A latest report from Galaxy Analysis raises considerations concerning the long-term sustainability of Bitcoin’s Layer 2 (L2) scaling options, notably Rollups, which function a method of preserving transactions low-cost, quick, and decentralized. Very talked-about.
Regardless of the preliminary promise, the report means that these options might face financial challenges as a result of inherent limitations and prices related to Bitcoin block area.
Excessive value and restricted block area
Bitcoin’s block area is restricted to 4MB per block, a limitation that creates important challenges for aggregators searching for to leverage the community as an information availability (DA) layer. summaries, particularly these use Zero-knowledge (ZK) proofs intention to anchor their information to Bitcoin’s safe Layer 1 (L1) blockchain by publishing proof outputs and state variations each 6-8 blocks.
Nevertheless, publishing these information can eat as much as 400KB per transaction, equal to 10% of Bitcoin’s block capability. On condition that Bitcoin blocks have been full since January 2023, competitors for area might result in a spike in transaction charges that might be economically unsustainable for rollups and different customers.
that report emphasize Aggregation of DA utilizing Bitcoin would require producing important income from transaction charges on its community to cowl the excessive value of knowledge publication. For instance, publishing an aggregation of 400KB of knowledge each 6-8 blocks at a mean price charge of 10 sats/vByte might incur charges of roughly $460,000 per 30 days or roughly $5.5 million per 12 months.
If charges rise to 50 sats/vByte, these prices might soar to $2.3 million per 30 days, totaling about $27.6 million per 12 months. To interrupt even, rollups require numerous customers keen to pay transaction charges of $0.05 to $0.23, relying on the speed setting.
Substitute DA layer and reorganization
Given these monetary pressures, the report means that Rollups might must discover different DA options similar to Celestia, Close to, or Syscoin, which supply cheaper choices. Nevertheless, this would scale back the consistency of Rollups with Bitcoin, probably turning them into Validium chains fairly than true BTC Rollups.
One other potential resolution is to restructure the sum right into a layer 3 resolution, publishing the state variations to current layer 2 or sidechains. It will scale back information publishing prices whereas sustaining some connectivity to the Bitcoin community.
The conclusion of the report is future The dimensions of Bitcoin aggregations will rely on their means to stability the excessive prices of leveraging cybersecurity infrastructure with the necessity to entice customers and generate ample income.
