1) Test environment, three validators: validator_0: '0x260056e7050afdc2491a343f68b6b10f3302a4a1'; validators_1: '0xf5fea0530dafa59b7a49f2e3539d33d06e7ef6db'; validator_2: '0x064f5cc97da76a83ee28eeb23fab63ad0555ad94' 2) required_signatures = 2 3) We stopped validator_3, since there are 2 of them is running, the conversion still is expected pass 4) Do conversion from DAI to TT-DAI, the transaction is: 0x15282f12f7d56776eec0170e780b707aa8b0b10a0afc8ddc498236ac39706650, corresponding block number is: 12272092 5) After a while, we only get one signature from validator_1, so we checked logs on validator_0. The watcher from block never change, but it got the above Transfer event.
