10 A B S T R A C T This whitepaper presents a ground-breaking combination of Blockchain technology and payment ecosystem in Gemstone Industry, Infrastructure Development Sector and Software Industry. These industries have the potential to become the next asset class. In the digital age it should not be difficult to transact. This white paper addresses how Vertex (VRX intends to bridge the gap between the current ecosystem and the developing financial markets. Speed, transparency and costs associated with the cross-border payments are major challenges and obstacles in the Gemstone Industry, Software Industry and Infrastructure Development Sector. Traditional payment systems rely on centralized banks and credit institutions. These centralized financial institutions offer no transparency moreover demand a transaction fee from both parties doing business. Blockchain is emerging as the new system for recording and sharing information, including financial data. This decentralized technology offers transparency and makes it easy to transfer money or data across the world. There is no need to place trust in a central organization or institutions as the data is stored within a blockchain. The benefits of Blockchain in financial sector so exponential that the World Economic Forum predicts that 10% of GDP is going to be stored on the technology by Trading is a major aspect of human life. It is a necessity of everyday human life to exchange goods and services. 8

21 D I S C L A I M E R Cross-border money transfer and its drawbacks The payment industry represents one of the major issues in the businesses today. Payments are not just lucrative for the financial institutions, they are the anchor point in every deal. For banks, payment information becomes a source of information in terms of the client and further is an opportunity to generate leads to increase their business. Therefore, losing stakes in payment transactions will lead to massive loss for banks. Currently the payment industry across the world is in great upheaval as a resultof regulatory as well as political initiatives. Worth mentioning among them is the newsingle Euro Payments Area(SEPA), the new introduced regulation on interchange fessand revised Payment Service Directive (PSD2) which has come into effect from Alot of projects are trying to harmonize the payments across the globe. Globally, theemergence of smartphones is allowing the technology and telecommunicationentrants to patch this gap. Enterprises in every arena are squeezed between the needfor fresh investments and compliances and IT. For example, if Bank A wishes to send a transfer in euro to bank D in Germany, the workflow will be like: Bank A initiates a payment request to its correspondent bank, Bank B Bank B makes the adjustments and a message is sent to the correspondent bank, Bank C Bank C transfers the value via SEPA to Bank D Bank D transfers the amount of the beneficiary in euro 20

22 As shown in the payment flow chart, the bank charges fees for processing each transaction andthere by increasing the cost of all parties involved. SWIFT as a messaging service adds its transmitting costs. Moreover, as the ledgers are owned by individual banks, the SWIFT messages ensure that each debit and credit is communicated to another bank. This increases the number of messages supposed to be sent in the chain, with the increase in number of messages SWIFT fees also increases. The current process involves the following drawbacks: Since no two banks individually can agree on a transaction on their own, SWIFT comes into the picture as a guarantee. Swift charges banks for messaging information irrespective of the fact that the bank is the receiver or the sender of the message. Every cross-border payment has to go through certain banks in the chain who do activities like collating, netting payments. This increases the settlement time. A third party needs to be trusted with the powers of overwriting ledgers in a unified manner. Bank requirement of maintaining a certain level of liquidity in the accounts also comes intothe picture. The payment messages go through different services like Fedwire, SEPA and Swift When a cross border payment is initiated, the originator of the message is edited andpopulated by a bank account number. This raises security and data protection concerns inthe receiving bank. 21

23 BLOCKCHAIN INTEGRATION IS THE KEY TO SUCCESS Narrating the shortcomings of the cross-border payments process, blockchain as a distributedledger technology is gaining traction in banking and financial sector. Introduced in the year 2008,blockchain potential is now being realized by businesses across the world.blockchain as a distributed ledger presents itself as a technology which is accessible to everyone present in the network. The promising potential of the technology has increased interest of existing payment infrastructure such as Swift, provider of international payment transaction as well as regulator. Both technical and financial enterprises are looking forward to launch blockchain-based solutions to solve the issues arising in the cross-border payments. Institutions like banks across globe are in a situation where they need to support the existing payment mechanism while technologies like blockchain are being adopted and gaining market share. The prediction says that both, existing payment infrastructures as well as new technologies will co-exist as the payment system evolves. Payment eco-system needs a real-time evolution, any-to-any payments experience for customers; blockchain is going to play a fundamentally disruptive role in the evolution of realtime payments.the technology has the capability to enhance the payments system between multiple partiesacross the border, securely and with minimum transaction fees or operational friction. FACTORS TO BE UNDERSTOOD BEFORE BLOCKCHAIN ADOPTION Banks and financial institutions are setting up innovation labs to process Proof of Concept. Theseproofs of concepts will be able to harness the potential of distributed ledger technology knownas Blockchain. As per a recent study conducted by Accenture, 30% of the organizations are involved in conduction POCs along with different Fintech companies whereas 27% companies are formulating a strategy around the same. 22

