The ArcBlock Token is entirely implemented with Blocklet and its distributed ledger in ArcBlock. ABT is 1:1 ERC-20 tokens which means it tie its development to Ethereum community that allows developer to take advantage of an existing ecosystem. ABT is a utility token that use to pay for the cost of ArcBlock service in the same way as Cloud computing service.
Unlike transaction fees in Ethereum or Bitcoin, the Application provider need to pay transaction fees for their end users. The Developers would get requested to lock in some ABT as a stake when they need to provide a critical service. But in the other hand, the developer can create their own token that inherit all the features from ABT to start their own new tokenized economy too. ArcBlock also have its own decentralized blockchain Marketplace for their reusable components such as Chain Adapters, Blocklets and applications.
