General HEAT Discussion / HEAT WALLET 2.7.0 | HEAT SERVER 2.5.2
« Last post by verymuchso on September 14, 2018, 03:52:58 PM »
  New Releases:
HEAT Server 2.5.2 | HEAT Wallet 2.7.0

These are optional but recommended updates.

Online wallet is here:


Wallet updates:

After introducing native Ethereum support to HEAT wallet allowing you to use your HEAT master key as a parent key for your Ethereum addresses, we now present native Bitcoin support to HEAT wallet. Supported are Bitcoin private keys as well as BIP44 compatible seeds.

To assist users downloading and setting up your own copy of HEAT wallet in order to store and handle your HEAT, Bitcoin or Ethereum we introduce this first part of Getting Started With HEAT Wallet, please check it out.

In addition to Bitcoin support, the following updates were made to the wallet:

  • Improved installer and settings handling. (Un)installing HEAT wallet will no longer delete your blockchain.
  • Improved mouseover features for charting in the Asset Exchange.
  • Improvements to the build system giving us much smaller compiled javascripts which helps render the pages faster when you visit the wallet online at
  • Improvements to block explorer search when searching for Accounts, Blocks, Transactions
  • QR codes are now used to display Bitcoin deposit addresses in the Asset Exchange
  • API failover. User interface automatically switches API servers in case one is performing badly
  • External dependencies and Chrome app renderer upgraded to latest versions
  • Legacy NXT API protocol support disabled for default desktop, see heat.legacy.enableAPIServer in the config files to enable this if you rely on that behavior

Server updates:

The HEAT 2.5.2 Server is an optional update, it mostly aggregates completed improvements and a number of bug fixes.

An improvement deserving special mention - we’ve added a new dialect to the peer 2 peer communication protocol (how servers talk amongst each other). Only new servers using the 2.5.2 version are capable of using this more advanced protocol. When your server talks to older servers the old dialect will be used.

The new communication protocol is based on instead of HEAT has added full fledged AVRO encoding and decoding support to both the core HEAT server as well as the SDK (sdk = native browser + nodejs libs).

With AVRO enabled you can expect a ~3-5 times network traffic reduction.

The biggest boost however is its CPU usage. Especially on high loads the amount of memory used and CPU power needed drops from significant to almost non existent. Both encoding and decoding happens up to 100s of times faster than before.

Other notable updates to the server code:

  • Fixed a bug in reporting of the total coin supply. While not important in any way from a p2p or technical aspect, with this fix there now are 25,776 more HEAT than was thought before, an increase of 0,07%! Thanks to the sharp community members for pointing this out! You know who you are.
  • Support for WebRTC decentralized signaling server was added which plays a role in our future decentralized messaging network plans
  • All external dependencies have been upgraded to their latest versions
  • Support for use of OS environment variables in config files (, use this syntax[NAME_OF_ENV_VAR_GOES_HERE]
  • Some new API methods and improvements
  • New p2p/network health/node monitoring system with build in email reporter

Other notable updates:

HEAT-SDK (software development kit - browser+server) was promoted to version 1.0.1 recently and is becoming an ever more important part of our arsenal and a vital building block of our own and third party projects.

We implemented a mini Paper Wallet utility which assists you to store and administer your private keys. It is functional as is with one drawback: the generated keys are old style HEAT keys which means you can’t derive Bitcoin or Ethereum addresses from them. You CAN however create paper wallets with your BIP44 compatible keys you created in the main HEAT wallet.

Hey everyone,

Is there a youtube video for doing the set-up of a wallets and online staking? Barrier to extry/ adoption will be pretty slow if we can't explain in basic terms.

HEAT goes Multi-Currency starting with Ethereum and ERC20 token support.


This is a HEAT server included release which gives you the new HEAT multi-currency wallet manager.

Gradually we'll be adding more cryptocurrencies starting with this release for Ethereum
and the Ethereum ERC20 tokens.

An update to the HEAT twelve-word secret phrase generator was applied making HEAT seeds
compatible with BIP39 [].

Your HEAT seed now also becomes the basis for your Ethereum and Bitcoin HD wallets.

So thats one 12-word phrase giving you access to all your crypto holdings.

The Ethereum part of the wallet manager is implemented on top of
which implements a HD wallet and gives you an endless list of addresses all derived
from a single seed.

ERC20 tokens sending feature is under development still and will follow soon.

What is supported is the display of your token balances (HEAT Assets & ERC20 tokens), the
display of your transaction history (ABI aware transaction details which means transaction
details are parsed from the raw transaction.input - supported ABI's are expected to increase).

