On February 1, 2023, Bitcoin Community mined the biggest block in historical past, containing a virtually 4M largest transaction within the historical past, and the transaction charge is 0…
The massive transaction was despatched out by indie developer @udiWertheimer’s “Taproot Wizard”, an NFT undertaking on the Bitcoin community. The primary information is an NFT, not a hash, however a complete jpg picture.
The developer and undertaking haven’t been named, however the incident has triggered an enormous shock to the Bitcoin ecosystem, with Blockstream CEO Adam Again (@adam3us), Bitcoin Core developer @LukeDashjr and others calling it an assault on Bitcoin.
See CoinDesk’s report:https://www.coindesk.com/tech/2023/02/02/giant-bitcoin-taproot-wizard-nft-minted-in-collaboration-with-luxor-mining-pool/
Nonetheless, @udiWertheimer stresses that that is an innovation primarily based on “Ordinals” proposed by former Bitcoin core developer Casey Rodarmor.
Ordinals Doc:https://docs.ordinals.com/introduction.html
@udiWertheimer and Casey Rodarmor declare that the speculation can tag each primary unit of bitcoin: satoshi, and might be transferred. NFT is only one of some ways to allow extra performance on the Bitcoin community with out the necessity for a tough and mushy fork improve.
Rodarmor claims that Ordinals got here up as a result of Bitcoin lacks a steady public id. Bitcoin addresses are typically single-use, pockets accounts are native, and possession of private and non-private keys is just not transferable. So, by marking every satoshi in every output, Ordinals creates a transferable account or id for Bitcoin.

Particularly, within the NFT undertaking “Taproot Wizard”, the writer is meant to make use of a particular satoshi to consult with jpg pictures to implement the identification and circulation of the NFT. I haven’t absolutely understood how that is achieved.
It’s an attention-grabbing experiment in innovation, however bitcoin core doesn’t prefer it for a few causes:
-
Blockchain measurement inflation: This may consequence within the fast enlargement of bitcoin blockchain measurement, drastically elevated necessities for gadgets working full-node, ensuing within the discount of full-node of the entire community and the decline of anti-censorship. This was the principle motive for rejecting Vitalik’s sensible contract in OP_RETURN in 2014, and rejecting onerous fork enlargement in 2017.
-
Ecological affect: Massive transactions and Massive blocks exceeding expectations affect pockets, mining pool, browser and different ecological services, leading to some services irregular, such because the transaction of btc.com browser did not parse correctly.
-
Cut back safety: With a view to cut back the time of synchronization and verification of massive transactions and blocks, the mining pool or miners might select to not obtain and launch blocks with out verifying the transactions and blocks, which brings safety dangers.
Within the enlargement debate in 2017, Bitcoin core refused to develop via onerous fork to extend the block restrict, and selected to make use of segwit to carry the verification info exterior the block on the premise of avoiding onerous fork, in order to bypass the 1M block restrict and obtain partial enlargement. Nonetheless, there was no restriction on the size of the verification message. Onerous decisions now need to be made:
-
Do nothing and permit purposes to enter the Bitcoin blockchain on this approach, making the controversy about limiting OP_RETURN and increasing capability meaningless;
-
Onerous fork improve, write the scale restrict of the info witnessed in isolation into the consensus. That is additionally tough. The affect of onerous fork is nice and all nodes have to be up to date, which can be the principle motive for rejecting the New York Consensus improve to 2M in 2017.
-
Attain a partial consensus on main swimming pools and reject massive blocks and large tx. That is very unhealthy. It opens the door to guide block evaluate, loses the sense of decentralization, and is operationally tough for all swimming pools to adjust to.
Total, choice 1 is extra probably as a result of choice 3 is tough to attain, and the Bitcoin ecosystem is already very giant, making it tough to easily onerous fork.
