Announcing Helium (v0.3.3) for go-canxium: Enabling Cross-Chain Mining with Kaspa

2 min read2 days ago

We are excited to introduce Helium (v0.3.3), the latest release for go-canxium. This update marks a major milestone in Canxium’s development, activating cross-chain mining with Kaspa and reducing the contract creation fee to 1 CAU.

🚀 Key Features in Helium (v0.3.3)

1. Helium Hardfork Activation

The Helium hardfork will activate on March 1, 2025, at 12:00 AM UTC (timestamp: 1740787200). This upgrade is essential for enabling Canxium’s cross-chain mining capabilities and optimizing transaction fees.

2. Cross-Chain Mining with Kaspa

With Helium, Canxium officially integrates cross-chain mining with Kaspa, allowing miners to earn CAU alongside KAS. This feature is designed to increase Canxium’s visibility and adoption within the Kaspa mining community, driving further growth and decentralization.

3. Lower Contract Creation Fees

Smart contract deployment on Canxium is now more affordable than ever, with the contract creation fee reduced to 1 CAU. This change makes it easier for developers to build on the Canxium blockchain and expand the ecosystem.

🔧 How to Upgrade Your Validator Node

To ensure a smooth transition, follow these steps to update your validator node:

Checkout go-canxium v0.3.3

git checkout v0.3.3

2. Compile go-canxium

make canxium

3. Stop the existing go-canxium process

systemctl stop node

3. Initialize the new genesis block

canxium --datadir=/canxium/chain --db.engine=pebble init /canxium/go-canxium/genesis/mainnet.genesis.json

4. Restart go-canxium

systemctl start node

If you have installed your node using our script, just run this one command

cd /canxium/go-canxium/ && git pull origin main && git fetch && git checkout v0.3.3 && make canxium && systemctl stop node && /canxium/go-canxium/build/bin/canxium --datadir=/canxium/chain --db.engine=pebble init /canxium/go-canxium/genesis/mainnet.genesis.json && systemctl start node && journalctl -f -u node

✅ Verify a Successful Update

After restarting, check the logs to confirm the upgrade:

journalctl -u node -f

If you see the following logs, your node is correctly updated:

canxium[519162]: INFO [02-19|07:18:45.676] Post-Merge hard forks (timestamp based):
canxium[519162]: INFO [02-19|07:18:45.676]  - Shanghai:                    @1723122376
canxium[519162]: INFO [02-19|07:18:45.676]  - Helium:                           @1740787200
canxium[519162]: INFO [02-19|07:18:45.676]
canxium[519162]: INFO [02-19|07:18:45.676] Merge Mining configured:
canxium[519162]: INFO [02-19|07:18:45.676]  - Kaspa:                      @{false [100000000000000]}

This means your node is now ready for the Helium hardfork and cross-chain mining.

🌍 What This Means for Canxium’s Future

The Helium upgrade is the next step in Canxium’s roadmap towards greater interoperability and miner adoption. By enabling cross-chain mining with Kaspa, we’re tapping into one of the largest PoW mining communities, further strengthening Canxium’s network security and adoption.

We are committed to making Canxium a decentralized, efficient, and widely adopted blockchain. With Helium, we are moving closer to that vision.

Thank you for your support, and let’s build the future of PoW together! ⚡
