v6.0.0

Added

• log MinGasPrice and Validator* events (#383)
• support Node.js 12+ (#396)

Changed

• (validator): submit only quorum of CAS signatures. E.g. for 4 validator setup the quorum is 3, so only 3 signatures will be included in CAS even if all 4 validators voted (#389)
• (state): start root chain sync from the last app state, not from genesis. This way we avoid attempt to relay txs for the old events multiple times, plus speed up the startup (#392)

Fixed

• (validator) replay period submissions and restore period proposals on node restart (#403)
• (consensus): should not skip deposits of NFT with zero value (#399)
• (consensus): cannot include multiple epoch length tx in a same block (#407)
• (state): relay events from Bridge just once (#406)
• (validator): period vote checks should account for slot gaps. E.g. for slot list like [0, 1, null, 3] it should figure out the number of slots is 3, even though the epochLength is still 4 (#388)
• (validator): heartbeat service is not submitting txs (#412)
• (consensus): allow to have many deposits in mempool (#411)
• handle failing calls to sendTransaction (#385)
• plasma_getState should return only whitelisted attributes (#408)
• fix tendermint download for some x32 platforms (#401)

v5.5.0 — Multivalidator setup

Added

• (validator) validator sends heartbeat tx every minute (#380)
• (logs) logging for bridge events. Use leap-node:bridge or leap-node:* wildcard (#373)

Changed

• (validator) improved period submission logic: handle underpriced and stuck submissions (#379)

v5.4.0 - 🐲CAS

Added

• (consensus) validators include Cryptoeconomic Aggregated Signatures (CAS) into period submissions. Validators submit a PeriodVote tx for every period and collect votes from other nodes to build CAS bitmap. #305 #315 #318

• (rpc) added plasma_getTransactionByPrevOut. Allows to check if UTXO was spent. #302
• (rpc) added plasma_getPeriodByBlockHeight. The node is storing period information now. docs. #319
• (rpc) added plasma_getState. #344
• (config) added optional CLI argument --dataPath to specify where to store network data. Useful to run multiple leap-node instances on the same machine. #308

Fixed

• (consensus) fixed Epoch Length change issue. #310 #312 #349
• (consensus) testnet resync issues. #333 #351 #361
• (consensus) event subscription reads the same block twice. #348
• (node) period handler / checkBridge is not working. #358

• (rpc) getUnspent excludes exiting utxo now. #339

Removed
