Validators decided to halt chain operations on Thursday in anticipation of governance attacks as the LUNA token plunged over 99%.

Validators for the Terra blockchain have decided to officially halt network activity on Thursday in a move designed to prevent governance attacks following the severe devaluation of the network’s LUNA token. 

Terraform Labs’ official Twitter handle confirmed that the blockchain network was halted at a block height of 7,603,700. The move follows a series of dramatic events that triggered an unprecedented decline in the price of LUNA and its associated TerraUSD (UST) stablecoin. The stablecoin, which was designed to maintain algorithmic parity with the United States dollar, lost its peg earlier this week before plunging below $0.30.

Terra validators have decided to halt the Terra chain to prevent governance attacks following severe $LUNA inflation and a significantly reduced cost of attack.

With LUNA’s price collapsing more than 99%, Terraform Labs is no longer confident that it can prevent governance attacks. In other words, the price decline “significantly reduced [the] cost of attack,” the ecosystem operator tweeted Thursday. 

As Cointelegraph reported, LUNA/UST contracts are slated for delisting on Binance once the trading pair falls below 0.005 USDT, which has already occurred. The delisting took place on Thursday at 3:30 pm UTC.

Earlier this week, Terraform Labs co-founder Do Kwon shared details about a recovery plan that would help save the UST peg from further devaluation. Terra’s official Twitter handle further elaborated on those plans on Thursday by laying out a strategy to burn $1.4 billion UST and stake 240 million LUNA. However, the details of the rescue plan have failed to deter market sell pressure.

The primary obstacle is expelling the bad debt from UST circulation at a clip fast enough for the system to restore the health of on-chain spreads.

Before the events of this week unfolded, Terra LUNA was a top-ten cryptocurrency project by market capitalization and its UST asset was the third-largest stablecoin behind only Tether (USDT) and USD Coin (USDC).
