The last few weeks at Sentinel have been exciting with a lot of updates to the client and the node. The team is preparing for the upcoming dVPN Desktop App release and has released an update for the node. After fixing a few of the issues that the network currently has, a new version of the node has been released on both Ethereum (v0.0.7-alpha) and Tendermint (v0.1.3-alpha). Existing dVPN TestNet nodes are required to update as soon as possible to support the latest features.

Users are welcome to setup a dVPN Node to share bandwidth to the Sentinel TestNet on Ethereum. Sentinel dVPN node installation instructions for Ethereum can be found here. Information on the latest version of docker can be accessed from the Docker Hub.

What’s new?

The latest release of Sentinel’s dVPN Node contains updates to both the Ethereum Node and the Tendermint Node.

Release notes, of the update, for both TestNets is mentioned below:

Ethereum (v0.0.7-alpha):

  1. OpenVPN Index File Error has been fixed
    Nodes that generated over 6000 keys had an issue where the OpenVPN index file with those keys wasn’t being updated. Nodes were required to restart the instance/docker earlier to fix this issue. A fix has been released to ensure that the node clears keys after the end of a session.

Instructions to install or update the node can be found here.

Tendermint (v0.1.3-alpha)

  1. Removed the 1GB Limit to accommodate locking of any number of token
    In order to combat spam on the ETH node, the max session limit is set to 1GB. On the Tendermint TestNet, there is no limit on the total data that can be used as a variable number of tokens can be locked as required.
  2. Enabled ‘max upload’ and ‘max download’ data
    Owing to variable tokens being locked, the maximum data that is to be uploaded and downloaded is decided based on total tokens locked by the user for a specific session.
  3. Updated to the latest Sentinel CLI (command line interface)
    The Sentinel TM Node has been updated to the latest version of the Sentinel CLI with an improved interactive installation setup.
  4. Fixed ‘Signature Verification Error’ for a transaction
    Previously, there was a ‘signature verification failed’ error when the VPN node had to claim payment. This was due to the wrong signature being used by the VPN node. The same has been fixed in the current release.
  5. OpenVPN Index File Error has been fixed
    Nodes that generated over 6000 keys had an issue where the OpenVPN index file with those keys wasn’t being updated. Nodes were required to restart the instance/docker earlier to fix this issue. A fix has been released to ensure that the node clears keys after the end of a session.
Quick overview of the updates to the Sentinel dVPN OpenVPN Node on both Ethereum and Tendermint TestNets

Currently, hosting of Tendermint Nodes is only for select Service Providers that have done the same for Ethereum. Hosting of Tendermint OpenVPN nodes will be open for the entire community in the month of February.

We would like to take this opportunity to thank the Sentinel community for continuing to support the Sentinel Network. Your efforts in running Sentinel TestNet Nodes are invaluable for the development of tested and proven technology at the forefront of the privacy revolution.

About Sentinel Network

Sentinel Network is a network layer that enables a true p2p and decentralized applications and resources marketplace. Sentinel enables anyone to create Public and Private networks that provide access to both free and incentivized, and also payment method agnostic (pre-paid/escrow/post-paid) services (dApps) & distributed resources, enabling its clients to become both producers and consumers in the network.

Sentinel utilizes locking, staking and multi-sig directly from Tendermint core and Cosmos SDK and aims to fully eliminate the disadvantages of previous generation protocols, that couldn’t scale due to limitations of the blockchain they share with other dApps or that have an unsustainable economic model that reduces usability or access to the product they offer.
