Blockchain network outages are not new within the crypto ecosystem. They affect higher-throughput, high-speed blockchains due to the increased technical complexity of these chains. Brief outages tend to be more common as the sophistication of blockchain networks increases and affects consumer confidence in cryptocurrencies.
Last August, TON experienced several brief outages thanks to the high demand for the DOGS memecoin. The DOGS minting created a network congestion that forced a chain halt.
However, the brief outages haven’t impacted the TON blockchain as it continues to attract new projects. Institutional investment in The Open Network is also on the rise as the team raised $400 million from venture capital firms, including Sequoia Capital, Draper Associates, CoinFund, SkyBridge, and others in March.
Toncoin (TON) is currently the 18th-largest cryptocurrency, with a market cap of $7.5 billion. TON is up by less than 1% in the last 24 hours and now trades at $3.15.
