AMEX proposes a system that utilizes a multi-signature topology as well as account permissioning and whitelisting in three separate hardware enclaves of internet connected devices. This will be done in such a way that the user retains custody of their private keys, while also having a high degree of security, with minimal interaction or forethought by the user. The proposed system will consist of a smartphone app, a smart agent (internet connected appliance). It will be possible with our coming project DEFRAG. While many see the benefits of a price-stable cryptocurrency that combines the best of both fiat and Bitcoin, not many have a clear plan for the adoption of such a currency. Since the value of a currency as a medium of exchange is mainly driven by its network effects, a successful new digital currency needs to maximize adoption in order to become useful. We propose a cryptocurrency, AMEX which is both price-stable and growth-driven. It achieves price-stability via an elastic money supply, enabled by stable mining incentives. It also uses seigniorage created by its minting operations as transaction stimulus, thereby facilitating adoption. There is demand for a decentralized, price-stable money protocol in both fiat and blockchain economies. If such a protocol succeeds, then it will have a significant impact as the best use case for cryptocurrencies. We will give to all our holders AntiWhale, NoBot Tech Frontrun and Cross-Chain Bridge System.
