Can you shine a little more details? Does that mean ICOs in China are illegal to operate and participate in by the Chinese?

This afternoon, China's official qualitative ICO is illegal open-ended financing behavior, as if only the heat price is not affected

That was a very welcome update on things. Looking forward to everything ramping up in the near future. Pieces are falling to places. Balance leasing is a very welcome feature. Waiting for the micro services like a mad man.

Hi all,

Hope you are all doing well.
Please allow me a moment to give a short update about where we stand with HEAT technical development.

Lets start with one thing that's clear, but perhaps underapreciated, which are the big improvements to the HEAT network stability since the last major release. HEAT network has operated smoothly and uninterupted ever since, thankfully!

Also the extensive client/wallet/exchange visual makeover and overall upgrade seems to work well, no major bugs have surfaced or any emergency fixes have been needed since that was released. This ofcourse being possible because of our very special, very custom heat-ui crypto-client framework. Which in turn allows our client developer to perform his magic efficiently.

During the holiday season work was started on the software backend for our licensed EUR wallet operator. Through this new company with which Heat Ledger Ltd has a partnership we will be bringing EUR to the blockchain. Users can deposit and withdrawal EUR to and from their account and send EUR from one account to any other account in the system.

To realize this we decided a private blockchain system together with an indexed database and an API was the way to go.

In order for HEAT to benefit most it became clear that instead of forking HEAT and building a private chain from that code, a better way was to upgrade HEAT itself by adding private chain functionality to its core. This way the system would benefit from later upgrades to HEAT and HEAT itself would benefit.

We went a little further than that by making HEAT core into an embeddable software component, this means that now other applications can add the HEAT library and use it.

By embedding the HEAT library in your application;

- you get your own private blockchain and p2p network
- you can extend and use the HEAT database
- you can expose your own custom API by extending the (OpenAPI compatible) HEAT API

All this came very close to what we needed to built our backend system, the only part that was missing was a database solution.

The database had to;

- be protected against data loss, this means we needed realtime backups to multiple servers
- record all changes to its data
- be impossible to change data without it being detected

Of course solutions for such exist, but most are costly to implement and maintain. What we found was a way to achieve the same by using the blockchain and a simple sql database.

For this we first created our basic database models, in software developement a database model is a piece of code that wraps all your database queries and inserts and updates into a unit. From there we identified all inserts and updates and created what we call 'messages' to pass data into those models. The messages are basically data structures but with the ability to turn them into binary data and vice versa create them from binary data.

To be able to pass a message to one of the model's insert or update routines we created what we call 'handlers', each handler having its unique id. The handlers in turn are invoked by observing the embedded private blockchain transactions, if we see a transaction with a message we look up its handler and the handler will pass the message to the database model.

So there you have it. We now have all our data backed up on the private chain p2p network and no one can change any part without rewriting the blockchain. Pretty cool!

The messages + handler logic will be ported to HEAT core at a later stage, we plan to wrap the logic in such a way that with a few lines of code you could built your blockchain powered database driven app.

We also created the web/mobile client for the EUR wallet operator. For this we took heat-ui framework as a starting point, we dressed it down, took the best parts and upgraded it which gives us a nice mobile friendly client framework. This code is expected to find its way back to HEAT as our upgraded mobile friendly wallet base. The wallet is mostly functional and will be passed down to our visual/ui specialist to complete its looks.

Also our java developer recently completed work adding MYSQL support to HEAT. HEAT replicators have always been designed to work with multiple database engines but up to now we only supported H2 database. MySQL is better suited for heavy loads which is why we will soon be using that to power the public wallet at https://heatwallet.com.

Heat-ui (the HEAT wallet) has a number of upgrades pending release, among which is better mobile support and the addition of mouseover/popover details to things like accounts, orders and trades.

Preparations have also been going on to better formalize microservices and to enable balance leasing which can be expected in the coming release.

Also preparations for the remake of the p2p/networking layer are on going and will be implemented next.

