TL;DR:

On June 8, 2026, Blockstream CEO Adam Back publicly dismissed the technical proposal identified as BIP-110.
The controversial initiative seeks to restrict non-monetary data in transactions through a user-activated soft fork (UASF).
The current support level of network nodes for the implementation of this protocol stands at low single digits.

Blockstream CEO Adam Back warned that a controversial proposal could trigger a Bitcoin chain split after categorically dismissing the BIP-110 initiative this past June 8, 2026. The entrepreneur called the approach technically flawed in a context where the debate over network governance reached a point of high tension within the community.

the reason it doesn't have consensus is it's stupid idea, doesn't work, and completely fails at technical consensus. polar opposite to segwit which did have technical AND ecosystem consensus (modulo a later stage attempt to abuse the activation process to veto what was agreed)

Industry rejection and comparison with SegWit

The proponents of the proposal argue that the measure would clean up the network by mitigating spam within the blockchain. However, according to Adam Back’s stance, in practice, this containment mechanism simply will not work. Additionally, the entrepreneur dismissed the parallels drawn between the BIP-110 scenario and the activation of SegWit in 2017.

In his statements, Back recalled that SegWit was consolidated after years of structural coordination among miners, developers, and node operators. Conversely, market data suggests that the current proposal lacks technical consensus and the backing of the crypto ecosystem.

Furthermore, Michael Saylor also spoke out independently regarding the status of BIP-110. From Saylor’s perspective, the initiative represents a direct threat to the protocol and shapes up as Bitcoin’s biggest self-inflicted risk at present.

Consequences of a Soft Fork without consensus

Enforcing a user-activated soft fork without the real support of the crypto community generates deep divisions. According to the analysis presented by Back, forcing this upgrade will result in a contentious minority fork rather than a legitimate upgrade of the global network.

To illustrate this argument, the executive posted the image of a feline bounded by blue tape under the label “DEFAULT OP_RETURN LIMIT.” The graphic details his view that BIP-110 attempts to establish an artificial boundary that the standard consensus process does not recognize.

Despite internal protocol disputes, Back’s stance regarding the crypto asset’s market value remains bullish. On June 9, 2026, the executive identified long-term investors as the steadfast actors within the market. Blockstream’s financial strategy continues to be grounded in sound money principles. The definitive outcome of this technical confrontation will be determined in the coming months, as the protocol’s activation window narrows and node support is evaluated.