Most of the development work has been for behind the scenes stuff like remaking the client
structure to support multiple different currencies and updates to the wallet structure,
however experienced HEAT users will notice still quite a lot changed. The new
wallet manager screen is no doubt the largest visual update.

We hope you'll enjoy this release.

Updating/preserving your blockchain:

In order to preserve your blockchain from your previous installation so you dont have to download it, follow these steps.

Step 1. Backup your blockchain folder (video

Step 2. Install HEAT WALLET 2.6.3

Step 3. Restore your blockchain folder (video

The steps are the same on Macs and Linux desktops.



This is a light weight version of HEAT Wallet which does not include the HEAT server.

General HEAT Discussion / HEAT WALLET 2.5.0 (FULL CLIENT DESKTOP WIndows/Linux)
« Last post by verymuchso on April 03, 2018, 09:53:30 PM »

Hard fork set for block 1,245,000 which is somewhere around next Friday (April 6th).

Download available:


This desktop wallet release embeds the 2.5.0 server version which is a mandatory update. If your wallet does not use the built in server (default behavior of the wallet is to connect to a remote API node) you could still use that but you'll lack the client side (UI) improvements.


Windows and Linux versions.
Mac OS version will follow.


Apart from the all important embedded server update this release contains dozens of fixes and improvements among some of the more notable are:

  • Visual warning when sending to non existing accounts
  • Visual warning when sending to accounts without public key
  • Correct display of virtual balance in account explorer (virtual balance includes trades based on unconfirmed transactions)
  • Asset Exchange websocket order books updates got fixed, updates as well when no new order is added but just on trades
  • You can switch to beta network from the about dialog now (beta net toolbar color is red) (for developers and beta net testers)
  • Recipient auto complete includes all numeric account ids now

Heatledger 2.5.0

This is a mandatory update, all nodes on the network need to run this version or higher.

Nodes below 2.4.0 will automatically be blacklisted by this version.

Nodes on 2.4.0 will remain working untill we reach block 1,245,000 as of when
a hardfork will take place.

This version will perform a one time scan of the blockchain on startup.

## Installation

To install and run heatledger you need Java JDK 1.8 or higher installed, note that
JDK is different from standard java distributions.

On ubuntu we use sudo apt-get install default-jdk package. For other platforms
please look here

For configuration settings see the conf/ files in the installation folder.

## Whats in this release

### No more forks

First and foremost this release fixes the occasional forks that occurred and which
required node operators to do the regular rescans of the blockchain. Those rescans
are not needed anymore as HEAT is now considered stable.

### Stable Storage Engine

HEAT is different from other crypto currencies because of its special custom
build storage engine. Our unique storage engine is what allows us to scale in
size and speed. Building this engine however proved more difficult than
using a one size fits all - off-the shelf - storage engine like every other
crypto out there.

Our hard work however paid off which leads us to this stable and mature 2.5.0

### Benchmark

This version supports benchmark mode which allows you to participate in the
upcoming HEAT Benchmark Competition. Instructions for this will follow but
participating requires at the very least that you run a HEAT server. Once you
run a HEAT server on main net it will be easy to run a second HEAT server
on the same machine but on benchmark net.

### High Speed Binary API

We are moving away from JSON as a transport mechanism and are instead adopting
the binary AVRO encoding from HADOOP. One of the parts that makes it possible
to run a benchmark server which does many thousands of transactions a second
over the internet is the use of binary data over websockets.  
This version has that new RPC mechanism to which you can talk from your browser,
mobile or NodeJS app. Interfacing with HEAT is made possible through our
officially supported HEAT-SDK

### Adjustable Fees (spam protection)

Transaction fees can be remotely raised or lowered by the developers without the
need to update the software. An incubation period of 24 hours is observed before
the new fees take affect. This allows us to already lower the fees and raise
them again in case of misuse.

This is a temporary measure. Once block file splitting is enabled we dont care
about this anymore since the chain can grow indefinitely from then on.

We will start lowering the fees after the hard fork.  

### Mem Pool Fixes

While technically a part of the storage engine, it is worth mentioning that the
unconfirmed transaction pool had a bug fixed which caused unconfirmed transactions
to be improperly rolled back. Leading to forks due to balance differences between

### Adjust heat.maxApiRecords

Use this setting to raise the number of rows returned from the various API's.

### Virtual Order Matcher

This is enabled again by default, the virtual matcher matches orders and generates
trades in real-time based on unconfirmed transactions.

### Numeric Account Ids

Numeric account ids are included in account search and in every autocomplete
now when sending transactions.
