📣🥳 We’re thrilled to launch the b18a Weekly Bounty Hunting challenge! Every week, we’ll focus on a specific category of entity, with boosted bounty rewards ranging from 20% to 70% extra b18a Ecosystem Points(👉About BEP).

🙌 This week, the theme is coin mixers, and the rewards are even bigger — each verified bounty data submission will earn an additional 50% points, totaling 3000 points per submission!

⏰ May 13 10:00 UTC — May 19 10:00 UTC

Ⅰ. What Are Coin Mixers?

Coin mixers, also known as “tumblers,” are services that mix specified amounts of cryptocurrencies in private pools before sending them to designated recipients. This process ensures anonymity in transactions, obscuring the connection between senders and receiver, while also making it difficult to trace who sent what to whom.

🔗 Coin Mixers List

Typically, the process looks like this:

  • A (Sender) ➡️ Coin Mixer (Mixer’s Address Unknown) ➡️ B (Receiver)
  • To find the coin mixer’s address, you can:
  1. Check transactions where A sends to a known coin mixer address.
  2. Track transactions where B receives from a coin mixer to infer the mixer’s address.

Ⅱ. How to Participate:

  1. Collect Information:

Use Google to search for mixing services, like “blender.io,” and identify known coin mixer addresses.

2. Submit Data

Record the addresses of mixing services and submit them to b18a protocol — Bounty Hunting - Submit Address.

3. Transaction History Check

If the coin mixer address isn’t directly provided, you can track the transaction history on a blockchain explorer to find outbound addresses from the coin mixer, leading you to the correct address.

Remember, coin mixers usually charge a small fee, around 1–3% of the total amount.

Ⅲ. How to Earn Points:

  • Bonus Rewards: This week, every validated coin mixer data submission earns 3000 points (2000 base points + 50% extra).
  • Invite Friends: Share your referral link, and when others join and submit bounty data, you both earn extra points.

Ⅳ. End

While b18a’s mission is to improve the transparency and traceability of blockchain transactions, we remain neutral regarding the use of coin mixers. Our focus is on understanding the flow of funds, not on dictating how users should manage their assets.

However, we want to remind everyone that using coin mixers can carry risks, especially when it comes to compliance with centralized exchanges (CEX) and regulatory institutions. Always consider the implications and potential legal risks before using such services. Ultimately, the choice is yours, but staying informed is crucial!

Now, get ready to take on the coin mixer challenge! Let’s make the most of this week’s bounty hunting with boosted rewards! 🚀
