DeFi Impact
DeFi offers exciting opportunities and has the potential to create a truly open, transparent, and immutable financial infrastructure. Moreover, the system's composability allows anyone to combine multiple applications and protocols, creating new and exciting services.
Efficiency: While much of the traditional financial system is trust based and dependent on centralised institutions, DeFi replaces some of these trust requirements with smart contracts. The contracts can assume the roles of custodians, escrow agents, and central counterparties (CCPs). Additionally, token transfers are much faster than any transfers in the traditional financial system. In fact, transfer speed and transaction throughput can be further increased with Layer 2 solutions, such as sidechains or state and payment channel networks.
Transparency: DeFi applications are transparent. All transactions are publicly observable, and the smart contract code can be analysed on chain. Additionally, financial data is publicly available and may be used by researchers and users. The availability of historical (and current) data is a vast improvement over traditional financial systems, where much of the information is scattered across numerous proprietary databases or not available at all. This benefit is particularly relevant in the event of a crisis. As such, the transparency of DeFi applications may help mitigate undesirable events before they arise and provide a much faster understanding of their origins and potential consequences when they emerge.
Accessibility: By default, DeFi protocols can be used by anyone. As such, they may potentially create a genuinely open and accessible financial system. In particular, the infrastructure requirements are relatively low, and the risk of discrimination is almost nonexistent due to the lack of identities.
If regulations demand access restrictions, such as security tokens, such restrictions can be implemented in token contracts without compromising the settlement layer's integrity and decentralisation properties.
Composability: DeFi protocols are often compared with Lego pieces: the shared settlement layer allows these protocols and applications to interconnect. On chain fund protocols can use decentralised exchange protocols or achieve leveraged positions through lending protocols.
Any two or more pieces can be integrated, forked, or rehashed to create something entirely new, and anything previously created can be used by an individual or other smart contracts. This flexibility allows for an ever expanding range of possibilities and unprecedented interest in open financial engineering.
Innovation: On the one hand, developers use smart contracts and the decentralised settlement layer to create trustless versions of traditional financial instruments. On the other hand, they are creating entirely new financial instruments that could not be realised without the underlying public blockchain. Atomic swaps, autonomous liquidity pools, decentralised stablecoins, and flash loans are a few examples that show this ecosystem's great potential. We are witnessing the disruption of how governments, companies, and people interact with financial products. While some industries will be more impacted, the future of finance will affect nearly every sector.
