“Arbiter” may sound like an absolute authority, but they’re going to participate in only one special feature in Obyte: contracts with arbitration. Anyone can join as an arbiter today and earn fees from it, without coding or complex steps. in Obyte is a type of smart contract in which the parties can write their own terms and lock the funds until conditions are met. A contract with arbitration In case of a dispute, they can resort to an expert arbiter. To the final users, the process could be comparable to any dispute resolution system from online marketplaces like or —but easier and faster. eBay Amazon In centralized companies, such as the ones mentioned above, their team has the authority to determine the allocation of funds or goods in the event of a dispute. They have total control of their platforms and the funds on them. In contracts with arbitration, that role is for an expert arbiter selected by both parties before signing the contract. How Does a Contract With Arbitration Work? The term “smart contract” could imply programming knowledge, but not this time. Anyone with an Obyte wallet can with arbitration by only following a simple path. In the first place, both parties need to have Obyte’s native wallet and pair them with each other. prepare a contract That’s easy: just send a pairing invitation to a new device **(Chat Tab – Add a new device).
\ Next, one of the parties offers a contract with arbitration to the other. As an example of Alice and Bob: For a contract with arbitration, they need to select an expert and reliable arbiter from the recently launched Obyte’s . Alice and Bob discuss their contract and terms externally or in the built-in encrypted chat in the wallet. ArbStore , by clicking on the other party’s address. If the other party accepts it, the involved funds (in USDC, GBYTEs, GBB, or any other token) will be locked in a smart contract until the terms of the contract are met. One of the parties (Alice or Bob) offers a contract with arbitration through the chat If the buyer is happy with the goods/services provided by the supplier, In this case, the arbiter is not involved. the buyer releases the funds from the smart contract in favor of the supplier. If one of the parties fails to fulfill their obligations, The arbiter ultimately decides who gets the funds. However, they can also be reported to the ArbStore moderators if they misbehave. the other party can open a dispute and call an arbiter to resolve the issue. The arbiter doesn’t need programming knowledge either. Just enough knowledge in their area (legal, IT, real estate, collectibles, domains, export/import, etc.), some time to solve the case, and a personal . Obyte wallet What Is the Process Like For an Arbiter? After the claim is sent by one of the involved parties (buyer or seller), the arbiter receives a message in their wallet from the ArbStore Bot. That message includes links to check the written contract (not in a programming language, it’s a legal contract like any other) and to set the desired fee to solve the case. the arbiter should check the text carefully, and decide if it is a contract type they indicated on their profile they can resolve disputes in. If it is not, they can refuse to take the case and communicate it to the plaintiff in chat. At this point, , or if they have to resolve the dispute with the other party by themselves. The plaintiff can contact the ArbStore moderators if they disagree with the arbiter’s qualification of the contract If the arbiter takes it, they should wait until the claimant pays for the requested fee. Then, the arbiter would start talking to both parties and gathering evidence to make their last decision. Finally, who receives the funds is just a matter of choosing between two buttons: Plaintiff or Respondent. As a last resort, the plaintiff can report the arbiter to the ArbStore moderators. All of this is always done inside the wallet chat, without any other external middlemen. However, they won’t be able to recover 100% of the funds. That’s why some basic requirements are recommended to become an arbiter, even if anyone can join the platform. How to Become an Arbiter? In case of a legal dispute on the terms of the agreement, a professional lawyer is the best option for an arbiter, but any other professional is welcome as well –in case the parties are disputing technical rather than legal matters. There are no applications, only registrations. Nevertheless, the ArbStore moderators have the right to unlist the arbiters that don't add value to the store. And it’s important to note that becoming an arbiter has one small starting fee. The fee goes for a , which is available through the wallet. Users of contracts with arbitration are looking for reliable experts, so, real-name attestation process arbiters must show they can be trusted with someone else's money. That’s why revealing the arbiter’s verified real name to the ArbStore (and its users) is strongly recommended. Even if arbiters don’t reveal their real name and stay anonymous to the ArbStore and its users, real name attestation is still required to prevent multiple arbiter listings by the same real person. Of course, a verified real name doesn’t guarantee the arbiter’s integrity and expertise, but for many users, that would be a minimum necessary (but not sufficient) requirement. It can be done with the services of Veriff (available worldwide), and the fee is $8 per attempt. If arbiters are attesting themselves for the first time, Obyte will refund them $8 afterward. will guide registrants through the attestation process. A chatbot Other than this, just follow the instructions of the ArbStore chatbot in the wallet to sign up. It’ll be necessary for arbiters to share a detailed bio on the platform, including professional background, dispute resolution process, preferred topics, approximate fees, spoken languages, and how they are protecting their wallet. How Much Can an Arbiter Earn? That depends entirely on the arbiter pricing, how often the arbiter is selected in contracts, and the funds involved in the contracts. For example, an arbiter Carol can set 5% as her dispute resolution fee for Contract X, which involves $100,000 in USDC. That would be $5,000 for Carol (the arbiter). She decided to set that percentage because it was a complex corporate contract, but she could take “simpler” contracts as well, with a better percentage for the plaintiff. For example, let’s say she agreed to solve Contract Y, a one-page contract that only involves $1,000 between individual parties. This time, Carol decided to offer a 2% fee, and her gains would be $20 after resolution. However, it’s likely that most arbiters end up setting a price that sounds like “2%, min $50, max $1,000” to be adequately paid for their time. One last important bit: the arbiter won’t get paid until they solve the dispute. The fee paid by the claimant is held by the ArbStore until the ultimate decision is made. Arbiters must and make proper backups. protect their wallets If they lose access to their wallets, the disputed funds of others could be locked there forever. As Uncle Ben said: "With great power comes great responsibility." Now, if you’re ready to step in, gain valuable experience for your career, and earn some cryptos in the process, the ArbStore is waiting for you. !

