Nano has one blockchain for each account which is controlled by the account's private key, and each blockchain is replicated to all peers in the network. We call this arrangement a block lattice.
Balances are transferred between blockchains through send and receive blocks. Send blocks reduce the balance of an account and marks the delta as receivable by an account number. At a later time, the receiving account creates a receive block, which increases the balance of their account by the delta.
Distributed agreements like Proof-of-Work or Proof-of-Stake are unnecessary, since the account owner has authoritative control over transactions.
@Luandro If the battery charger fails, I'd try charging it with a car and jumper leads, like you're jump starting another car. Starting the car on its own battery and then connecting the dud battery and watching a voltmeter to see if it's charging. That should produce a high enough current to dislodge any solid lead sulfate crystals that form after excessive discharge and inadequate charge current from the solar to break down the crystals. Some crystals will likely drop to the bottom of the battery exposing fresh lead and lose you some capacity if the battery recovers. Deep cycle batteries contain more lead to allow you to "deep" cycle them sometimes. You just have to be careful that one of the cells isn't shorted causing the battery to heat up and boil the electrolyte if it's a wet cell. If the electrolyte level gets lower than the plates, arcs can form at the shorted cell that ignites the hydrogen sulphide gas formed during charging. Most sealed batteries have a vent that will burst should excessive gas be formed.
From my reading of the scientific literature, desulfation chargers only work on some lead acid battery chemistries, dictated by the materials used in the anode and cathode and should be a last resort as they often damage some chemistries further.
@andrestaltz Excellent! I'm just glad I could point you in the right direction, and the smile is thanks enough. :)
