Bitcoin glitch expected to abate as software upgrades continue
Bitcoin experienced a glitch over the weekend that is expected to be resolved as software clients that handle transaction data are upgraded.
Some software clients that “mine” bitcoins are creating invalid transaction data, which are referred to as blocks. Blocks are records of transactions, and the first miner to complete a block is rewarded with new bitcoins. The blocks are added to bitcoin’s public ledger, called the blockchain.
Some software clients that had not been recently upgraded are accepting invalid blocks created by other clients, according to a notice posted on bitcoin.org.