There are many concerns when it comes to investing in cryptocurrencies. One of the biggest concerns is security. With all the hacks that have happened, it's normal that people are worried about cybercrimes. Theft, fraud, and other crimes are unfortunately common occurrences in the cryptocurrency world. In order to themselves and their investment, users must be aware of the risks and take precautions. protect Many cryptocurrency projects are working on ways to increase investors' protection. Here are a few of them who coalesce around an ecosystem managed by Seek Token who specialize in hunting crypto scammers and appear on “National Geographic’s “trafficked” show shortly, exposing scammers live on air. #1 Poodl Token is a BEP-20 cryptocurrency with a deflationary strategy to appeal to investors. The initiative merges 3D NFTs and augmented reality (AR) technology, merging into gaming and e-commerce utilities. Regarding security, the team explains that the project has three main pillars: verified channels, security audit, and locked liquidity. Poodltoken The project has a “verified” badge on CoinMarketCap, Twitter, OpenSea, and Telegram. The team is applying to receive this status on all the social platforms it employs. Moreover, Solidity Finance completed a smart contract audit on Poodltoken, granting the project a security certification. KYC (Know Your Customer). POODL Token is fully KYCd through SEEK Token, backed by corporate veriff.com, and is tasked with outing bad actors in the space. Furthermore, the team locked the POODL/wBNB pool on Unicrypt for five years. This operation generally serves as a way to prove the dedication of the developers to the crypto project they launched. #2 Infinity Lotto2 It is the goal of to introduce a cryptocurrency project that is lucrative, secure, and tightly knit. For investors, the team hopes to provide additional revenue via awards and a possible InfinityLotto jackpot. InfinityLotto The creators clarified that all investors would be able to participate in the drawing regardless of their financial situation. Using the BNB Chain as its backbone, the initiative rewards its community in BUSD and staking options. Again SEEK KYCd. Its founders believe security and protection are among InfinityLotto's top priorities. The project uses all available technology to encrypt all personal information. This operation wants to guarantee that users’ data is secure while moving into the crypto industry. #3 Crolon Mars There will be no gas fees to transfer coins using , another cryptocurrency project with a security audit by Seek. To recoup its costs, the proposal imposes a charge on all transactions. Crolon Mars also intends to rely on advertising revenue from its Play-to-Earn (P2E) games to fund its operations. Crolon Mars CLMRS, the project's native token on the CRONOS chain, backed by crypto.com, is available to buy and invest in their soon-to-appear Metaverse, which will be a gateway into other metaverse platforms (the Multiverse) In order to tempt new gamers and investors, the team introduced 3d NFTs to the project which will feature as avatars in the metaverse. Intending to leverage the industry expansion, the initiative set up a virtual NFT marketplace within its network. SEEK Token also performed a full KYC service for CRLMS. This service is quickly becoming known as the “gold standard” of KYCs due to its stringency. #4 Cure Chain is a blockchain-based healthcare platform that enables patients and doctors to share medical data securely. The platform includes several features that make it easy for users to manage their health information. CureChain Among these functionalities, one can mention a medical data marketplace, a personal health record (PHR) system, and a secure messaging service. CureChain aims to help patients take control of their health data and make better-informed decisions about their care. The CureChain platform’s idea came from a team of experienced healthcare professionals and technologists. The team wants to provide patients with a simple way to access their medical data. This opportunity, in the original idea of the founders, may help anyone make better decisions about their health. CureChain is a rapidly developing start-up that investors have been observing for a while. #5 Lakeview Meta Rather than competing with other projects, wishes to contribute to the expansion of the overall investor confidence. The team sees this scenario as a win-win situation for everyone involved in this market. LVM has been ultra-focused on partnerships before launching its own token, solidifying and cementing lasting partnerships with many legitimate projects, such as the ones mentioned here. Lakeview Meta The project has shared intuitive instructions to move around its metaverse. Anyone can walk, run, or drive in this digital dimension. The project even lets anyone teleport around and join treasure hunts. Like many metaverse-based projects, Lakeview Meta launched a token on the market with several digital properties. The real estate market may have a new chance to grow in the metaverse. These projects wish to be ready to profit from this trend. More Information About Seek As mentioned above, audited all the projects above to certify their security. These initiatives are all part of Seek’s ecosystem of trusted projects. Seek The Seek team members describe themselves as an organization dedicated to erasing corruption and deception in the cryptocurrency industry. Team members feel crypto has been on a downward spiral for some time now, at least in terms of security. Investors have enjoyed the increased success of this business, while fraudsters have found new ways to get money. Seek will appear on “Trafficked” during the Summer on Nat Geo TV. The project aims to hunt crypto scammers and improve the security of this business. Final Thoughts Many of the projects in this article have recently attended the “Crypto Legends AMA” event. Many crypto initiatives are joining forces to send positive messages to their communities and investors. Many people are not aware of the dangers of scammers when it comes to crypto. There are many ways that scammers can take advantage of people, and it is essential to be aware of them. Independent audits and team cooperation are two aspects that can increase the security of investing in cryptocurrencies. With increasing regulation coming to this market, traders hope the chances of falling for a scam will gradually decrease.

