According to Farside Investors (@FarsideUK), Bitcoin node operators can cut exposure to bandwidth and resource exhaustion by using a firewall, running blocksonly mode, setting a data upload cap, and restricting mempool size, which are practical steps to keep nodes online during high-load events, source: Farside Investors on X. Bitcoin Core documentation explains that -blocksonly disables transaction relay, -maxuploadtarget caps daily outbound bandwidth, and -maxmempool limits memory usage, reducing the risk of node outages during traffic spikes that can disrupt market connectivity, source: Bitcoin Core documentation. Bitcoin Core documentation also indicates that blocksonly mode reduces visibility into unconfirmed transactions, a trade-off trading desks relying on mempool data should evaluate when configuring nodes, source: Bitcoin Core documentation.
