Transforming Trust & Money
with native protocols for incorruptible reputation, an algorithmically stable currency and a truly decentralized consensus


The Semada Mission
Re-think money

50 million americans have little to no access to financial services. On a global scale, almost 2 billion people have no access to financial services whatsoever. Many industries, even though legal, have been denied financial inclusion, a result of being deemed risky or credit unworthy by banks. Increasing transaction costs and predatory financial services have become the norm. The digital economy requires a new type of financial infrastructure that is transparent, reduces counterparty risks, lowers cost of mediation, provides access and inclusion for everyone.

Freedom of transaction

Semada is a decentralized network, that is censor resistant, offers immutability, instant finality of transactions, with no requirement for trusted agents or trusted setup. An open network standard for anyone or any institution to adopt, to move value seamlessly, which no private or state actor can control.

Efficient money

Most cryptocurrencies have failed to replace cash money due to inherent variability and volatility. Semada provides an efficient alternative, the “reactive algorithmic stable currency (RASC).” Semada network deploys multiple tools to safeguard against heavy volatility swings, and inflates when there is a true demand. Semada also removes the expensive and overcollateralized reserve requirements.

Effective contracting

Semada provides a smart contract layer which is a decentralized, eternal, immutable record of transactions, with self-executing, self-regulating decentralized business contracts, using a new process (decentralized reputation that motivates continually improving protocols for business transactions), motivated by secure and meaningful reputation (meaningful = valuable).

Designed By Economists & Technologists
Interdisciplinary Research:

Semada Research Institute (SRI) brings together leading academics in the fields of mathematics, economics, finance, cryptography and software engineering, to develop economic models and technology solutions that solve global economic problems.

Technology Development:

Semada Labs’s (Labs) has a globally distributed team of engineers and scientists. Semada advanced currency labs team and Semada research institute (SRI) are co-developing the "Open currency network framework" (OCNF), and other protocols, to create Semada distributed ledger core (SDLC).
Core Protocols
Proof Of Reputation Consensus (PoR)

Our research leads us to believe that Proof of Stake (PoS) with fungible monetary staking, leads to corruptible behavior, and inconsistencies can occur in maintaining the truthful chain as the attacks can become cheaper, which can distort the source of truth.

Semada Proof of Reputation (PoR) consensus removes the corruptible influence of money by shifting stakes to intangible reputation. This protocol results in true decentralization and the associated economic security and stability, leading to improved behavioral incentivization in a positive reinforcement loop.

PoR is resistant to Byzantine faults, 51% attacks, stake grinding, the nothing-at-stake problem (tragedy of the commons), Sybil attacks, tyranny of the majority, liveness faults, DoS attacks, perverse delegates, censorship, and soft protocol changes.

Reactive Algorithmic Stable Currency (RASC)

Why do we need a stable currency?

Stable currency is more efficient and gives predictability for business transactions. This allows individuals and businesses to make more complex transactions/contracts for the future, which allows them to get more value out of their power (investment/talent/time/energy/resources/assets), and creates wealth/value.

There hasn’t been the opportunity to create decentralized currency before, because the technological tools weren’t previously available to create a truly stable currency. Most currency in history has not been very stable--the USD is a historical anomaly in that it’s been stable for 80 years, due to a unique confluence of historical events.... But decentralized, digital, algorithmic currency has the opportunity to be very stable, if it is designed well, with the ability to improve in response to demands from the market, and its decentralized regulators are properly motivated to keep it stable, secure, and efficient.

How is reactive algorithmic stable currency (RASC) different from other stable currencies?

First, RASC removes the expensive overcollateralization reserve requirements, keeping it truly decentralized; it’s more nimble and reactive. Semada network has a superior governance process based on secure and meaningful reputation, that will filter down to the best choices. This will allow stable changes in the protocol to react to the market, which will therefore enable it to maximize between efficiency and security, and choose the optimal response to market needs.


Mathematician and dynamical systems expert, Prof. Craig Calcaterra, and Prof. Wulf Kaal, a  law and economics scholar, collaborated and developed the proof of reputation (PoR) consensus and currency stability mechanism as core protocol layers over the course of three years of academic research. These protocols form the foundation for the Semada Research Institute (SRI). SRI creates and implements research agendas that focus on building Semada’s distributed ledger core and corresponding economic infrastructure.
