sanket1729: How can decoderawtransaction RPC know reqSigs if the output scriptpubkey is p2sh/p2wsh? I think it is returning 1 everytime.
sipa: sanket1729: it only works for bare multisig
sipa: we should probably just remove it

The output parameter for reqSigs is confusing as it outputs 1 for all scripts but bare multisig in the scriptpubkey. Considering the limited applicab

The app_get0_propq (from apps/lib/apps.c) is used throughout many openssl apps to define propq used to fetch the algorithms. Currently, it just returns NULL and its comment says "TODO(3.0): Make this an environment variable if required".
If a provider is used that does not implement all algorithms (e.g. reuses STORE from the default one) the propq needs to be defined to fetch the right implemen

Background

When a node has multiple private channels with the same peer, the hop hints in their payment requests will be populated with multiple channels. The purpose of these hop hints is to specify the next node's key and indicate the fees and cltv delta needed for route construction.

In pathfinding, due to non-strict forwarding, an LND node paying to this destination will only use the

Problem:

A common pattern is:

GUARD(s2n_stuffer_skip_write(stuffer, bytes_to_write));
uint8_t* ptr = suffer->blob.data + stuffer->write_cursor - bytes_to_write;

which could be simplified.

Solution:

*ptr could be an *out parameter to s2n_stuffer_skip_write

  • Does this change what S2N sends over the wire? No.
  • Does this change any public APIs? No.

We will be supporting v0.33 till the next major release (0.35). We should bump golangci-lint version to the latest version to fix ci failures. In doing so many linting errors will arise, these should be cleaned up in the same PR.

This is an easy first contribution to Tendermint, if you are looking to get your hands dirty :)

Clients that support multiple server connections would like to have a way to decide which server connection is best able to handle a query. Servers currently "sort of" expose their load as fees, but there's no real exposure of server load in a useful way. Some parameter should be added to the "server" publication stream that clients can just compare across servers to decide which is most likely to

HElib is an open-source software library that implements homomorphic encryption. It supports the BGV scheme with bootstrapping and the Approximate Number CKKS scheme. HElib also includes optimizations for efficient homomorphic evaluation, focusing on effective use of ciphertext packing techniques and on the Gentry-Halevi-Smart optimizations.
