Introduced on 28th August 2013 and released as open-source software, Incakoin (Symbol: NKA) is a digital currency and a payment system established by a group of programmers. The system is peer-to-peer, and transactions occur between participants directly without an intermediary. The network nodes verify these transactions which are recorded in a public decentralized ledger called the blockchain, which utilizes Incakoin as its unit of account. Because the system works with no intervention of any central repository or single administrator, Incakoins are designed as a reward in a competition in which members offer their computing power to verify and record Incakoin transactions into the blockchain. This activity is referred to as mining and successful miners are rewarded with transaction fees and newly created Incakoins. In addition to being obtained by mining, Incakoins holders can receive an extra 9% of there balance every 35 days. When sending Incakoins, users can pay an optional transaction fee to the miners, which may expedite the transaction being confirmed.
