2022-02-11

Add the TSM identity to Darc The Trusted Secure Module is used by DuoKey to sign messages using a threshold signature scheme. This PR adds support for Darcs to verify those messages. It is used for the Master Thesis protject of Pilar Marxer.

Separate signup node As the conode.c4dt.org is on the switch-node and doesn't have an SMTP server that allows sending of emails without authentication, the signup-service is changed to interact with a byzcoin on a remote node.

2021-11-15

Adding email signup and recovery This PR adds the possibility to create accounts linked to an email. 1. Setup - the system needs to be set up once with an account that is allowed to create new users 2. Signup - by sending an email, the service creates a new user and sends the signup link to the given email 3. Recover - once a user is signed up, they can request a mail to recover their account, and a recover link will be sent to the email stored on the ledger This PR has three parts: - updates to the byzcoin system for convenience - adding needed functions to the personhood/user package - adding service endpoints to the personhood service

protobuf: fix field name for SignerDID

2020-10-19

Make getUpdates behave better (#2392) The previous ByzCoinRPC.getUpdate tried to be smart to cover an error in its use in ByzCoinRPC.getUpdateInstances. The error in getUpdateInstances created a race condition where two quickly updating blocks created two concurrent calls to getUpdates which failed. This PR adds a new field to the ByzCoin.GetUpdates RPC-call that allows it to send updates with regard to a skipchain, and not with regards to a block. This makes getUpdates much simpler. Furthermore it removes the race in getUpdateInstances and waits for each update before accepting new blocks.

Rollup protocol (#2321) * Rollup protocol Previously the leader polled for new transactions. This is inefficient, as new transactions have to wait for the leader to poll. With this PR, the all followers forward transactions directly to the leader. Once the leader has a transaction, he directly starts a new block. Once the new block has been accepted, eventually queued up transactions are also sent. This has been tested to be able to go from old nodes to new nodes on a local machine. * Tharvik's comments

Use js ethereum libs & improve View Method calls (#2332) * Rework to use JS libraries instead of methods of the BEvm service. * Remove no longer needed service methods. * Change `PerformCall` method to use packed arguments instead, simplifying the code and providing support for large integers (BN). * Simplify frontend code by using JS libraries wherever possible. * Clean-up BEvm contract method invocation * Use local conode ReadOnlyStateTrie to call EVM * Update documentation for BEvmInstance methods * remove BEvmInstance.setBEvmRPC() * rename BEvmRPC.performViewMethodCall() to BEvmRPC.callViewMethod() * rename service method to viewCall()

bevm: use bevm_id:contract_address for EVM identity

2020-03-05

bevm: restrict the use of EVM contract identities EVM contract identities can be used only by "synthetic" instructions, generated by the BEvm contract. Direct use of an EVM contract identity to sign an instruction is forbidden and fails verification.

Separate personhood-contract and service For the github.com/c4dt/byzcoin I want to include only the contracts from personhood, but not the service. This PR puts the contracts in its own directory, so that the byzcoin-repository can include only that. Also rewrites the testing of the contracts to not use the service itself, but to test only the contracts, without the whole byzcoin-service around. This could also be applied to other contracts...

Add functionalities to personhood During the OpenHouse2019 demo, a couple of new functionalities have been added: - remove all polls - protect adding of new personhood-gatherings Both functionalities need to be signed off by the conode-key. The personhood/phapp binary can do so when given a private.toml file.

Gaylor's comments

Adding connectivity command to status In order to verify that all nodes can reach each other, the status service gets an additional command connectivity that tests an all nodes to all nodes connectivity. The test can also try multiple list of nodes until all nodes can reach each other. To prevent abuse, the request must be signed by the node that launches the request.

Stabilize calypso test This makes sure that the signer counter will be correct after each step of a Calypso write and read requests.

2019-09-10

RoPaSci calypso contract Implements an extension to the Rock-Paper-Scissors contract by allowing the player 1 to store his move (the pre-hash) encrypted in a CalypsoWrite structure. Player 2 will create a CalypsoRead instance that can be used to recover the pre-hash, even if Player 1 is absent. If Player 2 is absent, Player 1 can still confirm the game and collect the wins. There is a documentation at the beginning of the personhood/contract_ropasci.go file.

