BlackCoin started of as a Proof of Work coin but has evolved to a unique version of Proof of Stake. Wallet users can unlock wallet for staking only. BlackCoin features the following specifications: - Extremely secure: Among first with fix on SSL heartbeat, Transaction malleability, BIP66 - The probability to sign a block and the block reward does not depend on coinage (anymore). - Recommended confirmations: 10, maturity: 500 - Minimum transaction fee: 0.0001 BLK - Defined block time target: 64 seconds - Max reorganization depth: 500 blocks - Inflation: about 0.95%. - PoS block reward: 1.5 BLK + fees - The accumulated reward is proportional to the total balance and the time of staking. 24/7 staking at current network weight leads to an expected reward ratio (interest rate) of about 5%. - BlackCoin rewards users who supports the blockchain through continuous staking.
The 2016 economic report “On the Value of Virtual Currencies” commissioned by the Bank of Canada, found three contributing components dictating a cryptocurrency’s exchange rate: The actual use of virtual currency to execute real payments. The decision of forward-looking investors to buy virtual currency (thereby effectively regulating its supply). The elements that jointly drive future consumer adoption and merchant acceptance of virtual currency. XAC Attention Addresses Attention Addresses are linked to AMARK consumer data and have specific rules enforced by the XAC protocol. There are two key functions of attention addresses: XAC-LOCK XAC-Lock is a feature that encourages continued consumer engagement with AMARK. The XAC sent to Attention Addresses is initially locked and becomes available after a maturation period. The XAC attention awards paid to consumers continually matures into availability as new XAC is earned from ongoing attention marketing. This process encourages engagement with AMARK as attention wallets will rarely have a zero XAC balance, giving consumers a consistent flow of value to spend within the ecosystem. XAC-BURN XAC-Burn is enforced at the protocol level. All transfers to Attention Addresses require 5% of the XAC transferred to be burned. The XAC -Burn feature is designed to align interests between merchants and consumers in the AMARK ecosystem. Anytime merchants use the AMARK platform for marketing, they are supporting the value of the XAC currency as protocol rules enforces a 5% burn. As such, merchants are effectively scaling the supply of XAC to match the demand from the ecosystem. This supply-side scaling mechanism will offset new coins introduced through block rewards and pressure the price of XAC to an equilibrium reflective of demand from the ecosystem.
