Lightning Bitcoin (LBTC)LBTC
A December 2017 fork at block 499,999 that replaced proof of work with delegated proof of stake, unrelated to the Lightning Network despite the name.
The wiki's angle: LBTC is a naming hazard. It borrowed the word “Lightning” from Bitcoin's payment-channel network while changing Bitcoin's consensus to delegated proof of stake. It has no stated connection to the Lightning Network found in its README or ANN thread.[1][2]
Design
The README says Lightning Bitcoin is forked from Bitcoin Core and that its full node “replaces PoW consensus of Bitcoin with DPoS”, adding replay protection and register, vote and cancel-vote transactions[1]. The README says holders vote on improvement proposals and on the delegates who maintain the network as “Lightning Nodes”[1]. The ANN thread describes 2 MB blocks[2].
Fork and launch
The ANN thread says Bitcoin holders could claim LBTC 1:1 if they held BTC at block 499,999 on 18 December 2017[2]. That block's header time is 18:34:47 UTC on 18 December 2017[3]. The project's own timeline lists the fork on 18 December 2017 and the mainnet launch on 4 February 2018[4].
Inactive coins
The ANN thread says there was no premine, but that coins belonging to addresses inactive since 31 January 2013 were taken for “ecological construction” and managed by the LBTC foundation, with an offer to return them on request[2]. The project's timeline says a governance vote in September 2018 approved removing pre-fork data, followed by a remapping in October 2018[4]. Whether the chain still runs is unknown in this wiki[4].
