Third Party Service for Immutable ledger

Third Party Service for Immutable ledger

I have a website with reviews and I am looking for a way to ensure publicly:

  • I never delete any review.
  • I don't change any content.
  • Trusted Timestamping

Basically an Immutable ledger. I don't have infrastructure or size to create my own network, so, I am looking for a third party service that can ensure that for me.

Do you know any service for that?

PS: I see a lot of services, but i don't know exactly if they fit my needs:

bitcoin node: what is the difference between simnet and regtest?

bitcoin node: what is the difference between simnet and regtest? btcd, and presumably other bitcoin node implementations, seem to have 4 network options: mainnet testnet regtest simnet. I get that mainnet and testnet both are "public" in that your node will communicate with other nodes and that both have an existing blockchain and genesis block. However, from what I can tell, both simenet and regtest both create a local only blockchain, and both will create a new genesis block. I this case, what is the difference, and which is better (easier) for developing bitcoin applications? This is what the documentation has to say: --regtest Use the regression test network --simnet Use the simulation test network https://ift.tt/2TAMkwe

How to check if Electrum is masking my IP with the Tor proxy?

How to check if Electrum is masking my IP with the Tor proxy? When i start Electrum from the command line i see this mensage: (python3:7069): dbind-WARNING **: 14:09:58.452: Couldn't register with accessibility bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken What does it mean? I just installed Electrum following this tutorial: http://docs.electrum.org/en/latest/tor.html I followed the instructions from this topic " Option 2: Multiple servers but Tor Main ". I installed Electrum using the command line on Ubuntu, check the " Installation from Python sources " on this link https://electrum.org/#download if you want to see the codes.

When mining with 2 computers, do I need to use 2 separate wallets addresses?

When mining with 2 computers, do I need to use 2 separate wallets addresses? I understand that each miner is working on a different block. Correct me if I'm wrong but this is because the first transaction in a block basically contains my wallet address so I can receive the bonus of solving the block. Obviously everyone wants to receive the bonus so that first transaction will be pointing to everyone's separate wallet addresses. Assume that I have two computers solo mining with both pointing to my wallet address, wouldn't this mean my computers are solving the same block? Continuing with this train of thought, wouldn't that mean that my slower computer is basically useless because it would be generating the same hashes as my faster computer? Now how does this apply to pooled mining? In a pooled community, is everyone solving the same block which has the first transaction pointing to the pool owner who then distributes the coins? http://bit.ly/2SZOBAI
