Release of ParkingChain is still a month or two away, best I can do at the moment is what I posted above, no big changes to that.
so, this is SWAP from PKB to PKC..??
No, It is not a swap from PKB to PKC.
It will likely be a PKB(Current Chain) to PKB(Smart Contract Chain). PKB holders will given some free PKC once the tokens have been released.
Heres a brief breakdown of what each part will do..
PKB tokens - Digital Currency for parking ticket purchases (Currently on own chain, may move to smart contract blockchain with PKC tokens)
PKC tokens - Digital tokens distributed by crowdsale on a smart contract blockchain used to operate the autonomous parking database (The ParkingChain)
The ParkingChain - Decentralized Database managed by Smart Contract - PKC is paid into SC to get read/write access, to register a node etc. and PKC is paid out of the SC to incentivise the nodes.
ParkingZones - Smart Contract which allocates unique parking zones; renewal fees & deposit required
ParkingAdmin - Opensource SDK Including Enforcement APPs, Admin/Financial/Management Dashboards
ParkingMeter - Opensource SDK which brings both PKB and PKC together by creating development kits with PKB as their default payment method. PKM will allow all methods of payments to switch over to using PKC to store ticket data and calculate tariffs by providing unrestricted opensource iOS/Android/WIndows/Linux/MAC application examples. We will also develop a modular main board to replace the main board in physical ticket machines which will run on the PKM module so an entire car park could be switched to digital ticketing without huge expense while keeping traditional cash methods. There is also the possibility of turning them into Digital Currency ATM's - They have printers, internet, coin validators and we'll be replacing the mainboards so why not?
So...
PKC is trying to get all data together in a single place so one car park could offer Ringgo, Parkmoble, ParkByte and Cash - It doesn't matter to them, their enforcement stays on the one platform - Customers could choose which provider they wish to use rather than installing multiple APPs because different car parks only use one provider.
PKB is trying to replace all Cash and Credit Card payments because they just cost too much and are not secure.
and what future of PKB..??you create PKB and then you create new chain with PKC..??
PKB will benefit hugely from the new chain PKC it is a necessary step for adoption of PKB, and as goldmaxx has said PKB holders will be rewarded with some PKC.
There are many reasons why we will use two chains;
Funding - PKB didn't raise any funds - PKC requires alot of development, it's an entire platform to change the way data is stored throughout a whole industry. When PKB was created the platform planned for it to operate would have been a private database on a much smaller scale, ran by a single entity; ParkByte Ltd. The ParkingChain will be autonomous, decentralized and not owned/controlled by a single entity.
Ecosystem - PKB will have 3.7million in supply (if I burned the premine) - PKC around 25million - Use of the ParkingChain will require alot of deposits in PKC, I would estimate 50% will be in deposits and in some cases will never move, they will pretty much be locked in an address for eternity. For instance, the ParkingChain Caretaker nodes will require 50,000PKC/$25k and will be locked in for 365days after giving 7days notice to terminate, leaving without notice will incur a penalty taken from the deposit before it is returned. I would say 100 Caretaker nodes @ 50k 5m PKC locked. ParkingChain Shards will also have similar, less harsh contracts which require less deposit but there will be more of these ... 10,000 * 500PKC/$250 = 5m PKC. That is 10m PKC taken out of the supply securing the database nodes. It costs alot to become either node, they need to be stable and secure which is why there will be hefty financial penalties - The higher the risk the more they will earn though. Remember The ParkingChain is autonomous - profits are used to pay for the services provided to the contract.
Scaling - This is the difficult one and is one of my concerns about moving PKB over to a chain like ETH. The ParkingChain is operated off a smart contract and most of the work will be done offchain - This is a micro transaction industry, 11million spaces in UK, lets say each get 2 tickets purchased a day (real world is some have 0 some have 20 a day) thats 22m tickets a day from UK alone - say 10 other countries like that joined 220m a day ... that is a huge amount of data ~2.5k txs/sec, could lets say ETH manage even 10% of that, atleast with PKB's current chain we have control over that scaling. Like I said its a concern putting me off moving PKB.
Fair Distribution - PKB was mined 100% (if premine burned), that is just a great feature in itself. Crowdsales/ICO/IPO or whatever you want to call it, PKC will be one of those and those do not have the same appeal.
Two separate Projects - They are two entirely separate projects - and should be seen as such. I'm not really talking about from a crypto speculator's view but from the view of the parking industry. Digital Currency is unregulated and different and people do not like unregulated and different. Blockchain Technology is revolutionary and can make industries efficient - PKB is Digital Currency - PKC is Blockchain Tech - In their eyes they want Blockchain Technology, they don't need to understand at such an early stage that with PKC (Blockchain Technology) naturally also comes with a built in ability to use PKB (Digital Currency).
I could go on but I feel I have probably given away more details than I wanted so I should stop
