Axfund Coin (AXF), based on open-source Bitcoin technology, uses an improved cryptographic algorithm. It launched in December 2014, and for the first 30 months, it adopted a Proof of Work (POW) mechanism. In May 2017, it transitioned to a Proof of Stake (POS) mechanism by updating the wallet. The codes security and stability are maintained by professional technicians, and Axfund itself is also open-source.
