Block Size Debate Rehashed: Incentives to Run a Full Node ...

Bitcoin Full Node Incentives

Looking to do a research paper on Bitcoin Full Node historical numbers.
I only know of Bitnodes:
https://getaddr.bitnodes.io/
Also, looking for any data on previously attempted incentives and the results.
Thanks in advance everyone.

"network disruption as a service" and proof of local storage | Sergio Lerner | Mar 16 2015

Sergio Lerner on Mar 16 2015:
The problem of pseudo-nodes will come over and over. The cat and mouse
chase is just beginning.
It has been discussed some times that the easiest solution world be to
request some kind of resource consumption on each peer to be allowed to
connect to other peers.
Gmaxwell proposed Proof of Storage here:
https://bitcointalk.org/index.php?topic=310323.msg3332919#msg3332919
I proposed a (what I think) is better protocol for Proof of Storage that
I call "Proof of Local storage" here
https://bitslog.wordpress.com/2014/11/03/proof-of-local-blockchain-storage/
. It's better because it does not need the storage of additional data,
but more importantly, it allows you to prove full copy of the blockchain
is being maintained by the peer.
This is specially important now that Bitnodes is trying a full-node
incentive program that may be easily cheated
(http://qntra.net/2015/02/pseudonode-proxy-fools-bitcoin-full-node-incentive-program/)
Proof of local storage allows a node to prove another peer that he is
storing a LOCAL copy of a PUBLIC file, such as the blockchain. So the
peer need not waste more resources (well, just some resources to
encode/decode the block-chain).
The main idea is to use what I called asymmetric-time-encoding.
Basically you encode the block-chain in a way that it takes 100 more
times to write it than to read it. Since the block-chain is an
append-only (write-only) file, this fit good for our needs. For instance
(and as a simplification), choosing a global 1024-bit prime, then
splitting the block-chain in 1024-bit blocks, and encrypting each block
using Polihg-Hellman (modexp) with decryption exponent 3. Then
encryption is at least 100 times slower than decryption. Before PH
encryption each node must xor each block with a pseudo-random mask
derived from the public IP and the block index. So block encryption
could be:
BlockEncryptIndex(i) = E(IP+i,block(i))inv(3) (mod p),
where inv(3) is 3-1 mod (p-1). E() could be a fast tweaked encryption
routine (tweak = index), but we only need the PRNG properties of E() and
that E() does share algebraic properties with P.H..
Two protocols can be performed to prove local possession:
  1. (prover and verifier pay a small cost) The verifier sends a seed to
derive some n random indexes, and the prover must respond with the hash
of the decrypted blocks within a certain time bound. Suppose that
decryption of n blocks take 100 msec (+-100 msec of network jitter).
Then an attacker must have a computer 50 faster to be able to
consistently cheat. The last 50 blocks should not be part of the list to
allow nodes to catch-up and encrypt the blocks in background.
  1. (prover pay a high cost, verified pays negligible cost). The verifier
chooses a seed n, and then pre-computes the encrypted blocks derived
from the seed using the prover's IP. Then the verifier sends the seed,
and the prover must respond with the hash of the encrypted blocks within
a certain time bound. The proved does not require to do any PH
decryption, just take the encrypted blocks for indexes derived from the
seed, hash them and send the hash back to the verifier. The verifier
validates the time bound and the hash.
Both protocols can me made available by the client, under different
states. For instance, new nodes are only allowed to request protocol 2
(and so they get an initial assurance their are connecting to
full-nodes). After a first-time mutual authentication, they are allowed
to periodically perform protocol 1. Also new nodes may be allowed to
perform protocol 1 with a small index set, and increase the index set
over time, to get higher confidence.
The important difference between this protocol and classical remote
software attestation protocols, is that the time gap between a good peer
and a malicious peer can be made arbitrarily high, picking a larger p.
Maybe there is even another crypto primitive which is more asymmetric
than exponent 3 decryption (the LUC or NTRU cryptosystem?).
In GMaxwell proposal each peer builds a table for each other peer. In my
proposal, each peer builds a single table (the encrypted blockchain), so
it could be still possible to establish a thousands of connections to
the network from a single peer. Nevertheless, the attacker's IP will be
easily detected (he cannot hide under a thousands different IPs). It's
also possible to restrict the challenge-response to a portion of the
block-chain, the portion offset being derived from the hash of both IP
addresses and one random numbers provided by each peer. Suppose each
connection has a C-R space equivalent to 1% of the block-chain. Then
having 100 connections and responding to C-R on each connection means
storing approximate 1 copy of the block-chain (there may be overlaps,
which would need to be stored twice) , while having 1K connections would
require storing 10 copies of the blockchain.
Best regards,
Sergio

The lack of incentives to run a full node: the great weakness of Bitcoin?

I am a strong believer in the original vision of Satoshi. I want to run a full node, but to be honest, it's a hassle to set up and its expensive to maintain. Most people don't have super fast internet connections or tons of RAM and hard disk space just lying around unused. As a matter of fact, most people will not run a full node unless there is an incentive to do so.
Incentives is the reason miners can make a lot of noise but will always follow consensus (because incentives become punishments at the same time). I do not see this same mechanism being applied to running full nodes. We are relying essentially on the good will of some people, and of the paranoia of many others who want to make sure they can verify transactions.
If we want to increase the number of nodes, we either have to 1. create incentives 2. completely eliminate barriers of entry to create one 3. combine the two
I really want to hear people's opinions on this topic. I have yet to hear a clear path towards a solution, or how this is blown out of proportion (like the whole 51% attack vector)

Full node incentives and 21.co: return to a decentralised Bitcoin network

It looks like it would be pretty easy to make a Bitcoin node that pays for itself by collecting fees from those requesting services. If this is the case, then full nodes could be subsidised by the ecosystem. This would pay for the bandwidth, storage, and other infrastructure needs required to run nodes, encouraging a return to a decentralised network. This could also absorb the increasing overhead of larger blocks.
Let's talk about this.

A better question to ask is "do we actually need tons of full nodes like some people claim?"
Imagine you wanted to change the incentive structure of bitcoin to divert some of the block reward to full nodes. There is actually no way to do this because one full node is sufficient to spoof 10,000 or 100,000 full nodes. Any sort of validation you require of a single full node to prove it is a full node (to get rewarded) can be passed along to the 10,000 or 100,000 fake nodes.
What this tells you is that, economically, the value of one full node is approximately equal to the value of 100,000 full nodes.
Part of why people have gotten confused and gone down a silly (blockstream) path on this question is because the original white paper by Satoshi talks about the importance of nodes, but there was no concept of a non-mining full node. It was the act of mining that provided the security, not the node part. The bitcoin community has suffered mightily under the weight of some people's delusions that we need tens of thousands of non-mining full nodes. There is absolutely no reason for such a thing.

It is a design flaw that I have no incentive to contribute what little computing power I have to mining; running a Tor node contributes significantly to the Tor network, but running a full Bitcoin node does very little. I think Satoshi would be dismayed by the centralization of mining power.

No, fuck you!
