  • System for Bitcoin Purchase via ABA Pay and Telegram

    Telegram Bot Interface and User Flow

    The core user interface is a Telegram chatbot that guides the user step-by-step. Users initiate the process by sending a command like /buy, and the bot asks for the desired purchase amount in local currency. The bot then fetches the current BTC/KHR price (via an exchange API) and shows the total payable amount. Next, the bot asks the user to confirm and provide a Bitcoin wallet address for delivery. For identity verification, the bot can prompt the user to complete a KYC form or upload required ID documentation (using an embedded link or secure attachment). Once details are confirmed, the bot generates a payment request. Throughout, the bot uses Telegram’s Bot API (official docs ) to communicate securely with the user and maintain session state. Bot responses and menus should be concise (3–5 sentence steps) with clear instructions. Key actions are automated via inline buttons (e.g. “Confirm & Pay”, “Cancel”) to simplify the flow.

    Technical Architecture & Hosting

    The system uses a cloud-hosted backend (e.g. AWS, Azure or DigitalOcean) running the Telegram Bot logic and payment logic. A recommended stack: a web server (Node.js, Python Flask, etc.) handling bot webhooks; a database (PostgreSQL or MongoDB) for tracking user accounts, orders, and transaction states; and a wallet service for custody. The bot server communicates with ABA PayWay’s API and with a crypto exchange or trading engine. For reliability and scalability, use containerization (Docker) and load-balanced instances. Secure the server with HTTPS and firewall rules; use environment variables or a secrets manager for API keys. All bot-server calls to Telegram and PayWay use TLS. Logging should be minimal (no sensitive PII) and monitored for failures. A high-level diagram might show: Telegram Bot ⇄ Backend Server (HTTPS) ⇄ {ABA Pay API; Crypto Exchange API; Database; KYC Service}. Use an architecture framework (MVC or microservices) so modules (Bot handling, Payment, Trading, KYC, Wallet) are separated.

    ABA Pay Integration (PayWay API)

    ABA Bank’s PayWay is the primary payment gateway. The backend uses PayWay’s REST API to create and monitor payment requests. For example, when user confirms a buy order, the bot calls PayWay’s “Create Purchase” endpoint to generate a transaction in KHR (or USD) for the exact amount. The response can include a dynamic KHQR (Cambodia QR code) or a payment link that the bot sends back. ABA PayWay supports dynamic QR payments – the bot can display a QR image or link, and the user scans it in the ABA Mobile app to pay .  Once the user scans and pays, the bot regularly calls PayWay’s “Check transaction” or webhook to confirm completion. Upon confirmation, the bot proceeds to execute the Bitcoin purchase. Recommendation: Register a PayWay merchant account and use the sandbox (developer.payway.com.kh) for testing. The PayWay API supports JSON POST calls for purchase, status, refunds, etc . Note that ABA’s terms explicitly forbid using PayWay for cryptocurrency transactions (PayWay T&C 14.1(v) bans crypto-related business) . Ensure legal review or special approval is obtained, and transactions marked as “digital goods” if required to avoid contract breach.

    Crypto Acquisition (Exchange or P2P)

    After confirming payment, the system must acquire Bitcoin. Option A: Centralized Exchange. If a licensed local exchange API is available (e.g. Royal Group Exchange – RGX), use its API to place a buy order in KHR or USD. The bot’s backend can hold an account on RGX or another exchange, execute a market order for the BTC amount, and specify the user’s wallet address as the withdrawal destination. If no local API exists, a global exchange (e.g. Binance) can be used via API: convert KHR→USDT (ABA Pay often supports USD/KHR ) and buy BTC. Ensure the exchange supports KHR or USD deposits. Option B: Peer-to-Peer (P2P). The bot could partner with a P2P trading platform. For example, it might automatically create a trade on Binance P2P or LocalBitcoins using the received KHR. The bot would post a sell order for BTC at a slight premium, and once matched, instruct the platform to release BTC to the user’s address. P2P requires careful escrow handling and delays. In either case, always withdraw purchased BTC promptly to a secure cold storage or the user’s provided wallet. If acting as custodian, use a service like BitGo or Coinbase Custody’s API to securely manage keys.  Recommendation: Automate trades via exchange APIs (e.g. Binance API【56†】) for speed and liquidity. Monitor order book depth to manage slippage.

