From Transactions to Records: Reconceptualizing Blockchain Systems through a Lifecycle Lens
This paper reconceptualizes blockchain systems as record management frameworks rather than mere transactional infrastructures by applying ISO 15489-1:2016 principles to define a seven-stage data lifecycle, offering a meta-level perspective to better address challenges in governance, analytics, and crypto-crime investigation.

The Big Idea: It's Not Just About the "Money," It's About the "Paperwork"
Imagine you are trying to solve a mystery. Most detectives looking at cryptocurrency only look at the transactions—the moment money moves from Person A to Person B. They are like people watching a car drive down the street, trying to figure out where it's going.
The authors of this paper say: "Wait a minute. You're only looking at the car driving. You're ignoring the factory where the car was built, the dealership that sold it, the maintenance logs, and the scrapyard where it ended up."
They argue that we need to stop looking at blockchain just as a "money transfer system" and start looking at it as a giant, digital filing cabinet (a records management system). They want to apply the rules of how we manage physical documents (like passports or birth certificates) to digital coins.
The Core Analogy: The Passport Lifecycle
To explain how this works, the authors use the example of a National Passport. They break the life of a passport into seven stages. They then argue that a Bitcoin or a digital token goes through these exact same seven stages, even though it's invisible code.
Here are the Seven Stages of a crypto-asset's life, translated from "bureaucrat-speak" to everyday language:
- Creation (The Birth):
- Passport: You apply, they take your photo, and the government prints the book.
- Crypto: A new coin is "mined" or created by a computer. It's born with a digital ID.
- Review & Approval (The Inspection):
- Passport: An officer checks your documents to make sure you aren't a criminal and that your photo looks like you.
- Crypto: A network of computers checks the math to make sure the coin is real and hasn't been spent before.
- Publication (The Handover):
- Passport: You get the passport in the mail, and it's registered in the government database. It's now "active."
- Crypto: The coin is added to the public blockchain. Everyone can see it exists.
- Active Use (The Journey):
- Passport: You travel, get stamps in your passport, and use it to cross borders.
- Crypto: You spend the coin, use it as collateral, or trade it.
- Revision (The Update):
- Passport: You get married and change your name. You get a new passport, but the old one is linked to the new one in the system.
- Crypto: You spend the coin. The "old" coin disappears, and a "new" coin is created for the new owner. The history of the old one is never erased; it just gets updated.
- Retention (The Filing):
- Passport: Even after your passport expires, the government keeps a digital record of it for 20 years for security checks.
- Crypto: The record of every single transaction is kept forever on thousands of computers. It never gets deleted.
- Disposition (The End):
- Passport: You throw away the expired paper book, but the government keeps the digital file.
- Crypto: You lose your password (the coin is "dead" to you), or you send it to a "burn address" (it's destroyed). But the record that you lost it or burned it stays on the blockchain forever.
Why This Matters: The "Hidden Side of the Iceberg"
The paper claims that current investigators are like people looking at the tip of an iceberg (the transactions). They miss the "hidden side" (the lifecycle).
The Problem with "Privacy" and "Off-Chain" Data
The authors point out a tricky problem. In the real world, if you lose a paper file, it's gone. In the crypto world, the record of the file never goes away, even if the value is gone.
They also highlight a "boundary problem." Imagine a bank vault (the blockchain) and a safe deposit box at a private bank (an exchange or a "Layer 2" network).
- The blockchain is like a public glass wall: everyone can see the vault.
- The private bank is like a solid wall: you can see the money go in and out, but you can't see what happens inside.
This makes it hard for investigators to see the full "lifecycle" if the money moves between these two worlds.
The Three Examples They Tested
To prove their theory works, they applied this "Passport Lifecycle" to three different types of crypto:
- Bitcoin (The UTXO System):
- Think of this like a stack of physical cash. When you spend a $10 bill, that specific bill is gone, and you get a new $10 bill (or two $5s) in return. The paper trail of the old bill remains, but the physical bill is "spent."
- Tether (The Fungible Token):
- Think of this like a digital gift card. It's tied to an account. When you spend it, the balance goes down. The paper trail shows the balance changing, but the "card" itself is just a number in a database.
- NFTs (The Non-Fungible Token):
- Think of this like a digital painting. The "record" of who owns the painting is on the blockchain. But the actual painting (the image file) might be stored on a different server (like a cloud drive). If that cloud drive deletes the image, the blockchain still says "This person owns the painting," even if the painting is gone.
The Main Takeaway
The paper concludes that blockchain isn't just a machine for moving money. It is a system for managing records that has some very weird, unique rules:
- You can't delete records: Once a transaction is written, it stays there forever (unlike a Word document you can delete).
- The "Asset" and the "Record" are different: You can destroy the value (burn the coin), but the record of the destruction stays.
- Privacy is tricky: Some technologies try to hide the "Active Use" stage, making it hard to see the full lifecycle.
By viewing crypto through this "Lifecycle Lens," the authors believe we can better understand how to regulate it, investigate crimes, and manage the data responsibly, rather than just chasing the money as it moves from one wallet to another.
