CHANGELOG.md View File

@ -7,7 +7,6 @@ BREAKING CHANGES:
- Upgrade consensus for more real-time use of evidence
FEATURES:
- Peer reputation management
- Use the chain as its own CA for nodes and validators
- Tooling to run multiple blockchains/apps, possibly in a single process
- State syncing (without transaction replay)
@ -25,19 +24,66 @@ BUG FIXES:
- Graceful handling/recovery for apps that have non-determinism or fail to halt
- Graceful handling/recovery for violations of safety, or liveness
## 0.17.0 (TBD)
## 0.18.0 (April 6th, 2018)
BREAKING:
- [genesis] rename `app_options` to `app_state`
- [types] Merkle tree uses different encoding for varints (see tmlibs v0.8.0)
- [types] ValidtorSet.GetByAddress returns -1 if no validator found
- [p2p] require all addresses come with an ID no matter what
- [rpc] Listening address must contain tcp:// or unix:// prefix
FEATURES:
- [rpc] StartHTTPAndTLSServer (not used yet)
- [rpc] Include validator's voting power in `/status`
- [rpc] `/tx` and `/tx_search` responses now include the transaction hash
- [rpc] Include peer NodeIDs in `/net_info`
IMPROVEMENTS:
- [config] exposed `auth_enc` flag to enable/disable encryption
- [config] trim whitespace from elements of lists (like `persistent_peers`)
- [rpc] `/tx_search` results are sorted by height
- [p2p] do not try to connect to ourselves (ok, maybe only once)
- [p2p] seeds respond with a bias towards good peers
BUG FIXES:
- [rpc] fix subscribing using an abci.ResponseDeliverTx tag
- [rpc] fix tx_indexers matchRange
- [rpc] fix unsubscribing (see tmlibs v0.8.0)
## 0.17.1 (March 27th, 2018)
BUG FIXES:
- [types] Actually support `app_state` in genesis as `AppStateJSON`
## 0.17.0 (March 27th, 2018)
BREAKING:
- [types] WriteSignBytes -> SignBytes
IMPROVEMENTS:
- [all] renamed `dummy` (`persistent_dummy`) to `kvstore` (`persistent_kvstore`) (name "dummy" is deprecated and will not work in the next breaking release)
- [docs] note on determinism (docs/determinism.rst)
- [genesis] `app_options` field is deprecated. please rename it to `app_state` in your genesis file(s). `app_options` will not work in the next breaking release
- [p2p] dial seeds directly without potential peers
- [p2p] exponential backoff for addrs in the address book
- [p2p] mark peer as good if it contributed enough votes or block parts
- [p2p] stop peer if it sends incorrect data, msg to unknown channel, msg we did not expect
- [p2p] when `auth_enc` is true, all dialed peers must have a node ID in their address
- [all] renamed `dummy` (`persistent_dummy`) to `kvstore`
(`persistent_kvstore`) (name "dummy" is deprecated and will not work in
release after this one)
- [spec] various improvements
- switched from glide to dep internally for package management
- [wire] prep work for upgrading to new go-wire (which is now called go-amino)
FEATURES:
- [config] exposed `auth_enc` flag to enable/disable encryption
- [config] added the `--p2p.private_peer_ids` flag and `PrivatePeerIDs` config variable (see config for description)
- [rpc] added `/health` endpoint, which returns empty result for now
- [types/priv_validator] new format and socket client, allowing for remote signing
BUG FIXES:
- [consensus] fix liveness bug by introducing ValidBlock mechanism
## 0.16.0 (February 20th, 2017)
## 0.16.0 (February 20th, 2018)
BREAKING CHANGES:
- [config] use $TMHOME/config for all config and json files

@ -16,7 +16,21 @@ In the context of Tendermint, time is of type int64 and denotes UNIX time in mil
corresponds to the number of milliseconds since January 1, 1970. Before defining rules that need to be enforced by the
Tendermint consensus protocol, so the properties above holds, we introduce the following definition:
- median of a set of `Vote` messages is equal to the median of `Vote.Time` fields of the corresponding `Vote` messages
- median of a set of `Vote` messages is equal to the median of `Vote.Time` fields of the corresponding `Vote` messages,
where the value of `Vote.Time` is counted number of times proportional to the process voting power. As in Tendermint
the voting power is not uniform (one process one vote), a vote message is actually an aggregator of the same votes whose
number is equal to the voting power of the process that has casted the corresponding votes message.
Let's consider the following example:
- we have four processes p1, p2, p3 and p4, with the following voting power distribution (p1, 23), (p2, 27), (p3, 10)
and (p4, 10). The total voting power is 70 (`N = 3f+1`, where `N` is the total voting power, and `f` is the maximum voting
power of the faulty processes), so we assume that the faulty processes have at most 23 of voting power.
Furthermore, we have the following vote messages in some LastCommit field (we ignore all fields except Time field):
- (p1, 100), (p2, 98), (p3, 1000), (p4, 500). We assume that p3 and p4 are faulty processes. Let's assume that the
`block.LastCommit` message contains votes of processes p2, p3 and p4. Median is then chosen the following way:
the value 98 is counted 27 times, the value 1000 is counted 10 times and the value 500 is counted also 10 times.
So the median value will be the value 98. No matter what set of messages with at least `2f+1` voting power we
choose, the median value will always be between the values sent by correct processes.
We ensure Time Monotonicity and Time Validity properties by the following rules:

