So far, developers are calling ‘Spurious Dragon’ a success.
Ethereum’s latest hard fork, officially activated at block 2,675,000 today, comes days after the code was first tested as a solution to ongoing network performance issues. Among other changes, the fork will give developers the ability to delete empty accounts left by an unknown attacker that had effectively flooded the network.
While generally seen as a dangerous way to upgrade a blockchain (since it can lead to a network split if the proposed changes aren’t accepted by everyone), ethereum’s developers have embraced hard forks as a regular way to fix technical problems. This is ethereum’s third hard fork in the last four months.
While ethereum’s second fork was controversial, ending in two incompatible blockchains, the two most recent forks aim to address ongoing attacks on the network that have slowed down transactions and smart contracts.
Today’s hard fork further fine-tunes the prices of opcodes that the attacker abused to cheaply spam the network with transactions, contracts and accounts, that every node on the network needed to run.
‘Debloating’ the chain
While the upgrade doesn’t directly remove the empty accounts created by the attacker, it creates a way to “debloat” the blockchain.
