LACNet is an international non-profit association that results from the alliance between RedCLARA and LACNIC in collaboration with IDB Lab. LACNet has been created by the LACChain Global Alliance to orchestrate the LACChain Blockchain Networks guaranteeing neutrality and sustainability. Currently, LACNet orchestrates three networks: Legacy Protestnet, Open Protestnet and Mainnet Omega.
There are currently two different environments available to deploy your node:

  • Open Protestnet (free): Testing environment for Mainnet compatible solutions.
  • Mainnet Omega (membership required): Production environment for enterprise-grade solutions.

Please note that the Legacy Protestnet (deprecated) is only available to members who deployed a node before October 10th 2022. For development and testing purposes please also consider deploying a node locally.
To learn more about the different environments please see here.
The hardware specifications for your node can be found here.
We have developed guidelines to deploy a node using Ansible, Docker and Kubernetes
In the event of technical issues while deploying a node please check here if the issue has already been addressed.  If you are operating in the Protestnet (any) you could also raise an issue on GitHub. If you are operating in Mainnet Omega please open a ticket in our client portal for individual support. 
You should consider your node as another component of your digital infrastructure. Therefore, you must provide it with the same type of protection, including firewall security layers, activity monitoring, and backup.  Codewise please look at the following Hyperledge Besu recommendations for authentication.
The sync process time depends on both the size of the blockchain and hardware capabilities of the node. Please see below current estimated times on the different environments:

  • Legacy Protestnet: 7 days.
  • Open Protestnet: 4 hours.
  • Mainnet Omega: 1 day.

Deploying a smart contract in the Open Protestnet or Mainnet Omega environment requires adjusting your contract to our GAS distribution protocol. Please look at the following guidelines for more information. If you already have experience working with smart contracts, please find below different tutorials and examples depending on your coding requirements and preferences:

Please note the Legacy Protestnet (deprecated) does not required adjusting your contracts to the GAS model, therefore they can be deployed as in the Ethereum Network, setting the gas price to zero.
Once a contract has been deployed you will get a confirmation and the contract address on your development console. Then you could inspect the contract by using our blockchain explorer below. At the moment this feature is only available in the Legacy Protestnet explorer.

To find out how much gas your transaction consumes please follow the steps below: 

  1. Submit a transaction and get the transaction Id.
  2. Then search for your transaction using the following API.
  3. As a response you will get a “gas” parameter with a hexadecimal value.
  4. Please convert to decimal to know how much GAS your transaction consumed.

Alternatively, you could also use the following table as a reference for your estimate:

Memberships  Basic  Standard  Premium 
Monthly fee  $170  $380  $1.250 
Gas available per block   500.000  1.500.000  4.000.000 
Block time   2s  2s  2s 
Estimated Gas required to issue a Verifiable Credential   275.000  275.000  275.000 
Estimated Verifiable Credentials issued by block   1 5  14 
Estimated Verifiable Credentials issued per second  0,91  2,73  7,27 
Estimated Verifiable Credentials issued per minute    55    164    436 
Estimated Verifiable Credentials issued per hour  3.273  9.818  26.182 
Support hours (Mon-Fri, 8hs)  Si  Si  Si 
Extended support  No  No  Si 
The space required for each block range from 1KB to 3MB.
New blocks are added to the chain every 2 seconds on average. 
To schedule a batch upload or any other one-off activity that requires more gas than included in your membership please contact [email protected].
Any Ethereum compatible wallet (e.g., Metamask) could be used to interact with LACChain through your node.
To access your node remotely please open /lacchain/config.toml and uncomment the following lines:

# host-whitelist=["*"]
# rpc-http-host=""
# rpc-http-cors-origins=["*"]
To allow webSockets connections please add the following line:


Finally, restart the service by running the following command:

> service pantheon restart
Please send us the new e-node so we can update our registries. Then open /lacchain/config.toml and update the following line:

# Networking
p2p-host="<new IP address>"

Finally, restart the service by running the following command:

> service pantheon restart
It might occur the node ran out of storage space. Please make sure there is enough space to complete the synchronization and restart the services.
In that case, it might occur the node has not finished synchronizing. Please wait until the blockchain synchronization is completed and try deploying the smart contract again. 
LACNet is limited to offering blockchain infrastructure orchestration services. However, LACChain has a set of partners and a large community of entities that support the development of solutions and projects.
