Bitcoin Network Policy & Market Dynamics - Node policy changes are reactive to network and market conditions, not consensus changes [2] - Market demand and miner willingness to mine transactions override filters, even for minority interests [2] - Organic user demand can significantly impact block composition, as seen with sub 1 satoshi/virtual byte transactions reaching up to 70% of some blocks [2] OP_RETURN Data & Incentives - The current network relays and mines data regardless of OP_RETURN size (80, 160, or 100kb), making size adjustments socially contentious rather than technically or economically effective [4] - There's little incentive for using larger 100kb OP_RETURN due to being 4x more expensive [3] Solutions & Mitigation - Economic solutions, such as cheaper data availability OP_RETURN with incentives for miners, are proposed as a potential solution [5] - Soft forks to limit IP return to 160 or 80 bytes are suggested, but inscriptions may be tricky to limit via soft fork [5] - Hiding data in fake pubkeys is a potential workaround for spam filters [5] Data Inscription & Validity - Contiguous data can be sent in inscriptions, utilizing Taproot segment separators [1] - 1Mb contiguous data in OP_RETURN has been consensus valid since 2014 [1]
