/**
|
|
* Returns a synopsis of the blockchain used for syncing. This consists of a list of
|
|
* block hashes at intervals exponentially increasing towards the genesis block.
|
|
* When syncing to a peer, the peer uses this data to determine if we're on the same
|
|
* fork as they are, and if not, what blocks they need to send us to get us on their
|
|
* fork.
|
|
*
|
|
* In the over-simplified case, this is a straighforward synopsis of our current
|
|
* preferred blockchain; when we first connect up to a peer, this is what we will be sending.
|
|
* It looks like this:
|
|
* If the blockchain is empty, it will return the empty list.
|
|
* If the blockchain has one block, it will return a list containing just that block.
|
|
* If it contains more than one block:
|
|
* the first element in the list will be the hash of the highest numbered block that
|
|
* we cannot undo
|
|
* the second element will be the hash of an item at the half way point in the undoable
|
|
* segment of the blockchain
|
|
* the third will be ~3/4 of the way through the undoable segment of the block chain
|
|
* the fourth will be at ~7/8...
|
|
* &c.
|
|
* the last item in the list will be the hash of the most recent block on our preferred chain
|
|
* so if the blockchain had 26 blocks labeled a - z, the synopsis would be:
|
|
* a n u x z
|
|
* the idea being that by sending a small (<30) number of block ids, we can summarize a huge
|
|
* blockchain. The block ids are more dense near the end of the chain where because we are
|
|
* more likely to be almost in sync when we first connect, and forks are likely to be short.
|
|
* If the peer we're syncing with in our example is on a fork that started at block 'v',
|
|
* then they will reply to our synopsis with a list of all blocks starting from block 'u',
|
|
* the last block they know that we had in common.
|
|
*
|
|
* In the real code, there are several complications.
|
|
*
|
|
* First, as an optimization, we don't usually send a synopsis of the entire blockchain, we
|
|
* send a synopsis of only the segment of the blockchain that we have undo data for. If their
|
|
* fork doesn't build off of something in our undo history, we would be unable to switch, so there's
|
|
* no reason to fetch the blocks.
|
|
*
|
|
* Second, when a peer replies to our initial synopsis and gives us a list of the blocks they think
|
|
* we are missing, they only send a chunk of a few thousand blocks at once. After we get those
|
|
* block ids, we need to request more blocks by sending another synopsis (we can't just say "send me
|
|
* the next 2000 ids" because they may have switched forks themselves and they don't track what
|
|
* they've sent us). For faster performance, we want to get a fairly long list of block ids first,
|
|
* then start downloading the blocks.
|
|
* The peer doesn't handle these follow-up block id requests any different from the initial request;
|
|
* it treats the synopsis we send as our blockchain and bases its response entirely off that. So to
|
|
* get the response we want (the next chunk of block ids following the last one they sent us, or,
|
|
* failing that, the shortest fork off of the last list of block ids they sent), we need to construct
|
|
* a synopsis as if our blockchain was made up of:
|
|
* 1. the blocks in our block chain up to the fork point (if there is a fork) or the head block (if no fork)
|
|
* 2. the blocks we've already pushed from their fork (if there's a fork)
|
|
* 3. the block ids they've previously sent us
|
|
* Segment 3 is handled in the p2p code, it just tells us the number of blocks it has (in
|
|
* number_of_blocks_after_reference_point) so we can leave space in the synopsis for them.
|
|
* We're responsible for constructing the synopsis of Segments 1 and 2 from our active blockchain and
|
|
* fork database. The reference_point parameter is the last block from that peer that has been
|
|
* successfully pushed to the blockchain, so that tells us whether the peer is on a fork or on
|
|
* the main chain.
