### Problem
The blockchain scalability problem has 4 facets:
1. **Bandwidth** needed to receive all transactions happening on the network.
2. **CPU cost** to verify all these transactions.
3. **…

Define required functions and their properties for the kind of cryptographic accumulator which IBC state inclusion proofs will require. Any accumulator which instantiates these properties (e.g. Merkle…

`state.latest_block_header.signature` is different between producing and processing a block and this is causing block processing to fail because of a mismatch on `block.state_root`.

There is concern that 80 bits of security with truncated 20 byte sha256 is insufficient. We need to do a cost analysis of the cost to break truncated levels of sha256 (i.e. cost per asic + electricity…

Hi all,
I am proposing that we progressively introduce eXtended Merkle Signature Scheme (XMSS) in Interledger as one of the cryptographic signing schemes for a post quantum world.

INTRODUCTION
Data minimization and selective disclosure (D&S, DataMin, SelDis) are very cool applications of crypto to do magic tricks, such as proving a person is over 25 years old without reveali…
