On May 23, Barry Silbert-led Digital Currency Group (DCG), arguably the biggest bitcoin and blockchain industry investment firm, announced that miners and businesses had reached a consensus to bitcoin’s seemingly never-ending scaling debate. Parties involved in the agreement represented 83.3 percent of the network’s hashing power, 20.5 million bitcoin wallets, and a 5.1 billion on-chain transaction volume.
Yeah, this isn't the first "agreement". So far, every agreement has been backed out of in some way.
In this case, that's a good thing because segwit is govt/bankers poison pill to make bitcoin into a settlement layer for the govt/banks Layer 2 network which will basically be paypal with all the KYC/AML to use bitcoin.
Looks like there is a lot of work being done behind the scenes to force a chain split. One coin will be shitty 1MB Segwit coin, the other will be unlimited blocksize Bitcoin.
