Parallax v1.0.3 - Mainnet Launch
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
- 🧱 Docs: https://docs.parallaxchain.org
- 💡 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)
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
Parallax v0.1.3 (Testnet)
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.
Full Changelog: v0.1.2...v0.1.3
Parallax v0.1.2 (Testnet)
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
Parallax v0.1.1 (Testnet)
This release includes:
- Fix crash when synchronizing the testnet chain from scratch
- Additional testnet bootnode
Full Changelog: v0.1.0...v0.1.1
Parallax v0.1.0 (Testnet)
We are excited to announce the first public release of Parallax, a new blockchain client built as a fork of go-ethereum with key modifications inspired by Bitcoin’s neutrality and ossified rules.
This release marks the launch of the Parallax Testnet. Developers, miners, and community members are invited to join, test, and help us refine the network before mainnet launch.
✨ Highlights
- Consensus: Proof-of-Work via Ethash, secured with Bitcoin-style rules for timestamp handling, difficulty adjustment, and block validity.
- Block Timing: Configured for ~10 minute blocks, aligning with Bitcoin’s cadence.
- Community Mining: Includes a built-in CPU miner for accessibility. GPU mining is feasible and expected to be community-driven.
- Neutral Design: No pre-mine, no insiders, no privileged accounts. Parallax aims to be a permissionless, decentralized, and neutral timechain.
- Genesis Block: Contains unique extra data to timestamp the network’s creation, ensuring verifiable neutrality.
🔧 What’s Included
- Full client implementation (
prlx) - Integrated CPU miner for testnet participation
- RPC endpoints compatible with existing Ethereum tooling
- Docker support for easier deployment (
docker buildincluded)
🧪 How to Get Started
- Download the binaries from this release or build from source.
- Run a node (it will run the testnet by default since mainnet is not live yet):
prlx
- Start mining (optional):
prlx --mine --miner.threads=2 --miner.coinbase <YOUR_WALLET_ADDRESS>
- Join the community: Share feedback, issues, and suggestions to help shape Parallax.
🔮 What’s Next
- Community testing and feedback on consensus rules.
- Explorer, faucets, and developer tooling.
- Preparing for the mainnet genesis with finalized parameters.
Parallax exists to see what happens when neutrality meets programmability.
