Who will reach speed of light first?

Whenever the fastest antelopes escape and the slowest are eaten, it becomes more and more difficult for future lions to catch the fast antelopes, so that only the fastest lions can survive and reproduce. This leads to ever faster lions and antelopes. So the question is, who will reach the speed of light first? Lion or antelope?

Christians - which wife with me in Heaven?

Asking for a friend…….

In Christianity, suppose my wife passes away.
We had always considered ourselves “soul mates” who would be reunited in heaven.

I meet someone else, fall in love, and marry wife number 2. My love for number 2 seems to be just as strong as wife number 1…..I consider her also to be my soul mate?

How is this resolved in Christian heaven? Who will I spend eternity with?


Is it possible to use browser's crpyo primitives with bsv library?

I have some code that does a lot of HD derivation and ECIES encryption/decryption and I noticed that it runs quite slow in the browser. I did some profiling and it seems that it spends most of the time in the libraries that handle primitives (sha256 hashing, big int, …).

This makes sense as it seems that we have this primitives natively in node, but we need to use libraries in the browser. I did some Googling and it seems that newer browsers do have some support for this things so I was wondering if it is possible to use that when available? I suspect that would speed up things significantly?

I am thinking about browser’s native APIs such as SubtleCrypto and BigInt. Or even an Emscripten-compiler Javascript library such as js-nacl.

Which transactions are available from "getrawtransaction" RPC call when "-txindex" is disabled?

I noticed that even with -txindex disabled getrawtransaction RPC call still returns transactions. I assume that without the full index it will still return transactions that node software needs for other reasons (wallet transactions, UTXOs, …). But what are those cases? Which types of transactions are available even without the full transaction index? And what happens if I request a transaction that is not available?


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?

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.

How does IP2IP work?

I heard a lot of discussions mentioning IP2IP at the recent CoinGeek conference in Seoul. I really like the idea of users exchanging transactions peer-to-peer, but I am wondering how IP2IP works on a technical level?

Does it require a daemon/service running on the recipient’s computer that listens for incoming transactions or is there some other approach?


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?

I would also like to, assuming I am looking at a block’s HEX blob, be able to decode it/determine various parts of it.