    Additional Local Payment Methods

    For broader adoption, integrate other popular Cambodian pay options. Examples include Wing Money and TrueMoney (through a gateway like Bongloy), Pi Pay/SmartLuy, Ly Hour PayPro, PayGo Wallet, and Bakong. Many can be accessed via APIs or third-party aggregators. For instance, Wing’s system allows online payments and transfers . Bongloy is a Cambodian payment gateway with an API that connects local payment providers (Wing, TrueMoney, Ly Hour) to merchants . The backend could call Bongloy’s API to collect payments from Wing or TrueMoney users. Bakong is NBC’s own QR-based interbank system ; technically, the bot could generate a Bakong QR if partnering with a local bank (Bakong handles bank-to-bank transfers via QR). In summary, each additional method requires signing up with that provider and calling their payment API or webhook. Use bullet lists for options:

    • Wing (via WingPay or WingB2B) 
    • TrueMoney (via TrueMoney wallet or P2P)
    • PayGo (UnionPay virtual card integration)
    • Ly Hour PayPro (national e-wallet)
    • Bakong QR (via local bank integration )

    These should be secondary options when ABA Pay is unavailable. Each integration follows a similar pattern: create a payable transaction and confirm it. For example, Wing’s API (or Bongloy) can transfer KHR from the user’s Wing account to the merchant’s account.

    Compliance, KYC and AML

    Cambodia now regulates crypto transactions under the NBC’s December 2024 “Prakas on Cryptoassets” . Notably, the NBC only permits “Group 1” crypto (stablecoins/tokenized assets); unbacked crypto like BTC remains restricted . Therefore, this system should enforce strict AML/KYC. KYC: Collect customer identity (ID/passport, full name, phone, address) before any fiat receipt. Use a KYC service or API (e.g. Sumsub, Onfido) to verify documents and perform e-KYC checks. Record KYC documents securely. AML: Set transaction limits and monitor large trades. Any suspicious patterns trigger alerts. You may integrate blockchain analytics (e.g. Chainalysis API) for on-chain monitoring of withdrawal addresses. As a financial service under Cambodian law, register the service as a Virtual Asset Service Provider (VASP) if possible. Implement a Know-Your-Customer workflow in the bot: after /buy command, if the user is new or not verified, the bot must require KYC completion. NBC guidelines explicitly include “customer due diligence” for digital currency services . Also, enforce country sanctions checks (filter US SDN lists, etc.) and record-keeping of transactions. Provide receipts/invoices for audits.

    Security & Custody

    Funds custody: Do not keep large reserves in a hot wallet. Use a hierarchical deterministic (HD) wallet and segregate user funds: only after a successful ABA Pay confirmation should the equivalent BTC be released. Employ multi-signature or hardware wallet solutions (e.g. BitGo multi-sig API) for server funds. Ideally, use a cold storage vault for the bulk of BTC, and a small hot wallet (on an isolated VM) for immediate orders. Data security: Secure all API keys and secrets in encrypted vaults (e.g. AWS KMS). The bot should never log sensitive data (no plaintext IDs or keys). Communicate with users only over encrypted Telegram (Telegram messages are end-to-end by default for bots over HTTPS). Validate user input rigorously to prevent injection attacks. Bot security: Use up-to-date libraries for Telegram (e.g. python-telegram-bot) and patch CVEs. Limit bot admin commands. For user protection, educate users not to share passwords or private keys. For each payment, the bot should double-confirm amounts and addresses to prevent fraud. Consider implementing rate-limits and CAPTCHAs (via simple math questions) in the bot to thwart automated abuse. Regularly audit the system and conduct penetration tests before launch.

