Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

BVM-SDK

Modular Blockchain Framework in TypeScript

BVM-SDK adalah toolkit open-source untuk membangun blockchain modular dengan cepat.
Mirip konsep Cosmos SDK atau Substrate, tapi dibuat lebih mudah diakses menggunakan TypeScript — cocok untuk prototipe, simulasi ekonomi, wallet/explorer, dan pengembangan client-side.

Catatan penting (2026 update):
Semua modul core telah diperbaiki secara signifikan:

  • Async I/O penuh
  • Persistence pakai LevelDB (BVMStore)
  • Keamanan dasar ditingkatkan (canonical serialization, timeout, validation)
  • Konsistensi nama class & export
  • Cross-platform & lebih scalable untuk testnet kecil

SDK ini bukan untuk jalankan mainnet production (karena keterbatasan Node.js/TS di validator node).
Untuk mainnet real, migrasikan modul critical (Consensus, Staking, Validator, P2P) ke Cosmos SDK (Go) atau Substrate (Rust), sementara BVM-SDK tetap jadi client SDK & tooling layer.

Fitur Utama

  • Modular design — pakai hanya modul yang dibutuhkan (Bank, Staking, NFT, DEX, Bridge, VM, dll.)
  • Ekonomi configurable — halving, max supply, reward, fee via bvm-config.ts
  • Persistence LevelDB — state aman & cepat (bukan JSON file lagi)
  • Wallet generator + HTML viewer — tampilan balance & NFT sederhana
  • P2P discovery sederhana — bootstrap & gossip peer
  • Dashboard & API — monitoring node via Express
  • Bridge prototype — bridge out/in antar chain (proof placeholder)
  • Finality manager — simulasi L2 ke L1 checkpoint
  • Validator & Miner — validasi blok + PoW sederhana
  • TypeScript-first — type-safe, mudah di-extend

Instalasi

npm install bvm-sdk
# atau yarn add bvm-sdk




# Quick Start

# generate wallet

import { generateWalletWeb } from 'bvm-sdk';

await generateWalletWeb({
  outputDir: './my-wallet-backup',   // opsional
  // password: 'rahasia123'          // nanti untuk enkripsi (belum full)
});

# Membuat my-wallet.json dan wallet.html → buka di browser untuk lihat saldo & NFT.2. Jalankan Dashboard & P2Pts

import { BVMDashboard, BVMStore, P2PDiscovery } from 'bvm-sdk';

const store = new BVMStore();
const p2p = new P2PDiscovery(['your-bootstrap-ip:3000']);

const dashboard = new BVMDashboard(store, p2p, 3001);
dashboard.start(); // http://localhost:3001

Akses /health, /peers, atau POST ke /join untuk bootstrap.

# Contoh transfer sederhana

import { BankModule, BVMStore } from 'bvm-sdk';

const store = new BVMStore();
const bank = new BankModule(store);

await bank.credit('BVM1abc123...', 1000, 'REWARD');
const balance = await bank.getBalance('BVM1abc123...');
console.log(balance); // 1000
