Guardian
From the crucible of the Blocksize Wars, a Guardian arose, a steadfast defender of decentralization who knew the true cost of compromise. Between Block 420,000 and 709,631, they stood with the UASF and SegWit, choosing the arduous path of independent validation over blind trust in centralized power. Their unwavering commitment secured Bitcoin’s immutable future, forever cementing the ossified path against the tides of change.