Having explored how to implement an authentication system in Next.js 14 with NextAuth.js(Auth.js) in the first part of this blog, it is crucial to take the next step to ensure the validity of user information: email validation. This process is not only an additional step in the security of our application, but an essential component to ensure that interactions between the user and the platform are legitimate and secure. In this second part, we will focus on integrating email validation by sending emails, using Resend for sending emails, and React Email to create attractive and functional email templates. Initial Configuration Make sure your project already has the authentication system described in the first part of the blog implemented. This includes having Next.js 14 and NextAuth configured correctly. https://hackernoon.com/how-to-implement-authentication-in-nextjs-14-with-nextauthjs-shadcnui-react-hook-form-and-zod?embedable=true Resend and Ract Email Integration in Next.js Setting Up Install the dependencies needed in the project. This time we’ll use you can use the package manager of your choice. pnpm pnpm add resend react-email @react-email/components : to send emails. Resend : to create beautiful emails using React and TypeScript. React Email 2. Create the following structure for the project: ...

... Creating Email Templates With React Email React Email allows you to create email templates using JSX, which facilitates the creation of attractive and consistent emails with your brand. Let’s create a basic email template as a React component. In this case, we will create the template that will be sent for the user to confirm their email. : emails/verification-template.tsx // Import React and necessary components from @react-email/components
import * as React from 'react';
import { Body, Button, Container, Head, Hr, Html, Img, Preview, Section, Text } from '@react-email/components';

import { getBaseUrl } from '@/utils';

// Obtain the base URL using the imported function
const baseUrl = getBaseUrl();

// Define the properties expected by the VerificationTemplate component
interface VerificationTemplateProps {
    username: string;
    emailVerificationToken: string;
}

// Define the VerificationTemplate component that takes the defined properties
export const VerificationTemplate = ({ username, emailVerificationToken }: VerificationTemplateProps) => (
    <Html>
        <Head />
        <Preview>Preview text that appears in the email client before opening the email.</Preview>
        <Body style={main}>
            <Container style={container}>
                <Img
                    src='my-logo.png'
                    alt='My SaaS'
                    style={logo}
                />
                <Text style={title}>Hi {username}!</Text>
                <Text style={title}>Welcome to Starter Kit for building a SaaS</Text>
                <Text style={paragraph}>Please verify your email, with the link below:</Text>
                <Section style={btnContainer}>
                    {/* Button that takes the user to the verification link */}
                    <Button
                        style={button}
                        href={`${baseUrl}/auth/verify-email?token=${emailVerificationToken}`}
                    >
                        Click here to verify
                    </Button>
                </Section>
                <Hr style={hr} />
                <Text style={footer}>Something in the footer.</Text>
            </Container>
        </Body>
    </Html>
);

// Styles applied to different parts of the email for customization
const main = {
    backgroundColor: '#020817',
    color: '#ffffff',
    fontFamily: '-apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Oxygen-Sans, Ubuntu, Cantarell, "Helvetica Neue", sans-serif',
};

const container = {
    margin: '0 auto',
    padding: '20px 0 48px',
};

... This component creates an HTML email template that includes styles and dynamic content. Properties are defined to receive y . These properties are used to customize the email for the user and generate the verification link. username emailVerificationToken To validate and test the template React Email provides a command to locally run a server that will expose the templates we have created inside the emails folder. We create the script in the to run the server. package.json {
  "scripts": {
    "dev": "email dev"
  }
} 2. We execute the script and this will run the server on ; we will see a screen like the following with all the templates created. localhost In our case, we have only one template. As you can see below, we have a preview of the email that will be sent to the user. Sending Emails With Resend Create a . Resend account Create a new . API KEY Add the to file. API KEY .env ...
# resend
RESEND_API_KEY="re_jYiFaXXXXXXXXXXXXXXXXXXX" 4. To create the functionality of sending emails, we could create endpoints inside the folder and make requests, however, on this occasion we will do it by taking advantage of the server actions potential. api/ http : actions/email-actions.ts 'use server'

import React from 'react'
import { Resend } from 'resend'

// Creates an instance of Resend using the API KEY
const resend = new Resend(process.env.RESEND_API_KEY)

