This guy just turned a normal run into a real-life video game against himself.
He built a web app for Meta Ray-Ban Display glasses, imported a previous GPX from Strava, and added game mechanics on top.
Now he races against himself from his past run, collecting coins, hitting sprint zones and tracking a live leaderboard through the lens.
No race buddy. Just him versus the version of him that refused to slow down.

Eu podia morar em qualquer lugar do mundo...
Nova York. Miami. Lisboa. Dubai.
Escolhi o Brasil 🇧🇷 Moro em Florianópolis.
Passei os últimos 12 anos indo e voltando entre os Estados Unidos e o Brasil. Cada vez que voltava pros EUA, a contagem regressiva pra voltar começava no aeroporto.
Aqui eu janto com amigos às 22h numa terça-feira e ninguém olha o relógio.
Aqui o desconhecido no elevador puxa conversa de verdade, não só "how are you" com resposta automática.
Aqui o churrasquinho de calçada às 18h com um guaraná gelado tem mais qualidade de vida do que qualquer restaurante de US$200 em Manhattan.
Aqui eu saio de casa de chinelo, tomo um café na padaria da esquina, e volto caminhando pela mar.
Aqui a natureza não é um parque que você visita no fim de semana. É a sua vida. Praia, montanha, trilha, cachoeira... tudo a 20 minutos.
Nos Estados Unidos, as pessoas vivem pra trabalhar. Aqui, as pessoas trabalham pra viver. E ninguém pede desculpa por isso.
O Brasil tem seus problemas. Eu sei. Eu vivo eles todo dia.
Mas nenhum problema apaga o fato de que as pessoas aqui sabem viver. Sabem rir. Sabem acolher. Sabem transformar qualquer momento num momento bom.
Isso não se compra. Não se exporta. Não se replica.
É por isso que eu estou aqui.

Most crypto "investors" are just staring at the paint job. The real money looks at the engine block. 🧠
🏎️ Solana: Hitting 300mph but the wheels fall off every 100 miles. (Reboot needed).
🚜 Ethereum: Reliable 1985 diesel tractor. It gets there eventually, but costs a fortune in gas fees.
🚅 Polkadot (Sassafras): A frictionless Maglev train running in a perfect vacuum at Mach 1.
Level up your tech thesis. The future is deterministically fast.

CBDCs and stablecoins are paving two very different paths for digital money.
And rarely do you hear anyone explain the differences between them as clearly as tE (Takemiya) āpt (Makoto) (Y 5 ) SORAMITSU | 2016-2025) did in his Unplugged take.

Hi, General🫡 I'm dedicating myself for CBDC, stablecoins, and bonds, not crypto nor DeFi project. However, if we can issue the native stable coin on the chain of SORA, that would increase the liquidity on the chain and push the price of XOR.
Solomon Islands — Bokolo Cash
In November 2023, the Central Bank of Solomon Islands initiated a PoC for Bokolo Cash, a digital Solomon Island Dollar on a permissioned Hyperledger Iroha 2 network. The PoC covered retail transactions in Honiara, interbank settlement, and simulated cross-border remittances. Participants used Fearless Wallet with two-tier KYC, and the system interoperated with the public SORA network to simulate cross-border flows—a dual-layer approach (permissioned + public) designed to combine regulatory assurance with global reach.
This is a clean example of Iroha 2 as the regulated core with interoperability to public rails when appropriate—exactly the kind of architecture central banks are exploring for cross-border use cases.
Five years in, Bakong has quietly reset how Cambodia pays. The National Bank of Cambodia’s mid-year 2025 report shows 303 million transactions in Khmer riel and 240 million in US dollars in the first half of 2025—roughly double the volumes in the same period of 2024. Total value reached KHR 129 trillion (about US $32 billion) in riel and about US $69 billion in dollars.
Built on the open-source Hyperledger Iroha (@hl_iroha) platform, Bakong has run reliably, kept improving, and continues to connect with more regional and international systems for simple cross-border payments. The last two years in particular have seen remarkable acceleration, showing how robust, modular infrastructure can scale without disruption.

Papua New Guinea — Digital Kina
From December 2024 to January 2025, the Bank of Papua New Guinea ran a CBDC PoC for Digital Kina, developed with SORAMITSU and supported by Japan’s METI, Mitsubishi Research Institute, and JICA. The PoC used the SORA v3 Hub Chain powered by Hyperledger Iroha 2, enabling participants to execute real-time P2P payments and remittances via a mobile wallet. Security features for fund recovery in case of theft or loss were tested; the trial demonstrated 24/7 secure payments and fast settlement and is slated to expand for broader feedback and regulatory refinement.
This shows Iroha 2’s fit for a national retail context and its ability to support always-on operations—critical for Pacific economies with geographic dispersion and financial inclusion priorities.

Interoperability for the real world
Bokolo Cash, Digital Kina, and DLak PoCs demonstrate architectures that align with the LFDT CBDC eBook’s broader thesis: open, modular DLTs should support domestic policy controls while enabling cross-border connectivity. The SORA v3 Hub Chain, built on Iroha 2, is designed to be that neutral bridge layer for future cross-jurisdiction flows and asset tokenization.
Figure: Example of interoperability between systems built with Hyperledger Iroha 2, leveraging the SORA v3 Hub Chain technology, a Hyperledger Iroha 2–based network, that in the future may provide an optional transaction layer between permissioned and public blockchain networks while preserving complete monetary sovereignty for each participant.
"This morning's Nikkei newspaper featured an article on the front page about Bakong, the blockchain-based digital payment system we developed for Cambodia. Transactions are booming, exceeding three times Cambodia's GDP. We are now expanding CBDC to six countries including Pakistan, Papua New Guinea, and the Solomon Islands!"
今朝の日経新聞１面に、当社が開発したカンボジアのブロックチェーンベースのデジタル決済システム・バコンの記事が掲載されました。決済金額はカンボジアのGDPの3倍を超えるなど絶好調です。パキスタンやパプアニューギニア、ソロモン諸島などに6カ国にCBDCを横展開中です！

"Cambodia was the first country in the world to introduce a central bank digital currency (CBDC) called "Bakong," realizing a cashless society. KHQR is the payment code for Bakong."

"This morning's Nikkei also featured an article on Cambodia's Bakong. It's an excellent piece that clearly conveys the thoughts of the Governor of the National Bank of Cambodia. It effectively illustrates how Bakong has transformed the lives of Cambodian citizens and played a crucial role in monetary policy."
今朝も日経にカンボジアのバコンの記事が出ました。カンボジア中銀総裁のお考えがよく理解出来る素晴らしい記事ですね。バコンが如何にカンボジアの国民の生活を変えてきたか、金融政策に重要な役割を果たしてきたかよくわかります。
