Generation 3.0 Crypto

H.E.A.T. Ledger stands for Heuristically Enhanced Asynchronous Transactions Ledger, embodying a completely new way of structuring cryptocurrency and peer-to-peer decentralized asset ledger. Optimized for speed and architected with custom private chains in mind, HEAT readily provides excellent solution for crowdfunding and IPO arrangements of any size.

Unlimited scalability

HEAT's unbounded vertical scalability is only limited by the performance of the hardware used. Utilizing not a single blockchain but a chain of them, and removing embedded databases through the use of off-heap memory mapped binary files, the HEAT blockchain is able to sustain transaction throughput of at least 1000 tps 24/7.

Multisig Currencies

The unique HEAT crypto client provides access to major cryptocurrencies including BTC, ETH, FIMK and NXT. Distributed Apps, Instant Messaging and Multi-Sig capabilities of the client ensure security and latest features for all: 3rd party cryptocurrencies and fiat tokens in the native HEAT custom Asset-2-Asset exchange.


You must have heard of the issue of "scalability" which most popular blockchains face. The issue of handling ever increasing number of transactions on the blockchain puts constantly increasing pressure on each node in the network. The HEAT technology removes this pitfall by intelligently combining the best features of the existing 2.0 cryptos with a completely remade, sliced binary blockchain mechanism. Using custom built storage and access solution, based on Memory Mapped Files, data stored on disk can be accessed in random sequence and at near RAM memory speeds - without the need to load this data in RAM. Splitting blockchain into separate files for homogenous data types such as unconfirmed and confirmed balances, unconfirmed and confirmed asset buy and sell orders etc. the HEAT Java server is capable of achieving an unbelievable 30 million updates per second on commonly available 16-core server.

Example use cases for HEAT Ledger's Distributed Services Acrhitecture

1. Oracle service
An oracle writes a (foreign) fact to the blockchain. Through the oracle it becomes possible to create a transaction on the HEAT blockchain that does not execute until an event outside the HEAT blockchain has happened. The best example of using an oracle is probably if Bob sends Alice HEAT tokens but the transaction will not execute before the oracle service writes the transaction details of Alice about her BTC payment to Bob.

2. Escrow service
Request a new escrow, both parties send money to the escrow. Escrow will not release before both parties agree. Could be combined with oracle service where escrow releases funds based on an oracle saying the requirements are met, as in previous example.

3. Time based secret reveal service
Based on certain date or time, transaction on the HEAT blockchain or some other real world event coming from an oracle this service releases some secret, or decrypts encrypted data you gave it in advance.

4. Co-signer service
For use with multi-sig transactions on BTC/ETH/HEAT/etc. The user of this service will use the service provider public key as a required co-signer of a multi signature transaction. When the requirement is met the service provider will add his signature to the multi-sig transaction which will then execute.

5. Gateway trade bot service
With a gateway bot service you can buy/sell cryptocurrency on an exchange. An example of such a service is where users can send ETH to the service ETH address. When received the service will immediately sell the ETH for BTC and transfer the real BTC to the seller.

6. Seller of Digital Goods
If you sell digital goods on the internet (music or video files for instance) you could create a service where upon payment you either return a link to download the digital product or you could return a cryptographic key for the buyer to unlock the digital product.
