The difference between Bitcoin and PKT is its proof of work. PKT is a fork of the Bitcoin code base (btcd), but replaces Bitcoin’s SHA-256 with PacketCrypt, the world’s first and only bandwidth-based proof of work. Bitcoin has a 10 minute block time and PacketCrypt uses 1 minute blocktime. Bitcoin has a 21 million coin cap and PKT has 6 billion coin cap. Bitcoin mining rewards halve every 4 years. PKT has what is called a decimation every 100 days, during which mining yields decrease by 10%. With PKT, 20% of each mined block goes to the Network Steward wallet, which funds R&D of the PKT ecosystem.