// Defines the data structure for an email.
interface Email {
    to: string[] // An array of email addresses to which to send the email.
    subject: string // The subject of the email.
    react: React.ReactElement // The body of the email as a React element.
}

export const sendEmail = async (payload: Email) => {
    const { error } = await resend.emails.send({
        from: 'My SaaS <onboarding@resend.dev>', // Defines the sender's address.
        ...payload, // Expands the contents of 'payload' to include 'to', 'subject', and 'react'.
    })

    if (error) {
        console.error('Error sending email', error)
        return null
    }

    console.log('Email sent successfully')
    return true
} Note: To test in free development, you have to use as the sender the email “onboarding@resend.dev”, otherwise, you would have to add a custom domain. 5. Send the email when registering a new user. : actions/auth-actions.ts ...

import { sendEmail } from './email-actions'

import VerificationTemplate from '../../emails/verification-template'

// Import a utility function to generate a secure token.
import { generateSecureToken } from '@/utils'

export async function registerUser(user: Partial<User>) {
 try {
  // Creates a new user in the database with the provided data.
  // Passwords are hashed using bcrypt for security.
  const createdUser = await prisma.user.create({
   data: {
    ...user,
    password: await bcrypt.hash(user.password as string, 10),
   } as User,
  })

  // Generates a secure token to be used for email verification.
  const emailVerificationToken = generateSecureToken()

  // Updates the newly created user with the email verification token.
  await prisma.user.update({
   where: {
    id: createdUser.id,
   },
   data: {
    emailVerificationToken,
   },
  })

  // Sends a verification email to the new user using the sendEmail function.
  await sendEmail({
   to: ['your Resend registered email', createdUser.email],
   subject: 'Verify your email address',
   react: React.createElement(VerificationTemplate, { username: createdUser.username, emailVerificationToken }),
  })

  return createdUser
 } catch (error) {
  console.log(error)
  if (error instanceof Prisma.PrismaClientKnownRequestError) {
   if (error.code === 'P2002') {
    // Returns a custom error message if the email already exists in the database.
    return { error: 'Email already exists.' }
   }
  }

  return { error: 'An unexpected error occurred.' }
 }
} Once the user is created and the verification token is generated, the function sends an email to the new user. This email is constructed using the React component, personalized with the user's name and verification token. This step is crucial for verifying the user's email address as valid and controlled by the user. VerificationTemplate Page to Validate the Token Once the email is sent to the user, this will have a link that will take him back to the site. To validate the email, for this, we need to create the page. : (primary)/auth/verify-email/page.tsx /* 
  All imports
*/

// Defines the prop types for the VerifyEmailPage component.
interface VerifyEmailPageProps {
 searchParams: { [key: string]: string | string[] | undefined }
}

export default async function VerifyEmailPage({ searchParams }: VerifyEmailPageProps) {
 let message = 'Verifying email...'
 let verified = false 
 if (searchParams.token) { // Checks if a verification token is provided in the URL.
  // Attempts to find a user in the database with the provided email verification token.
  const user = await prisma.user.findUnique({
   where: {
    emailVerificationToken: searchParams.token as string,
   },
  })

  // Conditionally updates the message and verified status based on the user lookup.
  if (!user) {
   message = 'User not found. Check your email for the verification link.'
  } else {
   // If the user is found, updates the user record to mark the email as verified.
   await prisma.user.update({
    where: {
     emailVerificationToken: searchParams.token as string,
    },
    data: {
     emailVerified: true,
     emailVerificationToken: null, // Clears the verification token.
    },
   })

   message = `Email verified! ${user.email}`
   verified = true // Sets the verified status to true.
  }
 } else {
  // Updates the message if no verification token is found.
  message = 'No email verification token found. Check your email.'
 }

