From version 1.4 geth has experimental support for pub/sub using subscriptions as defined in the JSON-RPC 2.0 specification.This allows clients to wait for events instead of polling for them.It works by subscribing to particular events.The node will return a subscription id.For each event that matches the subscription a notification with relevant data is send together with the subscription id.Subscriptions are creates with a regular RPC call with eth_subscribe as method and the subscription name as first parameter.If successful it returns the subscription id.Subscriptions are cancelled with a regular RPC call with eth_unsubscribe as method and the subscription id as first parameter.It returns a bool indicating if the subscription was cancelled successful.Fires a notification each time a new header is appended to the chain, including chain reorganizations.Users can use the bloom filter to determine if the block contains logs that are interested to them.In case of a chain reorganization the subscription will emit all new headers for the new chain.

Therefore the subscription can emit multiple headers on the same height.Returns logs that are included in new imported blocks and match the given filter criteria.In case of a chain reorganization previous sent logs that are on the old chain will be resend with the removed property set to true.Logs from transactions that ended up in the new chain are emitted.Therefore a subscription can emit logs for the same transaction multiple times.Returns the hash for all transactions that are added to the pending state and are signed with a key that is available in the node.ethereum march 18When a transaction that was previously part of the canonical chain isn't part of the new canonical chain after a reogranization its again emitted.bitcoin cena 2015Indicates when the node starts or stops synchronizing.bitcoin startups san francisco
