First launched in 2017 to provide an energy-efficient alternative to Bitcoin and proof of work consensus, BitGreen utilizes its proprietary protocol and behavioral science to catalyze everyday impactful actions at scale. Funded by the blockchain’s governance protocol, users are able to discover and act on impact opportunities, such as using bikeshare programs or volunteering, and are rewarded with BITG, all through the BitGReen light wallet app. Users can also explore a growing global ecosystem of sustainable vendors, vetted charities, and carbon offset programs all accepting or distributing BITG. All BITG holders are members of the BitGreen community and can nominate new impact actions and causes to be adopted. Incorporated in Wyoming, with an office in New York City and a global community, the BitGreen community is executing on the potential that blockchain has for shaping a healthy, resilient and just world.

SpectreCoin (XSPEC) is an innovative privacy-focused cryptocurrency, featuring an energy-efficient proof-of-stake algorithm that provides rapid transaction confirmations, ring signatures for privacy and anonymity, and a fully integrated Tor+OBFS4 layer for IP obfuscation within the wallet. Spectrecoin is actively developed, with an ambitious roadmap that prioritises privacy, security, and true decentralisation with features such as default stealth addresses and stealth staking, and low-power mobile wallet staking in our upcoming Android wallet. Spectrecoin can be exchanged on several exchanges. The goal of Spectrecoin is to combine a blockchain with a tokenized ring-signature scheme to build a system of anonymous digital cash. The ring-signature scheme used here was first introduced by Shadowcat, and is now being improved on by the Spectrecoin developers. For network-level privacy, all nodes communicate exclusively within the Tor network via hidden services. The priorities of the Spectrecoin project are on privacy, technical soundness and simplicity. The Proof-of-Stake consensus method is used to provide environmental friendliness, decentralization and transaction speed. The project is built by a professional team and around the open participation of its community members, development is funded through an innovative staking-reward donation system and voluntary direct funding.
