Avalanche network endures temporary block production halt.
Avalanche blockchain fell into an unexpected failure mode.

The Avalanche blockchain platform experienced a sudden stall in new block creation on its C-Chain subnet according to online monitoring as of February 23, 2024. Avalanche's core subnet facilitates creation and trading of native AVAX tokens along with custom assets and apps.

Key Takeaways:

  • Avalanche network endures temporary block production halt on core C-Chain.
  • Issue related to non-finalization of the last block, causing stalling.
  • Avalanche developers are actively investigating the root cause.
  • Network previously maintained uptime through all market conditions since launch.

Avalanche Blocks StallThe blockchain analytics site Avaxmate indicated no new validated C-Chain blocks have been produced for over an hour at time of writing. The last finalized block height peaked at #13,607,242 with a timestamp logged on Friday, February 23 2024 17:34 UTC.

In the hour since, no further blocks have been ratified on the network. The issue relates to non-finalization of the last processed block batch. This subsequently halted creation and settlement of additional transactions across Avalanche.

Avalanche Developers Investigate Stall

Following online reports of the apparent Avalanche stall, core developers communicated through Discord that they have been made aware of the disruption and are presently investigating root causes.

Lead Avalanche developer Gabriel Cardona stated:

"We are taking a look into this right now and hope to have more info shortly."

No further technical explanations have yet been provided by Avalanche team members regarding specifics of the stoppage. There also remains no estimated timeline communicated for restoring normal blockchain functionality.

However the collaborative investigation underway suggests developers are actively working to address the lingering block finality failure affecting core network operations.

History of Robust Uptime Claims

Notably, the Avalanche foundation has historically touted its network's resilience and stable uptime spanning years of live usage across changing market conditions:

"Avalanche has been running continuously for over 2 years without downtime making it one of the most battle-tested platforms in crypto with an uptime greater than that of Amazon Web Services (AWS)."

Whether today's apparent processing stall impacts these claims of superlative uptime remains unclear until developers provide more details.

Nonetheless it marks the first known instance of Avalanche encountering this variety of failure mode compared to prior achievements. Hopefully the coding issue proves relatively minor and straightforward to rectify.

Introducing Avalanche

The Avalanche network first launched mainnet functionality in September 2020 after an extensive whitepaper peer review process and multiple years of private testing work building out its complex protocol architecture.

Avalanche TransactionsIt represented an ambitious effort to transcend perceived limitations of older blockchains like Bitcoin and Ethereum through novel technical optimizations. In particular, Avalanche emphasizes blazing transaction finality measured in less than a second while maintaining decentralization and security assurances with thousands of validators.

Additional touted strengths cover high throughput capacity exceeding 4,500 transactions per second along with native support for Ethereum Virtual Machine compatibility allowing portability of Solidity based dApps.

The network likewise facilitates low cost activity via its C-Chain and flexible custom subnet creation for supporting all manner of programmable distributed apps spanning DeFi, NFTs, gaming/metaverses and more.

Over its lifespan, Avalanche has built substantial adoption momentum to rank among top 10 largest cryptos with a market cap exceeding $4 billion. However the current uncertainty may generate short term doubts if not soon resolved.


In summary, the Avalanche core blockchain has fallen into an unexpected failure mode as of February 23 2024 with block finalization stalling that has halted further transaction settlement or asset activity. Avalanche engineers actively diagnose the technical hitch.

While breaching prior uptime assurances, hopefully mechanisms like validator voting can mitigate lasting repercussions of today's outage events pending official updates. Until reliable functioning gets reestablished however, user funds and activities remain frozen - jeopardizing its competitive standing.