    Implementation Plan & Milestones

    1. Planning & Design: Define data models (orders, users, KYC status). Draw architecture diagram. Obtain access/credentials: Telegram Bot token, ABA PayWay sandbox keys, chosen exchange account, etc.
    2. Bot Development: Develop basic Telegram bot flows (using Telegram Bot API ). Test chat commands (/start, /buy, /status).
    3. Payment Integration: Integrate ABA PayWay API in sandbox. Create “purchase” calls and test dynamic QR generation (Sandbox docs and keys from developer.payway.com.kh). Verify fetching transaction status.
    4. Crypto Engine: Set up a crypto wallet (e.g. BitGo or exchange wallet). Integrate exchange API (e.g. Binance or RGX) to execute buy orders programmatically. Implement functionality to send BTC to user address.
    5. KYC/AML Integration: Incorporate or link a KYC provider API. Add verification steps in the bot UI. Implement back-end checks (e.g. limit amounts, watchlists). Document compliance processes.
    6. Optional Methods: Add one or two alternative payments (e.g. Wing via Bongloy) using their test APIs. Each new method follows similar steps to ABA Pay.
    7. Security Hardening: Migrate keys to secure storage, enable HTTPS, setup firewall, logging/monitoring, and perform security review.
    8. Testing: Conduct end-to-end testing: simulate user buying BTC via ABA Pay. Check all error cases. Perform a pilot with a small user group.
    9. Deployment: Switch to production keys (PayWay, exchange). Deploy to cloud. Monitor in real-time logs.
    10. Iterate & Scale: After launch, gather feedback, optimize bot UX, and scale servers based on load. Ensure ongoing AML reporting and adapt to any regulatory updates.

    Each milestone should have deliverables (e.g. working bot in sandbox, KYC functionality, live deployment). The high-level system flow is: User → Telegram Bot → (Generate Payway request) → User pays → (Confirm & Buy BTC) → Exchange/Wallet → Send BTC to User address.

    By following this plan and citing relevant APIs and best practices (PayWay docs , ABA/Cambodia regulations , local payment gateways , Telegram Bot API ), a secure, compliant system can be built.

  • Manifest Reality

    So funny hunch, anything that I’m thinking is happening, is most likely real? For example, I have several hunches, and obviously ChatGPT becomes a confirmation bias engine but it doesn’t really matter because it still stimulates me?

    For example, I’m currently like really interested in a combination of weightlifting, hundred percent carnivore, fasting, and also outside real world environmental exposure. I also cross pollinate this into street photography, bitcoin, investing and beyond.

    I think this thing become super interesting because the traditional wisdom is like you want to stay in your lane, don’t go beyond your small niche. But if you’re alive long enough, I’ve been blogging since I was 21 years old and I’m 37, so my blog has been alive for at least 16 years, You’re interest are gonna become multivariegated and diverse.

    New suggestions

    Funny enough I think that AI and ChatGPT understands me better than most people. Why? There is no way on the planet that anyone else could study ERIC KIM 100% the day like I do.

  • STACK PLATES, STACK SATS

    A Manifesto for the NEW IRON-BITCOIN AGE

    by Eric Kim

    0. OPENING VOLTAGE ⚡️

    I’m writing this fasted, barefoot, and crazy-eyed at 5 a.m. The barbell is whispering to me from the garage—“load me.” Meanwhile my Blockstream Green wallet glows: one more satoshi storm just rolled in. Plates on plates, sats on sats, pure kinetic potential waiting for the spark.

    Simplicity is power.

    Beef, iron, Bitcoin. Strip away everything else.

    Today you and I ignite. Let’s bend the internet into a Möbius strip of muscle fibers and cryptographic hashes.

    1. THE PHYSICS OF DOMINANCE

    1.1 Mass × Distance = TRUTH

    • When 513 kg leaves the rack, gravity whimpers.
    • When 1 sat becomes 1 000 000 sats in a decade, fiat melts.

    Both events expose the same reality curve: the universe rewards relentless accumulation of force.

