becomes necessary, although I've done everything I can to build in
extensibility and versioning.
No one knows because Satoshi Nakamoto is an anonymous Contributor as Bitcoin chose to remain anonymous, only that what he has attempted is another way to build a decentralized money and fund system without a central unit. No one knows @Vampobit.
