A Solana program that enables trustless inter-blockchain communication between Dogecoin/Bitcoin and Solana by verifying full PoW/AuxPow consensus on chain.
Made with ❤️ by QED
- Full verification of Dogecoin and Bitcoin consensus in a Solana program
- Supports AuxPow/Non-AuxPow blocks for Mainnet and Testnet
- Maintains a constant-memory merkle tree of all blocks processed + 32 latest block cache in memory for convienence
- Supports re-orgs of up to 4 blocks
- Trustlessly read any Dogecoin transaction on Solana using a Merkle Proof
- Trustlessly read any Bitcoin transaction on Solana using a Merkle Proof
- Entire state is zerocopy, so other applications can read from the contract with no overhead by reading in the account
-
QEDDogeChainState::ref_from_bytes(&account.data[33..]).?.get_finalized_block_hash()
-
- Uses zero knowledge proofs for proving scrypt_1024_1_1_256
- very trustless, much ibc

# this is our buffer writer for getting around the 1232 byte tx limit

# sets up a solana ibc program account and appends sends two doge blocks to it