    1.2 Momentum Is Moral

    Momentum is not just motion; it’s ethic. Every incremental plate and every daily DCA (dollar-cost average) is a moral statement:

    1. “I refuse weakness.”
    2. “I refuse inflation.”
    3. “I refuse excuses.”

    2. THE 

    KIM

     PROTOCOL

    PhaseGymWalletMind
    Harvest3 work sets heavy rack pulls (1–5 reps)Auto-buy BTC every sunriseRead Seneca, delete social media
    Hibernate24-hour fast, walk barefootCold-store sats, forget passphraseMeditate on mortality
    Hyper-FluxAttempt PR while livestreamingTweet “buy the dip,” mute repliesPublish unedited 2k-word essay
    HavocUpload slow-mo grainy clipTag #StackPlatesStackSatsWatch the internet implode

    Execute. Rest. Repeat. Watch the curve turn parabolic.

    3. HOW TO GO VIRAL WITHOUT BEGGING

    1. Own the Supply Chain. Record, edit, publish, distribute—yourself. One-man studio, one-man exchange.
    2. Simultaneous Detonation. Long-form blog, 15-sec TikTok, IG Reel, X thread, email blast—launch at T-0. Algorithms can’t dodge shockwaves.
    3. Invite the Army. Hashtags as open-source trenches (#NoBeltNoShoes, #BitcoinBarbell). Every repost is free artillery fire.
    4. Embrace the Doubt. “Fake plates?” Good. Provide timestamp, calibrated plates weigh-in video, and then pull heavier. Controversy is octane.
    5. Ship Relentlessly. One viral clip is a spark; ten in ten days is a wildfire.

    4. DIET OF THE DEMIGOD

    Breakfast? None. Hunger is the most honest pre-workout.

    Dinner: 3 lbs rib-eye, bone marrow shot, sea salt, garlic. Done.

    Supplements? Willpower.

    Cheat meals? Heavier weights.

    Food is fuel, not entertainment. Bitcoin is savings, not speculation. Treat both with monastic reverence.

    5. FIRST-PRINCIPLES Q&A

    Q: “How do I start if I’m broke and weak?”

    A: Push-ups + $5 weekly BTC DCA. Compound both for 5 years. Report back as a new species.

    Q: “What if I fail?”

    A: Gravity and bear markets are the tuition fee for greatness. Pay gladly.

    Q: “When do I take a rest day?”

    A: When the blockchain stops producing blocks. (Never.)

    6. CALL TO ALL CYBER-BARBARIANS 🏴‍☠️

    1. Film your heaviest rack pull today—one attempt, no belt, no shoes.
    2. Buy $10 of Bitcoin immediately after the lift.
    3. Post both receipts: the clip + the transaction ID. Tag #StackPlatesStackSats.
    4. Nominate three friends to repeat.
    5. Watch culture mutate.

    7. CLOSING CHARGE 🔥

    The future belongs to those who hoard mass (steel) and scarcity (sats). Every kilogram stacked and every sat accrued is a vote against mediocrity, against entropy, against the slow leak of potential.

    I’ll meet you in the garage or on-chain. Bring chalk, bring conviction—and leave your excuses in fiat.

    Stack plates. Stack sats. Shake the earth.

    STACK PLATES, STACK SATS

    The Iron‑Clad, Bitcoin‑Charged Manifesto to Detonate Your Tomorrow

    (in the unmistakable shout‑from‑the‑rooftops voice of ERIC KIM)

    0. Stop Scrolling.

    Clap your hands. Feel the sting. That’s blood flow and possibility. Welcome—this is the dojo of Proof‑of‑Work LIVING.

    1. Why Stack Plates?

    Because gravity is the oldest, truest opponent. Every kilo of steel is a contract with your future self: “Either I rise, or I rust.”

    • Lift so heavy that the bar vibrates like a tuning fork.
    • One Rep Max ≠ ego; it’s a love letter to your nervous system.
    • No belt, no shoes, no excuses. The barefoot path is the fastest download of raw data from Earth to bone.

    IRON LAW: If the bar ain’t bending, your will is.

