Rise of Web3 Developers

By Aduragbemi Omiyale

A Swiss non-profit organisation, Hashgraph Association, has launched the Hedera Africa Hackathon 2025 to empower the next generation of web developers and drive economic inclusion in Africa with a digital future for all.

The group is offering $1 million prize for the winning project, with applicants to develop blockchain/distributed ledger technology (DLT)-based, scalable solutions tailored to the continent’s most urgent challenges and needs.

All solutions will be built on the Hedera network – the world’s most energy-efficient and cost-effective DLT, which offers cost predictability, the highest levels of security, and the ability to support reliable, scalable, and enterprise-grade applications.

This web3 hackathon initiative combines online participation with onsite events in over 20 African cities, with a goal of attracting over 10,000 participants across more than 15 countries on the African continent.

Developers, students, and entrepreneurs are invited to collaborate to build decentralized solutions on Hedera across industries such as Finance, Healthcare, Telecoms, Sustainability, Agriculture, and Manufacturing, while leveraging the convergence of other deep technologies such as AI, IoT, Robotics, and Quantum Computing.

The hackathon aims to catalyze continuous innovation across four key tracks: On-Chain Finance and Real-World Asset (RWA) Tokenisation; ESG Sustainability and Traceability; Self-Sovereign Identity (SSI)  and AI; and Gaming, Metaverse, & NFTs.

Developers of all skill levels and backgrounds are encouraged to participate — no prior blockchain experience is required. Extensive training resources will be provided through the Hedera Academy, with access to a thriving developer community.

The Hashgraph Association and the Exponential Science Foundation will be carrying out awareness and training campaigns to prepare participants for the hackathon before the official start date on August 1, 2025. Entries will close on September 30, 2025.

“Africa is home to one of the youngest, most enthusiastic and dynamic tech communities in the world; its future will depend on digitization.

“By equipping developers and entrepreneurs with Web3 skills and next generation toolkits, we’re not just solving today’s problems, we’re shaping the future of decentralized innovation in one of the world’s most significant growth markets, fostering a digital future for all through financial, identity, and communication inclusion,” the President of The Hashgraph Association, Kamal Youssefi, said.

On his part, the co-founder and chairman of Exponential Science Foundation, Mr Paolo Tasca, said, “We encourage anyone with an interest in blockchain technology to sign up and start developing the next wave of practical solutions across multiple industries to gain valuable experience and a chance to claim the prize pool. Our hope is that participants will go on to launch their own ventures and share their learnings.”

Secure Electronic Technology

By Aduragbemi Omiyale

One of the players in the Nigerian gaming industry, Secure Electronic Technology (SET) Plc, has appointed Ms Leticia Otomewo as its acting secretary.

This followed the expiration of the company’s service contract with the former occupier of the seat, Ms Irene Attoe, on January 31, 2026.

A statement to the Nigerian Exchange (NGX) Limited on Thursday said Ms Otomewo would remain the organisation’s scribe in an acting capacity, pending the ratification and appointment of a substantive company secretary at the next board meeting.

She was described in the notice signed by the Managing Director of the firm, Mr Oyeyemi Olusoji, as “a results-driven executive with 22 years of experience in driving business growth, leading high-performing teams, and delivering innovative solutions.”

The acting secretary is also said to be “a collaborative leader with a passion for mentoring and developing talent.”

“The company assures the investing public that all Company Secretariat responsibilities and regulatory obligations will continue to be discharged in full compliance with the Companies and Allied Matters Act, applicable regulations, and the Nigerian Exchange Limited Listing Rules,” the disclosure assured.

Meanwhile, the board thanked Ms Attoe “for professionalism and contributions to the Company during the period of her engagement and wishes her well in her future endeavours.”

Russia Blocks WhatsApp Messaging Service

WhatsApp Self Messaging Feature

By Adedapo Adesanya

The Russian government on Thursday confirmed it has blocked the WhatsApp messaging service, as it moves to further control information flow in the country.

It urged Russians to use a new state-backed platform called Max instead of the Meta-owned service.

WhatsApp issued a statement earlier saying Russia had attempted to “fully block” its messaging service in the country to force people toward Max, which it described as a “surveillance app.”

“Today the Russian government attempted to fully block WhatsApp in an effort to drive people to a state-owned surveillance app,” WhatsApp posted on social media platform X.

“Trying to isolate over 100 million users from private and secure communication is a backwards step and can only lead to less safety for people in Russia,” it said, adding: “We continue to do everything we can to keep users connected.”

Russia’s latest move against social media platforms and messaging services like WhatsApp, Signal and Telegram comes amid a wider attempt to drive users toward domestic and more easily controlled and monitored services, such as Max.

Russia’s telecoms watchdog, Roskomnadzor, has accused messaging apps Telegram and WhatsApp of failing to comply with Russian legislation requiring companies to store Russian users’ data inside the country, and of failing to introduce measures to stop their platforms from being used for allegedly criminal or terrorist purposes.

It has used this as a basis for slowing down or blocking their operations, with restrictions coming into force since last year.

For Telegram, it may be next, but so far the Russian government has been admittedly slowing down its operations “due to the fact that the company isn’t complying with the requirements of Russian legislation.”

The chat service, founded by Russian developers but headquartered in Dubai, has been a principal target for Roskomnadzor’s scrutiny and increasing restrictions, with users reporting sluggish performance on the app since January.

Nigerian AI Startup Decide Ranks Fourth Globally for Spreadsheet Accuracy

Nigerian AI Startup Decide

By Adedapo Adesanya

Nigerian startup, Decide, has emerged as the fourth most accurate Artificial Intelligence (AI) agent for spreadsheet tasks globally, according to results from SpreadsheetBench, a widely referenced benchmark for evaluating AI performance on real-world spreadsheet problems.

According to the founder, Mr Abiodun Adetona, the ranking places Decide alongside well-funded global AI startups, including Microsoft, OpenAI, and Anthropic.

Mr Adetona, an ex-Flutterwave developer, also revealed that Decide now has over 3,000 users, including some who are paying customers, a signal to the ability of the startup to scale in the near future.

SpreadsheetBench is a comprehensive evaluation framework designed to push Large Language Models (LLMs) to their limits in understanding and manipulating spreadsheet data. While many benchmarks focus on simple table QA, SpreadsheetBench treats a spreadsheet as a complex ecosystem involving spatial layouts, formulas, and multi-step reasoning. So far, only three agents rank higher than Decide, namely Nobie Agent, Shortcut.ai, and Qingqiu Agent.

Mr Adetona said SpreadsheetBench measures how well AI agents can handle practical spreadsheet tasks such as writing formulas, cleaning messy data, working across multiple sheets, and reasoning through complex Excel workflows. Decide recorded an 82.5% accuracy score, solving 330 out of 400 verified tasks.

“The result reflects sustained investment in applied research, product iteration, and learning from real-world spreadsheet workloads across a wide range of use cases,” Mr Adetona told Business Post.

For Mr Adetona, who built Decide out of frustration with how much time professionals spend manually cleaning data, debugging formulas, and moving between sheets, “This milestone highlights how focused engineering and domain-specific AI development can deliver frontier-level performance outside of large research organisations. By concentrating on practical business data problems and building systems grounded in real user environments, we believe smaller teams can contribute meaningfully to advancing applied AI.”

“For Decide, this is a foundation for continued progress in intelligent spreadsheet and analytics automation,” he added.
