This implies that 1/3+ of honest nodes are +still locked at round `R' > R`. These locked validators will remain +locked until they see a PoLC at `R' > R`, but this won't happen because +1/3+ are locked and honest, so at most -2/3 are available to vote for +anything other than `B`. + +### Proof of Liveness + +If 1/3+ honest validators are locked on two different blocks from +different rounds, a proposers' `PoLC-Round` will eventually cause nodes +locked from the earlier round to unlock. Eventually, the designated +proposer will be one that is aware of a PoLC at the later round. Also, +`timeoutProposalR` increments with round `R`, while the size of a +proposal are capped, so eventually the network is able to "fully gossip" +the whole proposal (e.g. the block & PoLC). + +### Proof of Fork Accountability + +Define the JSet (justification-vote-set) at height `H` of a validator +`V1` to be all the votes signed by the validator at `H` along with +justification PoLC prevotes for each lock change. For example, if `V1` +signed the following precommits: `Precommit(B1 @ round 0)`, +`Precommit( @ round 1)`, `Precommit(B2 @ round 4)` (note that no +precommits were signed for rounds 2 and 3, and that's ok), +`Precommit(B1 @ round 0)` must be justified by a PoLC at round 0, and +`Precommit(B2 @ round 4)` must be justified by a PoLC at round 4; but +the precommit for `` at round 1 is not a lock-change by definition +so the JSet for `V1` need not include any prevotes at round 1, 2, or 3 +(unless `V1` happened to have prevoted for those rounds). + +Further, define the JSet at height `H` of a set of validators `VSet` to +be the union of the JSets for each validator in `VSet`. For a given +commit by honest validators at round `R` for block `B` we can construct +a JSet to justify the commit for `B` at `R`. We say that a JSet +*justifies* a commit at `(H,R)` if all the committers (validators in the +commit-set) are each justified in the JSet with no duplicitous vote +signatures (by the committers). + +- **Lemma**: When a fork is detected by the existence of two + conflicting [commits](./validators.html#commiting-a-block), the + union of the JSets for both commits (if they can be compiled) must + include double-signing by at least 1/3+ of the validator set. + **Proof**: The commit cannot be at the same round, because that + would immediately imply double-signing by 1/3+. Take the union of + the JSets of both commits. If there is no double-signing by at least + 1/3+ of the validator set in the union, then no honest validator + could have precommitted any different block after the first commit. + Yet, +2/3 did. Reductio ad absurdum. + +As a corollary, when there is a fork, an external process can determine +the blame by requiring each validator to justify all of its round votes. +Either we will find 1/3+ who cannot justify at least one of their votes, +and/or, we will find 1/3+ who had double-signed. + +### Alternative algorithm + +Alternatively, we can take the JSet of a commit to be the "full commit". +That is, if light clients and validators do not consider a block to be +committed unless the JSet of the commit is also known, then we get the +desirable property that if there ever is a fork (e.g. there are two +conflicting "full commits"), then 1/3+ of the validators are immediately +punishable for double-signing. + +There are many ways to ensure that the gossip network efficiently share +the JSet of a commit. One solution is to add a new message type that +tells peers that this node has (or does not have) a +2/3 majority for B +(or) at (H,R), and a bitarray of which votes contributed towards that +majority. Peers can react by responding with appropriate votes. + +We will implement such an algorithm for the next iteration of the +Tendermint consensus protocol. + +Other potential improvements include adding more data in votes such as +the last known PoLC round that caused a lock change, and the last voted +round/step (or, we may require that validators not skip any votes). This +may make JSet verification/gossip logic easier to implement. + +### Censorship Attacks + +Due to the definition of a block +[commit](../../tendermint-core/validator.md#commiting-a-block), any 1/3+ coalition of +validators can halt the blockchain by not broadcasting their votes. Such +a coalition can also censor particular transactions by rejecting blocks +that include these transactions, though this would result in a +significant proportion of block proposals to be rejected, which would +slow down the rate of block commits of the blockchain, reducing its +utility and value. The malicious coalition might also broadcast votes in +a trickle so as to grind blockchain block commits to a near halt, or +engage in any combination of these attacks. + +If a global active adversary were also involved, it can partition the +network in such a way that it may appear that the wrong subset of +validators were responsible for the slowdown. This is not just a +limitation of Tendermint, but rather a limitation of all consensus +protocols whose network is potentially controlled by an active +adversary. + +### Overcoming Forks and Censorship Attacks + +For these types of attacks, a subset of the validators through external +means should coordinate to sign a reorg-proposal that chooses a fork +(and any evidence thereof) and the initial subset of validators with +their signatures. Validators who sign such a reorg-proposal forego its +collateral on all other forks. Clients should verify the signatures on +the reorg-proposal, verify any evidence, and make a judgement or prompt +the end-user for a decision. For example, a phone wallet app may prompt +the user with a security warning, while a refrigerator may accept any +reorg-proposal signed by +1/2 of the original validators. + +No non-synchronous Byzantine fault-tolerant algorithm can come to +consensus when 1/3+ of validators are dishonest, yet a fork assumes that +1/3+ of validators have already been dishonest by double-signing or +lock-changing without justification. So, signing the reorg-proposal is a +coordination problem that cannot be solved by any non-synchronous +protocol (i.e. automatically, and without making assumptions about the +reliability of the underlying network). It must be provided by means +external to the weakly-synchronous Tendermint consensus algorithm. For +now, we leave the problem of reorg-proposal coordination to human +coordination via internet media. Validators must take care to ensure +that there are no significant network partitions, to avoid situations +where two conflicting reorg-proposals are signed. + +Assuming that the external coordination medium and protocol is robust, +it follows that forks are less of a concern than [censorship +attacks](#censorship-attacks). diff --git a/docs/specification/block-structure.rst b/docs/specification/block-structure.rst deleted file mode 100644 index 7d8f3464c..000000000 --- a/docs/specification/block-structure.rst +++ /dev/null @@ -1,218 +0,0 @@ -Block Structure -=============== - -The tendermint consensus engine records all agreements by a -supermajority of nodes into a blockchain, which is replicated among all -nodes.

Thus, getting the Commit data and verifying the votes is -extremely important. - -As mentioned above, in order to find the ``precommit votes`` for block -header ``H``, we need to query block ``H+1``. Then we need to check the -votes, make sure they really are for that block, and properly formatted. -Much of this code is implemented in Go in the -`light-client `__ package. -If you look at the code, you will notice that we need to provide the -``chainID`` of the blockchain in order to properly calculate the votes. -This is to protect anyone from swapping votes between chains to fake (or -frame) a validator.

The light client is responsible for maintaining a -set of validators that we trust. Each vote only stores the validators -``Address``, as well as the ``Signature``. Assuming we have a local copy -of the trusted validator set, we can look up the ``Public Key`` of the -validator given its ``Address``, then verify that the ``Signature`` -matches the ``SignBytes`` and ``Public Key``. Then we sum up the total -voting power of all validators, whose votes fulfilled all these -stringent requirements. If the total number of voting power for a single -block is greater than 2/3 of all voting power, then we can finally trust -the block header, the AppHash, and the proof we got from the ABCI -application. - -Vote Sign Bytes -^^^^^^^^^^^^^^^ - -The ``sign-bytes`` of a vote is produced by taking a -`stable-json `__-like -deterministic JSON `wire <./wire-protocol.html>`__ encoding of -the vote (excluding the ``Signature`` field), and wrapping it with -``{"chain_id":"my_chain","vote":...}``. - -For example, a precommit vote might have the following ``sign-bytes``: - -.. code:: json - - {"chain_id":"my_chain","vote":{"block_hash":"611801F57B4CE378DF1A3FFF1216656E89209A99","block_parts_header":{"hash":"B46697379DBE0774CC2C3B656083F07CA7E0F9CE","total":123},"height":1234,"round":1,"type":2}} - -Block Hash -~~~~~~~~~~ - -The `block -hash `__ -is the `Simple Tree hash <./merkle.html#simple-tree-with-dictionaries>`__ -of the fields of the block ``Header`` encoded as a list of -``KVPair``\ s. - -Transaction -~~~~~~~~~~~ - -A transaction is any sequence of bytes. It is up to your -ABCI application to accept or reject transactions. - -BlockID -~~~~~~~ - -Many of these data structures refer to the -`BlockID `__, -which is the ``BlockHash`` (hash of the block header, also referred to -by the next block) along with the ``PartSetHeader``.

Also, ``timeoutProposalR`` increments with round ``R``, while the -size of a proposal are capped, so eventually the network is able to -"fully gossip" the whole proposal (e.g. the block & PoLC). - -Proof of Fork Accountability -~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Define the JSet (justification-vote-set) at height ``H`` of a validator -``V1`` to be all the votes signed by the validator at ``H`` along with -justification PoLC prevotes for each lock change. For example, if ``V1`` -signed the following precommits: ``Precommit(B1 @ round 0)``, -``Precommit( @ round 1)``, ``Precommit(B2 @ round 4)`` (note that -no precommits were signed for rounds 2 and 3, and that's ok), -``Precommit(B1 @ round 0)`` must be justified by a PoLC at round 0, and -``Precommit(B2 @ round 4)`` must be justified by a PoLC at round 4; but -the precommit for ```` at round 1 is not a lock-change by -definition so the JSet for ``V1`` need not include any prevotes at round -1, 2, or 3 (unless ``V1`` happened to have prevoted for those rounds). - -Further, define the JSet at height ``H`` of a set of validators ``VSet`` -to be the union of the JSets for each validator in ``VSet``. For a given -commit by honest validators at round ``R`` for block ``B`` we can -construct a JSet to justify the commit for ``B`` at ``R``. We say that a -JSet *justifies* a commit at ``(H,R)`` if all the committers (validators -in the commit-set) are each justified in the JSet with no duplicitous -vote signatures (by the committers). - -- **Lemma**: When a fork is detected by the existence of two - conflicting `commits <./validators.html#commiting-a-block>`__, - the union of the JSets for both commits (if they can be compiled) - must include double-signing by at least 1/3+ of the validator set. - **Proof**: The commit cannot be at the same round, because that would - immediately imply double-signing by 1/3+. Take the union of the JSets - of both commits. If there is no double-signing by at least 1/3+ of - the validator set in the union, then no honest validator could have - precommitted any different block after the first commit. Yet, +2/3 - did. Reductio ad absurdum. - -As a corollary, when there is a fork, an external process can determine -the blame by requiring each validator to justify all of its round votes. -Either we will find 1/3+ who cannot justify at least one of their votes, -and/or, we will find 1/3+ who had double-signed. - -Alternative algorithm -~~~~~~~~~~~~~~~~~~~~~ - -Alternatively, we can take the JSet of a commit to be the "full commit". -That is, if light clients and validators do not consider a block to be -committed unless the JSet of the commit is also known, then we get the -desirable property that if there ever is a fork (e.g. there are two -conflicting "full commits"), then 1/3+ of the validators are immediately -punishable for double-signing. - -There are many ways to ensure that the gossip network efficiently share -the JSet of a commit. One solution is to add a new message type that -tells peers that this node has (or does not have) a +2/3 majority for B -(or ) at (H,R), and a bitarray of which votes contributed towards that -majority. Peers can react by responding with appropriate votes. - -We will implement such an algorithm for the next iteration of the -Tendermint consensus protocol. - -Other potential improvements include adding more data in votes such as -the last known PoLC round that caused a lock change, and the last voted -round/step (or, we may require that validators not skip any votes). This -may make JSet verification/gossip logic easier to implement. - -Censorship Attacks -~~~~~~~~~~~~~~~~~~ - -Due to the definition of a block -`commit `__, any 1/3+ -coalition of validators can halt the blockchain by not broadcasting -their votes. Such a coalition can also censor particular transactions by -rejecting blocks that include these transactions, though this would -result in a significant proportion of block proposals to be rejected, -which would slow down the rate of block commits of the blockchain, -reducing its utility and value. The malicious coalition might also -broadcast votes in a trickle so as to grind blockchain block commits to -a near halt, or engage in any combination of these attacks. - -If a global active adversary were also involved, it can partition the -network in such a way that it may appear that the wrong subset of -validators were responsible for the slowdown. This is not just a -limitation of Tendermint, but rather a limitation of all consensus -protocols whose network is potentially controlled by an active -adversary. - -Overcoming Forks and Censorship Attacks -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -For these types of attacks, a subset of the validators through external -means should coordinate to sign a reorg-proposal that chooses a fork -(and any evidence thereof) and the initial subset of validators with -their signatures. Validators who sign such a reorg-proposal forego its -collateral on all other forks. Clients should verify the signatures on -the reorg-proposal, verify any evidence, and make a judgement or prompt -the end-user for a decision. For example, a phone wallet app may prompt -the user with a security warning, while a refrigerator may accept any -reorg-proposal signed by +1/2 of the original validators. - -No non-synchronous Byzantine fault-tolerant algorithm can come to -consensus when 1/3+ of validators are dishonest, yet a fork assumes that -1/3+ of validators have already been dishonest by double-signing or -lock-changing without justification. So, signing the reorg-proposal is a -coordination problem that cannot be solved by any non-synchronous -protocol (i.e. automatically, and without making assumptions about the -reliability of the underlying network). It must be provided by means -external to the weakly-synchronous Tendermint consensus algorithm. For -now, we leave the problem of reorg-proposal coordination to human -coordination via internet media. Validators must take care to ensure -that there are no significant network partitions, to avoid situations -where two conflicting reorg-proposals are signed. - -Assuming that the external coordination medium and protocol is robust, -it follows that forks are less of a concern than `censorship -attacks <#censorship-attacks>`__. diff --git a/docs/specification/corruption.rst b/docs/specification/corruption.rst deleted file mode 100644 index 6ae19fb18..000000000 --- a/docs/specification/corruption.rst +++ /dev/null @@ -1,70 +0,0 @@ -Corruption -========== - -Important step --------------- - -Make sure you have a backup of the Tendermint data directory. - -Possible causes ---------------- - -Remember that most corruption is caused by hardware issues: - -- RAID controllers with faulty / worn out battery backup, and an unexpected power loss -- Hard disk drives with write-back cache enabled, and an unexpected power loss -- Cheap SSDs with insufficient power-loss protection, and an unexpected power-loss -- Defective RAM -- Defective or overheating CPU(s) - -Other causes can be: - -- Database systems configured with fsync=off and an OS crash or power loss -- Filesystems configured to use write barriers plus a storage layer that ignores write barriers.

This can be a little confusing, but we must also consider that +the `Header` also contains the `LastCommitHash`. It would be impossible +for a Header to include the commits that sign it, as it would cause an +infinite loop here. But when we get block `H`, we find +`Header.LastCommitHash`, which must match the hash of `LastCommit`. + +## Header + +The +[Header](https://godoc.org/github.com/tendermint/tendermint/types#Header) +contains lots of information (follow link for up-to-date info). Notably, +it maintains the `Height`, the `LastBlockID` (to make it a chain), and +hashes of the data, the app state, and the validator set. This is +important as the only item that is signed by the validators is the +`Header`, and all other data must be validated against one of the merkle +hashes in the `Header`. + +The `DataHash` can provide a nice check on the +[Data](https://godoc.org/github.com/tendermint/tendermint/types#Data) +returned in this same block. If you are subscribed to new blocks, via +tendermint RPC, in order to display or process the new transactions you +should at least validate that the `DataHash` is valid. If it is +important to verify autheniticity, you must wait for the `LastCommit` +from the next block to make sure the block header (including `DataHash`) +was properly signed. + +The `ValidatorHash` contains a hash of the current +[Validators](https://godoc.org/github.com/tendermint/tendermint/types#Validator). +Tracking all changes in the validator set is complex, but a client can +quickly compare this hash with the [hash of the currently known +validators](https://godoc.org/github.com/tendermint/tendermint/types#ValidatorSet.Hash) +to see if there have been changes. + +The `AppHash` serves as the basis for validating any merkle proofs that +come from the ABCI application. It represents the state of the actual +application, rather that the state of the blockchain itself. This means +it's necessary in order to perform any business logic, such as verifying +an account balance. + +**Note** After the transactions are committed to a block, they still +need to be processed in a separate step, which happens between the +blocks. If you find a given transaction in the block at height `H`, the +effects of running that transaction will be first visible in the +`AppHash` from the block header at height `H+1`. + +Like the `LastCommit` issue, this is a requirement of the immutability +of the block chain, as the application only applies transactions *after* +they are commited to the chain. + +## Commit + +The +[Commit](https://godoc.org/github.com/tendermint/tendermint/types#Commit) +contains a set of +[Votes](https://godoc.org/github.com/tendermint/tendermint/types#Vote) +that were made by the validator set to reach consensus on this block. +This is the key to the security in any PoS system, and actually no data +that cannot be traced back to a block header with a valid set of Votes +can be trusted. Thus, getting the Commit data and verifying the votes is +extremely important. + +As mentioned above, in order to find the `precommit votes` for block +header `H`, we need to query block `H+1`. Then we need to check the +votes, make sure they really are for that block, and properly formatted. +Much of this code is implemented in Go in the +[light-client](https://github.com/tendermint/light-client) package. If +you look at the code, you will notice that we need to provide the +`chainID` of the blockchain in order to properly calculate the votes. +This is to protect anyone from swapping votes between chains to fake (or +frame) a validator. Also note that this `chainID` is in the +`genesis.json` from *Tendermint*, not the `genesis.json` from the +basecoin app ([that is a different +chainID...](https://github.com/cosmos/cosmos-sdk/issues/32)). + +Once we have those votes, and we calculated the proper [sign +bytes](https://godoc.org/github.com/tendermint/tendermint/types#Vote.WriteSignBytes) +using the chainID and a [nice helper +function](https://godoc.org/github.com/tendermint/tendermint/types#SignBytes), +we can verify them. The light client is responsible for maintaining a +set of validators that we trust. Each vote only stores the validators +`Address`, as well as the `Signature`. Assuming we have a local copy of +the trusted validator set, we can look up the `Public Key` of the +validator given its `Address`, then verify that the `Signature` matches +the `SignBytes` and `Public Key`. Then we sum up the total voting power +of all validators, whose votes fulfilled all these stringent +requirements. If the total number of voting power for a single block is +greater than 2/3 of all voting power, then we can finally trust the +block header, the AppHash, and the proof we got from the ABCI +application. + +### Vote Sign Bytes + +The `sign-bytes` of a vote is produced by taking a +[stable-json](https://github.com/substack/json-stable-stringify)-like +deterministic JSON [wire](./wire-protocol.html) encoding of the vote +(excluding the `Signature` field), and wrapping it with +`{"chain_id":"my_chain","vote":...}`. + +For example, a precommit vote might have the following `sign-bytes`: + +``` +{"chain_id":"my_chain","vote":{"block_hash":"611801F57B4CE378DF1A3FFF1216656E89209A99","block_parts_header":{"hash":"B46697379DBE0774CC2C3B656083F07CA7E0F9CE","total":123},"height":1234,"round":1,"type":2}} +``` + +## Block Hash + +The [block +hash](https://godoc.org/github.com/tendermint/tendermint/types#Block.Hash) +is the [Simple Tree hash](./merkle.html#simple-tree-with-dictionaries) +of the fields of the block `Header` encoded as a list of `KVPair`s. + +## Transaction + +A transaction is any sequence of bytes. It is up to your ABCI +application to accept or reject transactions. + +## BlockID + +Many of these data structures refer to the +[BlockID](https://godoc.org/github.com/tendermint/tendermint/types#BlockID), +which is the `BlockHash` (hash of the block header, also referred to by +the next block) along with the `PartSetHeader`. The `PartSetHeader` is +explained below and is used internally to orchestrate the p2p +propogation. For clients, it is basically opaque bytes, but they must +match for all votes. + +## PartSetHeader + +The +[PartSetHeader](https://godoc.org/github.com/tendermint/tendermint/types#PartSetHeader) +contains the total number of pieces in a +[PartSet](https://godoc.org/github.com/tendermint/tendermint/types#PartSet), +and the Merkle root hash of those pieces. + +## PartSet + +PartSet is used to split a byteslice of data into parts (pieces) for +transmission.
