Sikoba is developing a decentralised peer-to-peer IOU
platform using blockchain technology

What is Sikoba?

The Sikoba Concept

Sikoba is a decentralised platform based on peer-to-peer IOUs and built on blockchain technology. Participants who know and trust each other in real life grant each other credit lines in the Sikoba system. They can then pay each other without using fiat money. These peer-to-peer credit relationships are governed by contracts with specific conditions, fee structures and repayment rules.


P2P payments are already above $1 trillion annually. From almost nothing 10 years ago, P2P lending has grown to $26bn in 2015 and is expected to reach $900bn in 2024. We believe that P2P IOU systems have a similar potential and that they will soon become the next frontier in finance.

Paying with Credit

Only a few centuries ago, most trade was done on credit. In addition, many monies circulated: the government’s money (which, by the way, was not always strongest), money issued by bankers, money issued by local princes, by monasteries, by merchants. Paying with credit was a normal occurrence. The Sikoba system will allow a flowering of this monetary diversity, adapted for modern times.

The Backing of Money

There is, in the end, only one possible backing of money, and that is the promise of human work. All the mechanisms of banking and finance tend to hide this basic fact


Use Cases

The aim of Sikoba is to provide a generic platform for money systems. A few use cases are listed below.

Jump-starting local economies for the world’s unbanked

In some situations, the poverty is such that even the access to micro-credit is very limited. Here, a system such as Sikoba can help to jump-start local economies. Once people realise that bank money is not absolutely necessary, and have a tool for precisely keeping track of mutual credits and debits, even primitive economics may get a boost.

Crisis money

When a financial crisis hits, local and even central governments may find a need to quickly issue new monetary instruments. Sikoba aims to provide more flexibility than the banking system, while being linked to state-of-the art KYC systems.

Inter-company credit system

Groups of companies that do business with each other on a regular basis, for example because they are located in the same geographical region, will profit from setting up interco credit systems. Instead of systematically paying each other's invoices, they register invoices in the system and only pay residual balances after periodic clearing. As a result, less bank credit is needed.

Alternatives for micro-credits

Micro-credits carry very high interest rates, sometimes over 50% annualised. They are also difficult to obtain, especially in areas where the next bank is far away. Bank money will always be needed for some purchases, such as specialised equipment. However, when artisans and merchants start using their own credit on the Sikoba platform for local trade, their reliance on micro-credits may decrease significantly. Read More...

Local currencies

Setting up local currencies is a natural use case for Sikoba. We aim for an easy set-up that will make it possible to start a local currency even for very small communities. Local currencies using Sikoba will become easily exchangeable with other local currencies. Also, such currencies can be tied to local cost of living indices.


‘Sikoba is the result of my life-long interest in monetary theory. We see a future where money will once again be diverse, with many different issuers, with a variety of credit relationships, where people will take an active interest in the type of money they wish to use. Our aim is to provide the tools to achieve that vision.’ - Alex Kampa

In October 2018, Fantom Foundation agreed to support sikoba's research efforts until the end of 2020. The areas of research will include trustless computing, consensus algorithms and token economics.



Manas.Tech is our technology partner in charge of developing the sikoba platform using the Crystal language. The developement team is led by Gustavo Giráldez. The partnership was made possible by Nicolás di Tada, Manas.Tech founder and CEO, who has a longstanding interest in unconventional money systems.
