From 0 to 1000 Nodes on a Testnet: Case Study on Avalanche Denali

What is a testnet?

A Testnet is a network for running tests. Its utility is to perform tests and run experimental features before the project goes into production. The testnet is a sandboxed environment for improvements and optimizations, before deploying them on the mainnet.

What is Avalanche?

Avalanche is an open-source platform for launching highly decentralized applications, new financial primitives, and new interoperable blockchains. It is a dedicated platform for the development of tokens and decentralized applications.

What is the incentive testnet Denali?

The Denali testnet is the third Avalanche testnet; the first two were Borealis and Cascade.

The Denali testnet in figures

  • More than 1050 nodes and block validators
  • More than 47 countries with at least one node
  • 15 days of incentive testnet
  • 5 versions of testnet Denali deployed
  • 11 blockchains created
  • 159 tokens created on Avalanche
  • 16 subnets
  • The GitHub activity during the Denali testnet per repository: More than 222 commits during the incentive period.
  • 90 commits on Gecko
  • 42 commits on Ava Explorer
  • 42 commits on doc ava
  • 4 commits on Avash
  • 28 commits on Slopes
  • commits on ortelius
  • commits on ava-quicksign

What issues did Avalanche face? How did they solve them?


How did Avalanche successfully engage with a high number of participants?

To attract a large number of participants to the Denali incentive testnet, Avalanche set a 2,000 Avalanche reward for the first 1,000 validators. Emin Gün Sirer, Avalanche’s well-known CEO, engaged with his large Twitter following to raise awareness to support the Denali incentive program. The team was committed to helping all the participants and developers.

What are our thoughts on the Denali testnet event?

Denali was a huge success:

  • It was the only network we can think of to engage with a large node operator community on its testnet
  • The testnet prepared Avalanche to what could happen during his mainnet
  • Avalanche team manage to do a network upgrade in a very short timeframe and fix issues
  • It showed the efficiency of Avalanche support
  • Avalanche’s team engaged with community members, node operators, and developers

How did ablock contribute to the success of Denali?

We wanted to help the community participate in this event. We thought about what could help a newcomer join this testnet in the most straightforward way.
