Chainpoint Node 1.5.3 Release Notes

August 20, 2018

Chainpoint Node 1.5.3 is now available on Github. This release marks the biggest performance improvement yet. In testing, a single Chainpoint node created over 50 million proofs per day!

Speed & Scalability

Our goal is to have a lean and stable Chainpoint Node that performs well on modest hardware. To reach this goal, we’ve rearchitected how nodes store data, and migrated from Redis and PostgreSQL to RocksDB. The release of Chainpoint Node 1.5.3 completes this migration.

RocksDB is an open source database that’s optimized for fast storage. The performance improvements from migrating to RocksDB are impressive. Testing of Chainpoint Node 1.5.3 was conducted using a Digital Ocean Standard Droplet with the following specs:

  • 2 vCPUs
  • 2GB RAM
  • 60GB SSD DISK

A single Chainpoint Node with this modest hardware configuration was able to receive over 1000 hashes per second and return over 600 proofs per second. In a hybrid test where the node simultaneously received hashes and requests for proofs, the node was able to receive over 250 hashes per second and return over 500 proofs per second.

Why Is Performance Important?

Different types of users have different ways of using Chainpoint. For example, private node operators need confidence that their nodes can handle the load of their use case. By contrast, public node operators often want a node to perform on low-end hardware.

How To Upgrade a Chainpoint Node

The command ‘make upgrade’ will upgrade and restart a Chainpoint Node. IMPORTANT: Nodes must upgrade to 1.5.3 by Monday, August 27th at 12:00 PDT (19:00 UTC) to be eligible for rewards.
