  "map_content": "Ethereum L2s (shared, posting to L1 via EIP\u20114844)\n- Typical fee today for a simple write: ~$0.0005\u2013$0.02 per tx (can be lower/higher depending on blob market and chain).\n- Daily cost at 1000 tps:\n  - $0.0005/tx \u2192 ~$43,200/day (~$1.3M/month)\n  - $0.002/tx \u2192 ~$172,800/day (~$5.2M/month)\n  - $0.01/tx \u2192 ~$864,000/day (~$26M/month)\n- Capacity caveat (the big one): EIP\u20114844 blob space is limited per L1 block. At current parameters (target ~3 blobs/12s, max ~6; ~128 KB per blob), the network\u2011wide 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\u201350 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.",