Hasn't been listed instead of wasn't. Reasons being multiple, the time hasn't been ripe yet:

- closed source for now
- features not ready at the desired level for optimal visitor conversion and stickiness
- ambitious project with development plan spanning 2+ years
- unique, POS based tech possibly hindering willingness to list by some exchanges (although we do provide NXT compatible api module)

HEAT is currently listed on 3 external exchanges and there should soon be more. We however don't consider listing on 3rd parties to be the single major critical factor for user adoption.

Let's not exaggerate. HEAT's mission is to contribute to the migration from centralized exchanges to decentralized ones with its own technology, creating value to shareholders, token holders and the whole token exchange ecosystem through that process.

This token wants to replace centralised exchanges? So why wasn't it listed on these centralised exchanges to introduce the token directly to the users we are hoping to attract to heats exchange?

Heat Ledger Ltd is integrating infrastructure in co-operation with the current HEAT AE XEL gateway operator, to make XEL a company certified asset and improve its exposure. Completion of this process will make adding of further company backed cryptocurrency gateways on the HEAT AE more straightforward.

You can try to reinstall your JAVA, here is a link, download the 64-bit Windows version. http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

How do I tell if Blockchain is DL?

Can anyone confirm it is working on a certain version of Java? Ill check mine.
Using windows. could be a permissions prob. would submitting my full error log help you guys troubleshoot?

HEAT's technical roots are in the NXT codebase and we've co-operated extensively with NXT previously (FIMK wallet used to support NXT, and HEAT lead dev has contributed to NXT core team). Based on this we're following the IGNIS ICO and ARDOR launch, which we prefer to succeed as Heat Ledger Ltd received a significant stake of NXT and ARDOR in the HEAT ICO in August 2016. Thus contributing for NXT, IGNIS and ARDOR success will be making Heat Ledger Ltd company holdings and consequently the HEAT token (with delayed effect, though) more valuable.

The IGNIS sold on heat AE is IOU's and backed up by company NXT holdings. They will be getting IGNIS at a 1:2 ratio IGNIS:NXT after the official ICO. The price could be lower, I agree fully. It is close to last ICO round price. Though you have to take into consideration that you might not be lucky in the official one. I've participated in every round and have come out empty handed.

is this IGNIS related to Heat or completely different? are you doing something co-operative beside IGNIS being traded on HEAT wallet? i bought some, but heat/ignis ratio is pretty overvalued compared to ignis ico price... why is it that IGNIS ico price in NXT is 3x cheaper than minimun price in HEAT? hmm.

What OS?

Permissions problem?  Not an expert here.  Maybe file creation is being blocked by some kind of antimalware/antivirus program you're running?

I'm not familiar with that error but yes, after starting the server you should wait for the blockchain to download. Are you sure you have got the right java installed?

Dudes,

I'm clicking "Start Server" and I see the toggle move over, then it says "IOException cannot construct blocks file or related maps" and "HEAT server 1.1.0 stopped." Do I need to wait for blockchain to DL or something? Not very clear..

Thanks! All new BTC depositors are receiving complimentary 0.05 HEAT at their first deposit. Sending HEAT to all fresh, empty accounts isn't feasible.

ABN AMRO? We delivered the demo project, after which that particular department at ABN fell under extensive restructuring causing further slowdown of the already slow bank decision making processes. It was agreed we'll return to the project later this year. Time will tell. We don't mind, as it leaves us more resources to concentrate on the areas closer to our core competence: cryptocurrency and asset exchange.

I'm not quite sure but I think the faucet requires a depositing new account... I might be wrong.

congrats devs for succesfull project so far. maybe you could do something about the persisting problem that new accounts cant buy Heat because of first transaction requires Heat. Dunno if it's on top of your priority list or no, well, the older members on community are now sending some Heat to new accounts when they request it on trollbox, but yeah.

how's the bank deal going?

Nice to see the new thread :-)

Sit still and enjoy the ride!
