RT Mechanic #FixTheFilters #300kb (@GrassFedBitcoin)First they came for the non-monetary UTXOs and I did not care because my UTXOs aren't obviously trash all suspiciously sitting just above the dust limit.Then someone suggested doing the same for monetary UTXOs in order to comply with a government blacklist and no one went along with it because Bitcoiners aren't as stupid as Coretards like to pretend they are. ...

RT ₿itcoinMonk | ₿itcoin Signal (@BitcoinMonk21)Wake up bitcoiners, Run knots!!!This big beautiful consolidation transaction has been in my mempool for the last six blocks and was actually rejected by Foundry USA 3 times, viaBTC, and Binance in favor of a bunch of garbage spam. This is where core 30 is taking us. Core nodes now favor bloating the utxo set over shrinking it.My knotty node has been trying to mine this transaction the entire time but it was displaced by spam that core 30 is optimized for. Why ...

RT Satflation⚡ (@satflation)I scrolled by @mononautical post about weird frog gif stored on chain and saw “less than a hundred bucks!”Newbies to spam dynamics like myself may not understand this type of “transaction” burns all outputs, sending UTXOs to unspendable addresses.In other words, it cost a whopping ~$840, once we include the 613,470 sats burned (1,859 outputs of 330 sats). What misleading garbage!The UTXO set is harmed, creating 1,859 outputs that will never be spent.But the spammers get wrecked, ...

Transaction Analysis - A specific on-chain transaction involving a "weird frog gif" cost approximately $840, including the burning of 613.47 thousand sats [1] - The transaction burned 1.859 thousand outputs of 330 sats each, sending UTXOs to unspendable addresses [1] Impact on Bitcoin Network - The burning of UTXOs harms the UTXO set by creating 1.859 thousand outputs that will never be spent [1] - HODLers benefit from a 0.000000029% deflation due to these burns [2] Comparison with OP_RETURN - This type of spam transaction is costly for the perpetrators, unlike OP_RETURN transactions [2] - OP_RETURN allows storing larger images for a lower cost, such as $120, without burning any UTXOs [2]
