Which exchange should be used?

Of all the exchanges mentioned in Discord, Telegram, Slack and Twitter, none seems to stand out as the obvious choice. All seems to have had their good share of shenanigans, on way or another. Either by delisting, which is an obvious no go, or more dangerous business models like hyperleveraging, crypto loans and worse.

Which will be the first BSV application that will catch mainstream adoption?

Now, this will obviously require some speculation, but why not. There are many exciting Bitcoin SV applications being released practically at a daily basis, but they are arguably mostly used by the (still small in grand scheme of things) BSV community.

I predict that at some point we’ll see one/some of those applications gain attention of the general public and take off - probably dragging the entire ecosystem with them.

If you could bet which (or what kind of) app that will be, what would you bet on?

If transaction hashes only are stored in blocks, then where is OP_RETURN data stored?

An answer to a previous question and the whitepaper both agree that blocks don’t store full transactions, but rather, transaction hashes.

So then, what if I add data in OP_RETURN, say, the text “Hello, world!” Isn’t that a transaction output, or at least contained in an output, and therefore part of a transaction?

If not, or if so and only transaction hashes, not transactions themselves persist, then how does the OP_RETURN data stay on the blockchain?

Double hash in Bitcoin

what exactly is this? Does this mean every TX gets hashed twice? How does it help to filter the content from the block chain (As Dr. Wright said)? Why cant i hash it just once and save the hash of the TX and prune the data (illegal)? Isnt the content now filtered with just a single hash? or am i getting it wrong?
