Haven Protocol
untraceable payments x stable value storage


Haven has successfully hardforked to V2!

V2 Features:
  • Increased minimum ring size from 5 to 10 for increased privacy and anonymity
  • PoW algorithim changed from Cryptonight to Cryptonight Heavy which is ASIC resistant and not currently listed on nicehash
  • Updated to latest LWMA difficulty algorithim implementation to stop timewarp attacks and improve reliability of block timings
  • Support for subaddresses in GUI wallet
  • Various small performance improvements

Use https://github.com/IndeedMiners/xmr-aeon-stak/releases/tag/2.4.3 to mine for the new algorithm.


Introduction

Haven is an untraceable cryptocurrency that proposes a mix of standard market pricing and stable fiat value storage without an unsustainable peg or asset backing. It will achieve this by using a built in on-chain smart contract that controls the minting and burning of coins to facilitate value for users that choose to send their coins to offshore storage contracts while allowing everyone else to be exposed to the natural price movements of the currency.

Haven is a fork of Monero so inherits the stealth and anonymity that it’s famous for. Haven also has the benefit of starting the blockchain from scratch with RingCT for extra privacy. Further, Haven’s offshore storage smart contract allows privacy conscious individuals that want to keep their money in an untraceable currency without being subject to market fluctuations, a means to do so.


Offshore Storage

Haven doesn’t rely on a peg to maintain a relationship with fiat currency and can be traded at any value without affecting those who want to maintain the relationship. It does this via a built in smart contract called offshore storage. Sending Haven to offshore storage (burning) records a reference on the blockchain to the current fiat value which can be restored later back into Haven by minting new coins to the tune of the current fiat value.

The key use cases for offshore contracts are:

Point of sales systems where goods can be bought with Haven and shop keepers can immediately lock the fiat value in to protect from price fluctuations. This has the added benefit of keeping the shopkeepers business and income completely hidden on the blockchain as his wallet address nor amounts are revealed.

Storing large amount of money outside of the traditional banking system. Privacy focused cryptos are perfect for this but without a reliable way to maintain value through fluctuations the process of holding could be costly. Sending Haven offshore quite literally, makes money disappear until you want it back at which point the value remains intact.


In order for cryptocurrencies to be accepted into the mainstream, there must be a way to abstract the exchange risk associated with holding the currency relative to fiat. Once Haven is supported in point of sales systems and this process becomes automated, adoption will increase rapidly.

Offshore Storage contracts will be implemented once the network reaches a mature stage with enough exchange support to allow redundancy and accuracy of prices. The current focus is on growth, stability, privacy and usability for everyday transactions with an easy to use mobile wallet app that anyone can use without prior knowledge of crypto.


Supply & Emission

Total supply: 18,400,000 coins before tail emission and coins minted and burned via offshore storage.
Coin symbol: XHV
Coin Units:
1 picohaven/havtoshi = 0.000000000001 XHV (10^-12 -smallest unit)
1 nanohaven = 0.000000001 XHV (10^-9)
1 microhaven = 0.000001 XHV (10^-6)
1 millihaven = 0.001 XHV (10^-3)
Hash algorithm: CryptoNight CryptoNight Heavy (Proof-Of-Work)
Block time: 120 seconds


Donation/Bounty Wallets

The first 95,000 Haven were mined prior to this bitcointalk announcement to the address shown below.
This will be used further in the future to fund development and large scale projects

Roadmap

Haven aims to be a cryptocurrency you can use in everyday life from buying coffee to buying houses. Our focuses this year are on:

  • Developing mobile wallets for IOS and Android with a focus on users with no previous knowledge of crypto payments.
  • Building a network of businesses that will integrate Haven into their point of sales systems and accept as a form of payment.
  • Once the network reaches maturity, release the offshore storage smart contract allowing stability of value in terms of fiat currency.

Every time a block is mined, a certain amount of BTC (called the subsidy) is created out of thin air and given to the miner. The subsidy halves every four years and will reach 0 in about 130 years.

Are those solo pools? Pending balance is staying at zero, although shares are accepted and blocks are found...?

Edit:My bad.. already found the answer from luckypool discord...:

XHV block mature after 60 blocks so it will take time to have pending balance

Mining some.

FYI: Pool needs something like 2h to show coins under "pending". 60 confirmations needed.

Just read the thread, and I think it's a good project, but it still lack of information here in the thread.
Could you please add more information, such as website or a white paper for this project.
