After successful testing of the new code, we are pleased to announce Haven’s mainnet will upgrade to Monero v0.16 by conducting a hard fork at block height 741,957 or approximately 14:30 GMT on December 8, 2020.

This date has been selected to give pool operators and exchanges two weeks to prepare for a smooth transition. This release will be known as Haven ‘Artemis’ v1.2.0. You can find the source code on GitHub here.

This exciting step for the Haven team and community moves the protocol forward on multiple fronts:

Artemis enables the new Haven Web Vault

An updated version of the Haven Web Vault will go live with the fork, giving easy access and control to a far broader range of Haven users. It will also enable xUSD functionality, so users can convert and transfer from any device, including mobile and tablet, from anywhere in the world. …

Haven Protocol will be conducting a hard fork on December 8, 2020 to implement a number of major upgrades.

The hard fork will upgrade Haven’s codebase to Monero v0.16, allowing for faster daemon performance and improved transaction verification.

These upgrades will also allow for the re-launch of the Haven Web Vault with complete functionality for xUSD conversions and transactions. An updated Haven Desktop Vault will also be released shortly after the fork is complete.

Regarding Haven’s fees: after extensive testing and community feedback, we’ve identified opportunities to further improve the Haven 2.0 fee structure announced in September. The hard fork will proceed without a change in fees. The existing fee structure has proven effective in preventing attacks and is essential to ensure Haven’s promise that “1 xUSD will always be redeemable for $1 worth of XHV.” …

As always it’s been another busy month building Haven’s ecosystem of private assets. Here’s a brief overview of what’s been going on:

v0.16 Codebase Testnet

As part of the preparations to upgrade the Haven codebase to Monero v0.16 we have conducted multiple testnets. These have provided valuable data and feedback to the devs to ensure a smooth fork and subsequent running of the network.

Among other items we have tested the following:

  • Load testing for bottleneck analysis
  • Band Protocol price feed testing and failover integration/testing
  • Implementing improved error messaging from test feedback
  • Testing new fee structure (not included in v0.16)
  • Other minor UX/UI bugs and…

We’re pleased to announce that Haven has partnered with Band Protocol to integrate an additional decentralized oracle price feed into the Haven network.

Band Protocol will initially provide a USD price feed for XHV to allow for in-Vault conversions to xUSD. We are already working closely with Band Protocol to integrate and test additional price feeds for our upcoming xAssets (xGOLD, xSILV, xEUR, and xCNY) in phase two.

The Band Protocol oracle is currently being utilized in testnet, and will go live on Haven’s mainnet after the hard fork implementing the v0.16 upgrade. …

Today the Haven team would like to share a few updates regarding the numerous projects we have underway.

v0.16 Codebase Upgrade

Development work on the v0.16 codebase is almost complete, and testing is ongoing. This upgrade includes several protocol improvements including:

  • New xAsset conversion and transfer fee structure (more details here)
  • Improvements to the daemon performance
  • Integration of new oracle provider

As this is a significant and important protocol upgrade, there will be several stages to the testing to ensure a smooth fork and subsequent running of the network:

Stage 1: Closed testnet using CLI

Stage 2: Integration of new fees/v0.16 into web vault backend and internal…

We are very excited to announce that Haven Protocol has been listed on BKEX!

Trading goes live today at 20:30 (UTC+8).

This is a critical step to expanding access to financial privacy for our users throughout Asia, and will allow access for the first time to the wider Chinese community that has shown a lot of interest in Haven. BKEX is the 4th largest exchange in China. We hope this will assist some of the Chinese investors who have shown long term interest in the project and struggled to find a suitable exchange to use.

As the first listing of an XHV/USDT pair, this listing with BKEX marks another important step for the project, and we also hope that the USDT pairing will allow a new angle for traders by spreading our pricing across more platforms and pairs. …

Over the last month, a number of third-parties have asked us to create a resilient, long-term fee structure for xUSD transactions on the Haven network.

We’ve agreed to do so and the reason is clear: in order for xUSD to be used regularly by millions of people, on the largest platforms in the world, we must implement a solution that ensures fees paid by users are flexible and transparent.

So, the first announcement we’re making today during Haven’s multi-week “Announcement Season” is the Haven 2.0 Fee Structure. These fees are designed to thwart economic attacks and manipulation attempts, while maintaining Haven’s stable storage use case and long-standing promise that “1 xUSD will always be redeemable for $1 worth of XHV”. …

The Haven team is thrilled with the successful launch of xUSD. For the first time, a USD stablecoin with Monero-grade privacy protections is now available to anyone in the world.

In just two weeks we have seen the use of xUSD skyrocket. This demonstrates that users are demanding a private stablecoin option in the market, and that Haven’s unique mint and burn protocol for xUSD exchanges is working flawlessly.

Unfortunately, the successful launch of xUSD also brought with it significant attempts to gain control of XHV supply by large holders focused on manipulation. …

We’re excited to share additional details about the hard fork process that will be used to launch the world’s first private stablecoin, xUSD, on July 20th. Today we published the mainnet release code to enable xUSD functionality on Haven’s network.

Haven’s Apollo v1.0.0 is set to fork on July 20th at block height 640640, or roughly 15:00 GMT+1. Functionality for xUSD transactions will be enabled automatically 10 blocks later during a second fork at block height 640650.

This mechanism is being used to ensure that pricing records are already recorded in previous blocks for use when xUSD transactions go live. …