 return (
  <div className='grid place-content-center py-40'>
   <Card className='max-w-sm text-center'>
    <CardHeader>
     <CardTitle>Email Verification</CardTitle>
    </CardHeader>
    <CardContent>
     <div className='w-full grid place-content-center py-4'>
      {verified ? <EmailCheckIcon size={56} /> : <EmailWarningIcon size={56} />}
     </div>
     <p className='text-lg text-muted-foreground' style={{ textWrap: 'balance' }}>
      {message}
     </p>
    </CardContent>
    <CardFooter>
     {verified && (
      // Displays a sign-in link if the email is successfully verified.
      <Link href={'/auth/signin'} className='bg-primary text-white text-sm font-medium hover:bg-primary/90 h-10 px-4 py-2 rounded-lg w-full text-center'>
       Sign in
      </Link>
     )}
    </CardFooter>
   </Card>
  </div>
 )
} After successfully validating the user’s email, we will see the following message. Now, we will implement a last validation for when the user wants to log in and has not yet verified his email. : components/auth/sigin-form.tsx ...

 async function onSubmit(values: InputType) {
  try {
   setIsLoading(true)

   const response = await signIn('credentials', {
    redirect: false,
    email: values.email,
    password: values.password,
   })
   if (!response?.ok) {
// if the email is not verified we will show a message to the user.
    if (response?.error === 'EmailNotVerified') {
     toast({
      title: 'Please, verify your email first.',
      variant: 'warning',
     })

     return
    }

    toast({
     title: 'Something went wrong!',
     description: response?.error,
     variant: 'destructive',
    })
    return
   }

   toast({
    title: 'Welcome back! ',
    description: 'Redirecting you to your dashboard!',
   })

   router.push(callbackUrl ? callbackUrl : '/')
  } catch (error) {
   console.log({ error })
   toast({
    title: 'Something went wrong!',
    description: "We couldn't create your account. Please try again later!",
    variant: 'destructive',
   })
  } finally {
   setIsLoading(false)
  }
 }

... That’s it! 🎉 The user will be able to validate his email and finish his registration in our application. 🧑‍💻 Repo here Conclusion We already know how to create and send emails using React Email and Resend.

