The wallet.dat file is the only source of truth for your TALER Coin wallet. This Berkeley DB database file contains everything needed to access and spend your coins: Critical Data Stored: Private Keys: Cryptographic keys that control your TALER Coin HD Wallet Seed: Master seed for hierarchical deterministic key derivation Transaction History: Complete record of all wallet transactions Address Book: Saved addresses with labels Key Metadata: Creation times, derivation paths, key associations Master Encryption Key: Encrypted key material (when wallet is encrypted) File Location:

Mining & Staking

Mon, 01 Jan 0001 00:00:00 +0000

This guide covers how to earn TALER Coin rewards through Proof-of-Stake (PoS) staking using the GUI wallet. Understanding TALER Blockchain’s Consensus TALER Blockchain uses a hybrid Proof-of-Work (PoW) and Proof-of-Stake (PoS) consensus mechanism: Proof-of-Work (PoW): Miners generate blocks using computational power Proof-of-Stake (PoS): Coin holders stake their coins to generate blocks This guide focuses on PoS staking, which is the recommended method for most users as it: Requires no specialized hardware Consumes minimal electricity Allows you to earn passive rewards on your existing TALER holdings Helps secure the network What is PoS Staking?

Architecture

Mon, 01 Jan 0001 00:00:00 +0000

This document describes the technical architecture of the TALER Blockchain, covering consensus mechanics, economic model, network protocol, and storage internals. All details are derived from the TALER Blockchain source code. Overview TALER Blockchain is a Bitcoin Core-based blockchain that implements a hybrid Proof-of-Work / Proof-of-Stake consensus model. Both PoW and PoS blocks coexist on the same chain, each governed by independent difficulty targets and block spacing rules. Genesis date: September 13, 2017 Codebase lineage: Bitcoin Core (UTXO model, script system, peer protocol) Block types: PoW blocks and PoS blocks interleaved on one chain Consensus Mechanism The chain accepts both PoW-mined and PoS-minted blocks.

Running a Node

Mon, 01 Jan 0001 00:00:00 +0000

This guide covers how to set up and run a full TALER Blockchain node. What is a TALER Blockchain Node? A TALER Blockchain node is a full participant in the blockchain network that: Validates Transactions: Verifies all transactions according to consensus rules Maintains Blockchain: Stores the complete transaction history Relays Data: Forwards valid transactions and blocks to other nodes Supports Network: Contributes to network decentralization and security Enables Mining/Staking: Allows you to participate in block generation Running a node helps secure the TALER Blockchain network and gives you full control over your blockchain interactions.

Command Line (talerd)

Mon, 01 Jan 0001 00:00:00 +0000

This guide provides comprehensive documentation for talerd (the TALER Blockchain daemon) and taler-cli (command-line interface) tools. Overview TALER Blockchain provides two primary command-line tools: talerd: The blockchain daemon that runs the full node taler-cli: Command-line tool to interact with the running daemon talerd - TALER Blockchain Daemon The talerd daemon is the core TALER Blockchain node software.

Community Seed Servers

Mon, 01 Jan 0001 00:00:00 +0000

Seed servers help TALER Blockchain nodes discover peers when joining the network. TALER Blockchain uses a combination of hardcoded seeds and a community-maintained seed list to ensure reliable connectivity and decentralization. How Peer Discovery Works When a TALER Blockchain node starts, it needs to find other nodes to connect to. This happens in several stages: Hardcoded DNS Seeds - Built into the node binary, these are DNS names that resolve to known TALER Blockchain nodes Hardcoded Fixed IP Seeds - A fallback list of IP addresses compiled into the binary Community Seed List - A remote bootstrap.

History

A community account of how TALER came to be - written from the perspective of early enthusiasts who lived through the project’s first months. This is not an official press release. It is a candid retelling of how things actually happened in 2017 and early 2018. 2017: Two Founders and a Constructor In the beginning there were two: Lavnikevich (henceforth “the Creator”) and Lavrinenko. In 2017 they spawned TALER on walletbuilders.
