* rework merkle tree support * deps * rename merkletree -> codexmerkletree * treed and proof encoding/decoding * small change to invoke proof verification * rename merkletree to codexmerkletree * style * adding codex merkle and coders tests * fixup imports * remove new codecs for now * bump deps * adding trace statement * properly serde of manifest block codecs * use default hash codec * add more trace logging to aid debugging * misc * remove double import * revert un-needded change * proof size changed * bump poseidon2 * add from nodes test * shorte file names * remove upraises * wip poseidon tree * adjust file names * misc * shorten file names * fix bad `elements` iter * don't do asserts * add fromNodes and converters * root and getProof now return result * add poseidon2 tree tests * root now returns result * misc * had to make merkletree a ref, because nim blows up otherwise * root returns a result * root returns a result * import poseidon tests * bump * merkle poseidon2 digest * misc * add merkle digest tests * bump * don't use checksuite * Update tests/codex/merkletree/generictreetests.nim Co-authored-by: markspanbroek <mark@spanbroek.net> Signed-off-by: Dmitriy Ryajov <dryajov@gmail.com> * Update codex/merkletree/merkletree.nim Co-authored-by: markspanbroek <mark@spanbroek.net> Signed-off-by: Dmitriy Ryajov <dryajov@gmail.com> * Update codex/merkletree/merkletree.nim Co-authored-by: markspanbroek <mark@spanbroek.net> Signed-off-by: Dmitriy Ryajov <dryajov@gmail.com> * Update tests/codex/merkletree/generictreetests.nim Co-authored-by: markspanbroek <mark@spanbroek.net> Signed-off-by: Dmitriy Ryajov <dryajov@gmail.com> * missing return * make toBool private (it's still needed otherwise comparison won't work) * added `digestTree` that returns a tree and `digest` for root * test against both poseidon trees - codex and poseidon2 * shorten merkle tree names * don't compare trees - it's going to be too slow * move comparison to mekrle helper * remove merkle utils --------- Signed-off-by: Dmitriy Ryajov <dryajov@gmail.com> Co-authored-by: markspanbroek <mark@spanbroek.net>
