b) are bitcoin-qt 0.8 and bitcoin-xt 10.1 even remotely compatible?
I haven't yet installed XT, but as it says on their github, XT and Core are compatible.
OK... so I guess a corollary question would be:
b1) are bitcoin-qt 0.8 and bitcoin-qt 10.1 even remotely compatible?
I'm concerned with both the question of whether the *.blk file archival format has changed from 0.8 to 10.0 as well what the *.blk archival format is between qt and xt.
Same goes for wallet.dat.
Just read
https://bitcoin.org/en/release/v0.10.0, and now it looks like there are some blk file format differences that could send me in a tailspin. I'm not sure I buy the 3hrs to full sync. Took me 3 weeks to bring 0.8 back to sync, but if the torrent works, I'll just try that.
Thx.
