DeFi – why finance needs decentralization?

What is DeFi? In what ways is it better than traditional financial solutions?

DeFi stands for "decentralized finance". It is an umbrella term used to describe the various financial applications of Blockchain technology aimed at pushing financial intermediaries away. Blockchain allows multiple entities to store copies of transaction history, removing it from the control of one central source. This is what decentralization means. 

What is the difference in practice? When you pay by credit card for purchases, financial intermediaries such as your bank or Visa or Mastercard mediate in the transaction between you and the seller, having the right to stop it and register it in their private ledger. With DeFi these institutions disappear.

So what is the advantage of DeFi over traditional solutions?

Advantages of DeFi 

Blockchain = safety 

The use of Blockchain Solution technology provides a new level of transparency and security. In DeFi, every user can see where their digital assets are stored and how they are used. Transaction-securing smart contracts, once implemented, are permanently recorded and cannot be changed. In practice, this means that transactions are only executed if both parties comply with the terms of the contract. 

Exclusive control in the hands of users

Most banks are quickly adapting to the online world, tempting users with new applications or solutions to facilitate transactions such as the Polish Blik. However, the money on user accounts is still under the control of the bank. In this respect DeFi is far ahead. Only the owner has the private key to his decentralized wallet and only he has control over the funds stored there.

Democratization of development

Changes in traditional finance take up to decades, and all decisions from the user's perspective are made behind closed doors. In DeFi, innovations are made in real time, and the development itself reflects the idea of democratizing finance. In DeFi, there are no permissions specifying who can introduce new code to the network, so theoretically it is possible for anyone to do so. Moreover, users of the solutions are often involved in the process of voting on changes.

High return on investment

Traditional banks for the public will continue to be the best place to deposit funds for a long time to come. But in fact, why? After all, interest rates are lowered more and more every year, and fees remain the same. 

In contrast, DeFi financially incentivizes users to bet or borrow assets. The interest that would have gone to the bank when borrowing the customer's money is paid directly to the lender. So with DeFi, the user earns interest that is usually retained by the bank.

DeFi Loans

In fact, in the beginning, all lending was peer-to-peer. People lent funds to each other based on more or less forced trust. For obvious reasons, this arrangement was high risk for the lender. Banks have solved the problems with credit trust, but have added additional costs and levels of regulation. 

Crypto lending allows for a return to a peer-to-peer model. They significantly reduce costs by removing intermediaries while providing complete transaction security. 

DeFi allows peer-to-peer lending to exist directly tailored to borrowers and lenders. Typically, a crypto loan is secured by a smart contract and cryptocurrency assets. The interest rate, on the other hand, is based on the value of the funds that the borrower uses as collateral. The loan can be made in both cryptocurrencies and fiat currencies. 

Support for small entrepreneurs

Lending to small and medium-sized entrepreneurs is one of the most important aspects of traditional finance that needs to change. They are the ones who most often struggle to get funding. Crypto loans are a way to make it significantly easier for them.

The key factor to obtaining such a loan is the amount of cryptocurrency funds that the borrower is able to put up as collateral.  Due to the volatility of cryptocurrencies, loans are very much collateral. In practice, this means that they require a collateral ratio of at least 150%, which provides lenders with some safeguards in managing risk. In contrast, traditional creditworthiness is not considered in the evaluation process.

An example of a solution that provides such support to entrepreneurs is Amplify, which additionally combines another plus of cryptocurrency lending: 24-hour availability.

DeFi – what next?

Although DeFi has been on the market for only a short time, it is already a viable alternative to many financial services that have been out there for decades. The growing popularity of DeFi shows that users all over the world want to increase control over their finances and start defining the terms on which they use the services.

What is Account Abstraction?


10 Nov 2023
What is Account Abstraction?

Account abstraction is a new way of thinking about how users interact with blockchains. Instead of using traditional externally owned accounts (EOAs), account abstraction allows users to create and manage their accounts using smart contracts. This has a number of potential benefits, including improved security, enhanced privacy, and increased flexibility.

What is account abstraction?

