Launched on Dec 18th last year, Mystica marks the first steps of B² Network. In the past 30+ days, Mystica has achieved the following:

🔸The basic technical structure of B² Rollup has been established;
🔸BlockHeadz NFTs have been minted, and Early Bird Badge airdropped;
🔸Odyssey for users has started, with over 50k users participating;
🔸Several ecosystem partner dApps have been tested;
🔸B² DA Layer has been explored.


These are progress updates related to the product, and we take pride in them. However, we also recognize that certain features need upgrades, and others must be added. Therefore, we have made the decision to launch our Beta testnet: Haven.

HAVEN implies a safe and sheltered place. In this stage, the testnet becomes a haven for users, a space where they can safely experiment and learn. Users can confidently try out and experience different aspects.

On Haven, we will:
🔸 Support our partners in launching more dApps for users;
🔸 Add more on-chain tasks to the Odyssey;
🔸 Integrate the EOA account, making it more convenient for users to use both EVM and BTC testnet addresses;
🔸 Launch B² Buzz to bring an in-depth financial experience to the B² Network for users.
This update is part of our ongoing commitment to improving the B² platform and ensuring a seamless experience for all users. Stay tuned for more information on the rollout of these changes.

Specifically, there are some changes and notices for users:
Address Compatibility:

For BTC addresses:

1. The B² beta testnet Haven will only support BTC testnet addresses.
2. The B² Mainnet, yet to be launched, will exclusively support BTC mainnet addresses.

For EVM addresses:

1. EVM addresses will remain unaffected by these changes.

Asset Mapping on B² Testnet:

Assets (NFTs/task points) associated with BTC mainnet addresses on the B² Testnet will be mapped to the corresponding BTC testnet addresses. The BTC mainnet/testnet address types must be consistent during the mapping process.

1. All points achieved with a BTC mainnet address can be transferred to the corresponding BTC testnet address automatically, provided it’s the same address type.
2. Haven won’t support any BTC mainnet addresses, so users holding BlockHeadz or Early Bird Badges need to check as follows:

• For BlockHeadz previously associated with BTC testnet addresses or EVM addresses, log in using the original BTC testnet address or EVM address to view them.
• For BlockHeadz previously linked to BTC mainnet addresses, log in using the corresponding BTC testnet address to access them (ensuring the address type remains consistent).
• Your BlockHeadz will automatically match. Click the link to check: https://blockheadz.bsquared.network
• OKX wallet users, if the NFT doesn’t appear in your wallet, please follow the instructions on the page to provide another wallet address to claim it. https://blockheadz.bsquared.network

3. EVM users can check NFTs with their original address without affecting their task points.
4. B² test BTC will be required, and we will provide the channel to obtain it. The claim will start soon after the launch of Haven.
This update is part of our ongoing commitment to improving the B² platform and ensuring a seamless experience for all users. Stay tuned for more information on the rollout of these changes.
