In The 9th Raider story, wallets can be operated with thin mobile hand held devices that communicate with a low orbitital satellite network, bypassing phone networks and towers. And they run cryptocurrency. ARK cryptocurrency.

In reality, your imagination is the only limit to this. In the near future, inventory and supply chain control can be tied directly to the ARK blockchain and using ARK’s custom transaction creation, it would automatically adjust on chain, auto order new inventory when low, auto pay the company and only release the inventory when payment is complete. This is all possible now in fact. Even using HTLC we can lock payments until custom time frames or jobs are completed. This is also one way ARK is interoperable. It can auto convert old world money(fiat) or old coins into ARK coins. You can also send secret messages using ARK. Each transaction has a vendor field for text or code. You can send special code to do whatever you want, even encrypted code that only a certain user/person designated can unlock/access/read. You could even set it so the secret message or code action can only be unlocked with a large sum of money or a set device with it’s ID stored on chain, then once the device is close to the holder of the marked transaction it will unlock when NFC connected. A safezone as you say, could have it’s location be encrypted in a multisig account transaction, you could have the coordinates split into multiple accounts and the only way to decrypt is to have all accounts sign a decrypt transaction. Even large sums of money or access to an object/door/location/anything can be tied to multisig. This is all possible now, not just in the future.

But with Ark, you would have to attack the character and take their ARK, but they still need access to it, like a safe, they still need the mnemonic code to unlock it. This code/phrase is 12-24 words in real life, which is nearly impossible to hack even with Ark tokens.

The ARK network is run by 51 forging nodes. A node is a computer that runs a specific program that fully validates transactions and blocks. A node operator is called a delegate or validator. We would say if a character in the movie in the year 2020, held their ARK tokens and staked them for all those years until the year 2037, they would be “old money” and very wealthy and powerful. In order to become a delegate/node the ARK network requires you to be voted in. 1 ARK = 1 vote on the network. The most votes gets you into the top 51, here you can see a simple text based breakdown of the top delegates on the ARK network, at https://explorer.ark.io/VoteReport.txt. Every 8 seconds, one of the delegates validates/forges a block. This block is added to the blockchain and immutable. For validating that block, the network rewards the delegate with 2 ARK. This gives the network and users adopting the ARK token a steady deflationary supply. Voting on the network could also be used for many things even for leadership over a tribe in the story or for making decisions of critical supplies.
