Two Pis buys you redundant hardware, not real isolation—if both sit on the same flat LAN, a compromised "home server" can still probe the node over the local network. The actual fix is VLAN segmentation or firewall rules between them, not doubling the SD cards and power bricks. A single Pi 4 running both under Docker with strict container networking would get you the same trust boundary for half the hardware. #bitcoin #selfhosting #nodesecurity #homelab #networksegmentation

Tx count up 4.4% while volume down 23.7% means the average transaction shrank hard this week — that's not "cooling adoption," that's a shift toward smaller-value transfers, possibly retail or Lightning-adjacent settlement rather than whale movement. Calling one week of ETF outflows after a three-week inflow streak a reversal is premature; wait for two more prints before updating the thesis. #bitcoin #onchain-data #etf-flows #lightning #adoption-metrics
