this can be "fooled" too

if just adding a date..
the true owner of the 2009 address can at any time..
create a new chain. and put an epoch time in a sig of 1291513567 (dec 2009) and then just hash a block with low difficulty and reference that hash in a next signature message where by they pretend to have transferred it every 6 months for 13 years they can easily reference a previous hash of 26 taints previous hashes and pretend each are done 6 months apart by just adding 15778463 to the epoch time each time they sign.. even though reality is they done 26 signatures in one day

and boom. this new chain has a better provenance than this topics sigchain is pretending to have provenance of

thus making the sigchain proposed no longer valid

Then he would have a 'signature chain' fork like a Bitcoin fork. Our rules wouldn't accept their transactions.

And that example above is the initial signature and doesn't need a transaction as mentioned in the 'how it works' https://bitcointalk.org/index.php?topic=5425241.msg61386368#msg61386368

Here is a regular 'signature chain':

created a 'signature chain' transfer:

1NCLNyKPGjx2GwdRSPB5xqfy58WtGtgNgo is the starting address (first time used in 2022, it is not an old address, just to show that it works)

The owner/holder of 1NCLNyKPGjx2GwdRSPB5xqfy58WtGtgNgo transfers the 'signature chain' to 1M4wDv1tGEt2yPL6FrkM6o19jxV6mdopnP:

1) signs a message (message is the Bitcoin address of the new owner)

and can transfer it.

It works

You can't break it. It works.
