What is Sapphire?

Brief Introduction

EtherGem’s Sapphire, an integrated subchain with DeX, is a PoW blockchain with a target 5 seconds block time that observes the EGEM chain while conducting independent business on its own structure. Miners "solo" or "dual” mine SFRX (with EGEM!). Our mining algorithm is Blake2s with custom modifications based on community support for things like ASIC resistance. Sapphire can be mined with both CPU and GPU, using our custom built miner. Sapphire uses the same EGEM account address users are accustomed to holds a multicurrency balance, with a rebuild of the Opal wallet to facilitate these enhancements. The decentralized exchange trades on chain from this wallet. Original coins can launch on the sapphire chain as a mineable ICO and transfer or trade out of the same address. Other chain currencies can be locked in “quantum swaps” in this same multicurrency wallet. We loosely call this our “5 second BTC” (link to proof on bitcointalk). Early EGEM adopters received 2 times their EGEM holdings as a Sapphire airdrop taken at EGEM block 1,530,000 with balances available at launch on Sapphire chain.
