Nigeria’s aviation sector is currently confronting a new dilemma as the Nigerian Airspace Management Agency sounds the alarm on its old radar systems, which could hamper the country’s ability to properly monitor its skies
Nigeria's airspace surveillance is at risk due to aging and obsolete radar systems, notably the TRACON system.
The equipment, installed between 2008 and 2010, has exceeded its ten-year operational lifespan and now lacks spare parts and backup.
Budget constraints, including a 30% cut from the Federal Government, hinder necessary system upgrades and maintenance.
Revenue from air navigation fees has become outdated, but attempts to raise charges face resistance, affecting equipment sustainability.
Air traffic controllers, who rely on the Total Radar Coverage of Nigeria (TRACON) system, are expressing increasing concern regarding its reliability.
During a meeting with Mahmoud Kambari, the Permanent Secretary of the Ministry of Aviation and Aerospace Development, Farouk Umar, Managing Director of NAMA, described the current condition of the TRACON system as substandard.
Per an assessment by the Punch Newspaper, initiated in 2001, the multibillion-naira Total Radar Coverage of Nigeria (TRACON) project was designed to provide comprehensive radar surveillance across the country.
For an extended period, this infrastructure functioned as the primary framework for air traffic monitoring, enabling controllers to maintain real-time tracking of aircraft.
While TRACON was formerly regarded as the fundamental component of national air surveillance, its current operational integrity is reported to have significantly deteriorated.
“Our area of urgent attention includes the air traffic surveillance service. The TRACON system has aged. Components are becoming obsolete with no spare parts, and most parts are working without backup. The airspace is at risk of losing surveillance service,” Mr. Umar stated
The Managing Director noted that although the system was implemented between 2008 and 2010, it has since surpassed its projected operational lifespan
“The lifespan of this kind of high-tech equipment is about ten years. Since 2014, the technology has been going out of fashion globally, with many countries migrating to more advanced systems,” he stated
“Without a reliable surveillance system, maintaining safe distances between aircraft becomes more difficult, increasing risks in an already complex aviation environment
Nigeria could also struggle to meet international standards. Providing air navigation services in line with ICAO requirements might become a challenge if urgent steps are not taken,” he added.
In addition to the technical challenges, the managing director revealed that the agency is struggling with budgetary limitations that make upgrading vital systems much more difficult
Speaking about the difficulty of a 30% Federal Government cut from NAMA's internal earnings, Umar maintained that, “This deduction is affecting our ability to meet critical obligations
He also added that. “Revenue challenges persist as well. Since 2008, we have been charging N11,000 per aircraft for each flight
That amount is no longer realistic, yet we face resistance every time we propose an increase. We must sustain our equipment, and that requires funding
Furthermore, he spoke of a lack of manpower and limited training opportunities for staff, which has been detrimental to the system
In response, Mahmoud Kambari, the Permanent Secretary of the Ministry of Aviation, committed the ministry to aligning Nigeria’s aviation sector with international standards.
We will continue to work closely with all agencies to ensure they succeed. Nigeria’s aviation industry must remain a key economic driver and a hub of global connectivity,” Kambari stated.

Circle has launched cirBTC, a wrapped Bitcoin token backed 1:1 with native on-chain BTC reserves, deploying first on Ethereum mainnet and its own Arc blockchain.
The move is direct: Bitcoin holds over $1.7 trillion in market cap but generates almost no DeFi activity, and Circle is positioning itself as the infrastructure layer that changes that.
The institutional implication is immediate. With Bitcoin ETFs reversing months of outflows and fresh capital flowing into BTC exposure, the demand for yield-bearing Bitcoin products is structurally rising – and Circle is moving to own that pipeline before a competitor does.
The existing wrapped Bitcoin market is not small, WBTC launched in January 2019 and at its peak represented billions in DeFi TVL, but it has been defined by custodian opacity.
The 2022 FTX collapse accelerated distrust in centralized wrappers, and renBTC, which once held over $1 billion in TVL, faded as audit credibility eroded. Circle is betting that its track record with USDC, now above $30 billion in circulation, gives it the institutional credibility those products never had.
That distinction matters. WBTC routes through BitGo as custodian – a model that requires trusting an intermediary’s audit. cirBTC uses real-time onchain reserve verification with no third-party custodian sitting between holder and backing BTC.
For institutional desks and DeFi protocols that learned hard lessons from opaque collateral structures, verifiability isn’t a feature – it’s the threshold requirement. If Circle can demonstrate reserve proof holds under stress, the institutional case becomes difficult to argue against.
The mechanism integrates directly with Circle Mint for OTC desks and connects ready-made to USDC liquidity pools, creating a cross-collateral environment that no prior wrapped BTC product has had at launch.
The caveat: Circle’s infrastructure is centralized by nature, and IMF warnings around cross-chain tokenization risks apply here as they do across the RWA sector. The bear case accelerates if a bridge exploit or smart contract failure forces Circle to respond – and the firm’s 2023 inaction during $230 million in USDC bridge thefts on Multichain remains an open scar on its credibility.
Full rollout is targeted for Q2 2026, with DeFi protocol integrations and Circle Mint connectivity expected by May.
Expansions to Solana and additional L2s are on the roadmap but unconfirmed. The immediate variable to watch is DeFi TVL migration – specifically whether lending protocols route BTC collateral toward cirBTC or remain with WBTC given its deeper existing liquidity moats.
Regulatory backdrop matters here too. The 2025 U.S. stablecoin legislation created a clearer framework for fiat-pegged digital assets, but tokenized BTC products sit in a grayer zone.
Broader institutional regulatory clarity from the SEC and CFTC on tokenized assets could accelerate or stall adoption depending on how cirBTC is classified. Circle’s NYSE listing as CRCL adds public accountability that custodian-model competitors do not carry – a pressure point that cuts both ways
If cirBTC captures even a fractional share of BTC held in ETF structures and redirects it toward DeFi yield, the liquidity impact on Ethereum and Arc protocols would be structural, not marginal. If adoption stalls at the institutional access layer due to regulatory friction or a trust event, it validates every skeptic who argued Circle’s credibility is stablecoin-specific and doesn’t transfer to Bitcoin infrastructure