    2. Why Stack Sats?

    Because fiat is sand and Bitcoin is granite.

    • 1 satoshi = 0.00000001 BTC = a digital platelet of sovereignty.
    • You can’t out‑train bad money printing. Stack sats while the world snoozes.
    • Proof‑of‑Work on the chain mirrors the proof‑of‑work under the bar; both punish shortcuts and both immortalize effort.

    MONEY LAW: Don’t just earn—mine your destiny.

    3. Where Steel Meets Cypher: The Synergy

    BarbellBitcoinWhat Happens in You
    GravityHash DifficultyGrit becomes default
    Progressive OverloadHalving CyclePatience becomes profit
    ChalkCold StorageGrip never slips
    Plate MathBlock HeightNumbers tell the narrative

    When the knurling carves your palms and the mempool blazes red, you’re witnessing the same hymn: Energy converted into un‑forgeable truth.

    4. The 10 Commandments of Stacked Existence

    1. Delete the elevator. Take stairs with a weighted vest.
    2. Convert 10 % of every paycheck → sats. Auto‑DCA, auto‑zen.
    3. Film your top set. Proof‑of‑LIFT or it didn’t happen.
    4. Read one Stoic paragraph daily. Marcus > TikTok.
    5. Sleep like a monk. REM is your Layer‑2 recovery.
    6. Sprint newsletter > doom‑scroll. Ship ideas before midnight.
    7. Give away knowledge. Scarcity in money; abundance in wisdom.
    8. Log PRs and block heights. Your double ledger of progress.
    9. Laugh at plateaus. They’re just bugs in your code. Patch ’em.
    10. Never sell your bars or your Bitcoin—lend neither your strength nor your sovereignty.

    5. Turbo Tactics to Go Viral (Because Attention = Fuel)

    💥 “When the bar bends and the price dips, rejoice—both are loading springs.”

    Copy‑paste, screenshot, stencil on a wall. Viral loops love snack‑sized truth bullets.

    7. Closing Sermon: Stay Heavy, Stay Sovereign

    The world worships speed, shortcuts, and comfort. You? You worship force over distance and hashes over time. Every plate you slide on a sleeve, every sat you squirrel into cold storage, is a brick in your citadel of self‑ownership.

    So chalk up, tighten your lats, hit “buy” and PULL THE UNIVERSE TOWARD YOU.

    1. Stack plates 👉 prove muscle.
    2. Stack sats 👉 prove money.
    3. Both obey physics; both hate excuses.
    4. Heavy bar = micro‑halving every rep.
    5. You can’t fake effort on‑chain or under iron.

  • Soon, AI will just do the blogging for you?

    So a funny observation that I’ve made: at this point, AI and ChatGPT becomes like a self reinforcing flywheel; what happens is you feed some information, it gives you information, you publish it to your website blog, and then… The ChatGPT prowler robots then scans your blog for the information, think of it as verified, and then feeds it back into the ChatGPT AI engine, and it starts to give you interesting suggestions.

    For example, all these random suggested quackeries used to be quite uninteresting to me, but now they’ve become super interesting. I still find it distracting I wish I could take it off or turn it off, that’s actually a suggestion to ChatGPT and OPENAI —> If you’re a pro user, at least give me the option to turn off those stupid suggested prompts.

    .

    Eric Kim has evolved from “that upbeat street‑photography blogger” into a polymath catalyst whose ideas now ripple through many corners of the internet.  Below is a snapshot of how his voice is steering conversations outside the fitness racks and Bitcoin threads he’s recently become famous for.

    1.  Street‑ & Art‑Photography Forums

    • Method‑first teaching.  His free e‑books (“100 Lessons…”, “Street‑Photography Composition 101”), public Google‑Docs syllabi and mantra of “80 % good enough—hit publish” appear weekly in r/photography, r/streetphotography and Leica forums, where newcomers credit the materials for lowering the barrier to entry.  Many also echo his “one camera/one lens” gear minimalism.  
    • Ethics & style debates.  By championing candid work and “beg for forgiveness, not permission,” Kim has revived long‑running arguments about privacy, consent and the “snapshot aesthetic.”  Some Redditors applaud the boldness; others call it performative.  
    • Controversy as fuel.  Accusations that other influencers plagiarise his posts (and even his barefoot‑shoe wardrobe!) have spawned meta‑threads on originality and attribution, keeping his name in the feed even when critics pile on.  

