# Update 20 ## week 20 updates This week I spen some time in reading about Verkle Sync: https://hackmd.io/@W3tic1bbRka1R7HA1o1D_A/By_MyNy3h and associated implementation in Nethermind: https://github.com/NethermindEth/nethermind/blob/verkle-sync-devnet-6/src/Nethermind/Nethermind.Synchronization/VerkleSync/VerkleProgressTracker.cs#L115 https://github.com/NethermindEth/nethermind/blob/verkle-sync-devnet-6/src/Nethermind/Nethermind.Synchronization/VerkleSync/VerkleProgressTracker.cs#L101 along with effort of passing 4762 and 6800 spec-tests I will try implementing this process in reth, it will help in further research and benchmarking of Verkle Sync process. I think Besu is looking to implement this, hence will be in touch with them for more information. ## week 21 roadmap Next week I will resume my work on execution spec tests.
