Tokenization v2

To increase the security of mobile payments, many payment schemes nowadays apply a technology called tokenization. Tokenization is the process of replacing an existing payment card number with a surrogate value (token). This token is used during a payment transaction, keeping the original card number safe. A Token Service Provider (TSP) is an entity within the payments ecosystem that generates and manages tokens. The TSP maps the original card number with the payment tokens and stores this safely in a token vault. Often these tokens can only be used in a specific domain such as a merchant’s online website or channel, limiting the risk even further. A TSP manages the entire lifecycle of payment credentials including: Token Requestor Authorization Host 1. Tokenization: Replaces the PAN with a payment token. 2. De-tokenization: Converts the token back to the PAN using the token vault. 3. Token vault: Establishes and maintains the payment token to PAN mapping. 4. Domain management: Adds additional security by restricting tokens to be used within specific (retail) channels or domains. 5. Identification and verification: Ensures that the payment token is replacing a PAN that was legitimately used by the token requestor. 6. Clearing and settlement: Ad-hoc de-tokenization during clearing and settlement process. Issuers, acquirers and merchants that wish to offer mobile and/or digital payments to customers can become a TSP. Becoming your own TSP gives full control over the tokenization process: creation, storage, issuance and management. By having your own TSP, you are in full control of digital payments by issuing tokens directly without third party intervention. By using a third party TSP from the payment schemes, issuers need to integrate with each payment scheme. Benefits of having you own TSP: 1. Reduce long term costs: no additional TSP fees from the payment schemes. 2. On-us transactions: save on transaction fees when you are the issuing as well as the acquiring bank. 3. Banks retain their privacy because data and roadmaps do not have to be shared with the schemes. 4. Keep track of customer payment behavior to gain valuable insight and be able to offer personalized services. 5. Expand to multiple use cases.

Blockchain is a distributed database that maintains a growing list of transaction records organized in blocks. Each block contains a cryptographic hash of the previous block, transaction data, and a timestamp. This creates a permanent, unalterable record of transactions that is distributed across a peer-to-peer network of nodes. Blockchain technology enables a decentralized system of recordkeeping that does not require a central authority and allows digital transactions to be validated and recorded in a transparent yet secure manner. It has applications in finance, healthcare, supply chain management, and more.

The adoption of blockchain technology continues to accelerate across a wide array of industries, yet many of our clients are confused about how to deploy these solutions within their environment. EY has developed a blockchain stack that fits within the existing enterprise infrastructure, project and system development life cycle approaches that are customized to the new technology, and development frameworks to streamline our deployment.

Bitcoin is a decentralized electronic cash system using peer-to-peer networking to enable payments between parties without relying on mutual trust. It was first described in a paper by Satoshi Nakamoto (widely presumed to be a pseudonym) in 2008. Payments are made in bitcoins (BTC's), which are digital coins issued and transferred by the Bitcoin network.

This document discusses Ethereum 2.0 and its goals of improving decentralization, scalability, and energy efficiency over Ethereum 1.0. It outlines the key components of Ethereum 2.0 including using proof of stake instead of proof of work, implementing sharding to partition the blockchain into multiple shards to improve scalability, and transitioning to a new virtual machine. It provides timelines for rolling out these changes and demos running an Ethereum 2.0 beacon node.

Asset tokenization allows converting ownership rights to real-world assets such as real estate into digital tokens on blockchain. This provides benefits like increased liquidity, fractional ownership, and global access for investors. Several startups are developing platforms for real estate asset tokenization using various models. For example, Brickblock allows investors to purchase tokenized shares of individual properties. Challenges include ensuring regulatory compliance, addressing legal issues around property rights, and developing trusted technology solutions. Overall, asset tokenization has potential to significantly transform traditional asset markets.

The presentation outlines common use cases for NFTs, including digital art, collectibles, blockchain games, and IP management. Legal and regulatory considerations can be found on the last few slides.

Cryptocurrencies like Bitcoin have significant economic, social, and political impacts. Economically, they increase global investment and financial access but also create high volatility. Socially, they enable pseudonymous transactions but also allow for potential criminal uses of anonymity. Politically, they can undermine government control of currency but also make regulation difficult. Overall, the document discusses both benefits and challenges of cryptocurrencies across many domains.
