Catatan belajar mengelola VPS untuk menjalankan node airdrop.
-Project: DAC Quantum Chain (Testnet) -Role: Light Node Operator -Objective: Menjaga stabilitas infrastruktur node pada fase Testnet dan -mengumpulkan interaksi on-chain untuk potensi incentivized reward. -Infrastructure: VPS Ubuntu (Running via Termius). -Status: Syncing Block / Active.
-
Target Nodes: Umi Network (MoveVM), Nava Labs, & Icarus Finance.
-
Infrastructure: Contabo VPS (4 vCPU / 8GB RAM / Ubuntu 24.04).
-
Security Goal: SSH Key authentication, UFW configuration, & Wallet Isolation.
-
Infrastructure: Preparing Contabo VPS (4 vCPU / 8GB RAM).
-
Security Goal: SSH Key authentication & UFW configuration.
•Server Preparation: Melakukan update sistem (apt update) dan instalasi alat pendukung (wget, curl, screen).
•Binary Installation: Berhasil mengunduh binary node DAC versi Linux AMD64 dari repositori resmi.
•Account Creation: * Membuat wallet baru di dalam direktori node. •Berhasil mengamankan Public Address: 0x0805930f9cde3140c330c7bb8e9e696955df7f73. Security & Backup: •Berhasil melakukan backup Keystore File (format JSON) secara manual. •Mencatat password enkripsi wallet secara luring (offline). •Node Execution: * Menjalankan node menggunakan perintah ./dacnode --testnet di •dalam sesi screen agar tetap berjalan 24/7 di background. Status saat ini: Sedang mengunduh header blok (Imported new chain segment).
- Installed Aptos CLI v9.1.0 on Ubuntu 24.04.
- Created dedicated node wallet: 0x548aba46...
- Successfully compiled and published 'my_first_contract' to Umi Devnet.
- Transaction Hash: 0x8eb119e3a28826101cbd7f8fbf935a37c1fc6c5d17d2aba318e9f89e6387?network=devnet
[x] Login Success: Accessed Contabo VPS via Termius. [x] System Maintenance: Performed apt update & upgrade. [x] Environment: Installed basic tools (screen, git, curl). [ ] Next: Configuring Umi Network Node components.
- Selected VPS Specs: 4 vCPU, 8 GB RAM, 75 GB NVMe (Optimized for node speed).
- [!] Issue: Encountered "a.trim is not a function" system error on Contabo during Bank Jago payment integration.
- Action Plan: Switch to PayPal as a payment gateway to bypass direct card processing errors.
- ✅ Analyzed Umi Network docs: A MoveVM-based Layer 2 focused on AI agent payments.
- ✅ Configured Rabby Wallet for Umi Devnet (Chain ID: 42069).
- ✅ Exploring the "Umi Stack" for future node operator opportunities.
- Status: Participating in Devnet phase; monitoring for public node/testnet announcement.
- ✅ Followed navalabs-dev organization and starred active repositories (SDK & Take-home tests).
- ✅ Analyzed Nava's product stack: Understanding the Arbiter Verification layer and Execution Escrow SDK.
- ✅ Monitoring for the release of "Nava Chain" network layer and decentralized Arbiter node specs.
- Completed on-chain tasks: Swapping tokens and understanding the Locking & Voting mechanism.
- Obtained veIRS NFT via locking to participate in governance.
- Status: High-level user interaction completed; waiting for Node/Validator technical release.
- ✅ Applied for Founding Ascenders program.
- ✅ Executed on-chain interactions: Swaps and Liquidity Provision on Icarus Testnet.
- Monitoring for Node/Validator technical documentation
- ✅ Nava Labs: Successfully joined the waitlist for the Autonomous Agents infrastructure. Monitoring for "Agent Node" requirements. (Backers: Polychain, Polychain Capital, Hack VC).
- ✅ Icarus Finance: Application complete for early access. Linked wallet address and monitoring for the "Founding Ascenders" program.
- Decided to pivot from Nubit/Titan due to late-stage cycle.
- Researching Mina Protocol and Tempo Network as early-stage opportunities.
- Finalizing payment gateway troubleshooting (Bank Jago/PayPal).
Bagian ini berisi proyek yang dipantau namun tidak menjadi prioritas utama saat ini.
- Nubit (Light Node): Late-stage incentivized testnet. Resource observed.
- Titan Network: DePIN sharing node. Monitoring for future seasons.
sudo apt update: Memperbarui daftar paket.screen -S node: Membuat sesi terminal baru agar node tetap jalan.df -h: Mengecek sisa penyimpanan disk.