24 While enterprises are on their way to adopt Blockchain as the DLT, here are a few critical factors that needs to be understood and addressed: 1. Standardization: Lack of calibration in formats. With globalization, we have to meet several global standards for messaging like Society for Worldwide Interbank Financial Telecommunication (SWIFT), Electronic Banking Internet Communication Standard (EBICS), ISO20022, ISO Expense reduction and time benefits: The payments across borders continue to lack trust and security. The expenses are more as it is difficult to assess charges and incurred through multiple correspondent banks. The identity of the banks involved is not always transparent between sender and receiving bank. 3. Data Security: There is a firm need to ensure that there are no data breaches and that the information has not been modified at any end of the chain. 4. Compliance and regulatory: Various regulations like AML, KYC and FATF needs to be followed to ensure that there is security in the process as well as to keep a tab on high risk payments. 5. Collaboration: Co-operation among payment service providers for an extensive global network. Benefits of Blockchain in Cross Border Payments 23

25 Vertex Coins in Infrastructure Development Sector The Infrastructure Development industry and the transactions in this industry are heavily dependent on intermediaries like brokers, title companies, escrows, attorneys and notaries. Vertex Coin has the potential to transform how the industry works with the help of Blockchain. Recording The Infrastructure Development Sector is completely dependent on government notaries or attorneys who maintain the trust factor. Blockchain recording will play an integral role where notaries aren't available. The recording can be done on the blockchain with the help of hash. These hashes then can be stored on blockchain to create an immutable record of the transaction. One doesn't need to pay the fees of these attorneys or government notaries as the transaction with Vertex Coins are going to be recorded on blockchain. Smart Workflow 24

26 When buying or investing in property, the process is often complex and elaborate, moreover results in loss of time and money. Whereas when transactions will be stored on blockchain, the speed of the workflow can be significantly improved, transactions will be visibly faster, and timelines will be reduced dramatically. It will also help in building trust as the transactions are updated in an immutable ledger. With Vertex Coins as you invest in properties across the world, the transaction is going to be quick and there will be no need to build trust as the process will be followed on a blockchain. Smart Escrow No industry is left aside from the plague of dependencies. Infrastructure Development Sector is heavily dependent of intermediaries like brokers and escrow agents who charge hefty fees to conduct transactions. Every transaction on Vertex coins will be done through smart contract. Based on blockchain technology, smart contracts are the digital alternatives to escrow agents. The transactions and contracts are automatically activated as the pre-conditions mentioned in the smart contract are met. Land Registry 25

27 The gemstone industry across globe will be reimagined, disrupted and improved with the help of blockchain technologies. With Vertex Coin we offer safer and more efficient ways to connect with partners in the gemstone business as well track and exchange gemstones. The ability to use blockchain technology to develop next level of supply chain the diamond industry will soon become a key element of success. Traceability Gemstone tracking in the entire industry ecosystem across the end-toend supply chain can be easily done through blockchain. All the stakeholders will be able to trace the origin of the gemstone. The tracking and tracing of finished gemstones from raw or even where the rough gemstone was mined from, provides high level of trust to the users. Vertex Coins is going to be the platform which will bring trust in the trade of gemstones with the help of blockchain. The smart contracts and hash generated records the complete chain of custody of the gemstones from their origin to point of sale. Flexibility: Transactions in Gemstones can be made quick and secure through blockchain and cryptocurrency. With virtual payment applications transactions can be made quickly through devices and in instant. 27

28 Consumer Payments: Blockchain has revolutionized the transaction process by improving the speed, cost, and security of international payments. The use of cryptocurrencies could be the next big step in the retail industry where consumers could by their daily needs through Bitcoin or Ethereum.Cryptocurrency offers real advantages for both cross-border payments and micro-payments. Blockchain technology could be easily implemented in the traditional payment system making it fast and secure for both the parties. However, it is a fact that these benefits are more applicable in the context of businesses where the size of payments is huge. Blockchain has the potential to streamline the consumer payments and make the multi-currency settlements easy. Product Authenticity Blockchain is the new concept for data management. It is a distributed ledger (database) with a new way how the data is stored, secured and synchronized between multiple parties. It allows the data to be controlled by several equal parties without central authority. It eliminates possibility of fraud by one/single authority, provides the right level of transparency and immutability of the 28

29 Any attempt to falsify data will be detected and rejected by the members of Blockchain network, who maintain the correct version of the data. The manufacturers can add unique identifier to every produced item and update the entries into the blockchain. Vertex Coins use the Blockchain technology to store records or database of the produced products, which can be accessed by suppliers and consumers to check the authenticity of the products. Vertex Coins in Software The software industries is one such industry which mostly involve cross border payments between B2B and B2C businesses. Vertex Coin standalone is potent to make such payments easy, fast and secure with no Brokers involved. 29
