From ca376ead88a5a26626a90abdb62f4de7f6313822 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Felf=C3=B6ldi=20Zsolt?= Date: Tue, 24 Oct 2017 15:19:09 +0200 Subject: les, light: LES/2 protocol version (#14970) This PR implements the new LES protocol version extensions: * new and more efficient Merkle proofs reply format (when replying to a multiple Merkle proofs request, we just send a single set of trie nodes containing all necessary nodes) * BBT (BloomBitsTrie) works similarly to the existing CHT and contains the bloombits search data to speed up log searches * GetTxStatusMsg returns the inclusion position or the pending/queued/unknown state of a transaction referenced by hash * an optional signature of new block data (number/hash/td) can be included in AnnounceMsg to provide an option for "very light clients" (mobile/embedded devices) to skip expensive Ethash check and accept multiple signatures of somewhat trusted servers (still a lot better than trusting a single server completely and retrieving everything through RPC). The new client mode is not implemented in this PR, just the protocol extension. --- les/api_backend.go | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) (limited to 'les/api_backend.go') diff --git a/les/api_backend.go b/les/api_backend.go index 0d2d31b67..56f617a7d 100644 --- a/les/api_backend.go +++ b/les/api_backend.go @@ -174,8 +174,15 @@ func (b *LesApiBackend) AccountManager() *accounts.Manager { } func (b *LesApiBackend) BloomStatus() (uint64, uint64) { - return params.BloomBitsBlocks, 0 + if b.eth.bloomIndexer == nil { + return 0, 0 + } + sections, _, _ := b.eth.bloomIndexer.Sections() + return light.BloomTrieFrequency, sections } func (b *LesApiBackend) ServiceFilter(ctx context.Context, session *bloombits.MatcherSession) { + for i := 0; i < bloomFilterThreads; i++ { + go session.Multiplex(bloomRetrievalBatch, bloomRetrievalWait, b.eth.bloomRequests) + } } -- cgit v1.2.3
