Aptos said its first Testnet (blockchain testing network) state reset will take place on Oct. 7, restarting the network from a new genesis block (initial blockchain block). Existing deployed contracts, test accounts, balances and historical data will be erased, requiring applications to be redeployed. Aptos said the Testnet has processed more than 10 billion transactions, while its expanding state storage has prompted the periodic-reset approach set out in AIP-147. The operation will not affect Mainnet or Devnet.