What are ZK Proofs and How are They the Future of Verifiability

If the complex and costly hardware required for traditional mining has been a deterrent for you, or if you’re weary of the relentless grind to boost transaction volumes just to earn fees, now there’s a refreshing alternative. Discover the brand-new mobile mining experience that ‘ ’ provides, where your smartphone becomes your portal to a rewarding ‘verify to earn’ journey. Massive Introduction We’re thrilled to introduce , our innovative mobile mining app, poised for launch alongside the upcoming at beginning of April. As the first project in the blockchain sector to leverage ‘ZKVM+DePIN+AI’ technology, Ola is at the forefront, pioneering a new, fair, open and user-centric approach to blockchain interaction with this initiative, Massive. Massive Ola Testnet Alpha Massive simplifies the blockchain experience by removing the need for expensive hardware or technical expertise. Our vision for Massive is direct and clear: to democratize web3 access by providing a platform where anyone with a smartphone can participate and earn rewards through simple verification tasks. Our commitment with Massive is to lower the entry barriers to blockchain technology, making it accessible and equitable for all users. By introducing the ‘verify to earn’ concept, we’re not only changing how people mine; we’re also transforming their role within the blockchain ecosystem from passive observers to active participants. Massive, as a crucial part of Ola’s development strategy, . Ola is set to open applications for invitation codes on March 18th, releasing the first set of 1,000 codes for node registration. This initial offering is limited to 1,000 nodes, with registrations being accepted on a first-come, first-served basis. Additionally, the first 1,000 nodes will have the privilege of generating invitation codes, allowing them to invite newcomers with these codes to earn rewards. plans to allocate about 10% of Ola’s token to verifiers & miners, with an initial 1% being used for Ola Testnet Alpha Join us as we embark on this exciting journey to make blockchain technology intuitive, inclusive, and rewarding for everyone, everywhere. Background The industry has tirelessly explored various strategies to engage traditional users (those outside the web3 ecosystem), including gaming, infrastructure, and incentivizing through airdrops. Notable efforts like StepN’s ‘move to earn’ and Starkware’s airdrops for non-Web3 developers momentarily captured high interest, hinting at potential breakthroughs. However, their inability to sustain long-term momentum and impact highlighted the critical need for innovative, enduring approaches that truly resonate with and retain users in the blockchain realm. “We recognized the need for a standout feature that resonates deeply with users; thus, Massive was conceived as our bold solution to this industry challenge,” - Simon Chen, co-founder and CEO of Ola Ola’s mission with Massive is to catalyze the widespread adoption of web3, advocating for a decentralized and fair digital ecosystem. By introducing the ‘verify to earn’ concept, where anyone with a smartphone can participate in mining, Massive aims to significantly lower these barriers. Additionally, users can engage with multiple projects over time on their smartphones, enhancing the longevity and diversity of their participation. This approach will foster a more inclusive environment, encouraging a broader demographic to engage with, understand, and contribute to the web3 space, while receiving long-term rewards. The introduction of Massive is a strategic move toward making blockchain more accessible and engaging for the general public, thus infusing the industry with new participants and fresh perspectives. Through this initiative, Ola envisions transforming mere observers into active contributors, nurturing a dynamic and sustainable blockchain community. Massive: Fair Opportunities for All In the realm of traditional mining, such as the Proof of Work (POW) mining mechanism, the requirement for costly hardware presents a significant barrier to ordinary users. When developing Massive, Ola focused on reducing entry barriers, enhancing user experience, and increasing user rewards, all while guaranteeing utmost fairness for EVERY user. Massive is a decentralized authentication network composed of various mobile elements. In terms of user-friendliness, Massive boasts several key features: User Access Threshold: : Users can easily access Massive by simply downloading the necessary app and wallet on their smartphones. Low