LONDON, Sept 12 (Reuters) – A long-awaited software upgrade to the Ethereum blockchain aimed at slashing its huge energy consumption is expected this week, a move proponents say may widen the technology’s use and support the price of the ether token. 

The upgrade, known as the “Merge,” will mark a radical change to how transactions on the Ethereum blockchain occur and ether tokens are created. The new system will consume 99.95% less energy, according to the Ethereum Foundation, a body which acts as a spokesperson for the network.

Oil Prices Rise As Uncertainty Mounts

LONDON, Sept 12 (Reuters) – Oil prices rose on Monday as Iranian nuclear talks appeared to hit obstacles and an embargo on Russian oil shipments loomed, with tight supply struggling to meet still robust demand.

Brent crude futures rose 92 cents, or 1%, to $93.76 a barrel by 0910 GMT. U.S. West Texas Intermediate crude was up 71 cents at $87.50 a barrel, or 0.8%.

Prices were little changed last week as gains from a nominal supply cut by the Organization of the Petroleum Exporting Countries and allies including Russia, a group known as OPEC+, were offset by lockdowns in China, the world’s top crude importer.
