nmohapatraFrom Delphi to Decentralization: The Evolution of Oracles in Web3
For thousands of years, oracles were understood to be the mouthpieces of the Gods, communicating their intentions, instructions, and desires for us in the mortal world. Their messages were veiled in metaphor and often misinterpreted or heard too late. In the web3 context, oracles perform a distinctly different function. (I’m guessing that doesn’t surprise you much.) What both versions have in common is that they answer the questions posed to them by the living mortals who seek to use them. An...

Hopefully, part one gave you a clearer sense of what a blockchain is at a conceptual level. Still, it’s dry and a bit dense, so to expand on that understanding and why you would actually use a blockchain over a traditional database, let’s explore a hypothetical scenario in which a blockchain could be used, followed by a comparison between traditional databases and blockchains.
Process: The iPhone's journey starts with the extraction of raw materials like lithium (for batteries), aluminum (for the casing), and gold (for circuitry).
Blockchain Entry: Each batch of raw materials is tagged with a unique digital identifier (like a QR code or RFID tag) as it's mined. Information such as the extraction date, location, quantity, and the miner's details are recorded on the blockchain.
Purpose: This ensures the materials are ethically sourced and allows Apple to audit its suppliers for compliance with environmental and labor standards.
Stage 2: Component Manufacturing
Process: These raw materials are then shipped to different factories for processing into components – for example, lithium into batteries, aluminum into casings, etc.
Blockchain Entry: When a component is made, its creation is logged on the blockchain along with details like the manufacturing date, factory location, quality control results, and the transportation method to the assembly plant.
Purpose: This helps in quality assurance and tracking any issues back to the respective component and batch.
Stage 3: Assembly of the iPhone
Process: Components are shipped to assembly plants where iPhones are assembled.
Blockchain Entry: The assembly of each iPhone, along with its serial number, is recorded.
Data includes the assembly date, workers involved, and quality check results.
Purpose: Ensures transparency in manufacturing and allows tracking of each device through its manufacturing process.
Stage 4: Distribution and Retail
Process: The finished iPhones are then packed and shipped to various countries for sale.
Blockchain Entry: Shipping details, including the carrier, route, and arrival times at warehouses and retail outlets, are recorded.
Purpose: Monitors the distribution process for efficiency and security, ensuring products aren't lost or tampered with during transit.
Stage 5: Consumer Purchase
Process: A customer buys the iPhone from a retail store or online.
Blockchain Entry: The sale is recorded, linking the specific iPhone to its buyer (while respecting privacy laws).
Purpose: Helps in customer service and warranty claims, ensuring the product's authenticity.
Transparency and Trust
Blockchain: Offers a high level of transparency. Every transaction or record is visible to all participants in the network, which is particularly beneficial in supply chains involving multiple stakeholders who might not have inherent trust in each other.
Database: Traditional databases are typically controlled by a single entity. Transparency depends on the willingness of this entity to share information, which might not be ideal in a multi-stakeholder environment.
Immutability and Security
Blockchain: Provides immutability. Once data is recorded on a blockchain, it cannot be altered without consensus, which significantly reduces the risk of fraud and data manipulation.
Database: In traditional databases, data can be altered or deleted by the database administrators, which might pose a risk in terms of data integrity and trustworthiness.
Decentralization
Blockchain: Operates on a decentralized network. There is no single point of failure, and the data is not under the control of any single entity. This can enhance security and resilience against attacks or failures.
Database: Centralized nature means there is a single point of failure. If the database goes down or is compromised, it can affect the entire system.
Efficiency and Speed
Blockchain: Generally slower due to the consensus mechanisms required to validate transactions. This can be less efficient for supply chain operations that require high-speed transactions.
Database: More efficient in terms of transaction speed. Databases can handle a large number of transactions quickly, which is advantageous for supply chains with high throughput needs.
Cost and Complexity
Blockchain: Implementation can be complex and costly, especially for public blockchains which require significant computational resources for validation processes like Proof of Work. (though depending on your application, you can use cheaper and more efficient means like Prook of stake blockchains or Zero Knowledge Proofs)
Database: Typically less expensive and complex to set up and maintain than a blockchain system.
Use-Case Suitability
Blockchain: Ideal for supply chains where transparency, security, and trust are paramount, especially in cases involving multiple organizations or when counterfeiting, fraud, and compliance are major concerns.
Database: Better suited for supply chains that are managed by a single entity or where trust is not a significant issue, and where speed and cost-efficiency are critical.
This certainly won’t be my last word on blockchain. A topic so vast can’t be fully contained in one explainer, and for all its virtues and promises, there are liabilities and impacts to consider (its energy and environmental costs are worthy of consideration - or the fact that, ironically, many blockchain nodes are hosted on centralized servers, which undermines decentralization as an feature), but for now, understanding the basics is a jumping off point from which to grow a healthy understanding of web3 in general. In fact, knowing what you know now, consider reviewing my articles on tokenization, cryptocurrencies, metaverses, and NFTs to see if they make more sense now.