Account abstraction is a concept that, at its core, aims to simplify the user's interaction with blockchain networks. It is a transformative approach that seeks to mask the technicalities of blockchain operations from end-users. It is making transactions as straightforward as sending an email. Account Abstr. allows users to interact with the blockchain without worrying about the underlying technical details.

How does account abstraction differ from the traditional model?

In the traditional account model, each user has an EOA. EOAs are controlled by private keys, which must be kept secret in order to protect the user's funds. Acc. abstraction allows users to create and manage their accounts using smart contracts.

Historical Context

The journey towards acc. abstraction began with the first generation of blockchain technologies, characterized by their "one-size-fits-all" approach to account management. Bitcoin, for instance, introduced the concept of accounts and transactions in a form that was accessible to tech-savvy individuals but remained perplexing to the layperson. Ethereum expanded on this by introducing smart contracts, which opened the door to programmable transactions but did not alter the fundamental account structure. The idea of acc. abstraction has been discussed in the Ethereum community for several years as a part of various Ethereum Improvement Proposals (EIPs), particularly as a feature to be potentially implemented in Ethereum 2.0. It is a direct response to the need for a more versatile and user-centric design that can cater to a broader audience and spur the widespread adoption of blockchain technology.

The Technicalities of Account Abstraction

Account abstraction is not merely a theoretical construct but a technical innovation with specific mechanisms underpinning its operation. In essence, it alters the way transactions are initiated and executed within a blockchain network.

How Account Abstraction Works

Under traditional blockchain models, initiating a transaction involves an externally owned account (EOA) signing a transaction with a private key. This transaction is then broadcast to the network for validation and inclusion in the blockchain. Account abstraction, however, replaces this process with a more flexible one. Here, every account is a smart contract, and transactions are messages sent through these contracts. These smart contracts can encode complex rules for transaction validation, beyond what EOAs can do, such as multi-signature requirements or conditional transactions based on certain triggers.

The technical crux of account abstraction lies in the smart contract’s ability to define its own conditions for transaction execution. This means that user accounts can have unique security protocols or automated operations without the user needing to understand the underlying smart contract code.

The Benefits of Account Abstraction

The implications of account abstraction are profound, offering a range of benefits that can enhance the blockchain experience for users and developers alike.

Improved User Experience

One of the most significant advantages of account abstraction is the improvement it brings to user experience. By abstracting away the complexities of key management and transaction rules, it presents a more intuitive interface for users.

Enhanced Security Features

Account abstraction also allows for the implementation of advanced security measures. Since each account can define its own logic, users can tailor their security settings to their specific needs. For instance, one might set up an account that requires additional verification for transactions exceeding a certain value or restricts withdrawals to certain addresses.

Future Implications

The future implications of account abstraction are vast. As the technology matures, it could become a standard feature of blockchain networks, potentially making the current distinction between user accounts and smart contracts obsolete. This could lead to a new wave of blockchain applications that are both powerful and accessible, bringing us closer to the vision of blockchain technology as a seamless part of everyday life.

Challenges and Considerations

Technical Limitations

One of the primary technical challenges of Acc. abstraction lies in its integration with existing blockchain protocols. Current networks are optimized for the EOA model, and introducing a new account structure necessitates significant changes to the core protocol. This includes modifications to the way transactions are propagated in the network, how gas fees are calculated, and how the state of the blockchain is managed. Ensuring that these changes do not compromise the network's performance or security requires careful planning and extensive testing.

Compatibility with Current Systems

Another consideration is the compatibility of account abstr. with the vast ecosystem of existing blockchain applications and services. Wallets, exchanges, and other services have been built around the traditional account model. Transitioning to an acc. abstraction model will require these services to update their infrastructure, which may be a complex and resource-intensive process. Furthermore, there is a need for standardization across the industry to ensure that different implementations of account abstr. can work seamlessly together.


Acc. abstraction represents a significant leap forward in the quest for a more user-friendly blockchain experience. By streamlining the transaction process and offering enhanced security features, acc abstraction has the potential to make blockchain technology more accessible to a broader audience. However, the path to widespread adoption is not without its obstacles. Technical challenges and compatibility issues must be carefully navigated to integrate it into the existing blockchain landscape.
