Thanks for this breakdown. I think y

Are you proposing a soft fork to include the number of transactions in a
block in the block headers to compensate for the broken Merkle format? That
sounds like a good idea.

It's well known that the Bitcoin merkle tree algorithm fails to distinguish
between inner nodes and 64 byte transactions, as both txs and inner nodes are
hashed the same way. This potentially poses a problem for tx inclusion proofs,
as a miner could (with ~60 bits of brute forcing) create a transac
Hi Thomas,
Thanks for considering this suggestion. You've raised some interesting
points (and concluded that it could be very difficult to implement). I'm
not yet at a point where I could answer any questions about implementation
details with any authority. With that caveat, your points are wor
eMMC storage, which low end devices often use, come in 2x increments. Running a
pruned full node on 8 GB is difficult if not impossible (the UTXO set peaked at
3.5 GB in January, but a full node stores additional stuff).
However, 16 GB is only €10 more expensive and presumably standard by the ti
What you're saying makes sense.
By the way, an even stronger reason why you shouldn't be able to
"repurpose" just a Graftroot signature as a transaction: You may want
to reveal to others that you've delegated. But if an observer sees the
delegation (literally the Graftroot signature), this observe
