LAX

Project Background

Parallax is an EVM-compatible Layer 1 blockchain built around Bitcoin-style monetary discipline and Ethereum-style programmability. The protocol supports smart contracts, decentralized applications, and Ethereum development tooling while using Proof of Work as its consensus mechanism.

The network uses XHash, a modified Ethash-derived Proof of Work algorithm designed to remain memory-hard and support commodity GPU mining. The project also provides Hashwarp, an open-source miner with OpenCL and CUDA support for participating in network security.

Parallax targets a ten-minute block interval and uses cumulative Proof of Work to determine the canonical chain. The protocol initially used a Bitcoin-style difficulty adjustment window before transitioning to ASERT difficulty adjustment at block 17,560 to provide more continuous adjustment toward the network's target block interval.

The EVM execution environment allows developers to deploy Solidity-based smart contracts and use established Ethereum development tools including Hardhat and Foundry. Parallax uses Chain ID 2110 and provides JSON-RPC infrastructure for applications, wallets, and other EVM-compatible services.

The reference client independently validates blocks and transactions according to the Parallax protocol rules. The project is open source and supports full nodes, mining, desktop software, command-line tools, and developer infrastructure.

History

Parallax launched its mainnet on October 28, 2025, as a Proof of Work blockchain combining Bitcoin-inspired monetary policy with an EVM execution environment. The genesis block was created with zero coin supply and no premine or privileged allocation.

The network's initial protocol used XHash, a modified Ethash variant designed to support GPU mining while changing the algorithm sufficiently to prevent existing Ethash ASIC hardware from being directly used for mining Parallax.

The initial monetary and consensus design established a 21 million LAX supply cap, 50 LAX initial block reward, ten-minute target blocks, and 210,000-block halving intervals. Transaction fees use a first-price auction model, with fees paid to miners rather than burned.

In December 2025, Parallax activated ASERT difficulty adjustment through PIP-0002. The upgrade replaced the previous difficulty adjustment mechanism with a continuous adjustment system designed to respond more smoothly to changes in network hashrate.

Development continued through 2026 with improvements to peer discovery, fee estimation, NAT traversal, desktop node software, synchronization, testing, and network security. The v2.0.0 release introduced a redesigned networking stack and expanded testing and hardening, while v2.1.0 added native Tor support and further networking improvements.

Tokenomics and Emissions

LAX has a fixed maximum supply of 21,000,000 coins. The supply at block zero was zero, and the network launched without a premine, foundation allocation, venture capital allocation, or developer fund.

The initial block subsidy is 50 LAX. The mining reward halves every 210,000 blocks, approximately every four years based on the ten-minute target block interval. New LAX is issued through Proof of Work mining according to the protocol's predetermined emission schedule.

Parallax does not use transaction fee burning. Its fee model is based on a first-price auction, with transaction fees paid in full to miners. This preserves the protocol's fixed monetary policy rather than introducing a fee-based supply reduction mechanism.

The network uses a 100-block coinbase maturity period. Miners must therefore wait for the required number of confirmations before newly mined block rewards can be spent.

The combination of a 21 million supply cap, scheduled halvings, Proof of Work issuance, and the absence of privileged allocations gives LAX a deterministic emission structure modeled around Bitcoin's monetary framework.

Roadmap

Parallax's development roadmap focuses on maintaining the Proof of Work settlement layer while expanding its EVM infrastructure, node software, mining ecosystem, developer tooling, and network accessibility.

Recent development has focused heavily on the reference client and peer-to-peer network. Improvements include redesigned discovery and handshake systems, DNS-based peer discovery, peer management, network diversity, synchronization, RPC functionality, and expanded testing and fuzzing.

The project is also developing desktop and command-line software for running Parallax nodes, along with mining infrastructure through Hashwarp. The desktop client is designed to make operating a full node more accessible without requiring users to manage the network exclusively from a terminal.

Future development includes continued work on EVM infrastructure, developer documentation, wallet and application compatibility, public RPC services, network infrastructure, mining tools, and additional privacy and networking capabilities such as Tor support.

Parallax development is conducted openly through its GitHub repositories and Parallax Improvement Proposal process, with protocol software, documentation, and supporting infrastructure maintained as open-source projects.
