Tanssi and C9 Tech Collaborate to Launch Brazil’s First Municipal Blockchain Currency

The Tanssi appchain infrastructure protocol is excited to announce a collaboration with C9 Tech to launch Brazil’s first municipal currency on blockchain technology for the municipality of Santo Antônio da Alegria. This revolutionary project, developed with the support of ICT Inova Brasil and the Brazilian Association of Municipalities (ABM), promises to transform the management of social benefits, establishing a new standard of efficiency, transparency, and financial inclusion.

"This technology we are implementing may be, in recent years, one of the best social support initiatives for truly aiding in resource distribution with cost reduction. It is Web3 technology solving a real problem and providing freedom and agility in resource delivery," says Wagner Nunes, C9 Tech CTO.

C9 Tech: Making Blockchain Accessible for Everyday Use in Brazil

C9, a startup from Brazil founded in 2021, aims to simplify how regular users and businesses connect to Web3 virtual currencies. They are changing how people and organizations handle blockchain transactions by making virtual assets accessible through both physical and digital solutions in a way that is easy, fast, and secure.

C9 Tech also provides comprehensive solutions for both newcomers and experienced blockchain users. Their services include blockchain document registration, asset tokenization, online wallets, and integrations with POS and ERP systems.

As part of this historical project, the C9 team, in collaboration with Tanssi, will develop the C9 Platform. They are introducing the social token 'Alegria' (meaning 'happiness' in English) for the municipality of Santo Antônio da Alegria, Brazil. This system will use POS machines or NFC-enabled smartphones for businesses alongside a physical card containing a web3 wallet for users. This approach is cost-effective and familiar to most of the local population, ensuring easier adoption with minimal friction.

This innovation eliminates the need for banks, acquirers, and other intermediaries in the payment chain, making the payment solution more accessible and affordable to everyday people. It also simplifies the process of receiving benefits, which helps to boost the local economy by keeping money circulating within the community. Additionally, it enhances trust in public administrations.

Tanssi x C9: Bringing Customizable Appchains To Municipalities

As government offices begin to integrate blockchain technology, they may encounter challenges like high transaction costs, slow processing times, and security risks that threaten the integrity of sensitive municipal data. C9 aims to address these issues by deploying multiple appchains for municipalities on Tanssi. This approach offers unparalleled control over privacy, customization options, cost reduction, and operational flexibility for their blockchain applications. Tanssi’s protocol uniquely provides these features, ensuring a future benefit for municipalities.

Deploying an appchain typically involves a maze of infrastructure complexities, requiring significant resources in terms of money, manpower, and time. Tanssi simplifies this process for projects like C9, enabling the effortless deployment of appchains through the Tanssi dapp. Equipped with the right tools and services, developers can quickly launch and manage their appchains. This includes block production as a service, enhanced data retrievability, and seamless cross-chain connections. Consequently, projects like C9 can concentrate on what truly matters: delivering a secure and superior experience to users. Moreover, the swift deployment of appchains also translates into a faster time to market, maximizing impact and efficiency.

Here are the key advantages of these organizations having their own appchain:

Full Control Over Applications

Appchains empower municipalities and other entities with full autonomy over their applications. This allows tailored blockchain customization to meet specific needs, free from shared network constraints. This control is crucial for municipalities to enforce governance rules, privacy safeguards, and operational protocols aligned with their requirements.

Wallet Whitelisting

An important benefit of municipalities having their own appchain is the capability to whitelist wallets. This feature allows them to manage access to their own blockchain ecosystem, ensuring that only trusted entities or approved users can deploy contracts or engage with the chain. This functionality is critical for maintaining security and regulatory compliance within the municipality's jurisdiction.

Gasless Customization

The ability to configure the appchain to operate as a gasless chain is an important advantage. Gas fees often pose a substantial barrier to entry for users and developers on public blockchains. By removing or subsidizing gas fees within their appchain, municipalities can promote broader adoption and utilization of blockchain applications, eliminating financial obstacles.

Decentralized Infrastructure

Appchains provide full control and customization while leveraging decentralized blockchain technology. This allows municipalities to benefit from blockchain's built-in security, transparency, and resilience without starting from scratch. It also ensures compatibility with other blockchain networks, making their applications more scalable and user-friendly.

Future Outlook

C9 Tech's next goal is to expand their solution to more towns and cities. Municipalities have diverse needs across their departments, making it crucial to protect data and comply with regulations. Varying levels of tech skills and resources can also complicate the launch and maintenance of community-serving apps. The project will begin by issuing meal vouchers for employees of the Municipality of Santo Antônio da Alegria, with plans to eventually include social benefits for all residents. Looking ahead, C9 plans to create an appchain on Tanssi for each new municipality involved. This approach will enhance data security, streamline operations, and improve financial accessibility.
