Aisea Aisea Bitcoin Tetee i Tusitala?
One of the central value propositions of Bitcoin is that no matter what happens, if you pay a high enough fee some miner out there in the world will confirm your transaction. In other words, Bitcoin is censorship resistant. There is a very good reason that the phrase “censorship resistant” is the wording you hear whenever this topic comes up, not “censorship proof.” Any individual miner can censor whatever they want, in the sense that they can refuse to include something in any block they mine themselves. They cannot, however, prevent other miners from including that transaction in their own blocks whenever they find one.
Bitcoin is resistant to censorship, but it is not immune to it. Any miner can censor whatever they want, and that is free, ignoring of course the potential opportunity cost of revenue loss if there are not enough transactions available paying a comparable feerate to the transaction(s) they choose to censor. But this doesn’t stop the global system from processing that transaction anyway, unless those miners 1) comprise a majority of the entire network hashrate, 2) choose to leverage that reality to orphan the block of any miner who chooses to process the transaction(s) they wish to censor.
O le faia o lenei mea o le a leiloa ai le toʻatele o tagata maina o loʻo auai i tupe osofaʻiga a tamaiti matuaoti pe a faʻaauau pea e le vaega toʻaitiiti o miners poloka poloka e aofia ai le fefaʻatauaʻiga "verboten". O taimi uma lava e maua ai sea poloka, o le a matua faateleina ai le taimi seia oʻo i le isi poloka na faia i totonu o le filifili e maua, faʻaititia ai le tele o le faʻasalaina o tupe maua a le au maina i le averesi. O le a tumau pea le tulaga lea seia oo ina fiu le vaega toalaiti ma toilalo pe leai foi ni pisinisi (ona o le a latou lafoaia tupe maua i soo se poloka e aofia ai ma le faʻasalalauga faʻasalalau).
For now, let’s assume that this scenario is not in the cards. If it were, Bitcoin is either a failure, or must exist in this state until non-censoring miners are able to quietly amass enough hashrate in order to overpower the current majority intent on orphaning blocks containing transactions they do not want confirmed in the blockchain.
O le a la le mea e tupu pe a filifili se seti o miners, i le toʻaitiiti, o le a latou faʻasalaina se vaega patino o fefaʻatauaiga mai a latou poloka? O le aofaʻi o poloka poloka o loʻo avanoa mo na fefaʻatauaiga e faʻaitiitia. E itiiti le poloka avanoa avanoa mo i latou nai lo isi vasega uma o fefaʻatauaiga. O le a le iuga o lenei mea? O le mamafa o totogi mo lenei vasega o fefaʻatauaiga o le a sili atu le vave o le saturation nai lo isi vasega uma o fefaʻatauaiga.
Naʻo le faʻafaigofie i le faʻataʻitaʻiga, mafaufau e naʻo le 10 fefaʻatauaiga e faʻatumu ai soʻo se poloka. Matou te taʻua fefaʻatauaiga masani na o "fefaʻatauaʻiga masani", ma o fefaʻatauaiga o loʻo faʻasalaina "faʻatauga faʻatau." O aso taʻitasi e tusa ma le lima poloka e maua, ma e toʻalima tagata eli. O poloka mumu o loʻo faʻatusalia ai tagata maina e le mafai ona laʻuina fefaʻatauaʻiga verboten, ma o poloka lanu meamata o miners latou te faia. Mo fefaʻatauaʻiga masani e faʻamalieina ai le avanoa avanoa ma amata faʻaosoina totogifuapauina, e manaʻomia le 50+ fefaʻatauaiga o loʻo faʻatali ina ia mafai ai e le faʻalavelave tauofo ona amata faʻaosoina totogifuapauina ma faʻateleina tupe maua mo miners. I le taimi nei o le totogifuapauina na maua ai tupe maua mo uma o le a amata ona faateleina le au maina.
Mo fefa'ataua'iga fa'atauva'a, e na'o le 20+ fefa'ataua'iga e mana'omia ona fa'atali ina ia mafai ai ona amata se fa'atauva'a i totonu oi latou, fa'ateleina tupe maua. Ae o le totogifuapauina o tupe maua mai le verboten transactions o le a na'o le aoina mai e le au miners lanu meamata.
I se tulaga o fefaʻatauaiga verboten e le o saturating mempools e sili atu i le malosi poloka o loʻo avanoa mo i latou, o le a faia e miners uma le tulaga tutusa o tupe maua. O na fefaʻatauaiga faʻatauvaʻa e tatau ona tauva ma fefaʻatauaiga masani ina ia maua ai se faʻamaoniga o le faʻamaonia taimi, o lea afai o fefaʻatauaiga masani o loʻo tumu i le mempool ae o fefaʻatauaiga faʻatau e le o le aofaʻi o le mamafa o le totogi o le a faʻasoa tutusa i le va o tagata maina uma ma e leai se tasi e le tutusa. totogifuapauina tupe maua e le maua i isi.
Ae peita'i, afai o fefa'atauaiga verboten o lo'o fa'atumuina ai le mempool e sili atu nai lo le avanoa avanoa, o le mamafa o le totogifuapauina o le a fa'aosoina ai totogifuapauina totogi e fefa'atauaiga verboten. na'o tagata eli lanu meamata. O le filifilia e fa'amaonia nei fefa'ataua'iga, o le a le iloa e le 'au mina mumu so'o se fa'aopoopoga o tupe maua mai le fa'atauga fa'atau. O fefaʻatauaiga masani i lenei faʻataʻitaʻiga o le a le tatau ona tauva ma fefaʻatauaiga verboten i totogifuapauina seivagana ua latou manaʻomia le faʻamaonia i le isi poloka, o le mea lea o le siitaga le tuusao i luga o fefaʻatauaiga masani ona o le mamafa o totogifuapauina o fefaʻatauaiga o verboten o le a le taitai atu ai i se faʻaopoopoga tutusa o tupe maua mo miners mumu.
This disequilibrium leaves green miners earning more revenue per block/hash than red miners. This is, incentivize wise, obviously unsustainable. One of two things will happen over time: 1) either the green miners will reinvest the extra revenue they are acquiring and expand their percentage of the hashrate, or 2) miners will defect from the red side and the green set of miners will grow in percentage of the hashrate that way.
O lenei malosi o le maualuga o totogifuapauina mo miners lanu meamata o le a mafua ai le tuputupu ae o le hashrate o miners lanu meamata, e tusa lava pe ala i le toe teu faafaigaluegaina po o le defection mai miners mumu, seia oo atu i se paleni lea o le verboten transactions 'blockspace manaoga tulaga ese ma feuiaiga masani, ma o vaega uma e lua o tagata maina o loʻo maua pe tusa o le tutusa tupe maua. O lenei paleni o le a tumau seia oo ina sili atu le manaoga o fefaʻatauaiga verboten mo blockspace e sili atu i lo latou avanoa, ona maua ai lea e le siva atoa o miners lanu meamata seʻia oʻo ina latou tuputupu aʻe i sea faʻasoa fesoʻotaʻiga i se tulaga paleni o tupe maua tutusa.
This dynamic is why Bitcoin is censorship resistant. Not because all miners are not capable of censoring something, but because miners are incentivized to include something other miners are censoring through market dynamics. If some miners censor a class of transactions, they decrease the amount of blockspace available to them and drive up the fees they are willing to pay. Pure and simple. Unless miners are completely irrational, in which case Bitcoin’s entire security model is called into question, some will include these transactions and earn the extra revenue.