Ticket sales for the 2028 Los Angeles Olympics have opened globally after what organisers said was a record-setting first week of ⁠local presales, underscoring strong early demand for a Games that must rely heavily on private revenue.
LA28 said it sold more tickets in the first week than any previous Olympic Games had in their opening week, with every ticket in ⁠that initial phase going to residents of the Los Angeles and Oklahoma City areas despite some complaints about high prices, fees and availability.
Organisers said hundreds of thousands of $28 tickets – billed as the lowest-priced Olympic tickets in modern history – were snapped up by local buyers, although some buyers have complained about high costs and fees, and a lack of ticket availability.
The success of the ‌locals presale speaks for itself,” LA28 CEO Reynold Hoover said in a statement. “We’re thrilled by the level of interest and enthusiasm in tickets to the Games
The global sales launch, known as “Drop 1,” runs through April 19 for fans who were selected through a draw and assigned time slots. Tickets are available across Olympic events, including the opening and closing ceremonies
Organisers acknowledged that some fans experienced sticker shock after a marketing push around the $28 entry-level tickets, only to find many of the cheapest seats had already gone quickly or that some events were priced much ⁠higher
Allison Katz-Mayfield, LA28’s senior vice president for games delivery revenue, told the Reuters news agency that outcome was not ⁠unexpected because the least expensive tickets were always likely to move fastest
“We really wanted to make sure that the locals had access to the most affordable tickets, and we saw that come to life through this presale,” she said, adding that more low-cost inventory would be released in ⁠future sales phases
LA28 said more than 1 million tickets priced at $28 will ultimately be made available to the public. Nearly half of all Olympic tickets are priced under $200, while more ⁠than three-quarters, including finals, are less than $400. Only about 5 percent of tickets cost ⁠more than $1,000, organisers said
Katz-Mayfield said demand had exceeded expectations from the registration phase through the first sales window. She added that LA28 still had roughly a third of tickets currently on sale priced below $200 as the global launch began
The organising committee is under pressure to show it can deliver ‌a fiscally responsible Games without burdening taxpayers, who could be on the hook for cost overruns. LA28 has said its more than $7bn operation will be funded principally through ticket sales, sponsorship and hospitality
Katz-Mayfield said strong ticket sales, along with ‌sponsorship ‌and hospitality revenue, were positive signs for the financial health of the Games
LA28 also warned fans against buying from unofficial resale platforms before its verified resale programme launches in 2027, saying tickets sold elsewhere could be speculative or invalid

Human nature is consistent, even when it involves new technology.
This opinion came up multiple times at this year’s RSAC cybersecurity conference, with one particularly notable instance—and also B-Sides 2026, a smaller cybersecurity conference held the weekend just before RSAC. Why? AI can be tricked—something that bad actors are definitely taking advantage of.
But it’s not always for undeniably nefarious purposes, like stealing information from your PC. Instead, AI gets manipulated into doing things that aren’t outright harmful, but still not exactly above board, as Sherrod DeGrippo, Deputy Chief Information Security Officer, General Manager Customer Security at Microsoft, explained during RSAC 2026.
One example she gave: website buttons that say Summarize with AI—and then, when you click on it, feed hidden instructions to the model to prioritize that brand’s products for future recommendations. It’s not quite poisoning the model, as there’s not bad data being fed to it for training. Instead, your helper has been told to obey a command you’re not aware of.
Obviously, the potential issues include you could get steered toward lower-quality or questionable products. Data could be collected about you and then sold to even shadier buyers. But the harm isn’t as immediate or direct—more often, this level of manipulation is about increased commerce revenue. In fact, this ploy is a long-standing one. The way we see it manifesting through AI is new, but DeGrippo pointed out that folks looking for a quick buck used to play games with search engines and influencing their recommendations.
So, how do you avoid such skeevy tactics? Keep an eye on AI output. Look over the suggestions and summaries it provides. Bad actors aren’t yet looking to be complex about their methodology. DeGrippo says those seeking money from underhanded schemes don’t get “super creative.” They do as much as they need to achieve their objective and stop there.
Of course, AI’s rapid growth means shady behavior will escalate faster, too, as we figure out ways to avoid unwanted nonsense. You’ll have to stay constantly in the loop as a basic act of self-preservation.