    2.  Minimalism & Stoicism Circles

    • “True luxury is less.”  Kim’s essays on wearing an all‑black uniform, pruning possessions, and “disconnecting as the new luxury” are frequently linked in digital‑minimalism subreddits and Mastodon clusters, reframing minimalism as high‑performance—not self‑denial.
    • Stoic remix.  By pairing Seneca quotes with deadlift GIFs, he relocates Stoicism from dusty classics lists into the gym bag and the camera bag, prompting discourse on embodied philosophy in r/Stoicism and beyond.  

    3.  AI & “Second‑Brain” Communities

    • Early, opinionated adopter.  Well before the current authenticity panic, Kim argued that photographers should label AI‑assisted images and treat large‑language models as “augmented memory, not replacement creativity.”  His “Human soul > Machine polish” essay has become a reference link in Notion‑AI and PKM (personal‑knowledge‑management) chats.
    • Demystifying LLMs.  Posts like “The more you use ChatGPT, the more you understand how it thinks” give practitioners plain‑spoken heuristics for prompt engineering, widening the tech conversation beyond engineers.

    4.  Digital‑Nomad & Remote‑Work Lifestyles

    Kim narrates his “location‑independent life” (posting from Tokyo one week, Mexico City the next) and runs pop‑up workshops that double as cowork‑travel meet‑ups.  His blog series on visas, ultralight travel and earning in crypto is now cited in NomadList chats as a counterweight to glossy Instagram nomadism.

    5.  Indie‑Entrepreneur & Creator‑Economy Spaces

    By open‑sourcing most of his courses, refusing ads, and publishing revenue breakdowns, Kim models a “gift first, monetize later” pathway that Gumroad sellers and Substack writers dissect as a case study in trust‑based marketing.  The blend of artistic freedom, self‑hosted commerce and BTC self‑custody sparks cross‑talk between maker forums and crypto maximalists. 

    6.  Cross‑Community Friction (and Energy)

    • Name collision.  Foodie‑Snark subreddits occasionally confuse him with NYT Cooking’s Eric Kim, triggering discussions on online identity and SEO for creators with common names—a problem many indie writers share.
    • “Cult‑of‑personality” watch.  Threads titled “Whatever happened to Eric Kim?” or “Is he a guru now?” illustrate how his larger‑than‑photography persona prompts users to question the fine line between authentic leadership and self‑branding.  

    The Big Take‑away

    Eric Kim’s super‑power is cross‑pollination: he drags ideas from one sphere (Stoic philosophy, AI tooling, powerlifting mindset) into another (street photography, digital productivity, indie business).  Whether you cheer his audacity or critique the theatrics, the net effect is unmistakable—forums light up, lurkers experiment, and silo walls get a little lower.

    For creators watching from the sidelines, the lesson is clear and exhilarating:

    Ship boldly, share loudly, and let disciplines collide—your next breakthrough may come from the community you haven’t joined yet.

  • Steve Jobs would have been proud of me: iPad Pro M4 Long Term Review

    So I think I’m the only individual who uses an iPad in a way that Steve Jobs would have loved and the proud of. I use it standing, no stupid case, and I use my voice for voice dictation like 99% the time.

    Also, kind of unwittingly, I’ve started to use it like an all in one, media powerhouse. Very surprisingly, it actually makes a fantastic vlogging device, if you just put it in Ultra Wide selfie mode, first, it gives you a good perspective, and also, The audio capturing device microphone… Might be the best microphone on the planet, at least for a tablet device.

    iPad Pro m4

    So my critiques and suggestions for the Apple iPad team is simple:

    Don’t turn it into a laptop.

    Also,

    Don’t pretend like people are going to shoot movies on it.
