The future of finance: Decentralized ledgers, DeFi, and PayFi
The monetary system is a cornerstone of human society, yet its centralized control has historically posed significant risks. Financial crises and the collapse of major institutions like Silicon Valley Bank highlight the vulnerabilities of traditional financial systems, where assets can be compromised or lost without the fault of the owners.
This concern inspired Satoshi Nakamoto, who, in response to the 2008 financial crisis, introduced Bitcoin and the groundbreaking white paper, "A Peer-to-Peer Electronic Cash System." Nakamoto’s vision for blockchain was to create a decentralized ledger that eliminates reliance on a single authority, thereby offering enhanced protection for assets and establishing a financial system independent of traditional institutions.
Following this, Nakamoto introduced Bitcoin Core, the first Bitcoin wallet, which was crucial for managing transactions and supporting the Bitcoin network. This marked the beginning of a new era in decentralized finance.
A key milestone came on Bitcoin Pizza Day (May 22, 2010), when a programmer famously used 10,000 Bitcoins to purchase two pizzas. This event established Bitcoin’s fiat value and demonstrated its practical use in real-world transactions. Later that year, the launch of BitcoinMarket.com, the first centralized Bitcoin exchange, made investing in cryptocurrency more accessible.
Cryptocurrencies have the potential to parallel traditional money but offer distinct advantages through blockchain technology, such as enhanced security, decentralization, faster transactions, greater flexibility, and streamlined processes.
DeFi: Advanced financial management
The next phase of financial evolution began with the launch of Ethereum in late 2013 and the emergence of stablecoins around 2014. Ethereum revolutionized blockchain technology by introducing smart contracts and on-chain programmability. These innovations allowed developers to create decentralized applications (dApps) that automate and enforce agreements, enabling a broader range of financial services. Simultaneously, stablecoins bridged the gap between cryptocurrencies and fiat currencies, increasing their practical utility for everyday transactions.

The emergence of Ethereum and stablecoins set the stage for Decentralized Finance (DeFi), a financial technology built on secure, distributed ledgers similar to those used by cryptocurrencies. Unlike traditional banking systems, DeFi offers a comprehensive range of financial services—such as banking, insurance, and asset trading—without relying on intermediaries like banks or brokers. Instead, it leverages smart contracts on blockchains, primarily Ethereum, to facilitate transactions and agreements directly between parties.
DeFi aims to democratize finance by replacing centralized institutions with peer-to-peer networks. It provides services including everyday banking, loans, mortgages, and complex asset trading, making financial services more accessible and potentially reducing costs while enhancing transaction speed. DeFi is part of a broader trend towards programmable money and financial instruments that are more customizable and automated, improving efficiency and expanding reach.
PayFi: Harnessing the time value of money
Lily Liu, President of the Solana Foundation, introduced PayFi, a new concept designed to leverage blockchain’s programmability and instant settlement capabilities to maximize the time value of money. Liu stated, “On-chain finance can enable new financial primitives and product experiences that are impossible in traditional or even Web2 finance.”

The Time Value of Money (TVM) principle posits that money's value changes over time; specifically, money available now is worth more than the same amount in the future because it can be invested or spent immediately to generate returns. This principle explains why interest is paid on deposits and charged on loans, as people value immediate access to money and are willing to pay extra for it.
In light of this, Liu highlighted two innovative applications of PayFi:
"Buy now, pay never", which allows users to finance purchases using future interest from their deposits or loans.
"Creator monetization", which enables creators to receive immediate cash by exchanging a portion of their future earnings for enhanced cash flow.
PayFi aims to simplify accounts receivable financing, which often burdens small and medium-sized enterprises with complex regulations and risk assessments, limiting their ability to fully capitalize on TVM. This issue is exacerbated in cross-border payments, where traditional networks like SWIFT force institutions to hold large pre-funded accounts globally—over $4 trillion, according to a 2022 Arf study—resulting in significant TVM loss.
By leveraging blockchain technology, PayFi seeks to expedite settlements and improve the accessibility of financial services, potentially boosting capital turnover. This includes tokenizing real-world assets and converting physical or traditional assets into digital tokens to facilitate easier trading and integration into online financial transactions. By applying TVM to everyday payments and moving these transactions to the blockchain, PayFi aims to streamline financial processes.
While PayFi builds on existing concepts, it strives to revolutionize financial transactions by integrating blockchain technology into current systems. This integration aims to offer superior user experiences and transform our interaction with financial services. The full impact of PayFi on these systems will become clearer over time.
