Blockchain, the technology that functions as a digital notebook to support loans in Colombia.

Despite advances in digitalization within the Colombian financial system—such as the expansion of mobile banking and e-wallets—key processes remain complex and slow.

However, blockchain technology is transforming this scenario by functioning as a shared and secure digital notebook.

This is a decentralized database where all transactions and backups are recorded chronologically, transparently, and unalterably. Each transaction is recorded in a "page" (block) that links to previous transactions, creating a reliable chain visible to all authorized participants.

Fintech companies have begun implementing solutions to streamline these processes. Among them is Anzi Finance, an international startup that arrived in Colombia at the end of 2024.

This company developed the country's first blockchain-based digital credit backup system, which has significantly reduced the time required to activate collateral in the event of default.

“Blockchain isn't just synonymous with cryptocurrencies. It's a technology that helps with traceability, automation (thanks to smart contracts), and security in the recording of important processes, without relying on so many intermediaries or bureaucratic procedures,” explains Matías Marmissolle, the company's CEO.

The technological proposal is based on converting traditional collateral into a programmed digital file, known as a token. This file contains the terms of the credit agreement and is directly linked to the contract . If a default occurs, the system can automatically trigger a disbursement order in favor of the lender.

Unlike the traditional model, where a claim could take between four and twenty weeks, with blockchain, that time is significantly reduced, and it can be resolved in a matter of days or even minutes. This is because the process is automated and does not require multiple authorizations or handling of physical documents.

"This solution makes it easier for all financial institutions to recover part of their loaned capital in less time, without complications, thus improving their cash flow," says Marmissolle.

The main transformation of this technology goes beyond speed. By integrating smart contracts, collateral conditions are automatically executed if the agreed payment is not met. This reduces the need for internal or third-party validations, reduces the margin for human error, and limits discretion in collateral management.

This efficiency is especially relevant in the case of micro, small, and medium-sized enterprises (MSMEs), where time and liquidity are decisive factors.

Additionally, the immutability of data recorded on the blockchain establishes a new standard of trust for lenders and other players in the financial ecosystem, allowing for constant verification of the status of backups.

Currently, some fintech companies are testing mechanisms that allow loans to be backed by real assets—such as crops or livestock—that have been converted into digital assets.
