Overview
Dogecoin Core Is The Official Full-node Wallet Of The Dogecoin Foundation, Designed For Dogecoin (DOGE). It Was Created In 2013 By Software Engineers Billy Markus And Jackson Palmer. It Is Based On Bitcoin Core And Uses The Scrypt Algorithm To Support A Wider Range Of Mining Devices. Dogecoin Core Is An Open-source, Non-custodial Wallet That Allows Users To Store, Send, Receive DOGE, Run Full Nodes To Support The Dogecoin Network, And Verify Blockchain Transactions. It Offers Dogecoin QT (Graphical Interface) And Dogecoind (Command Line Interface) With Support For Windows, MacOS And Linux Operating Systems For Users Who Want To Be Deeply Involved In The Dogecoin Network, Such As Node Operators, Miners And Service Providers. With An Emphasis On Security (local Storage Of Private Keys), Decentralization (no Need For Third-party Verification) And Community-driven, Dogecoin Core's Signature Shiba Inu Doghead (Doge Meme) Embodies Its "fun And Friendly Internet Currency" Philosophy. Despite Long Synchronization Times And High Resource Requirements, Dogecoin Core Is Considered One Of The Most Reliable DOGE Storage Methods Due To Its High Security And Network Support Features.
Services Provided
Dogecoin Core Provides The Following Core Services, Focusing On DOGE Asset Management, Network Support, And Decentralized Operations:
1. Digital Asset Management
- Supported Assets: Only Dogecoin (DOGE) Is Supported, Including On-chain Transactions. No Support For Other Cryptocurrencies (e.g. BTC, ETH) Or The Lightning Network.
- Asset View: Dogecoin QT Provides A Dashboard That Displays DOGE Balances, Unconfirmed Transactions, Transaction History, And Address Book. Support Multi-account Management (distinguished By Tags, Such As "main Account"). Users Can Choose DOGE Or Local Currency (such As RMB) To Display The Value (exchange Rate Needs To Be Obtained Online).
- Address Management: Support Legacy Address (starting With "D" Or "DE", 34 Characters), Generate A New Address Every Time You Receive To Enhance Privacy. Support Import/export Private Key And Address Book Management.
2. Transaction Service
- Instant Transfer: Support Sending And Receiving DOGE Via Address Or QR Code, Low Transaction Fee (0.01 DOGE/kB Recommended For 2024, About 0.0018 Dollars). Users Can Manually Adjust The Fee Or Select The Recommended Value (low, Standard, High). Transaction Confirmation Time Is About 1 Minute (block Time).
- Bulk Transaction: Support Sending DOGE To Multiple Addresses At Once, Suitable For Bulk Payment Or Distribution.
- Signed Message: Support Signing Message Via Private Key, Proving Address Ownership, Suitable For Verification Of Identity Or Social Media Authentication.

Support For Querying Historical Transactions And Balances After Synchronization.
3. Network Support And Mining
- Running A Full Node: Users Can Run Dogecoin Nodes, Supporting Network Decentralization And Preventing Censorship And DoS Attacks. Nodes Use Ports 22556 (mainnet) And 22555 (JSON-RPC, Closed By Default). In 2024, There Are About 5000 Active Nodes Worldwide (Blockchair Data).
- Mining Support: DOGE Mining With Scrypt Algorithm Is Supported, And Users Can Connect To The Mining Pool Through Nodes (such As ProHashing, ViaBTC). CPU Mining Is No Longer Efficient, And GPU Or ASIC Devices (such As Bitmain Antminer L3 +) Are Required.
- Backup Management: Backup Wallet.dat File (including Private Key) Is Supported, Which Can Be Stored On External Devices. Provide Dumpwallet And Backupwallet RPC Commands, And Only Write To The Specified Backup Directory (-backupdir).
4. Other Services
- JSON-RPC API: Provides A Self-documenting API (browse Through Dogecoin-cli Help), Supports Querying Balances, Transactions, Node Status, And Signing Messages, Suitable For Developer Integration (github.com/dogecoin/dogecoin).
- Libdogecoin: Launches C Language Library In 2022, Simplifies Developers To Build Dogecoin-compliant Applications (such As Payment Systems), Supports Python, Node.js, And Ruby, Without Having To Delve Into Encryption Details.
- Community Support: Helps Through X, Reddit, Telegram, And GitHub Discussions. Documentation Covers Installation, Backup, And Node Setup Guides.
- Tip Function: Support Sending DOGE Tips Directly Through Reddit (Dogetipbot, Active 2014-2017) And X, Manually Entering The Address Or Through A Third-party Tool.
Features
Dogecoin Core Combines Full Node Functionality And High Security, Suitable For Long-term Storage And Network Support. The Following Are Its Main Features:
