[Validator] Support ERC20 census proofs when the census origin is set as such

Currently, only Merkle proofs are supported.

ERC20 censuses need to have a special logic to take weight into account and check the given Ethereum Storage Proof.

data race

https://github.com/vocdoni/go-dvote/pull/16/checks?check_run_id=1573526167

Add tests for census handlers

Enhance tests to check combinations of different census types while using dump, importDump and publish.
Method to test:

bug: protobuf name conflict

Describe the bug
When executing the dvotenode, or the dvotecli, the logs show:

2021/03/04 10:51:14 WARNING: proto: file "common/vote.proto" has a name conflict over dvote.types.v1.UNKNOWN
A future release will panic on registration conflicts. See:
https://developers.google.com/protocol-buffers/docs/reference/go/faq#namespace-conflict

Current behavior
It shows this warning in the very first three lines of the logs

Expected behavior
This issue should be solved, or at least the warning removed from logs

System

OS: Manjaro
Software version: go version go1.16 linux/amd64
Commit hash 772dc69

feature: move from WebSockets to HTTPs client

Describe the feature
Use HTTP(s) as client protocol instead of WebSockets

Motivation

client/connection.go uses websockets as only way to create client communication, but in many scenarios (like the CLI) using HTTPs is preferable. Ideally, it should be able to choose between the two based on the protocol of the URI

feature: use server hostname as default Validator Name

Describe the feature
Use each validator's server hostname for the validator Name field

Motivation
This information will be nice to display on the explorer

Mesh subpub

Extend the current subpub package in order to achieve something like this: https://github.com/vocdoni/docs/wiki/SubPub-Mesh-routing

[Gateway/Oracle] Compute the scrutiny of Bridge processes, multiplying results by the weight

The current impementation adds +1 for every (valid) voted choice. However, this does not take weight into account.

On processes with an ERC20 census origin, sum weight instead of just 1
Keep the current scrutiny format

Proto name conflict

We are still having this warning.

2021/04/29 12:04:37 WARNING: proto: file "vochain/vochain.proto" has a name conflict over dvote.types.v1.UNKNOWN
A future release will panic on registration conflicts. See:

bug: census import is called twice

Describe the bug

Census import queue is trying to download twice the same census

Expected behavior
census should only be imported once

Additional context

feature: drop parts of the StateDB

Describe the feature
The current implementation of the StateDB stores all the state forever. We are working on a StateDB refactor that supports dynamic levels of trees. One of these trees will be the CensusTree for a rolling census. Once the process has ended, the CensusTree could be deleted (and only the root kept) to free space.

Motivation

Free space used by the StateDB when the data is no longer needed.

Proposal
In depth explanation, if required, or a clear and concise description of what the feature actually is.

Add a DropPrefix(prefix []byte) error method in the db.Database interface. Badger already supports this: https://pkg.go.dev/github.com/dgraph-io/badger/v3#DB.DropPrefix
Add a Drop() method to the statedb.Tree struct.

Components affected

add an integration test to ensure we can sync a node properly

In the past few weeks, we've merged changes that broke a node syncing with the vochain. For example, see #268 which fixed one of them.

We should have an integration test that ensures we don't break this again. I think it should cover two scenarios:

Syncing a node from scratch, with no existing data.
Stopping a node and starting it up again, to see that it does a "partial sync" from the last point as expected.

feature: rename and extend getProcessMeta()

Describe the feature
In order to make getProcessMeta() useful for the client, we'd need to extend the fields to:

metadata
startBlock
endBlock
sourceNetworkId
entityIndex

Also rename getProcessMeta to getProcessHeader

Motivation
Make client more efficient.

feature: Bring back VochainInfo.{voteTreeSize,votesPerMinute}

Describe the feature

In this PR #260 the arbo-based StateDB is integrated into the vochain. In this new StateDB there's a vote tree for each process, so having VochainInfo.VoteTreeSize doesn't make sense anymore. We could add VochainInfo.VoteCount. Also VochainInfo.VotesPerMinute is not calculated after the PR. Having those values back needs a different approach: https://github.com/vocdoni/vocdoni-node/pull/260/files#diff-7a5bae6fe8a78550ba0c5c132fea65bf4ecd7c06d64abac9b9efe95ee8a5a891R172

  	// NOTE: votes are now stored separately for each
  	// process, so there's no automatic way to get the
  	// total number of votes.  If having this value is
  	// desirable, we can add a counter in the State (stored
  	// in Storage)

feature: unify routers

Describe the feature
Currently there are two routers on vocdoni-node, the current used one on /router and the one included in multirpc.

Use the multirpc router (which is generic) and remove the custom /router package

Motivation
Simplify code and use a generic router which might be imported by third-party repositories.

By replacing the default value to False (DVOTE_VOCHAINCONFIG_IMPORTPREVIOUSCENSUS=False), the error disappears.

Decide hash function for non-poseidon subTrees used in State

I arbitrarily chose sha256 for the non-poseidon subTrees used in the State via the StateDB. But maybe using blake2b makes more sense because blake2b supposedly is faster than sha256 (see https://www.blake2.net/)
See

vocdoni-node/vochain/state.go

Line 100 in 8a15bd0

HashFunc: arbo.HashFunctionSha256,

We still have some time to make this decision.

feature: enable tendermint state sync

Describe the feature
Currently our vocdoni-node implementation uses fast-sync for synchronizing the blockchain. Fast sync is about downloading the full set of raw transactions and execute them one-by-one until the last state is reached.

This is a safe method but also slow. Since Tendermint v0.34, a new sync method named state-sync is available. This method trust a set of archive nodes available on the network in order to synchronize the last state by downloading snapshots. So the full set of transactions do not need to be executed.

Motivation
Make the blockchain boot-strapping much faster and enable slow-end machines to contribute as full nodes.

Proposal
Implement state sync

Components affected
The "vochain" package from this repository.
Specifically the already declared methods here:

vocdoni-node/vochain/app.go

Lines 224 to 236 in 0fc9f68

           	return abcitypes.ResponseApplySnapshotChunk{} 
        
           } 
        
           func (app *BaseApplication) ListSnapshots(req abcitypes.RequestListSnapshots) abcitypes.ResponseListSnapshots { 
        
           	return abcitypes.ResponseListSnapshots{} 
        
           } 
        
           func (app *BaseApplication) LoadSnapshotChunk(req abcitypes.RequestLoadSnapshotChunk) abcitypes.ResponseLoadSnapshotChunk { 
        
           	return abcitypes.ResponseLoadSnapshotChunk{} 
        
           } 
        
           func (app *BaseApplication) OfferSnapshot(req abcitypes.RequestOfferSnapshot) abcitypes.ResponseOfferSnapshot { 
        
           	return abcitypes.ResponseOfferSnapshot{} 
        
           }

Proposal
Copy&Paste the current multirpc to vocdoni-node/multirpc

Components affected
vocdoni-node vocdoni-manager blind-ca multirpc

Constraints & Assumptions
All paths from vocdoni-node and multirpc need to be adapted.

feature: improve scrutinizer.WalkEnvelopes use of block cache

Describe the feature
WalkEnvelopes executes a callback on each envelope belonging to a given process. To fetch each envelope, it loops through all VoteReferences belonging to a given processId in the badgerhold database. It then fetches the vote transaction referenced by this VoteReference, which includes loading the entire block containing that transaction, either from the database or the block cache.

This is an inefficient use of the LRU block cache. VoteReferences are not sorted by block height, meaning one block could include transactions at various points in our loop through VoteReferences. For a process spanning a sufficient number of blocks, and with a small block cache size, we could easily load a block X to the cache to fetch a vote transaction it contains, load a bunch of other blocks and kick X from the cache, and then load block X back into the cache to fetch another vote transaction it contains. This could happen many times. Ideally, each block should only be loaded to the cache a maximum of 1 time during this process, and all of its vote transactions should be fetched before it's removed from the cache.

Proposal
One of the following

sort the VoteReference query by block height: badgerhold.Where("ProcessID").Eq(processId).Index("ProcessID").SortBy("Height")

Using badgerhold, this would likely be a worse trade-off for performance.

increase the size of the block cache

This would improve the situation, but the issue would still apply for sufficiently large processes.

something else more complicated

Components affected

Scrutinizer

Constraints & Assumptions

Our use of badgerhold is a constraint here. It may be worth it to revisit this issue once we've moved to a different/improved database design.

Describe the feature

Quick refactor on types.BigInt

Context on the PR conversation: #249

feature: integrate the Graph

Describe the feature
Use the graph for the Gateway API: https://thegraph.com

Motivation
Become more standard and allow the Gateway API to be reached via p2p

Proposal
Instead of using our custom API service, integrate The Graph.

Components affected
Gateway/Router.

Constraints & Assumptions
A previous research on how to do it would be required.

feature: oracle web3 redundance

Describe the feature
Currently the Oracle only supports a single --w3External endpoint. We might extend the flag to be a list of endpoints and switch from one to another if there are connection issues.

Motivation
Make the Oracle more resilient.

Proposal
A fallback pool mechanism is required. Stick to the first defined endpoint and if it fails, use the next one. Start over if there is no next one.

Components affected
Oracle.

Vochain Explorer

Implement a block explorer for the Tendermint based Vocdoni blockchain (vochain).

There is an existing old tendermint block explorer that might be useful to look at, the code can be found here.

In order to test it locally a testsuit docker-compose can be started as shown in the developer starting guide.

The file ./src/store/modules/blockchain.js of the vochain-explorer should be modified as follows:

const state = {
  rpc: "http://127.0.0.1:26681",

Then the explorer can be compiled and executed:

yarn
yarn serve

The tendermint RPC API should be used for basic blockchain information (validators, number of blocks, etc).

And the Gateway API on websockets port 9090 should be used for specific Vocdoni information (such as getProcessList, getEnvelopeStatus, etc)

The block explorer should allow:

search tx/block by hash
see pending and already valid txs
Clearly distinguish between different kinds of txs (by colour/name ?)
see current blockchain height, hash, validators, block number, appVersion, Max block size, chainID (tendermint API)
see the raw/json transactions contained inside a block (tendermint API)
see voting process, entities, votes and results (Gateway API) --> Extended version (near future)

Basic information regarding the Vochain can be found here (OUTDATED but mostly valid) .
