Ricardo Catalinas Jiménez	436fc8d76a	all: Rename crypto.Sha3{,Hash}() to crypto.Keccak256{,Hash}() ... As we aren't really using the standarized SHA-3	9 years ago
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	b6d88a0e9f	core, core/vm, crypto: fixes for homestead ... * Removed some strange code that didn't apply state reverting properly * Refactored code setting from vm & state transition to the executioner * Updated tests	9 years ago

Gustav Simonsson	371871d685	parmas, crypto, core, core/vm: homestead consensus protocol changes ... * change gas cost for contract creating txs * invalidate signature with s value greater than secp256k1 N / 2 * OOG contract creation if not enough gas to store code * new difficulty adjustment algorithm * new DELEGATECALL op code	9 years ago
Péter Szilágyi	1e806c4c77	cmd, common, core, eth, node, rpc, tests, whisper, xeth: use protocol stacks	9 years ago
Gustav Simonsson	220b0bf6e5	Update common test files	9 years ago
Péter Szilágyi	9dc5de51a2	tests: fix data race in bad-block-report disabling during tests	9 years ago

Gustav Simonsson	145366c07e	tests: update JSON files, add new wrappers	9 years ago
Jeffrey Wilcke	80f26086ee	core, tests: get_hash fix ... Make sure that we're fetching the hash from the current chain and not the canonical chain.	9 years ago
Felix Lange	de8d5aaa92	core, core/state: move gas tracking out of core/state ... The amount of gas available for tx execution was tracked in the StateObject representing the coinbase account. This commit makes the gas counter a separate type in package core, which avoids unintended consequences of intertwining the counter with state logic.	9 years ago
Gustav Simonsson	1b1f293082	core/state, core, miner: handle missing root error from state.New	9 years ago
Gustav Simonsson	e1616f77c7	core, core/vm, cmd/evm: remove redundant balance check	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	361082ec4b	cmd/evm, core/vm, test: refactored VM and core ... * Moved `vm.Transfer` to `core` package and changed execution to call `env.Transfer` instead of `core.Transfer` directly. * core/vm: byte code VM moved to jump table instead of switch * Moved `vm.Transfer` to `core` package and changed execution to call `env.Transfer` instead of `core.Transfer` directly. * Byte code VM now shares the same code as the JITVM * Renamed Context to Contract * Changed initialiser of state transition & unexported methods * Removed the Execution object and refactor `Call`, `CallCode` & `Create` in to their own functions instead of being methods. * Removed the hard dep on the state for the VM. The VM now depends on a Database interface returned by the environment. In the process the core now depends less on the statedb by usage of the env * Moved `Log` from package `core/state` to package `core/vm`.	9 years ago

Jeffrey Wilcke	ac697326a6	core/vm: reduced big int allocations ... Reduced big int allocation by making stack items modifiable. Instead of adding items such as `common.Big0` to the stack, `new(big.Int)` is added instead. One must expect that any item that is added to the stack might change.	9 years ago
Jeffrey Wilcke	184e9ae9a8	core, tests: reduced state copy by N calls ... Reduced the amount of state copied that are required by N calls by doing a balance check prior to any state modifications.	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	71d32f54f7	core, miner: added difficulty bomb	9 years ago
Jeffrey Wilcke	03c39d4fc0	tests: updated	9 years ago
Jeffrey Wilcke	9afda6ab8c	core: 5 ether block reward	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
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
Felix Lange	593b1b65e7	tests: document RLP tests	9 years ago
Felix Lange	5da82077d1	cmd/ethtest, tests: add support for RLP JSON tests	9 years ago

Gustav Simonsson	b7e8d954ef	Add TestBcGasPricer, comments and unskip tests	9 years ago
Jeffrey Wilcke	bcc1660abc	core, miner, tests: added test, implemented bad block reporting	9 years ago
Gustav Simonsson	0f04af5916	Fix core error forwarding, unify OOG VM err	9 years ago
Jeffrey Wilcke	ab16ce70fc	core, miner, tests: renamed state methods ... * Update => SyncIntermediate * Added SyncObjects SyncIntermediate only updates whatever has changed, but, as a side effect, requires much more disk space. SyncObjects will only sync whatever is required for a block and will not save intermediate state to disk. As drawback this requires more time when more txs come in.	9 years ago
