost-EffectivenessIn terms of the total cost, Kubernetes on bare metal can work out significantly cheaper than VM alternatives for several reasons. First, at its most basic level, it eliminates the cost of virtualization software. You also dont have to pay to host an OS on both the bare metal server and the VM. Additionally, operational and labor costs are also lower because you dont have to pay for the management and maintenance of the virtualization layer. And lastly, with no hypervisor overhead, all of your servers resources go to running the workloads, resulting in reduced infrastructure costs.SecurityWith data breaches on the rise, security is understandably a top priority for organizations in 2022. Luckily, Kubernetes on bare metal addresses some key security vulnerabilities. Bare metal administrators have complete control over system configuration, vastly reducing the potential for cyber attacks. Additionally, bare metal environments eliminate the noisy neighbor effect inherent in VMs. This effect occurs when the VM uses the majority of available resources and therefore causes network performance issues for other tenants on the shared infrastructure.Configurations for Specific WorkloadsTypically, VM instances sport configurations designed to meet the needs of general workloads. While this might be fine for most scenarios, it does make things challenging when you need highly specific hardware configurations. Bare metal solves this by allowing for highly customizable configurations that can support a variety of demanding workloads.What Does the Future Look Like?Its not yet clear whether Kubernetes on bare metal will one day replace the need for virtual machines altogether. As it stands today, many organizations prefer to deploy Kubernetes on virtual machines for several reasons. Namely, they hold the isolation of virtual machine instances in high esteem or dont have the tools or experience to effectively manage Kubernetes on bare metal servers.However, the cloud-computing landscape is rapidly changing in response to the worlds ever-shifting technology demands. One significant area of change is the demand for direct access to hardware required for emerging applications, like machine learning algorithms. Equally important is the rise of 5G in the telecommunications space. And on an organizational level, Kubernetes on bare metal is also proving to add significant performance and cost benefits, further contributing to many companies making the move.While we cant predict the future, everything seems to be indicating that Kubernetes on bare metal will continue to dominate. Its quickly becoming the default API for infrastructure, providing the predominant abstract layer for infrastructure in the public cloud. As we look to the future, we expect to see far more use cases for Kubernetes on bare metal.

Are Biometrics Set to Replace Traditional Password Authentication?
The inception of computer password in 1960 by Fernando Corbat was a technological fete in its own right. With the ever-increasing security threats, businesses are looking for new and innovative authentication methods. Consumers demand quick, secure, and convenient processes. Biometric authentication can fulfill all three requirements. It can help businesses increase convenience and secure payments and logins. Can biometrics replace password authentication?What is biometric authentication?Biometric authenticationis an identity confirmation process that compares data for the cardholders characteristics to their biometric data. First, the physical and behavioral factors of the cardholder are captured and stored. A Biometric system uses this data to authenticate the cardholder.Password authentication relies on knowledge, what the user knows, and ownership, something the user has, such as a card or device. On the other hand, biometric authentication uses inherence, the users physical and behavioral attributes. Physiological factors include fingerprints, facial features, and iris patterns, while behavioral factors refer to keystroke dynamics, voice characteristics, or cursor movements.Why Biometric Authentication Could Replace Traditional PasswordsAlthough the password is still the most popular authentication method, more businesses are adopting biometrics. Users switch from old to new technologies to minimize the disadvantages or maximize the benefits. This human nature explains why biometrics are replacing traditional passwords and PINs.SecurityPassword authentication requires users to create, remember, save, share, and recreate their passwords regularly. These processes increase the risk of theft on transit or through phishing. Remember, passwords must be kept secret to be effective. Yet, employees share passwords for shared resources such as printers. This authentication method also exposes individuals to security risks. For example, anyone with a credit card and password can withdraw cash or go shopping. Biometric authentication addresses all these shortfalls. Unlike passwords, no one can steal, buy, share, or sell the users fingerprints, iris, facial features, or voice. More businesses are replacing passwords with fingerprint recognition because each fingerprint is unique and remains unchanged for a lifetime. Biometric authentication provides a more secure alternative to traditional passwords.ConvenienceToday, businesses and consumers use multiple devices, accounts, and platforms. Most people cannot remember several passwords. But using the same password across all your apps increases vulnerabilities. Biometric authentication doesnt require users to remember, check, or save anything. Using physical or behavioral attributes for authentication eliminates human error from the equation. Also, users cannot misplace their faces, voices, or fingerprints. Biometrics is more convenient than passwords.Future-proofApp and device security solutions such as multifactor authentication (MFA) and public key infrastructure (PKI) increasingly rely on biometrics instead of passwords. Advances in AI, sensor technology, and IoT will enable seamless biometric authentication. Unlike passwords, biometrics caters to current and future security needs in business. It evolves and improves with new and emerging technologies. Biometric authentication is future-proof.User-friendlyEmpowering employees through technology is crucial for success in todays digital age. Biometric is flexible enough to support the needs of all employees. Facial biometrics dont require additional actions to authenticate users, ideal for employees with disabilities. The visually impaired can benefit from behavioral biometrics. For example, voice verification only requires the user to repeat a word or a short sentence. Unlike passwords, you can customize biometrics to end-user or employee needs.Bottom LineBiometric authentication is a secure,convenient, and future-proof alternative to passwords. It is a user-friendly solution that can empower all end-users. More businesses are adopting biometrics to exploit its benefits and avoid inherently vulnerable passwords. Biometric is replacing traditional password authentication.
