It’s no longer just about proving something happened on-chain. The real question now is: when did it happen, and did it happen within the rules of the protocol? That’s exactly where $SIGN latest direction especially around ePBS—starts to matter.To understand why this is trending in 2026, you have to look at Ethereum’s move toward proposer-builder separation, specifically ePBS (enshrined PBS). One of the biggest upgrades here is the introduction of a Payload Timeliness Committee (PTC), which effectively judges whether execution payloads are delivered on time within each slot. In simple terms, blocks are no longer just “valid or invalid.” They can now be classified as full, empty, or even missing depending on whether the payload arrives on time. That subtle shift changes everything for data protocols like Sign. @SignOfficial is adapting by indexing new gossip-layer data, particularly the payload_attestation_message stream. This is where validators broadcast real-time attestations about payload timing. Instead of treating attestations as static proofs, $SIGN is evolving them into something more dynamic time-aware, context-rich signals. This is where the idea of “timeliness grading” comes in. From a trader’s perspective, that’s a big deal. It introduces a new layer of trust: not just did it happen, but did it happen correctly within protocol expectations?Think about MEV-sensitive environments or cross-chain messaging. Timing delays can mean the difference between valid execution and economic loss. With ePBS, timing is now part of consensus reality. And Sign is positioning itself to capture that signal early.What’s interesting is how fast this narrative is gaining traction. Over the past few months, developer discussions have increasingly focused on gossip-layer observability and real-time indexing. The fact that Sign is already experimenting with these data streams suggests it’s not waiting for full mainnet standardization it’s building ahead of it.
