I'm not all the way through all of the docs yet, but had a few questions/comments: - The top-level doc ( https://github.com/Roasbeef/bips/blob/bip-taro/bip-taro.mediawiki) talks about embedding overlay metadata in the taproot script tree. From my reading, it seems like what gets committed is the root of the taro MS-SMT tree, while leaves of the tree itself are off-chain in a proof file. If that's the case, did you look at other mechanisms to commit to a merkle root? For example, I believe mainstay[1] uses a pay-to-contract/bip175[2]-like scheme to commit sidechain merkle roots to p2pkh/p2sh addresses with signature tweaks. Are there other interesting (to taro) spend-paths that need to be allowed that led to the taproot script tree being particularly helpful? - It appears that the transfer proofs are kept off-chain in another file which is passed between users, where the receiver can validate the transfer according to whatever semantics the taro-vm has at that moment and refuse to credit the sender if the transfer breaks some business logic or validation rules. This reminds me a lot of single-use-seals[3]. Is that the right way to think about what's going on here? If it is, then it looks like a Universe/Multiverse is an offload/aggregation mechanism that can keep track of asset lineages on behalf of users, which would be useful for light clients of heavily-used asset types (so your mobile client doesnt have to traverse the transfer lineage of some high-liquidity stablecoin or something). - Rubin made a good point above about how something like a conditional transfer in a taro asset won't necessarily cause the conditional bitcoin transfer to fail. My first thought was to have the "carrier utxo" for a taro asset be really small, like dust + some buffer. The thought being that I'm basically just paying gas and if I lose `dust+buffer` amount of bitcoin but not a lot of some token, then that's not great but not terrible. Where it gets bad is if the value of the taro asset that you're trying to transfer is close to or less than the value of the bitcoin that's being used to do the transfer. - There's been a lot of talk lately on the bitcoin-dev list about covenants, and I wonder if some of those designs (specifically TLUV or CTV) might be useful with Taro, to "lift" some of the taro conditions into covenants that encumber the underlying bitcoin. I don't have a design or anything, wondering if you've given this any thought. - was this originally named CMYK?

Hey Laolu,

Really interesting protocol.= I'm not all the way through all of the docs yet, but had a few questio= ns/comments:=C2=A0

The issue with a.) is that you're only ever fragmenting tokens,= so eventually you end up with lots of tiny but separate amounts.

Under this model, I suspect the fixed value token model (= e.g. 1, 2, 4, 8) might be preferable, as this prevents the entire supply fr= om getting split into tiny fragments.

The issue wi= th b.) is that you end up with a linked transaction graph, just like in Bit= coin. If you pick a random Bitcoin UTXO and try to trace it back to a coinb= ase, you'll quickly find that it could have come from many of them.

There's a third third smaller issue I want t= o point out, which is easily fixable and perhaps was just a typo.

What needs to be prevented here is that = a taproot tree contains more than one Taro tree, as that would enable the o= wner of the commitment to show different histories to different people.

Finally, let me conclude with two questions. Could yo= u clarify the=C2=A0purpose of the=C2=A0sparse merkle tree in your design? I= suppose you want to be able to open a commitment and show it contains a ce= rtain asset without having to reveal any of the other assets and simultaneo= usly guarantee that you haven't committed to the same asset twice (i.e.= the SMT guarantees each asset gets a specific location in the tree)? Or is= there another reason?

And the second question =E2= =80=93 when transferring Taro token ownership from one Bitcoin UTXO to anot= her, do you generate a new UTXO for the recipient or do you support the abi= lity to "teleport" the tokens to an existing UTXO like how RGB do= es it? If the latter, have you given consideration to timing issues that mi= ght occur when someone sends tokens to an existing UTXO that simultaneously= happens to get spent by the owner?

In any case, I= =C2=A0hope this email was useful. Feel free to reach out if I can clarify a= nything.

Good luck with the protocol.

Hi y'al= l,

I'm excited to publicly publish a new protocol I've been= working on over the
past few months: Taro. Taro is a Taproot Asset Repr= esentation Overlay which
allows the issuance of normal and also collecti= ble assets on the main Bitcoin
chain. Taro uses the Taproot script tree = to commit extra asset structured meta
data based on a hybrid merkle tree= I call a Merkle Sum Sparse Merkle Tree or
MS-SMT. An MS-SMT combined th= e properties of a merkle sum tree, with a sparse
merkle tree, enabling t= hings like easily verifiable asset supply proofs and
also efficient proo= fs of non existence (eg: you prove to me you're no longer
committing= to the 1-of-1 holographic beefzard card during our swap). Taro asset
tr= ansfers are then embedded in a virtual/overlay transaction graph which uses= a
chain of asset witnesses to provably track the transfer of assets acr= oss
taproot outputs. Taro also has a scripting system, which allows for<= br>programmatic unlocking/transfer of assets. In the first version, the scr= ipting
system is actually a recursive instance of the Bitcoin Script Tap= root VM,
meaning anything that can be expressed in the latest version of= Script can be
expressed in the Taro scripting system. Future versions o= f the scripting system
can introduce new functionality on the Taro layer= , like covenants or other
updates.

The Taro design also supports = integration with the Lightning Network (BOLTs) as
the scripting system c= an be used to emulate the existing HTLC structure, which
allows for mult= i-hop transfers of Taro assets. Rather than modify the internal
network,= the protocol proposes to instead only recognize "assets at the edges&= quot;,
which means that only the sender+receiver actually need to know a= bout and
validate the assets. This deployment route means that we don= 9;t need to build up
an entirely new network and liquidity for each asse= t. Instead, all asset
transfers will utilize the Bitcoin backbone of the= Lightning Network, which
means that the internal routers just see Bitco= in transfers as normal, and don't
even know about assets at the edge= s. As a result, increased demand for
transfers of these assets as the ed= ges (say like a USD stablecoin), which in
will turn generate increased d= emand of LN capacity, result in more transfers, and
also more routing re= venue for the Bitcoin backbone nodes.

The set of BIPs are a multi-pa= rt suite, with the following breakdown:
=C2=A0* The main Taro protocol: = https://github.com/Roasbeef/bips/blob/bip-taro/bip-tar= o.mediawiki
