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 build included)

🧪 How to Get Started

1. Download the binaries from this release or build from source.
2. Run a node (it will run the testnet by default since mainnet is not live yet):

   prlx

3. Start mining (optional):

   prlx --mine --miner.threads=2 --miner.coinbase <YOUR_WALLET_ADDRESS>

4. 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.
