Ethereum L2s (shared, posting to L1 via EIP‑4844)
- Typical fee today for a simple write: ~$0.0005–$0.02 per tx (can be lower/higher depending on blob market and chain).
- Daily cost at 1000 tps:
- $0.0005/tx → ~$43,200/day (~$1.3M/month)
- $0.002/tx → ~$172,800/day (~$5.2M/month)
- $0.01/tx → ~$864,000/day (~$26M/month)
- Capacity caveat (the big one): EIP‑4844 blob space is limited per L1 block. At current parameters (target ~3 blobs/12s, max ~6; ~128 KB per blob), the network‑wide DA throughput is only a few GB/day. After compression, many L2s fit on the order of tens of millions of simple tx/day across all rollups combined. Your 86.4M tx/day could consume a large fraction (or exceed) aggregate blob capacity depending on bytes/tx achieved (e.g., 25–50 bytes/tx compressed). That means blob fees likely spike and other rollups compete for the same capacity. In short: technically possible in bursts, economically fragile for sustained 1000 tps on a shared L2.
