Largest Bitcoin block is won with NFT and new developer war can begin

Bitcoin Blocks

A block of Bitcoin with nearly 4 MB (3,955,272 bytes) was mined this Wednesday (1st), making it the largest in history to date. Despite its record size, the block of 774,628 had only 63 transactions.

One of these transactions broke another record and was responsible for occupying 99% of the entire block. With a weight of 3,938 MB, such a transaction is an NFT and is already leading to heated discussions about the real benefits of this technique.

Transaction is an NFT

To the surprise of many, such a transaction is an NFT. These are called Ordinals and take advantage of the Taproot upgrade to put more data on the Bitcoin blockchain at a low price.

One such technique was explained by Casey Rodarmor a few weeks ago. However, even famous Bitcoin developers have already expressed their discomfort with the project.

“We put it in the witness, which is usually reserved for transaction signatures”Rodarmor explained. “Witness data is also cheap, because it gets the segwit (separated witness) discount, so witness bytes count for 1/4 the value of other parts of a transaction.”

“Is someone already working on a spam filter for this mess? #bitcoin”replied Bitcoin developer Luke Dashjr.

Another user noticed that “the spam filter is the transaction cost”but the answer did not sit well with Dashjr, saying so “a spam filter that doesn’t filter spam is a failure.”

More importantly, Luke Dashjr’s complaint turned into yet another NFT on the network, showing off the whole community’s sense of humor.

To make all the irony complete, Dashjr himself has already been criticized for inserting several biblical messages into Bitcoin blocks in 2011.

New war between developers?

Since its inception, the community has defined Bitcoin blocks as 1MB in size. With the arrival of segwit, they now have 2 MB of storage space on the nodes.

However, some believed that this was not enough to handle network transactions, suggesting that in addition to segwit, the block size should also be doubled. After years of debate, the so-called “block size war” gave birth to Bitcoin Cash (BCH), BTC’s most famous clone.

More recently, the advent of Taproot has expanded these limits to 4 MB, in addition to using other techniques. Despite not having as much adoption as Segwit, the arrival of NFTs in Bitcoin is already troubling many people.

After all, the main problem is that an NFT on Bitcoin can take up the space of hundreds of regular transactions, which end up in the queue and therefore increase costs for everyone.

Therefore, we can expect another war between developers to arise. As seen above, one of the most respected names is already suffering from the situation, which should quickly get worse as word spreads.
