Dogecoin

Network Basics

• Dogecoin is Bitcoin fork — similar UTXO model and transaction structure
• Proof of Work with Scrypt — merged mining with Litecoin
• 1 minute block time — faster than Bitcoin's 10 minutes
• No supply cap — inflationary by design, ~5 billion new DOGE per year
• Low transaction fees — typically less than 1 DOGE

Address Format

• Addresses start with "D" — legacy format, always verify first character
• 34 characters total — standard length like Bitcoin
• Case-sensitive — typos cause lost funds
• No SegWit or Taproot — simpler than modern Bitcoin

Transaction Characteristics

• Transactions confirm in ~1 minute — one block for basic confirmation
• 6 confirmations for high-value — ~6 minutes, same security practice as Bitcoin
• Fees are minimal — 1 DOGE per KB is standard, most transactions under 1 DOGE
• No RBF (Replace-By-Fee) — stuck transactions harder to fix than Bitcoin
• UTXO model — balance is sum of unspent outputs

Wallet Options

• Dogecoin Core full node — downloads entire blockchain, most secure
• MultiDoge light wallet — faster sync, SPV verification
• Ledger and Trezor support — hardware wallet integration
• Trust Wallet, Exodus — multi-coin wallets with DOGE support
• Avoid web wallets — custody risk, prefer local wallets

Common Issues

• Transaction unconfirmed — wait, DOGE doesn't have RBF to speed up
• "Dust" outputs — very small UTXOs may cost more in fees than value
• Wallet sync slow — Dogecoin Core needs full blockchain download
• Balance not showing — wallet not fully synced, wait for sync completion
• Sent to wrong address — transactions irreversible, triple-check addresses

Exchange Considerations

• Most major exchanges support DOGE — high liquidity pairs
• Withdrawals may have minimums — check exchange requirements
• Network confirmations required — usually 6-20 depending on exchange
• No memo/tag required — unlike XRP, simple address only
• Some exchanges don't support all address types — verify compatibility

Fee Management

• Fees based on transaction size in bytes — not DOGE amount
• Consolidating many small UTXOs costs more — larger transaction
• Most wallets calculate fees automatically — rarely need manual adjustment
• Minimum relay fee exists — transactions below threshold rejected by nodes
• During low activity, minimum fees always work — no fee market pressure

Security

• Standard cryptocurrency security — seed phrase is everything
• 12 or 24 word seed phrases — depends on wallet
• Never share private keys — no legitimate service asks for them
• Verify wallet downloads — get from official sources only
• Cold storage for large amounts — hardware wallet or paper wallet

Merged Mining

• Dogecoin merge-mined with Litecoin — shares Scrypt PoW
• Increases security — benefits from Litecoin's hashrate
• No action required from users — happens at mining level
• Makes 51% attacks more expensive — combined hashrate protection

Use Cases

• Tipping and microtransactions — low fees make small payments viable
• Community currency — strong meme culture and community
• Learning cryptocurrency — simpler than Bitcoin, lower stakes
• Payments where accepted — some merchants accept DOGE
• Speculation — high volatility, meme-driven price movements

Scam Recognition

• "Double your DOGE" always scam — no exceptions
• Fake Elon Musk giveaways — extremely common, all fake
• Phishing wallet sites — verify URLs carefully
• Mining apps that require deposit — legitimate mining doesn't work this way
• "Support" asking for keys — no real support needs private keys

Network Limitations

• No smart contracts — simple transaction-only blockchain
• No DeFi natively — wrapped DOGE exists on other chains
• No staking — Proof of Work only
• Limited development activity — slower updates than other chains
• Scalability similar to Bitcoin — throughput limitations