Entry Barrier : Massive supports a broad range of mobile models, compatible with both Android and iOS (coming soon) systems. Minimal Device Requirements User Rewards (10% of Ola’s tokens): : Users receive rewards by completing verification tasks, providing a straightforward way to earn. Verify to Earn : In addition to earning verification rewards, users can also gain additional returns by inviting newcomers with a referral code and through staking activities. Multiple Reward Streams User Experience: : Users can join or leave the network at their convenience, offering the flexibility to suit individual needs. Flexible Access and Exit : Without the need for complex operations or maintaining high transaction volumes, Massive simplifies user participation. Ease of Use : Compared to distributing funds across multiple addresses, using a smartphone to participate presents a lower barrier for the average user. User-Friendly Enhanced Network Security and Intelligence: : Massive harnesses AI+zk technology to elevate network security and intelligence, utilizing AI for nuanced analysis of node service statuses. This results in refined task distribution and heightened network efficiency. AI + ZK Integration Platform Fairness and Sustainability: : Massive ensures fairness for all users, where everyone’s time and contributions are equally valued. Fair : Users can engage with multiple projects over time on their smartphones, enhancing the longevity and diversity of their participation. Sustainable Massive Changes the Game: Say Hi to Your New Web Roles At Massive, your role is fundamentally transformed. Gone are the days of having to “slave away” by artificially boosting transaction volumes and amounts to earn incentives. Now, all you need is a standard smartphone to connect. By simply staying active and verifying, you can consistently earn rewards. But your role evolves further; once you connect as an Ola node, you become an essential part of maintaining the network’s security. You might have felt the imbalance before, as web3 whales could distribute their funds across multiple addresses to amplify their earnings, a feat not so easily replicated by purchasing multiple smartphones. Hence, Massive levels the playing field, offering a balanced opportunity for both whales and retailers. On the Massive platform, everyone participates and contributes in the same manner, ensuring fairness. This approach incentivizes a broader spectrum of users to engage with the web3 ecosystem, lowering entry barriers and bolstering decentralization and equity within the system. With Massive, every participant has the chance to earn rewards fairly, fostering wider participation and a healthier network. Distinct from other staking or mining models where more staking could mean more chances to validate, Massive champions decentralization and equity. Every node stakes an equal value, and by merely staying online and completing verification tasks, rewards can be earned. Time is valued equally across all participants, ensuring that mining on Massive is inherently fair. This paradigm encourages broader and more equitable user engagement, reinforcing the network’s integrity and community inclusiveness. Looking Ahead: Shaping the Future of Blockchain and Web3 Mobile Experiences with ZK Technology As we gaze into the future, our expectations for the Massive are set even higher: Firstly, as a purely decentralized ZK verification network, Massive is poised to accelerate the modularization of blockchain design. Secondly, with an increasing influx of new users joining the blockchain, we anticipate the emergence of genuine Web3 mobile technology. This evolution promises not only to propel the advancement of blockchain technology and invigorate the ecosystem but also to offer users a more equitable, open, and convenient digital experience. Collectively, these efforts aim to facilitate the widespread adoption and development of blockchain technology, steering the industry toward a more prosperous future. Join the Venture! Ola is tackling blockchain’s biggest hurdles: fairness and accessibility, with its gamechanging ‘Massive’ app, leveraging “ZKVM+DePin+AI” technology. Massive simplify blockchain interactions with a ‘verify to earn’ model, opening the digital door for anyone with a smartphone. 🗓️ March 18 marks the launch of Ola’s first 1,000 node registration codes, with mining, new features, and greater rewards soon to follow. Early nodes gain the advantage of creating invite codes for collaborative reward earning. Join us on this venture and be among the first to benefit!

