I found strange BTS7wzHgbPEHouxuvM16rDGNo4d9CdYYLajS16y3uawoptKrKNXHE key in stack which doesn't have any relationship with my account. I checked the transaction.cpp code and seems it's a public key recovered from signature. Does it have relation with how the public key is recovered?

Nodes must remember all unexpired transactions to prevent replay attacks. Increasing the allowed expiration time means higher resource usage on all nodes.

There is another reason too: The TaPOS parameters make use of a truncated block number which is so short that it only covers about 2.4 days of blocks.

What if tx.ref_block_prefix does not match ref_block_num? Will the tx be rejected or it's just a ref. as name implies?

Why not just make GRAPHENE_DEFAULT_MAX_TIME_UNTIL_EXPIRATION long enough like the same 4 weeks as proposal max time until expiration?

I'm working on a multi-sig related function and found it too limited for transaction expiration.
I checked the code and found GRAPHENE_DEFAULT_MAX_TIME_UNTIL_EXPIRATION is set to 1 day. This is way too short for me as the two parties in multi-sig need more than 1 day to cooperate on transaction signature.
How can I bypass this limitation?

Thanks for the info. It explains why the chain stops at 18,154,987.
Do you have more information (links) on the issue?

我觉得这个项目可以推广了。有没有推广激励呢？

暂时还没有很好的推广思路，正在头痛呢。
有没有什么建议？