Version stored in the state trie This adds the ByzCoin protocol version in the state trie so that contracts have access to it.

Fix instruction hash Make use of the versioning to fix the instruction hash so that block created with the latest version will correctly hash the invoke command name. Fixes #1990

Version stored in the block This adds a version field to the DataHeader. Old blocks will have 0 as value which is the default one. Fixes #1854

Make websockets over HTTPS work Various changes to make websock over HTTPS work better. Fix network.proto to correctly match what the protobuf encoder is doing. Take the new version of onet (fix for URLs ending in slash). scmgr and bcadmin changes to help debug roster contents, including the URL. Docker container includes admin tools now. Better docs on usign built-in TLS. Updated dedis-cothority.toml to reflect reality. The employees.org conode cannot do TLS for the moment, so kick it out of the public cothority.

Implement secure_darc contract The old DARC contract has too much freedom. We need to limit this freedom in two ways to improve security. First, the owner of any DARC should not be allowed to change its rules arbitrarily, he/she is only allowed to change the existing rules. Nevertheless, we still allow a set of authorised parties to add rules. Second, we want to let certain DARCs create new DARCs, but those new DARCs cannot have arbitrary rules. These features are implemented in a new contract called "secure_darc". For the first restriction, we changed the "evolve" command to reject requests that tries to add new rules. We also added a new command "evolve_unrestricted" to let authorised users add rules. For the second restriction, we give an example of how to implement it statically in the contract, which is to reject spawn requests that contains "spawn:darc". Additionally, we explain in the example how to impelement it the same feature dynamically. Since we have more than one contract that can be decoded into a DARC, we add a new parameter into ChainConfig to keep track of these contracts. Fixes #1625

Redefine the contract API to be an interface The callback is now a factory function that turns the existing instance data into a struct that implements byzcoin.Contract. Contract writers are advised to have their contract structures embed byzcoin.BasicContract, so that they only need to redefine the methods they are interested in implementing. Also: Removed InstructionsHash, which was derived data and not useful to keep around.

Fix java tests

Instance versioning API This adds the Java API to get one or several state changes by requesting them to a conode.

Instance history handlers This adds the handlers required to make requests to ask for one or more state changes. It also adds a request to check the validity of a state change by sending back the list of state changes of the same block to compare the hash

Instance versioning protobuf This adds the new fields in the proto files definition to fix the Java and JS tests

Implement signer counter to prevent replay attacks

Added packed=true feature to proto.awk Now, when faced with a []bool (or other native type) the proto files will indicate packed encoding, which was what dedis/protobuf was already doing. Also added a feature to correctly handle references to lower-case types. Fixed blank lines inside of type declarations. Used these fixes to make trie/proto.go work correctly, so that we have one less manually-maintained .proto file. These changes caused expected changes in the personhood.proto file. This means that fields which no one had noticed could not be deserialised can now be handled from JS and Java. Co-developed with Kelong.

2018-11-05

Protobuf fixes: skipchain zigzag encoding and protoc version Do not allow old versions of protoc, so that the .java files do not get changed when we don't want them to be. Fix the encoding of ints in skipchain.proto. If it was automatically generated, proto.awk would have taken care of this. Deploy a new version of cothority-js with the fixed protobuf decoding rules. Document the manually-maintained .proto files better.

More improvements to Auth Prox Better docs. Correctly testing threshold signing in auth prox service test. Sign partial sigs with conode private key. Check signature of partials as they arrive. Use the new ServerIdentity.URL field in order to correctly check for secure connection for enrolling. Move AuthProxProto to the corerct place. Update network.proto to reflect new URL field in ServerIdentity. Other fixes as requested in code review.

Fix authprox proto.go file to compile for JS/Java Introduced not-so-gross workaround for the fact that some types we need from Kyber are not available in our proto files.
