🔥 EMBERCHAIN (EMBR) 🔥

Custom EVM Blockchain · Browser Mining · Privacy Pool

A new experimental Proof-of-Work EVM ecosystem

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

⚡ WHAT IS EMBERCHAIN? ⚡

Emberchain (EMBR) is a custom EVM-compatible blockchain built from the ground up.

Unlike traditional token deployments, Emberchain runs its own:

• Custom Proof-of-Work consensus
• EVM-compatible execution layer
• Native blockchain infrastructure
• Browser-based mining system
• Built-in privacy pool for shielded transactions

The goal of Emberchain is to combine the flexibility of smart contracts with optional privacy and an easy onboarding experience where anyone can participate directly from their browser.

The chain is live. Mining is open.

⛏ HOW TO MINE EMBERCHAIN ⛏

No GPU required. No miner software required. No pool setup required.

Anyone can participate:

• Visit:

https://emberchain.org

• Create or import an Emberchain wallet
• Open the mining dashboard
• Click "Start Mining"
  
  
• Your browser begins mining using a background WebWorker

The miner displays:

• Live hashrate
• Current mining status
• Best hash found
• Blocks discovered

Every browser can participate.

The more computing power contributed, the higher your chance of discovering blocks.

Current mining phase: SOLO MINING ONLY

Mining pool support will arrive as network participation grows.

━━━━━━━━ MINING ROADMAP ━━━━━━━━

🔥 PHASE 1 — BROWSER MINING (LIVE)

Emberchain begins with accessible browser-based mining.

No downloads.
No complicated configuration.
No specialized hardware.

The goal is a fair early distribution where anyone can participate.

As more miners join, difficulty automatically adjusts to maintain the target block time.


⚡ PHASE 2 — GPU MINING

As network difficulty increases, GPU miners will naturally enter.

Pool support will be introduced to allow miners to receive consistent payouts.

The Keccak256 algorithm is GPU compatible, allowing future mining expansion without changing the network.


🔒 PHASE 3 — PROOF OF STAKE (LONG TERM)

The long-term roadmap includes a transition toward Proof-of-Stake.

A future merge block may transition block production from miners to EMBR validators.

All mined EMBR remains valid and eligible for staking.

The goal:

• Fair initial distribution
• Community-driven growth
• Sustainable long-term security

🔐 PRIVACY POOL 🔐

Emberchain includes an optional shielded transaction layer.

Users can perform private exchanges where:

• Transaction amounts are hidden
• Counterparties are hidden
• Privacy proofs are verified at the protocol level
• Double-spend protection remains enforced on-chain

Privacy is optional — users can still use transparent EVM transactions for smart contracts and public applications.

Development Update | July 16, 2026

[ANN][EMBR] Emberchain Wallet — Progress Update #[X]

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Greetings Emberchain community,

We've been heads-down building and have a solid batch of improvements to share. Below is a full breakdown of everything shipped today, followed by what's on the immediate roadmap. As always, the chain is live, mining is open, and the exchange is running peer-to-peer.


✅ UPDATES SHIPPED TODAY

📒 Address Book — Save and label wallet addresses you send to regularly. Add contacts with a name, address, and optional notes. Access via the new "Address Book" page in the sidebar. Each contact has a one-click copy, direct send button, and full edit/delete support stored locally in your browser.

👥 Contact Picker on Transfer Page — When you have saved contacts, an "Address Book" button now appears on the Send page. Click it to pick a contact and auto-fill the recipient field — no more copy-pasting long hex addresses.

📱 QR Code / Receive Screen — A new QR icon sits next to your wallet address on the dashboard. Clicking it opens a modal with a scannable QR code of your address plus a copy button. Makes receiving EMBR on mobile or sharing your address much easier.

📈 EMBR/USD Price History Chart — New "Price Chart" tab on the Exchange page. Pulls every completed trade and uses CoinGecko's historical price API to calculate the implied EMBR/USD price at the time of each trade (ETH, SOL, BTC trades all normalized to USD; USDT trades use $1.00 directly). Displays as an interactive line chart with all-time high, all-time low, latest price, and total % change since first trade.

⛏️ Active Miners Counter — The dashboard now shows a live count of active miners. The server persists miner activity across restarts so the count is accurate even after a reboot.

🏆 Explorer Holder List — Cap Removed — The top holders list was previously limited to 20 addresses. That limit has been removed.

⚙️ Difficulty Display Fix — Block difficulty now displays in abbreviated human-readable format (e.g. 4.37B instead of an overflowing raw number) on both the dashboard and block explorer.

📜 Trade History Tab on Exchange — A dedicated "Trade History" tab on the Exchange page shows all fulfilled listings with per-currency average EMBR pricing.

