THORChain Weekly Dev Update #97
THORChain released Weekly Dev Update #97 about Bitcoin Mempool Scanning, Ethereum Symbol Parse Errors and Exploit, MCCN updates, & more.
RAISETHECAPS
The caps were raised to 7m RUNE and filled. The continual Cap Raises give the protocol, middleware and interfaces more and more time to stabilise. Only when the system is stable throughout can the Caps be lifted. At this stage the target is 30m RUNE bonded and 15m RUNE pooled for the system to have caps lifted (this was the maximum seen on SCCN).
Bitcoin Mempool Scanning
~40mb of transactions was suddenly dumped into the Bitcoin mempool. This caused an overload on the Bitcoin block scanner and took out most of the Bitcoin Bifrosts on the network. The fix was to separate mempool scanning from block scanning.

ETH Symbol Parsing Error (1)
A user deposited Maker (MKR) which suddenly caused all ETH Bifrosts to panic and halt. The network was halted for a bug fix to prevent loss of sync. The reason was that the Maker ERC20 is non-standard and returns bytes instead of a string for the memo.

ETH Symbol Parsing Error (2)
A user successfully stole $140k from the network by exploiting a bug in ETH symbol parsing, where a fake ETH could be reported to the network.
This was covered here: ETH Parsing Error and Exploit
