Michael Saylor Bitcoin protocol changes have become a hot topic in the crypto community after the MicroStrategy founder recently stated that attempts to modify the Bitcoin protocol represent the primary risk to the network in 2026. In his view, such initiatives, driven by what he calls “ambitious opportunists,” could pose a greater threat to Bitcoin’s long-term stability than external factors like regulatory pressure or technological disruptions. While Saylor did not point to specific projects or individuals, his comment has sparked widespread discussions around ongoing proposals like BIP-110 and the broader implications for how the Bitcoin network evolves.
Current Proposal: BIP-110
One of the main topics under discussion is Bitcoin Improvement Proposal 110 (BIP-110), put forward by the Bitcoin Knots development team. The proposal suggests a temporary soft fork that would set limits on the amount of arbitrary data included in transactions at the consensus level.
BIP-110 parameters:
- Data limit in transaction outputs — 34 bytes
- OP_RETURN limit — 83 bytes
- Duration — 1 year (with option for extension)
As of late January 2026, approximately 2.38% of nodes (around 583 out of more than 24,000 reachable nodes) are signaling support. Activation requires at least 55% consensus.
The proposal emerged following the Bitcoin Core v30 update in late 2025, which increased the OP_RETURN limit from 80 bytes to 100,000 bytes (configurable via the -datacarriersize parameter). This change enabled much larger data payloads, sparking varied opinions across the community.

Views from Key Community Figures
Adam Back (CEO of Blockstream) argues that the network already includes effective built-in safeguards against overload:
- Dynamic fees — users pay market rates for block space
- Proof of Work — makes large transactions (often tens of times bigger than standard ones) economically expensive
He highlights that these economic mechanisms help maintain balance without altering core protocol rules.
At the same time, critics of proposals like BIP-110 point out that users have historically found ways to bypass restrictions. For example, substantial amounts of data have already been embedded in the blockchain using alternative methods.
A similar idea appeared in BIP-444 (fall 2025), but it has not yet gained broad support.

What’s Next for the Network?
These discussions highlight the importance of balancing protocol stability with room for new applications in Bitcoin. The community continues to monitor node signals and review proposals in the relevant repositories.