🚪 Sidebar Eject — Proper Redirect On Mobile — Disconnecting your wallet from the sidebar now correctly redirects you back to the wallet setup screen.



🔜 COMING NEXT

💬 Telegram & Discord Group — Official community channels are being set up. Announcements, mining coordination, and exchange listings will all be accessible there. Links will be posted as soon as live.

🪙 ERC-20 Token Support — The chain's EVM layer is already running. Next step is full ERC-20 support so custom tokens can be deployed and tracked within the wallet — balances, transfers, and contract interaction.

🔐 Wallet Backup & Export Flow — A guided flow for exporting and backing up your private key and wallet credentials securely. Critical for anyone serious about long-term holdings.

🌐 Community App with EMBR Login (Partially On-Chain) — A Reddit/Discord-style community board where you log in with your EMBR wallet. Posts, reactions, and reputation are partially anchored on-chain. Think decentralized forum with social features — built for the Emberchain community first.

🔥 EMBERCHAIN — UPDATE
What's new since the last post

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

▌ PROPORTIONAL SHARE POOL — NOW LIVE

Block rewards are no longer winner-takes-all.
Traditional PoW gives 100% of the block reward to whoever finds the winning nonce. Emberchain now splits it proportionally across every miner who did work that round. Small miners earn steadily. Big miners earn exactly what their hash rate deserves. Nobody takes a cut.

How it works:

• The mining template now returns two targets — target (full block) and shareTarget (64× easier)
• Every valid share hash you submit during a round is recorded against your address
• When any miner finds the winning block, the 5 EMBR reward is split proportionally by share count
• If you submitted 30 out of 60 total shares that round, you receive 2.5 EMBR — regardless of who found the block
• Zero pool fee. Every wei of the block reward goes to miners
• Payout breakdown per miner is stored on each block and visible in the explorer

What changed for external miners:

• One new endpoint: POST /api/mining/share — call it whenever your hash meets shareTarget
• That's it. The submit endpoint for winning blocks is unchanged

The updated Python script in the OP handles share submission automatically.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

▌ SHARE POOL IS CHEAT-RESISTANT

A few things confirmed with automated tests before shipping:

• Wrong difficulty rejected — a share hash that only meets a lower difficulty than the current chain target is refused
• Stale work rejected — a header with the wrong parentHash or wrong block number is refused even if the hash is valid
• Duplicate nonces rejected — submitting the same nonce twice in a round earns exactly one share, not two
• Restarts don't reset the nonce set — the server persists submitted nonces to disk; you can't replay a nonce by timing a restart
• Shares survive restarts mid-round — if the server restarts before a block is found, your accumulated shares carry forward into the payout
• Dust is handled correctly — rounding remainder always goes to the last miner; total payouts always equal exactly 5 EMBR

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

▌ P2P ESCROW — EXPANDED USDT SUPPORT

USDT is now accepted across all four major networks:

• USDT ERC-20 — Ethereum mainnet (was already supported)
• USDT TRC-20 — Tron network ← NEW
• USDT BEP-20 — BNB Chain ← NEW
• USDT Polygon — Polygon mainnet ← NEW

Sellers can specify which networks they accept. Buyers pick whichever chain suits them. Payment verification is handled on-chain by the node — no manual confirmation step.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

▌ P2P ESCROW — RACE CONDITION PROTECTION

When a listing is live, multiple buyers can see it at the same time. Previously, two buyers could attempt to claim the same listing simultaneously and one would lose their payment window without warning.

This is now fixed:

• The moment a buyer clicks Reserve, the listing is locked exclusively to their address
• Other buyers see it as unavailable immediately — no race
• The reservation holds for 15 minutes, then expires and the listing reopens
• If the buyer doesn't pay in time, the seller's EMBR stays in escrow and the listing becomes available again
• Enforced at the chain level — the server cannot accidentally double-assign a reservation

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

▌ CRYPTO ON-RAMP — BUY AND TRADE IMMEDIATELY

New users no longer need to already hold crypto to participate in the escrow exchange.

• A built-in on-ramp lets you purchase ETH, BTC, SOL, or USDT (any supported network) directly from the wallet interface
• Funds land in your external wallet within minutes
• From there, reserve a listing and pay — the full flow from zero crypto to holding EMBR is now in one place

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

▌ WALLET BACKUP AND RESTORE

• Export your wallet as an encrypted keystore file (AES-256, password-protected)
• Re-import on any device — wrong password fails clearly, not silently
• Private key never leaves the browser unencrypted

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

▌ BROWSER MINING — UPDATED STATS

• Live share count shown while mining — how many shares you've banked this round
• Live estimated payout % — your current cut of the block reward based on shares submitted so far
• Both update in real time as shares land
