Data that is stored in the vault is often encrypted for greater security. The vault is the only location where a token is connected back to its original value. However, you should proceed with caution and carefully consider the risks involved before investing in tokenization. The algorithm behind ML models relies entirely on computation, which itself requires numbers to compute. So, text must be turned into numbers before ML models can work with them.
Benefits of Tokenization For Investors & Enterprises
With substantial growth projected, we’re committed to helping businesses leverage tokenization for enhanced transparency, liquidity, and investment accessibility across diverse industries. To invest in tokenization, investors can explore tokenized assets on platforms that specialize in tokenization of securities and real-world assets. Start by researching platforms that offer regulatory-compliant investments, such as security token offerings (STOs). Investors can buy tokens representing fractional ownership of assets, with the option to trade or hold these tokens depending on market conditions. Understanding the platform’s compliance and security measures is essential before committing to RWA tokenization investments. Tokenization is the process of transforming ownership rights of an asset—whether physical or digital—into digital tokens on a blockchain.
By lowering the entry cost for participants, tokenization not only makes financial systems more efficient but also more accessible. Unlike traditional systems where settlements may take days (e.g., T+2), blockchain allows for immediate transaction execution (T+0). This not only increases market efficiency and accessibility but also introduces significant cost savings and performance enhancements through decentralized financial market infrastructure (dFMI) such as blockchains and oracles. In a credit card transaction, for instance, the token typically contains only the last four digits of the actual card number. The rest of the token consists of alphanumeric characters that represent cardholder information and data specific to the transaction underway.
- Programmability provides a solution—a piece of code that ensures the buyer’s money and the seller’s asset are locked in and then exchanged at the same moment.
- Each token has enough information for models to learn relationships, but the vocabulary is not so large that training becomes inefficient.
- Tokenization is important to this process as it defines the model’s vocabulary and structures the input into a form the model can compute.
Tokenization (data security)
- Tokenized assets require connection to a variety of additional real-world datasets.
- A high-value token acts as a direct surrogate for a PAN in a transaction and can complete the transaction itself.
- Encryption is a process during which sensitive data is mathematically changed, but its original pattern is still present within the new code.
- The sent_tokenize function is used to segment a given text into a list of sentences.
After tokenization, techniques like attention or embedding can be run on the numbers. Training becomes efficient, but performance may plummet since each token doesn’t contain enough information for the model to learn token-token relationships.

Whether you’re splitting text into words or sentences, tokenization in NLTK provides powerful tools like word_tokenize and sent_tokenize to handle the complexities of natural language. Mastering tokenization is a crucial step toward unlocking the full potential of NLP in Python. Tokenization is the process of splitting text into smaller, manageable pieces called tokens. These tokens can bloomberg catches cryptocurrency fever be words, subwords, characters, or other units depending on the tokenization strategy.
Tokenizer training
The intermingling of PII with application data also makes it very difficult to meet compliance requirements like data residency. For data residency, you need to extract and regionalize PII based on the customer’s country and the areas of the world where you’re doing business. Both encryption and tokenization are necessary to solve challenges around data privacy, but tokenization is better suited to certain use cases than encryption, as described below. Instead, they serve as a map to the original value or the cell where it’s stored.
Cross-Border Payments and RWA
Tokenization in blockchain refers to the issuance of a blockchain token, also known as a security or asset token. A real-world asset is tokenized when it is represented digitally as cryptocurrency. More recently, tokenization was used in the payment card industry as a way to protect sensitive cardholder data and comply with industry standards. The organization TrustCommerce is credited with creating the concept of tokenization to protect payment card data in 2001.
Types of tokens
Data pseudonymization is especially important for companies who work with protected individual data and need to be compliant with GDPR and CCPA. In order for data to be pseudonymized, the personal reference in the original data must both be replaced by a pseudonym and decoupled from the assignment of that pseudonym. If the personally identifiable information (PII) has been replaced in a way that is untraceable, then the data has been pseudonymized.
How Tokens Work
There might be application requirements that impact the token format and constraints. The consistency of the tokenization process is an important tradeoff for you to consider. It allows you to perform some operations like equality checks, joins, and analytics but also reveals equality relationships in the tokenized dataset that existed in the original dataset. In this case, you need a consistent tokenization method (sometimes called ‘deterministic tokenization” because tokens might be generated by a deterministic process).
Visa CEO Ryan McInerney said on a second-quarter 2025 earnings call with analysts in April that tokenization also plays a role in artificial intelligence-facilitated commerce.

ERC-20 defines fungible tokens; ERC-721 defines NFTs (non-fungible tokens). For example, with COMP (Compound protocol), holders can propose and vote on changes to interest rates or protocol upgrades. To ensure compatibility with wallets, exchanges, and dApps, most tokens follow a token standard.
Utility Tokens
With very large tokens (e.g., at the sentence level), the vocabulary becomes massive. The model’s training efficiency drops because the matrix to hold all these tokens is huge. Performance plummets since there isn’t enough training data for all the unique tokens to meaningfully learn relationships. Used in models like BERT and GPT, subword tokenization helps handle rare words, typos, and multilingual input by piecing together unfamiliar terms from known subword parts.
You might want to be able to search the tokenized data store for a record where the first name is equal to “Donald” or join on the tokenized first name. If you ripple news ripple price and xrp latest wanted the same feature with tokenization, you would choose to generate random tokens (sometimes called non-deterministic tokens). With random tokens, tokenizing the same value twice will yield two different tokens. The table above might end up looking like the one below, with the First Name column replaced with random tokens. So the original value is secure, even if you leave all of the tokens in the databases, log files, backups, and your data warehouse.
