The bitcoin community shows more support to the user-activated-soft-fork (UASF) and BIP148 as Bitmain is accused of using a bitcoin code vulnerability to confront SegWit.

According to, the total number of nodes upgraded to BIP148 is nearing 300.

The Bitcoin Improvement Proposal 148, which contains mandatory SegWit activation, was published on 12 March by an anonymous developer under the alias shaolinfry. It is aimed not at miners but at nodes forcing them to upgrade to SegWit. A UASF of BIP148, which is, in fact, more of a hard fork, might be deployed as early as on 1 August, unless the consensus on SegWit activation is reached earlier.

Within the last week, the UASF/BIP148 support among nodes increased six-fold, from 50 to almost 300 nodes. The UASF/BIP148 share now accounts for 4.3% of the total number of bitcoin nodes.

BIP148 has been recently backed by the Litecoin project, tha head of which Charlie Lee recommended litecoin users to demand SegWit support from exchanges and wallets.


According to Coin Dance, the mandatory soft fork of BIP148 is backed by a number of crypto companies, including BitFury, BTCC, Bitcoin India, the exchanges service BitcoinReminder, the wallets BitPay, Samourai Wallet, and the bitcoin consulting company Freedom Node.

At the same time, according to NodeCounter, the main SegWit’s rival Bitcoin Unlimited still has many miners on its side. Among the last 1,000 bitcoin blocks, 342 signalled BU against 289 for SegWit. The key miners of BU blocks are Slush, BTC.TOP, ViaBTC,, GBMiners and the largest miner in the bitcoin network, AntPool.

Besides, BU is backed by the Chinese mining hardware producer Bitmain and its co-founder Jihan Wu. According to the bitcoin system developer Greg Maxwell, Bitmain uses the bitcoin code vulnerability known as ASICBOOST to generate excess profits and confront the SegWit activation.
