Jeffrey Wilcke	5b283663b4	core: Added new TD strategy which mitigate the risk for selfish mining ... Assuming the following scenario where a miner has 15% of all hashing power and the ability to exert a moderate control over the network to the point where if the attacker sees a message A, it can't stop A from propagating, but what it **can** do is send a message B and ensure that most nodes see B before A. The attacker can then selfish mine and augment selfish mining strategy by giving his own blocks an advantage. This change makes the time at which a block is received less relevant and so the level of control an attacker has over the network no longer makes a difference. This change changes the current td algorithm `B_td > C_td` to the new algorithm `B_td > C_td || B_td == C_td && rnd < 0.5`.	9 years ago
Jeffrey Wilcke	987c1a595a	eth/filters: ✨ pending logs ✨ ... Pending logs are now filterable through the Go API. Filter API changed such that each filter type has it's own bucket and adding filter explicitly requires you specify the bucket to put it in.	9 years ago
Péter Szilágyi	9e011ff1cd	core, eth/downloader: ensure state presence in ancestor lookup	9 years ago
Péter Szilágyi	1cecda8333	core: write individual transactions and receipts too on fast sync	9 years ago
Jeffrey Wilcke	9901a40f04	core: added a new RemovedLogEvent ... When a chain reorganisation occurs we collect the logs that were deleted during the chain reorganisation. The removed logs are posted to the event mux indicating that those were deleted during the reorg.	9 years ago
Péter Szilágyi	1e806c4c77	cmd, common, core, eth, node, rpc, tests, whisper, xeth: use protocol stacks	9 years ago
Péter Szilágyi	e86e0ecdc8	core, eth, miner, xeth: clean up tx/receipt db accessors	9 years ago
Jeffrey Wilcke	a1d9ef48c5	core, eth, rpc: split out block validator and state processor ... This removes the burden on a single object to take care of all validation and state processing. Now instead the validation is done by the `core.BlockValidator` (`types.Validator`) that takes care of both header and uncle validation through the `ValidateBlock` method and state validation through the `ValidateState` method. The state processing is done by a new object `core.StateProcessor` (`types.Processor`) and accepts a new state as input and uses that to process the given block's transactions (and uncles for rewords) to calculate the state root for the next block (P_n + 1).	9 years ago

Péter Szilágyi	b99fe27f8b	core: fix block canonical mark / content write race	9 years ago
Péter Szilágyi	c33cc382b3	core: support inserting pure header chains	9 years ago
Jeffrey Wilcke	6dc14788a2	core, eth/filters, miner, xeth: Optimised log filtering ... Log filtering is now using a MIPmap like approach where addresses of logs are added to a mapped bloom bin. The current levels for the MIP are in ranges of 1.000.000, 500.000, 100.000, 50.000, 1.000. Logs are therefor filtered in batches of 1.000.	9 years ago
Gustav Simonsson	1b1f293082	core/state, core, miner: handle missing root error from state.New	9 years ago
Péter Szilágyi	402fd6e8c6	core, eth, event, miner, xeth: fix event post / subscription race	9 years ago
Jeffrey Wilcke	20ab29f885	core: fixed head write on block insertion ... Due to a rebase this probably got overlooked / ignored. This fixes the issue of a block insertion never writing the last block.	9 years ago
Jeffrey Wilcke	7c7692933c	cmd/geth, cmd/utils, core, rpc: renamed to blockchain ... * Renamed ChainManager to BlockChain * Checkpointing is no longer required and never really properly worked when the state was corrupted.	9 years ago
Jeffrey Wilcke	a6cc02f68f	core: deadlock in chainmanager after posting RemovedTransactionEvent ... This PR solves an issue with the chain manager posting a `RemovedTransactionEvent`, the tx pool will try to acquire the chainmanager lock which has previously been locked prior to posting `RemovedTransactionEvent`. This results in a deadlock in the core.	9 years ago
Felix Lange	70b6174748	cmd/geth, core: make "geth blocktest" work again ... The test genesis block was not written properly, block insertion failed immediately. While here, fix the panic when shutting down "geth blocktest" with Ctrl+C. The signal handler is now installed automatically, causing ethereum.Stop to crash because everything is already stopped.	9 years ago
Felix Lange	a2d5a60418	core, core/state: batch-based state sync	9 years ago
Gustav Simonsson	bfde1a4305	core: Add BadHashErr and test for BadHashes handling	9 years ago
Jeffrey Wilcke	eaa4473dbd	core, core/types: readd transactions after chain re-org ... Added a `Difference` method to `types.Transactions` which sets the receiver to the difference of a to b (NOTE: not a **and** b). Transaction pool subscribes to RemovedTransactionEvent adding back to those potential missing from the chain. When a chain re-org occurs remove any transactions that were removed from the canonical chain during the re-org as well as the receipts that were generated in the process. Closes #1746	9 years ago
Péter Szilágyi	399c920380	core: separate and contain POW verifier, extensive tests	9 years ago

