The post Bitcoin Additional Launches BTCa v2 appeared on BitcoinEthereumNews.com. Bitcoin Additional (BTCa), a blockchain fork of Bitcoin built on Proof-of-Stake (PoS) and Islamic ethical principles, announces the launch of BTCa v2, a major network upgrade designed to strengthen scalability, reliability, and accessibility for the global Muslim community and ethical investors. Key Upgrade Highlights Masternode Collateral – Running a masternode now requires 1 BTCa collateral only, opening access to a wider pool of investors. Block Rewards – Each masternode validating transactions will earn 0.001 BTCa per block, distributed automatically. Total Supply – Capped at 210,000 BTCa, with minting set at one coin per 1,000 minutes (0.001 BTCa/min). Pre-mine Allocation – Approximately 2,200 BTCa pre-mined and fully distributed to active masternodes. New Features in BTCa v2 Improved Ecomining – Lower entry thresholds and optimized staking-like yield generation. Multi-node Capability – Increased efficiency for masternode operations. Lightweight Wallets – New wallets consume fewer server resources. Reliability Boost – Enhanced stability and security for node operators and users. All tokens minted previously on Bitcoin Additional v.1 will be swapped  1:1 – all BTCa holders will receive a new BTCa v2. Why BTCa Matters BTCa was launched in 2022 to enable fair, low-cost, and transparent microtransactions, particularly for charitable giving (zakat, sadaqah, personal aid). Unlike Bitcoin, where high fees and slow transaction speed hinder small transfers, BTCa provides: Low fees suitable for distributing small donations. Fast transaction finality for community use cases. A system aligned with Shariah principles by avoiding interest, excessive speculation, and unjust enrichment. For over three years, BTCa has powered blockchain-based charity and integrated with the Quan2um ecosystem, with adoption across Central Asia, the Caucasus, Middle East, Turkey, and Africa. Open-Source & Transparency BTCa remains fully open-source and verifiable: Code Repository: github.com/bitcoinadditional/BTCA Blockchain Explorer: cryptoscope.io/btca Source: https://beincrypto.com/bitcoin-additional-launches-btca-v2-upgraded-blockchain-with-ethical-pos-consensus/
