In short
Blockchain’s “reality” and likely evolution, compared to how TCP/IP grew from simple email into the internet.
Guests
Professors Marco Ian Sidi and Kareem Lakhani (blockchain researchers/academics).
Key claims
Blockchain is still early but could become a foundational “system of record” for internet transactions, reshaping economic and social systems over multiple phases.
Notable examples
Phase 1 “single-use” likened to Bitcoin as an alternative two-way payment method. Phase 2 “localization” likened to private/distributed-ledger blockchain networks in financial services connecting limited participants. Phase 3 “substitution” likened to newer cryptocurrencies beyond Bitcoin requiring broad adoption and creating government/institution/consumer challenges. Phase 4 “transformation” likened to smart contracts that automatically pay suppliers upon shipment delivery.

Blockchain is still in its infancy, but many believe it could revolutionize business and government, creating new foundations for our economic and social systems. Professors Marco Ian Sidi and Kareem Lakhani compare blockchain's possible evolution to that of the internet communications protocols called TCPIP.
1:14TCPIP was originally invented for small-scale two-way email exchanges, but it ultimately evolved to become the basis for the entire internet. Similarly, blockchain was invented as a peer-to-peer network that enabled two-way payment transactions of the cryptocurrency Bitcoin. But like TCPIP, blockchain has outgrown its original purpose. It now has the potential to become the system of record for all internet transactions. In other words, it could become what is called a foundational technology, creating a new technological infrastructure for our economic and social systems. However, this radical change won't happen overnight.
1:50Ian Seedy and Lakhani suggest that blockchain will likely pass through several phases before fully reshaping the economy. First is the single-use phase. Here, the technology is used in applications low in novelty and not requiring coordination among many different parties. For TCPIP, email was an inexpensive single-use application. For blockchain, Bitcoin offered immediate value to those who used it simply as an alternative two-way payment method. Second is localization. Here, the technology spreads to more novel innovations that need only a limited number of users to create immediate value. We see this now in the financial services sector's use of local, private blockchain networks to connect through a distributed ledger.
2:34During the third phase, substitution, the technology faces the highest barriers to adoption. It's used in new applications that build on existing ones, but intense coordination is required. For blockchain, think cryptocurrencies that have grown out of Bitcoin. They need widespread adoption to be of any value, but they also pose challenges for governments, institutions, and consumers. In the last phase, transformation, truly novel applications emerge that require coordinating many actors and unifying institutional standards. The most transformative blockchain application to date may be self-executing smart contracts that can automatically trigger a payment to be sent to a supplier as soon as a shipment is delivered.
3:18Blockchain faces many hurdles. An executive should think carefully about the risks. However, there's little doubt that blockchain will affect your business. The big question is when to stop experimenting and really press on the accelerator.

Blockchain’s impact will be enormous, but it will take decades for it to seep into our economic and social infrastructure.
True blockchain-led transformation of business and government is still many years away. That’s because blockchain is not a “disruptive” technology, which can attack a traditional business model with a lower-cost solution and overtake incumbent firms quickly. Blockchain is a foundational technology: It has the potential to create new foundations for our economic and social systems.
But while the impact will be enormous, it will take decades for blockchain to seep into our economic and social infrastructure. The process of adoption will be gradual and steady, not sudden, as waves of technological and institutional change gain momentum.