Jeffrey Wilcke	a23478c0be	core, eth, trie, xeth: merged state, chain, extra databases in one	9 years ago
Jeffrey Wilcke	846f34f78b	core/vm, tests: implemented semi-jit vm ... * changed stack and removed stack ptr. Let go decide on slice reuse.	9 years ago
Jeffrey Wilcke	7a75da63c6	core: added default genesis block ... When a user runs a freshly setup geth w/o a database initialised the default genesis block is decoded and inserted in to the database.	9 years ago
Jeffrey Wilcke	acd2c4e520	core: added a running flag to prevent panics in the chainmanager ... The running flag will determine whether the chain manager is still running or not. This will prevent the quit channel from being closed twice resulting in a panic. This PR should fix this issue. Closes #1559	9 years ago
Jeffrey Wilcke	036e6301af	cmd/geth, core, eth: Version 1.0.0 ... Genesis release. Closes #1402 Conflicts: cmd/geth/main.go	9 years ago
Felix Lange	bfbcfbe4a9	all: fix license headers one more time ... I forgot to update one instance of "go-ethereum" in commit 3f047be5a.	9 years ago
Jeffrey Wilcke	8fc9830971	cmd/core,xeth: removed unneeded states & added batch writes	9 years ago
Felix Lange	3f047be5aa	all: update license headers to distiguish GPL/LGPL ... All code outside of cmd/ is licensed as LGPL. The headers now reflect this by calling the whole work "the go-ethereum library".	9 years ago
Jeffrey Wilcke	e17d8ddbeb	core: during chain reorg rewrite receipts and transactions ... Added PutBlockReceipts; storing receipts by blocks. Eventually this will require pruning during some cleanup cycle. During forks the receipts by block are used to get the new canonical receipts and transactions. This PR fixes #1473 by rewriting transactions and receipts from the point of where the fork occured.	9 years ago
Jeffrey Wilcke	a32c51effd	cmd, core, eth, common: genesis preparation ... Implemented the --genesis flag thru which we can set a custom genesis block, including the official Ethereum genesis block.	10 years ago

Jeffrey Wilcke	2feb23c1da	core, eth, miner, xeth: receipt storage fix ... * Added GetReceiptsFromBlock, GetReceipt, PutReceipts * Added ContractAddress to receipt. See #1042	10 years ago
Jeffrey Wilcke	29e2fb38f8	core, miner: miner header validation, transaction & receipt writing ... * Miners do now verify their own header, not their state. * Changed old putTx and putReceipts to be exported * Moved writing of transactions and receipts out of the block processer in to the chain manager. Closes #1386 * Miner post ChainHeadEvent & ChainEvent. Closes #1388	10 years ago
Jeffrey Wilcke	70d5d791cc	core, cmd/geth: improved recover functionality ... `geth recover` now accepts both hashes and numbers using "#" and no longer requires the ethereum instance.	10 years ago
