TOS coin was developed in the form of an Alternative coin, using scrypt algorithm. A block is created every 1 minute and each block is able to
process 420 transactions. Figure 1 shows the specification of TOS coin, compared to Bitcoin and Ethereum. Those 3 coins all take POW as a mining type. The amount of minable TOS coin is limited at 6 billion, larger than that of Bitcoin which is 21 million. The limit of the minable amount of TOS coin is higher because it needs to be spent for developing and operating essential elements of the coin as a means of payment, for business purposes such as customer
promotion and for reserve in case of risk compensation.
