Add Parallax mainnet & testnet (PRLX)

[andrepatta]

This PR registers Parallax in ethereum-lists/chains.

The purpose of this submission is to lock in the chainId (2110) and networkId (2110) for Parallax. Public RPC endpoints and an explorer will be added in a future update once the mainnet is live in November.

Parallax is a new timechain protocol that merges Bitcoin’s monetary discipline with Ethereum’s programmability. It operates under Bitcoin’s fixed rules — Proof of Work, 10-minute blocks, halving cycles, and a capped 21M supply — while embedding the Ethereum Virtual Machine for smart contract execution.

Key properties:

• Consensus: Proof of Work (Ethash)
• Block Interval: 10 minutes (600s)
• Difficulty Adjustment: Every 2016 blocks (≈ 2 weeks), bounded by ×4/÷4 (Bitcoin-style)
• Block Reward: 50 coins, halving every 210,000 blocks (~4 years)
• Supply Cap: 21,000,000 PRLX
• Execution Environment: Ethereum Virtual Machine (EVM)
• Fee Model: First-price auction (no burning, no EIP-1559)

Ethos & Neutrality

• No premine, no foundation allocation, no privileged accounts.
• Genesis block will include the title of a reputable news article to prove it was not pre-mined.
• Monetary rules (21M cap, halving schedule, PoW consensus) are immutable and cannot be changed via governance.
• Accessible Ethash mining favors GPUs, promoting decentralization.

You successfully submitted a PR! Due to the amount of PRs coming in: we will only look at PRs that the CI is happy with. We can also not hold your hand getting the CI green - just look how others that where merged did it and RTFM. So as long as there is any CI check that reports an error - no human will look at this. You might be able to ask for some support after supporting the project - e.g. by sending funds to lists.eth. When you fixed things after a requested change - then you also need to (re-)request a review.
