What altchains if any fixed txn maleability?

Nxt.

IIRC, it was just a tweak needed to ensure safety (Jean Luc says he has 4 bolts on his door, not just two  ). I think CfB thought Nxt was safe without any changes but don't quote me.

We have similar interests if the goal is to make a viable interblock chain trade system.

I am exploring the possibility of using the Lighting Networks approach for a real time inter blockchain trade system, which requires a malleability fix in Bitcoin.

The first coin to fix this was Cryptonite XCN - https://bitcointalk.org/index.php?topic=713538.0

from their wiki page:

Removing Transaction Malleability

One of the reasons Cryptonite does not suffer from transaction malleability is because it doesn't use scripting, but more importantly it doesn't include the signatures when hashing a transaction because signing the same data with the same key produces different signatures each time. The sender will sign the txid, but signing it many times in no way alters the txid, only the signatures. Thus attempting to alter the contents of the transaction will always change the txid and as a result invalidate the signature(s).

That was just me spit balling about a future feature (Smart Contracts)   I think they have something simpler in mind.


NxtAT (Nat Automated Transactions) aims for Atomic Cross Chain Transactions. The Nxt core devs weren't convinced it was safe so it has been implemented in Burst (a Nxt clone with HDD mining). Qora is also implementing it so they should be able to demonstrate the tech soon (AT is intended to be blockchain agnostic, CIYAM is the dev). If it is safe and all is well, Nxt may integrate it into the core but it isn't guaranteed.

Another project is "FSM with assembly language", a similar thing cone by one of the devs from the AT project. This has been implemented in NFD (now HZ), which is another Nxt clone. That is on the testnet now IIRC.
