Ethereum just activated a major change called the ‘London hard fork’ — here’s why it’s a big deal – CNBC

Ethereum‘s much-hyped and somewhat controversial “London” hard fork has just activated.

So far, news of the successful upgrade has coincided with a runup in the price of ether, the native token of ethereum’s blockchain. The cryptocurrency is at $2,620, up 3.9% in the last 24 hours.

A big part of the enthusiasm has to do with the fact that the software upgrade means a few big — and necessary — changes are coming to the code underpinning the world’s second-biggest cryptocurrency. 

It has always been a tough go for ethereum users. The blockchain has a long-standing problem with scaling, and its highly unpredictable and sometimes exorbitant transaction fees can annoy even its biggest fans.

The problem has become worse in recent months thanks to a surge in interest in nonfungible tokens, which are mostly built on ethereum’s blockchain, as well as an explosive growth in the world of decentralized finance, or DeFi, which also largely uses the ethereum blockchain.

Thursday’s changes to the code, which has little to do with the city of London, are designed to fix many of these issues by destroying or “burning” ether coins and changing the way transaction fees work so that they are more predictable. 

If you think of ethereum like a highway, London is adding a few lanes to tamp down traffic and is standardizing toll prices. 

“It adds a lot of complexity to the fee logic, but it’s an interesting approach that could potentially stabilize the fee dynamics,” said Nic Carter, Castle Island