Strengthening Fairness to Progressive Runs B. Proofs from Section 4.1 C. Proofs for Section 5 D. Proofs for Section 5.3 E. Proofs for Section 6 B PROOFS FROM SECTION 4.1 Intuitively, the edge in (1) spawns the initial thread, the edges in (2) remove a thread with csnumber 0 when it becomes active for the first time and the edges in (3) convert it to a balloon, the edges in (4) apply the spawns during the 푗th segment of a thread by transferring them from the balloon to the regular places, the edges in (5) and (6) finalize this application process with the edges in (6) handling the special case of the 퐾th segment of a thread, the edges in (7) burst balloons containing no more spawns, and the edges in (8) initialize the application of spawns for a thread with cs-number ≥ 1 that is already being represented by a balloon. Lemma B.1. The DCPS A has an infinite, progressive, K-context switch bounded run iff the VASSB V has an infinite progressive run. Proof. For the only if direction let p be an infinite, progressive, K-context switch bounded run of A. We want to decompose p into parts corresponding to a single thread each. To do this we look at the continuous segments of p where a thread is active, starting from the first configuration with an active thread and ending each segment at a configuration with no active thread, upon which a new segment begins at the very next configuration. We can now group segments together into executions of single threads: • Start with the earliest not yet grouped segment where the active thread has context switch number 0. Note the local configuration that gets added to the bag at the end of this segment. • Take the very next ungrouped segment in p where the active thread at the beginning matches the previously noted local configuration. Again, note the local configuration that gets added to the bag at the end of this segment. • Repeat the previous step until an empty stack occurs. The constructed run of V is also sound: For each segment of p it has a sequence of transitions that make the same state change as that segment, and also apply the same spawns. The latter is due to initially choosing the contents during the creation of a balloon correctly. A token representing the initial thread is also created in the beginning of the run. Since the transitions from one segment to the next require the same resumption rules Δr as in p (see edges (2) and (8)) these are also possible in V. For the if direction we do a very similar construction, but backwards. Starting with an infinite progressive run of V from c0, we decompose it into segments that end in a state in G. Afterwards we group those segments together by matching the local balloon configurations in the same way we did for local thread configurations before. Then by construction of Lt we know that there is a thread execution of type t that makes the same spawns in each segment as the group of one balloon does. Those executions will all terminate after K context switches, guaranteeing progressiveness, and we can interleave them in the same way as the balloon segments to form an infinite progressive run of A.
