OChristmas: Make Private Transactions Rewarding

Welcome to OChristmas

OChristmas is live on Ocash Mainnet AlphašŸŽ„

This OChristmas, every Ocash transaction comes with rewards.

Send, withdraw, and move value privately on-chain — and earn as you do.

Private by default. Simple to use. Built for real on-chain value movement.

What Is OChristmas?

OChristmas is a limited‑time rewards campaign running on Ocash Mainnet Alpha.

During the campaign:

  • Transfers and withdrawals with submitted UTXO Certificates generate points
  • Points determine how rewards are shared
  • A total of 1,000,000 ZKJ is distributed to participants

If you transact on Ocash during the campaign period, you’re already participating.

How Participation Works

Getting started takes just a few steps:

  1. Register on Ocash and receive your internal Ocash address
  2. Deposit supported tokens from Ethereum or BNB Chain
  3. Complete an internal transfer or an on‑chain withdrawal
  4. Submit your transaction proof (UTXO Certificate)

Once your proof is submitted, the transaction is counted toward points.

How Points Are Calculated

Points are calculated based on UTXO usage.

Ocash uses a UTXO‑based model, similar to Bitcoin. Each transfer or withdrawal may use 1 or more UTXO inputs. The number of UTXO used depends on your account’s UTXO distribution and the transaction amount.

For OChristmas:

  • 1 UTXO spent = 1 point

After completing a transfer, you must submit the UTXO Certificates to prove the transaction. Transfers without submitted certificates remain private and cannot be recorded for points.

Rewards and Distribution

OChristmas features a total prize pool of 1,000,000 ZKJ.

Monthly Points Distribution

  • 800,000 ZKJ is distributed proportionally based on points earned during the campaign period

Top 20 Bonuses

An additional 200,000 ZKJ is reserved for the top 20 participants:

  • 1st place: 50,000 ZKJ
  • 2nd–3rd place: 30,000 ZKJ each
  • 4th–10th place: 10,000 ZKJ each
  • 11th–20th place: 2,000 ZKJ each

Reward Distribution

Rewards will be distributed within 14 days after the event ends.

Ocash reserves the right to adjust distribution rules if needed to maintain fairness.
