Thanks again to the NSF, Sun Microsystems, and the Andrew W. Mellon Foundation for the funding that allowed us to develop the system. Many thanks to the steadfast support of the libraries of the LOCKSS Alliance, and the libraries and publishers of the CLOCKSS Archive, that has sustained it in production. Special thanks to Don Waters for facilitating the program's evolution off grant funding, and to Margaret Kim for the original tortoise logo.Now for some more gratuitous self-promotion. This means:
- I started work on decentralized, permissionless peer-to-peer systems a quarter of a century ago.
- It is two decades since we were awarded an SOSP "Best Paper" for Preserving peer replicas by rate-limited sampled voting.
- Next month it will be a decade since my first post on cryptocurrencies, The Bitcoin vulnerability.
- It is five years since I posted Bitcoin's Academic Pedigree, based on the paper by Arvind Narayanan and Jeremy Clark, showing that all the techniques Satoshi Nakamoto assembled to create Bitcoin were published between 43 and 31 years ago now.