# Light client
A light client is a process that connects to the Tendermint Full Node(s) and then tries to verify the Merkle proofs
about the blockchain application. In this document we describe mechanisms that ensures that the Tendermint light client
has the same level of security as Full Node processes (without being itself a Full Node).
To be able to validate a Merkle proof, a light client needs to validate the blockchain header that contains the root app hash.
Validating a blockchain header in Tendermint consists in verifying that the header is committed (signed) by >2/3 of the
voting power of the corresponding validator set. As the validator set is a dynamic set (it is changing), one of the
core functionality of the light client is updating the current validator set, that is then used to verify the
blockchain header, and further the corresponding Merkle proofs.
For the purpose of this light client specification, we assume that the Tendermint Full Node exposes the following functions over
Tendermint RPC:
```golang
Header(height int64) (SignedHeader, error) // returns signed header for the given height
Validators(height int64) (ResultValidators, error) // returns validator set for the given height
LastHeader(valSetNumber int64) (SignedHeader, error) // returns last header signed by the validator set with the given validator set number
type SignedHeader struct {
Header Header
Commit Commit
ValSetNumber int64
}
type ResultValidators struct {
BlockHeight int64
Validators []Validator
// time the current validator set is initialised, i.e, time of the last validator change before header BlockHeight
ValSetTime int64
}
```
We assume that Tendermint keeps track of the validator set changes and that each time a validator set is changed it is
being assigned the next sequence number. We can call this number the validator set sequence number. Tendermint also remembers
the Time from the header when the next validator set is initialised (starts to be in power), and we refer to this time
as validator set init time.
Furthermore, we assume that each validator set change is signed (committed) by the current validator set. More precisely,
given a block `H` that contains transactions that are modifying the current validator set, the Merkle root hash of the next
validator set (modified based on transactions from block H) will be in block `H+1` (and signed by the current validator
set), and then starting from the block `H+2`, it will be signed by the next validator set.
Note that the real Tendermint RPC API is slightly different (for example, response messages contain more data and function
names are slightly different); we shortened (and modified) it for the purpose of this document to make the spec more
clear and simple. Furthermore, note that in case of the third function, the returned header has `ValSetNumber` equals to
`valSetNumber+1`.
Locally, light client manages the following state:
```golang
valSet []Validator // current validator set (last known and verified validator set)
valSetNumber int64 // sequence number of the current validator set
valSetHash []byte // hash of the current validator set
valSetTime int64 // time when the current validator set is initialised
```
The light client is initialised with the trusted validator set, for example based on the known validator set hash,
validator set sequence number and the validator set init time.
The core of the light client logic is captured by the VerifyAndUpdate function that is used to 1) verify if the given header is valid,
and 2) update the validator set (when the given header is valid and it is more recent than the seen headers).
```golang
VerifyAndUpdate(signedHeader SignedHeader):
assertThat signedHeader.valSetNumber >= valSetNumber
if isValid(signedHeader) and signedHeader.Header.Time <= valSetTime + UNBONDING_PERIOD then
setValidatorSet(signedHeader)
return true
else
updateValidatorSet(signedHeader.ValSetNumber)
return VerifyAndUpdate(signedHeader)
isValid(signedHeader SignedHeader):
valSetOfTheHeader = Validators(signedHeader.Header.Height)
assertThat Hash(valSetOfTheHeader) == signedHeader.Header.ValSetHash
assertThat signedHeader is passing basic validation
if votingPower(signedHeader.Commit) > 2/3 * votingPower(valSetOfTheHeader) then return true
else
return false
setValidatorSet(signedHeader SignedHeader):
nextValSet = Validators(signedHeader.Header.Height)
assertThat Hash(nextValSet) == signedHeader.Header.ValidatorsHash
valSet = nextValSet.Validators
valSetHash = signedHeader.Header.ValidatorsHash
valSetNumber = signedHeader.ValSetNumber
valSetTime = nextValSet.ValSetTime
votingPower(commit Commit):
votingPower = 0
for each precommit in commit.Precommits do:
if precommit.ValidatorAddress is in valSet and signature of the precommit verifies then
votingPower += valSet[precommit.ValidatorAddress].VotingPower
return votingPower
votingPower(validatorSet []Validator):
for each validator in validatorSet do:
votingPower += validator.VotingPower
return votingPower
updateValidatorSet(valSetNumberOfTheHeader):
while valSetNumber != valSetNumberOfTheHeader do
signedHeader = LastHeader(valSetNumber)
if isValid(signedHeader) then
setValidatorSet(signedHeader)
else return error
return
```
Note that in the logic above we assume that the light client will always go upward with respect to header verifications,
i.e., that it will always be used to verify more recent headers. In case a light client needs to be used to verify older
headers (go backward) the same mechanisms and similar logic can be used. In case a call to the FullNode or subsequent
checks fail, a light client need to implement some recovery strategy, for example connecting to other FullNode.

## Select Peers to Dial
When we need more peers, we pick them randomly from the addrbook with some

configurable bias for unvetted peers. The bias should be lower when we have fewer peers
and can increase as we obtain more, ensuring that our first peers are more trustworthy,
but always giving us the chance to discover new good peers.
We track the last time we dialed a peer and the number of unsuccessful attempts
we've made. If too many attempts are made, we mark the peer as bad.
Connection attempts are made with exponential backoff (plus jitter). Because
the selection process happens every `ensurePeersPeriod`, we might not end up
dialing a peer for much longer than the backoff duration.
