Parallax v1.0.5

Andre Patta
Changelog v1.0.5
- Fix an issue where miners could continue hashing on outdated block templates for extended periods, resulting in blocks being found with stale timestamps.
- The miner now always refreshes the block header timestamp and rebuilds the sealing template on a regular timer.
- The default recommit interval is now 20 seconds, with bounds set to a minimum of 5 seconds and a maximum of 2 minutes.
- These changes prevent difficulty overshooting and timestamp drift observed in previous builds.
Pools and node operators are strongly advised to update as soon as possible to help restore proper block cadence and difficulty stability across the network in the next DAA window.

Changelog v1.0.4
- Fix node synchronization in
snapmode. - Change default sync mode back to
parallax-snapto speed up sync.
Changelog v1.0.3
- Change default sync mode from
parallax-snaptofull.
Changelog v1.0.2
- Rename the
snapsync protocol toparallax-snap. This make sure other non-Parallax compliant nodes stop finding Parallax nodes via the discovery protocol.
Changelog v1.0.1
- Fix warning messages about dropping peers in main chain.
🌌 Overview
After months of development, testing, and refinement, Parallax Mainnet is now live.
This marks the beginning of a new decentralized era — a Bitcoin-inspired, EVM-compatible blockchain that fuses deterministic monetary policy with full smart-contract capabilities.
Parallax is a clean-room fork of go-ethereum, meticulously re-engineered to follow Bitcoin’s ossified economic model while introducing an entirely new Proof-of-Work algorithm, XHash, purpose-built for fairness, verifiability, and long-term sustainability.
⚙️ Core Highlights
🔐 Immutable Monetary Policy
- Hard-capped at 21 million coins
- Block reward of 50 coins, halving every 210 000 blocks
- No premine, no dev-fund, no pre-allocation — 100% fair launch
- Follows a deterministic emission curve identical to Bitcoin’s
⚡ Consensus Algorithm: XHash
- Custom GPU/CPU PoW algorithm derived from Ethash
- Epoch length: 720 blocks
- Modified FNV-1 round function with Parallax-specific constants
- Optimized for verifiability and ASIC resistance
- Fully open-source miner: Hashwarp
🧠 Full EVM Compatibility
- Complete support for Ethereum smart contracts, tooling, and RPCs
- Metamask / Chainlist-ready endpoints
- Compatible with major development frameworks (Hardhat, Foundry, Thirdweb, etc.)
🕸️ Network Rules & Timings
- 10-minute target block time
- Difficulty retargeting via Nakamoto-style median-time-past adjustment
- Genesis timestamp: 2025-10-28 19:00 GMT
- Chain ID: 2110
🧩 Mining Tools
Hashwarp Miner
Minimal GPU/CPU miner for XHash.
- OpenCL 1.2 + compatible
- CUDA 12.x compatible
- Easy CLI interface:
hashwarp -P http://127.0.0.1:8545
Latest release: v1.2.0
🔭 Developer Ecosystem

- 💡 Beginner Guides https://docs.parallaxchain.org/guides/client/introduction
🪙 Fair Launch Policy
Parallax launched with zero premine and open GPU mining from block 0.
All coins in circulation are verifiably mined on-chain.
The Genesis block contains no privileged allocations — only the protocol definition and a genesis message:

Parallax v0.1.4 (Testnet)

Andre Patta
This release fixes two vulnerabilities originated from go-ethereum v1.10.0+ clients.
- PRLX-2025-01 (High): GHSA-7ww4-x27h-p6hf
- PRLX-2025-02 (High): GHSA-xc79-566c-j4qx

What's Changed
- XHash implementaiton for Parallax by @andrepatta in #1
This release introduces the XHash algorithm as discussed here: https://bitcointalk.org/index.php?topic=5560698.msg65873804#msg65873804
In accordance with testnet node operators and miners, the testnet was reset from genesis block with the XHash proof-of-work algorithm. Please make sure you clean the block chain data directory before starting your node!
This release allow users, miners and node operators to test the XHash algorithm ahead of the mainnet launch.

Parallax v0.1.2 (Testnet)
c5a4054
andrepatta
Andre Patta
This is minor release with no additional functionalities or bug fixes and it's meant to test the stability of the Parallax client ahead of the Parallax mainnet launch on October 28th.
This release includes clean ups of code - or inactive features - inherited from Geth, such as:
- Removal of all references to Ethereum's DAO fork
- Removal of all references to Ethereum's Glacier (difficulty bomb) forks
- Removal of all references to Ethereum's PoS Beacon system
In addition, we've upgraded the project linter to go-lint 2.5.0. This release also include several lint fixes throughout the entire code base.
Node operators are advised to upgrade to help test client stability in preparation for the mainnet release.
If you are running the Parallax testnet, starting with this release, you are required to pass the --testnet flag to prlx to properly sync to the testnet chain. The absence of this flag makes the Parallax client sync with mainnet chain which is not live yet.
Full Changelog: v0.1.1...v0.1.2
