Answer Key
Stefan Thomas suggests that while smart contracts have generated excitement, they haven't seen widespread adoption in real-world products, unlike technologies like Docker which were developed around the same time and now underpin much of the internet infrastructure.
Codius is a platform that runs smart contracts within isolated containers, making it ledger-agnostic and able to interact with any cryptocurrency or traditional system. This contrasts with blockchain-integrated smart contracts that are tied to a specific ledger.
According to Miguel Vias, early discussions about smart contracts at Ripple, which included Vitalik Buterin, predated the formal development of Ethereum, suggesting that the ideas behind decentralized computing were circulating within the Ripple community early on.
Two key regulatory actions by the OCC under Brian Brooks were clarifying that banks could provide cryptocurrency custody services and providing guidance on banks holding reserves for stablecoins, both aimed at integrating digital assets into the traditional financial system.
Stefan Thomas likens the Interledger Protocol (ILP) to a "shipping container for value." This analogy illustrates ILP's role in providing a standardized and interoperable way to move any form of value across different and independent payment networks.
Stefan Thomas states that Bitcoin miners are primarily incentivized to hash as efficiently as possible to earn rewards, without a direct incentive for network security or governance. In contrast, Ripple validators are chosen by users and risk losing trust and influence if they act against the network's interests.
The layered architecture of the Interledger Protocol includes the application layer (for specific use cases), the Interledger layer (for routing packets), and the ledger layer (where actual settlement occurs). The transport layer also provides basic communication services.
To use Codius, both parties would agree on a set of independent hosts to run the smart contract and agree on the terms of the contract. The user would then upload the contract to these hosts, which would act as validators to ensure the terms are met before payment is released.
The "Why XRP Exists" article suggests that traditional centralized banking systems might oppose XRP because it has the potential to disrupt their global monopoly over currencies and financial systems, offering a decentralized alternative that could reduce their control and influence.
Stefan Thomas explains that Bitcoin's consensus relies on probabilistic finality based on hashing power, allowing for potential rollbacks if a longer chain with more hashing power emerges. XRP's consensus, on the other hand, achieves deterministic finality through agreement among a set of trusted validators selected by network participants, making rollbacks impossible once consensus is reached.
