Abstract: A proposal for an implementation of blockchain, inspired by Satoshi Nakamoto, that may be useful during a post-apocalyptic period when electricity is unavailable.

If we make the assumption that an event has occurred (massive and recurrent EMP type events) that makes the generation and general availability of electricity impossible, then what is to be done to maintain an immutable, permissionless ledger of transactions. (We will not delve into post-apocalyptic requirements or applications, as this is deemed to be outside the scope of this paper)

Transactional data

Consider a village or marketplace, where stall or shop owners and transacting with people. For each transaction an invoice is created, capturing the pertinent information on a standard sized piece of paper or cardboard. This invoice is then sent, by runner, to the Bingo Tent (BT), where a team of Bingo Blockchain Transcribers (BBT) service incoming invoices, creating 50 copies of each invoice.

The Bingo Tent

Inside the Bingo Tent (BT) are 50 Bingo Blockchain Workers (BBW). Their job is to play Bingo (day in, and day out). 3 shifts of BBW ensure the Blockchain is always available and able to store transactions.

BBW and BBT as remunerated for their efforts by an endless supply of beverages, pizza and doughnuts (Bingo Blockchain Refreshments).

Each BBW sits at a desk, playing Bingo. As transactions complete transcription, runners go into the BT and place one transcript of the transaction invoice on each desk of the 50 BBW staff.

At the front of the BT is the Bingo Cantor (BC), who selects random numbers (RN) from the Bingo Roller Cage (BRC).

Upon selection, the BC shouts out the selected RN, and the BBW inspect their Bingo Matrix Card (BMC), and if the RN is indicated, mark it.

The Rules of the Blockchain

The first number shouted by the BC at the start of each round is not selected from the RN, but is the last number shouted in the previous round. Each player fills this in on the Free Space cell on the BMC.

Each BBW is compelled to play by the rules. Mark only the numbers that are shouted by the BC. If any BBW marks down a number that was not called, the offending BBW will be excluded from the Bingo round in question, and may be regarded with suspicion in future rounds.

Winning the Round

When a BBW has marked all the spaces other than the Free Space (FS), the BBW must immediately jump to their feet and shout “BINGO!!”. This marks the end of that particular round of Bingo. The winning BBW is rewarded with an extra slice of pizza and a coffee.

At this point the BBW places the completed BMC on top of the pile of transaction invoices that have accumulated on his/her desk to mark the winning point. The BBW must then proceed to the front of the BT and place the pile of transaction invoices and BMC into the provided Invoice Hopper (IH).

Other BBW must at this stage dispose of all transaction invoices on their desks in the provided garbage bins.

The Resultant Bingo Blockchain

Transactions are stored, inside the IH, in “blocks”, with the BMC acting as an informational header. The number written in the Free Space cell must be written on the preceding block’s header card, thus linking the blocks together in a “chain of blocks”.

Immutability

The security of the Bingo Blockchain, and its resistance to tampering, is ensured by the last and most important rule of Bingo Blockchain.

All IH are stored in a secure corner of the BT, and are guarded by the BBW and BBT. If any tampering is detected, the supply of BBR will be curtailed.

Conclusion

By this method of Proof of Bingo (PoB) it is possible for a post-apocalyptic society to continue to enjoy the enormous societal benefits of the Blockchain.
