Review Tornado Cash Proposal 65

Proposal #65: Update ETH RPC List and ENS

Reason: The current ETH RPC List on the UI no longer support historical queries, necessitating an update to the default ETH RPC list.

UI Update Details:

ETH RPCs:  blockscoutRPC,blastRPC,xrpc, gasHawkRPC, lavaRPC,torndaoRPC,sentioRPC,tornadoRPC

Target: Update the IPFS hash for the Tornado Cash classic UI associated with the ENS domain tornadocash.eth.
        
UI Code Repository: https://codeberg.org/torndao/classic-ui/commits/branch/development
        
UI Code commit: https://codeberg.org/torndao/classic-ui/commit/d52c01688f5697e60a1d3c598a4c30989403fb0f
        
IPFS Hash: bafybeie5hxovqc4ifcnrnhvmjbefxgeix6oqvzaspyytdxiyscji22v5pu (accessible via https://ipfs.io/ipfs/bafybeie5hxovqc4ifcnrnhvmjbefxgeix6oqvzaspyytdxiyscji22v5pu)
        
IPFS Hash Verification Tool: https://codeberg.org/torndao/tornado-ipfs-ui
        
Content Hash: e301017012209d3ddd580b88289b169eac48485b9888bf9d0ae4127e3131dd1890928d6abd7d (calculated using the tool at https://codeberg.org/torndao/tornado-ipfs-ui/src/branch/main/ContentHash.html)
       
Affected DomainsThe updated IPFS hash will affect the following domains:
tornadocash.eth.limo
tornadocash.eth.link
ipfs.io/ipns/tornadocash.eth
tornadocash-eth.ipns.dweb.link

This proposal passed with 330.32k TORN (72%) voting For and 125.59k TORN (28%) voting Against. The required quorum of 100k TORN was met, and the proposal was successfully executed here (Feb-14-2026 12:20:23 PM UTC).

Analysis

Relevant Links

There are three new commits compared to the last version (https://tornadocash.eth.limo/governance/63; https://codeberg.org/torndao/classic-ui/commit/30c4b44a5cd96811e17ef46d921ea8e1841a05d0; https://ipfs.io/ipfs/bafybeiadcezfjx4ewel2xbdic66a4oj5ei6wtrvcbnirao5543cqtckukm):

Commit Analysis

  • Commit 6ed828199d8a9eb4fedec2764712af81bd13a7e5 (commit message: "Update the @tornado library file URL.") is the most dangerous one since it changes the npm registry link to @tornado:registry=https://codeberg.org/api/packages/torndao/npm/ (see https://codeberg.org/torndao/-/packages) and also updates the yarn.lock file.

Let's look at the diffs of the different packages.

=> The diff looks safe because the changes are purely compiler-output and metadata updates, with no runtime or behavioural modifications. I excluded the .d.ts files from the comparison because they are compile-time type artifacts and cannot introduce runtime behaviour or supply-chain payloads.

IPFS Hash Verification

First, we verify that the claimed commit hash bafybeie5hxovqc4ifcnrnhvmjbefxgeix6oqvzaspyytdxiyscji22v5pu is correctly calculated. I use https://codeberg.org/torndao/tornado-ipfs-ui - the original version seemed fine to me until now & the latest commit is just the commit hash update: https://codeberg.org/torndao/tornado-ipfs-ui/commit/982f9f4efbe65e756dd5e3a47069613457558bc2.

~$ git clone https://codeberg.org/torndao/tornado-ipfs-ui.git
~$ docker build -t tornado-classic-ui .
~$ docker container run --rm -it --entrypoint cat tornado-classic-ui /app/ipfs_hash.txt

which returns bafybeie5hxovqc4ifcnrnhvmjbefxgeix6oqvzaspyytdxiyscji22v5pu. So the claimed IPFS hash is correctly derived.

Let's use on-chain data to verify this as well. Let's get the ENS public resolver (0x00000000000C2E074eC69A0dFb2997BA6C7d2e1e is the ENS registry):

cast call 0x00000000000C2E074eC69A0dFb2997BA6C7d2e1e "resolver(bytes32)(address)" $(cast namehash tornadocash.eth) -r https://eth.drpc.org

which returns 0x4976fb03C32e5B8cfe2b6cCB31c09Ba78EBaBa41.

Now we can get the IPFS hash (sorry some custom Bash magic lol):

cast call 0x4976fb03C32e5B8cfe2b6cCB31c09Ba78EBaBa41 "contenthash(bytes32)(bytes)" $(cast namehash tornadocash.eth) -r https://eth.drpc.org | sed 's/^0xe301//' | xxd -r -p | base32 | tr -d '=' | tr '[:upper:]' '[:lower:]' | sed 's/^a/ipfs:\/\/ba/'

which returns ipfs://bafybeie5hxovqc4ifcnrnhvmjbefxgeix6oqvzaspyytdxiyscji22v5pu. Looks good!

Finally, let's cross-check with with the eth.limo headers (since we don't trust anyone):

curl -sI https://tornadocash.eth.limo/ | grep -i "x-ipfs"

which returns

access-control-expose-headers: Content-Length,Content-Range,X-Chunked-Output,X-Ipfs-Path,X-Ipfs-Roots,X-Stream-Output
x-ipfs-path: /ipfs/bafybeie5hxovqc4ifcnrnhvmjbefxgeix6oqvzaspyytdxiyscji22v5pu/
x-ipfs-roots: bafybeie5hxovqc4ifcnrnhvmjbefxgeix6oqvzaspyytdxiyscji22v5pu

So we're good here.

Thanks for the detailed verification on the yarn.lock integrity checks. Fair point on the RPC too, agree.
